Welcome to the 2014 Executive Conference
Beyond the Boundaries:
Opportunities in Forest Bioproducts March 13, 2014 Dear Friends, It is my pleasure to welcome you to our 2014 Executive Conference, “Beyond the Boundaries: Opportunities in Forest Bioproducts.” Building on last year’s look to the future, the 2014 conference will explore emerging materials and product opportunities. We will discuss improvements companies can consider in manufacturing operations and product portfolios. We will share progress in our current manufacturing improvement projects and delve into some intriguing possibilities for future investigation. The industry’s future will not be built solely on products and mills—it will require dynamic, multifaceted leadership. We will provide several opportunities for interactions with our students, and discuss developments and plans for the unique IPST educational programs to prepare those leaders for future challenges in forest bioproducts. Mills, people, and products have to have access to the marketplace. As usual, we will offer exposure to expertise at Georgia Tech in business development, and commercialization opportunities. We emphasize that this event will be a conference—more than a series of presentations with brief Q&A. We encourage your engagement during several discussions, breakouts, and workshop activities we will feature. While you are here, we hope you will visit the Robert C. Williams Papermaking Museum. The Museum is a popular destination for students, teachers, and members of the general public, and we invite you to visit our latest exhibits. Beyond the boundaries—of conventional products and processes; of traditional education; of forest products industry product portfolios and partners. I am delighted to have you with us as we explore this year’s critical topics, and I look forward to hearing your thoughts.

Huibin Chang Materials Science & Engineering PSE Grad Student as of Sep 2013 Expected completion: Aug 2017 Graduate Research Assistant [email protected] Strategic Area: New Materials or Products Thesis: Carbon Fibers from Polyacrylonitrile (PAN)/Cellulose Nano Crystals (CNC) Advisor: Satish Kumar
Carbon fibers are widely used in high-strength, low-density composite materials. Among different precursors, polyacrylonitrile (PAN) is the predominant precursor for carbon fiber production. In order to increase the tensile strength and modulus of PAN-based carbon fibers, one effective way is to add reinforcement materials with higher mechanical properties to PAN matrix. Cellulose is the most abundant renewable polymer in the biosphere. Cellulose Nano Crystals (CNCs), which have a near-perfect crystal structure, possess high tensile strength (up to 7.5 GPa) and high tensile modulus ( in the range of 110 – 220 GPa). By comparison, the tensile strength and modulus of PAN precursor is about 1 GPa and about 20 GPa. It is hypothesized that the incorporation of highly ordered, high strength and high modulus CNCs will contribute to further increase strength and modulus in PAN-based carbon fiber. The purpose of this research, therefore, is to process PAN/CNC nano composite fibers and to convert them into carbon fiber. PAN/CNC nano composite fibers will be gel-spun using solvents such as dimethyl formamide (DMF), dimethyl acetamide (DMAc), and dimethyl sulfoxide (DMSO). Cellulose Nano Crystals (CNCs) in a broad concentration range will be used. Fibers will be stabilized in air and carbonized in inert environment under the maximum tension that fiber can bear. Precursor fiber and their stabilized and carbonized products will be characterized and tested and the optimized experimental parameters for PAN/CNC nano composite fibers will be obtained.

Xiaotang Du Chemical and Biomolecular Engineering PSE Grad Student as of Oct 2012 Expected completion: May 2012 [email protected] Strategic Area: Operations Excellence Thesis: Novel Technology for Microstickies, Fatty Acids and Residual Ink Removal in Waste Stream Advisor: Jeff Hsieh
Some paper mills have suffered from low product quality and long machine down-time due to microstickies and inkjet ink. Current pulping and cleaning methods cannot solve these problems and it is necessary to develop some novel technology to remove microstickies, fatty acid and ink at low energy level. Microstickies cause deposits in paper-making recycling processes, which lowers the paper product quality and increase the downtime of paper mill. Microstickies are in the size range of 100-150 micrometers or lower. Current methods of its removal include microfiltration, pressure screening, and flotation. The experiments using samples containing mill stickies did not provide a complete mechanism understanding due to its very complex compositions, which kept us from developing effective removal methods. This study is focused on the buildup of model system, investigation of structure-property relationship and removal methods. From my current research results, microstickies migration induced by electric field could improve the coagulation of microstickies and improve the removal efficiency. Flotation deinking has had difficulties in removing hydrophilic ink due to their affinity to water and submicron size. The inkjet ink will redeposit onto the lumen of fiber that cannot be removed. Adsorption deinking during pulping could prevent the redeposition process. Surface treatment to change its property and increase their size could also be effective method to remove the inks. In addition, liquid plasma could irreversibly increase the size of ink particles via free radical polymerization. The polymerized ink could also be separated by filter paper. Separation of fatty acid from white water, vegetable oils and biodiesel acid is also an important problem. Industry uses iron oxide nanoparticles to adsorb fatty acids with its separation from the solution using a magnet. Previous results of liquid plasma could increase the particle size and reduce the amount of nanoparticles. Other novel technologies like electric field may also be a possible method for separation. Overall, the project focused on new separation technology for microstickies and residual ink. Furthermore, a scientific model and fundamental experiments about coagulation mechanism by electric field are also necessary to optimize the reaction condition for application.
Xu Du Chemical and Biomolecular Engineering PSE Grad Student as of Fall 2013 Expected completion: Fall 2018 [email protected] Strategic Area: New Materials Products Thesis: Lignin Based Green Polyurethanes from 100% Sustainable Natural Materials Advisor: Yulin Deng
Polyurethanes are important in our modern lives, which are widely used in construction, packaging, insulation, upholstery, footwear, vehicle parts, painting and so on. However, the material has some drawbacks including poor degradability and toxicity due to the use of isocyanates. Therefore, it is necessary to find more environmentally friendly starting materials and synthesize sustainable polyurethanes products with environmentally friendly pathways. The project will study an alternate way to synthesis polyurethanes using sustainable lignin and other 100% sustainable natural materials as the starting materials. The research will reveal the fundamental understanding of the chemistry of the synthesis and the physical properties of the final products.

Michael Dutzer Chemical and Biomolecular Engineering PSE Grad Student as of Spring 2013 Expected completion: Spring 2017 [email protected] Strategic Area: Operations Excellence Thesis: Low-Cost Carbide-Derived Carbons for Adsorptive Removal of VOCs from Air Streams Advisor: Krista Walton
Carbide-Derived Carbons (CDCs) offer the possibility of using a low-power adsorbent to remove volatile organic compounds from the paper-making process. CDCs are ideal for this process as they allow tunable pore size, a narrow range of pore sizes, and chemical selectivity. These properties of CDCs are achieved through the selection of a metal carbide followed by etching away the metal within the metal carbide with a high temperature halogenation process, leaving behind a carbon complex with a narrow distribution of pore sizes. The goal of this proposal is to finely tune this adsorption process for specific VOC emissions important to achieving the paper industry’s environmental goals.
Christine Dykstra Civil & Environmental Engineering PSE Grad (minor) Student as of June 2012 Expected completion: May 2016 [email protected] Strategic Area: Operations Excellence Thesis: Fate and Biotransformation Potential of Phytosterols in Pulp-and-Paper Wastewater Treatment Systems Advisor: Sujit Banerjee, Spyros Pavlostathis
Phytosterols are naturally occurring compounds that are produced by plants and serve a structural and regulatory function in the cell membrane, as well as acting as a precursor to the synthesis of plant growth hormones. The phytosterol structure is based on a four-ring steroid molecule that is decorated with a hydroxyl group and a side chain. Similar in structure to cholesterol, phytosterols differ by the attachment of functional groups and/or the presence of double bonds on the aliphatic side chain. Phytosterols have been linked to endocrine disruption in both aquatic and terrestrial animals, which may be a concern when released in elevated concentrations to a receiving body of water. During the pulping process, phytosterols are freed from wood fibers and released into wastewater, which is commonly treated in aerated stabilization basins (ASBs). Within a typical ASB, there is a range of redox conditions from aerobic near the aerated zone, to anaerobic within the sediment layers. There is evidence of phytosterol biotransformation under aerobic and denitrifying (anoxic) conditions but less is known about their fate under anaerobic conditions or within systems containing multiple redox zones. Additionally, the hydrophobicity and limited solubility of phytosterols indicate significant partitioning to solids may occur, resulting in a possible accumulation of phytosterols in ASB sediment. This research aims to examine the fate and biotransformation potential of the three most prevalent phytosterols (beta-sitosterol, stigmasterol and campesterol) under variable redox conditions and evaluate the potential for different treatment conditions to reduce endocrine disruption linked to pulp mill wastewater.
Jessica Ewbank Chemical and Biomolecular Engineering PSE Grad Student as of Oct 2010 Expected completion: Dec 2014 Graduate Research Assistant [email protected] Strategic Area: Biorefining Thesis: Design and Synthesis of Catalysts for Catalytic Conditioning of Biomass Derived Syngas Advisor: Carsten Sievers
My research focuses on tar reforming of biomass derived syngas. Syngas derived from biomass offers the chance to produce renewable, carbon neutral fuels. Tars are currently defined as condensable aromatics and are found in a much higher concentration in biogas than syngas derived from coal. Tar reforming is the bottleneck in utilization of biomass derived syngas. Tars can clog process lines, foul equipment, and hinder further processing of syngas. My work focuses on rational design of catalysts used for this application in order to successfully correlate catalytic activity with tar reforming capabilities. Tar reforming is being investigated under closely modeled syngas compositions and long on-stream studies are a major focus.

Alexandra Firebaugh Materials Science & Engineering PSE Grad Student as of Sep 2013 Expected completion: Sep 2017 Graduate Research Assistant [email protected] Strategic Area: Operational Excellence Thesis: Corrosion Behavior of New Lean Duplex Stainless Steels in Changing Pulp and Paper Mill Environments Advisor: Preet Singh
Recently, new lean duplex stainless steel grades 2003, 2101, 2102, 2120, and 2404, have been developed which have lower alloying than the traditional 2205 and 2304 grades but have superior corrosion and mechanical properties compared to more traditionally used austenitic stainless steels. However, corrosion behavior of these alloys have not yet been used or evaluated in pulping liquors or paper machine environments. This PSE student project will focus on fundamental understanding of repassivation behavior and film characteristics in selected range of environmental parameters as a function of alloying so that selection of materials for the modern pulp and paper industry can be based on reliable data. Effect of microstructural features formed during fabrication of equipment in heat affected areas in specific process streams of the pulp and paper mill is also not known. New LDSS alloys have potential to provide cost-effective solution to corrosion problems in modern pulp mills and this study will provide much-needed information to utilize that potential of these new alloys. Work will involve in-situ analysis of passive films formed on the steel surface by coupling electrochemical testing with characterization methods to identify the corrosion mechanisms. Tested corrosion samples will be further characterized for the mode of corrosion. Electrochemical methods including DC-polarization and electrochemical impedance spectroscopy (EIS) methods will be used to investigate the effect of different extraction methods on corrosion behavior of selected steels. Film formed at the surface of steel samples will be characterized by scratch tests using chronoamperometry as well as EIS. Physical and chemical characterization of films formed under different environments will be studied by using XRD, EDS, XPS, and AFM methods.

Zack Heidemann Mechanical Engineering PSE Grad Student as of Jan 2008 Expected completion: Summer ‘14 Graduate Research Assistant [email protected] Strategic Area: Operations Excellence Thesis: A Fluidics Approach to Functional Encapsulation of Developing Somatic Embryos of Norway Spruce (Picea abies) Advisor: Cyrus Aidun
Somatic embryogenesis (SE) is widely considered to be the only feasible system to meet future needs for large-scale production of elite plants for agricultural and forestry practices (Von Arnold and Clapham 2007). Somatic embryogenesis is the process by which somatic cells in the plant are removed and are coaxed into forming an embryogenic callus from which the cells can be matured and regenerated into full plants (Von Arnold and Clapham 2007). Efforts are under way to improve the laboratory protocols for proliferation and maturation of somatic embryos. Important contributions can be made by applying engineering solutions to facilitate growth and development of somatic embryos, and establish a platform for automation of the SE process. For proper development into a plant, the somatic embryos require nutrients and growth regulators that are supplied by the culture medium. The most efficient method for delivering these chemicals is via liquid suspension culture versus culture on gelled medium. However, plant somatic embryos in vitro are adversely affected by the mechanical stress from the liquid suspension culture. The rotating and deforming liquids destroy the polarity of multiplying somatic embryos that is required for successful embryo maturation (Sun et al. 2010). Efficient scale-up of processes producing mature embryos in liquid culture bioreactors is thus not possible. Encapsulation of a single embryonic cell or cluster in a “micro- environment” allows greater control of the environmental signals the embryo(s) receive. An enclosed system not only would simplify handling of somatic embryogenesis, it could also serve as an artificial seed provide that could be planted directly.
Aaron Howell Mechanical Engineering PSE Grad Student as of Sep 2011 Expected completion: Spring 2014 Graduate Research Assistant [email protected] Strategic Area: Operations Excellence Thesis: Development of a Black Liquor Evaporation Method to Eliminate Fouling Advisor: Cyrus Aidun
Black liquor is a valuable source of energy in the paper mill but, as it leaves the pulper, black liquor is not fit to be burned because it contains far too much water. The current solution is to condense the black liquor in a falling film or rising film evaporator. In either of these arrangements, scale deposits on the heat transfer surfaces. The fouling of the surfaces reduces the effectiveness of the heat transfer, requiring additional energy, and effort must be periodically taken to clean the evaporator surfaces. This project seeks to determine a method for evaporating the black liquor as a suspended liquid, by applying hot air or superheated steam directly on the liquor. The elimination of the heat transfer surface removes the potential for scale formation and will allow the evaporator to operate in more consistent manner.
Fan Hu Chemistry and Biochemistry PSE Grad Student as of Jul 2008 Expected completion: Fall 2014 Graduate Research Assistant [email protected] Strategic Area: Biorefining Thesis: Pseudo-Lignin Chemistry Advisor: Art Ragauskas
It is generally accepted that incorporation of polysaccharide destruction products into lignin forms a lignin-like material termed pseudo-lignin during dilute acid pretreatment (DAP). My research has demonstrated that pseudo-lignin can be generated from cellulose and/or hemicellulose without significant contribution from lignin during DAP. My thesis contributes to the acquisition of knowledge by providing characterization of extracted pseudo-lignin from pretreated holocellulose and cellulose; proposing possible mechanisms of pseudo-lignin generation; and providing the reaction conditions (temperature, acid concentration and the presence of oxygen) associated with the mechanisms in order to diminish the amount of pseudo-lignin generation. More important, the formation of pseudo-lignin spherical droplets on the surface of pretreated carbohydrate reveals the possibility that those droplets may occlude pore structure and block enzyme accessibility or even bind to enzymes. Therefore, the study of pseudo-lignin/enzyme interaction will be significant for enzymatic deconstruction of cellulose and the determination of pretreatment conditions.

Chad Hume Mechanical Engineering PSE Grad Student as of Aug 2013 Expected completion: May 2017 [email protected] Strategic Area: Operational Excellence Thesis: Hole Design and Manufacture for Press Fabric Layers to Improve Dewatering Advisor: Dave Rosen
During paper manufacturing, one of the main energy consumers is drying the paper web. Energy consumption could be greatly reduced if web dewatering efficiency could be improved. This proposal will explore methods for increasing dewatering efficiency in press fabrics in a two-pronged manner. First, a systematic investigation will be performed of water flows in press fabrics through computational fluid mechanics (CFD) with the objective of designing geometric features that aid dewatering. Second, a novel ink-jet printing technology will be applied to the fabrication of the designed feature geometries.

Nikita Kevlich Chemical and Biomolecular Engineering PSE Grad Student as of Oct 2013 Expected completion: Dec 2017 Graduate Research Assistant [email protected] Strategic Area: Operational Excellence Thesis: Advanced Membranes for Energy-Efficient Concentration of Spent Pulping Liquors in the Kraft Process Advisor: Sankar Nair, Meisha Shofner
Large amounts of energy are required for the concentration of black liquor in the Kraft papermaking process, with the paper-making industry consuming about 1% of the annual United States energy usage just for this unit operation. Membranes have the potential to significantly reduce this energy consumption, with annual savings anticipated to be over a billion dollars. However, current membranes are not robust under the harsh black liquor conditions (pH>12, temperature between 80-90°C, many fouling species). The goal of this project is to design zeolite and/or carbon-based membranes that can withstand these harsh conditions while efficiently concentrating black liquor from 15% solids to about 35% solids. It is envisioned that two different membranes of different pore sizes will first separate the many high-molecular-weight chemical species and other fouling agents, and then separate the lower-molecular weight species from water; thereby concentrating the black liquor and recovering much of the water.

Advanced characterization of lignin and testing of various properties of pulps and handsheets are performed.
Stephanie Lin Materials Science & Engineering PSE Grad Student as of Jan 2011 Expected completion: Spg 2014 Graduate Research Assistant [email protected] Strategic Area: Biomaterials Thesis: Crystallization Kinetics of Cellulose-Based Nanocomposites Advisor: Meisha Shofner
This research seeks to process and characterize cellulose-based nanocomposites to further explore the structure-property design space available in these materials. Specifically, the research will be structured to test the effect of high aspect-ratio cellulose nanocrystals on the crystallization kinetics of the semicrystalline biopolymer matrix polyhydroxybutyrate (PHB), thus increasing the mechanical modulus and toughness concomitantly. If successful, this research will lead to the development of new materials with reduced environmental impact and unique combinations of properties that are unavailable in other materials. Additionally, the specific materials proposed will provide opportunities to increase the application range of PHB polymers and more fully describe the impact of the nanofiber aspect ratio on crystallization and mechanical properties. This fundamental understanding will provide insight into other types of polymer nanocomposites and provide guidelines for nanofiber composite design.

Hsiang-Hao Liu Materials Science & Engineering PSE Grad Student as of Oct 2012 Expected completion: May 2016 [email protected] Strategic Area: Biomaterials Thesis: Novel Carbon Fibers and Films using Lignin and Carbon Nanotube Precursors Advisor: Satish Kumar
Carbon fibers are currently being used in aerospace structures, wind-mill blades, for sports goods, as well as for automobile applications. Carbon fiber market is growing annually at the rate of 10 to 12%. Currently there are two major driving forces for the carbon fiber research and development: (1) to achieve carbon fiber mechanical properties closer to their theoretical potential. (2) To reduce the raw material and production cost of carbon fiber. To increase fiber mechanical properties, carbon nanotubes (CNT) are being added in the carbon fiber precursor such as polyacrylonitrile (PAN). To reduce cost, there is significant research and development activity to produce carbon fibers from lignin. To balance cost and mechanical properties, carbon fibers can also be produced with blends of PAN, CNT, and lignin. In this project, hardwood lignin (HWL), polyacrylonitrile (PAN), and CNT blend fibers are being spun using gel-spinning at various HDL, PAN, and CNT ratios. Other spinning approaches such as melt- and solution-spinning will also be considered. The precursor fibers will be stabilized and carbonized in the batch process under appropriate conditions. The overall objective of the project will be to assess the effect of various material compositions and processing parameters on the development of the structure, morphology and properties of the precursor fiber, the final carbon fibers, as well as their intermediate products.
Yitao Liu Mechanical Engineering PSE Grad Student as of Aug 2012 Expected completion: Spring 2016 [email protected] Strategic Area: Manufacturing Systems Thesis: Optimal Resource Balancing and Factory Loading for Energy Cost Reduction in the Pulp and Paper Industry Advisor: Roger Jiao
This research will adopt an industrial systems engineering approach to total energy management in pulp and paper production.

The technical approach is to develop advanced Operations Research and Production Planning decision models, algorithms and simulation tools to optimize factory loading allocation while balancing energy usage. The focus will be an individual equipment-level energy management, as well as plant-wide integrated strategies, covering all aspects of energy planning, operation and reporting. The deliverable will be energy planning software tools, including factory load planning to predict energy consumption, economic flow network model to balance energy consumption and supply, linear programming/mixed integer programing optimization to solve economic flow network models, and what-If scenarios and simulation to evaluate and compare alternative operational strategies.
Sarah McNew Schimming Chemical & Biomolecular Engineering PSE Grad Student as of May 2010 Expected completion: August 2014 Graduate Research Assistant [email protected] Strategic Area: Biorefining Thesis: Production of High-Octane Fuels from Pyrolysis Oils Advisor: Carsten Sievers
My research focuses on understanding chemical engineering principles and reaction mechanisms to design catalysts to upgrade pyrolyis oils by hydrodeoxygenation. These oils can be produced from any kind of organic feedstock including waste stream from the forest products and agricultural industry. However, many compounds in these mixtures are not stable enough to be transported and the resulting mixture contains chemicals that will impede direct use of the mixture as a fuel. I am working on synthesizing sulfur-free heterogeneous catalysts to increase the stability and improve the quality of the bio-crude oil. The synthesis method and composition of the catalysts will be optimized based on characterization with a variety of physico-chemical techniques. Promising catalysts are tested on model compounds and the products are analyzed as the operating conditions of the reaction vary. These catalytic reactions are performed in a continuously operated fixed bed reactor.

The aim of this project is to develop and characterize a water- based processing method using traditional shear processing on an aqueous gel composed of cellulose nanocrystals and a water-soluble polymer. It is believed that hydrogen bonding leading to physical crosslinking will hold the gel together and allow for bond breakage and reformation between the polymer and filler during processing. This goal will be accomplished through rheological, mechanical, thermal, and optical characterization to determine material compatibility and feasibility with traditional melt processing equipment as well as performance after processing.

My research focuses on understanding chemical engineering principles and reaction mechanisms to design catalysts to conversion any kind of organic feedstock into biofuel. Due to the complex composition of the biomass, the mechanism of the reaction is hard to describe. The catalyst will be optimized according to the reaction result. These catalytic reactions are performed in an autoclave batch reactor.
Arie Mulyadi Chemical & Biomolecular Engineering PSE Grad Student as of Aug 2012 Expected completion: Aug 2016 [email protected] Strategic Area: Biomaterials Thesis: Chemical Surface Modification of Nanocellulose Advisor: Yulin Deng
Cellulose nanocomposites have been of great interest recently to industry as low-cost engineering materials and as an alternative reinforcement to more expensive nanoparticles, such as carbon nanotubes. However, optimal properties of these materials have not been achieved successfully. Key challenges toward improved performance of nanocomposites are better nanoparticle/matrix interfacial adhesion and homogeneous dispersion of end product. Surface modification of cellulose nanofibers would be required to potentially overcome these challenges. One of the important methods of surface treatment for cellulose nanofibers is chemical grafting. The grafted cellulose nanofibers would change the properties of cellulose nanofibers from hydrophilic to hydrophobic. This change would limit the hydrogen bond interaction, reduce agglomeration affinity, improve water resistance, and potentially improve the dispersibility of nanofibers in organic solvents. This surface modification also opens the door for the use of cellulose nanofibers for non-polar polymer reinforcement. Improving the hydrophobicity would improve the interfacial interaction between nanofibers and non-polar polymer matrix. The effects of incorporating the modified nanofibers into polymer matrix would show improved properties such as high strength, low moisture adsorption, and high thermal stability.

The goal of my study is to investigate the gasification behavior of three different biomass candidates: loblolly pine, switchgrass, and corn stover. These three biomass species differ in their composition, particularly in the alkali content which plays a catalytic role in the gasification of char. The aim is to optimize gasifier design and conditions for syngas production from these feedstocks while minimizing tar and hydrocarbon contaminants in raw product gas. It is anticipated that the results from this work would provide a set of guidelines for other biomass candidates as well. The proposed work will provide a new option to produce value-added products from by-products in the paper and forest products industry, including branches, bark and forest residue.

These materials will be used as packaging for foodstuffs, pharmaceuticals, medical items and even dry good such as paper as well. The barriers will protect against water, oil and grease, oxygen and aroma. In some cases the barriers will also have excellent gas resistance.
James Silva Mechanical Engineering PSE Grad Student as of Aug 2012 Expected completion: May 2017 [email protected] Strategic Area: Operations Excellence: New Pulp and Paper Product Thesis: Thermomechanical Behavior of a Constrained Gel Interface for Heat and Moisture Management Advisor: Andrei Fedorov
Dynamic control of interfaces (shape and thermo-mechanical properties) in response to external stimuli (temperature or relative humidity, for example) is compelling for a number of applications involving management of flow, heat and mass transfer. In particular, a hydrogel system, such as poly-(N-isopropylacrylamide) or PNIPAM, provides a good example of a temperature-responsive material, which undergoes a significant change of volume by imbibing water from the external environment in the course of phase transition from its dry (shrunken) state to the solvated (swollen) state as the temperature is reduced below its lower critical solution temperature (LCST). This phase transition behavior in polymer-water system can be exploited to modify (reduce) the saturation temperature for condensation or produce thermo-mechanical actuators capable of a macroscopic range of motion. In this research, the PNIPAM phase-transition in response to changes in temperature and relative humidity of an environment near saturation conditions are examined through thermodynamic analysis and experimental observations using optical and environmental electron microscopy (ESEM). Characterization is not limited expansion/contraction of free-standing gels, including those constrained in one or two dimensions. The prediction of the model inspired by recent developments will be compared to experimental observations and critically discussed. Potential applications of the spatially-constrained temperature-responsive polymers focus on thermal-fluid management of bioreactors and biosensors.
Qining Sun Chemistry and Biochemistry PSE Grad Student as of Jan 2011 Expected completion: Dec 2014 [email protected] Strategic Area: Biomaterials Thesis: Lignin Effect on Biomass Structural Change During Pretreatment to Understand Biomass Recalcitrance Advisor: Art Ragauskas
Qining is a PhD candidate in the School of Chemistry and Biochemistry at Georgia Tech with R&D experience in wood adhesive, fire retardant, biofuel, and sustainable forestry products. His doctoral research covers a range of topics from lignin effect on biomass structural change during pretreatment to understand biomass recalcitrance and boost biofuel production. His work aims first to establish the effect that several leading pretreatment technologies have on cellulose ultrastructure in poplar, a prospective energy crop, as it relates to changes in enzymatic hydrolysis; second, to investigate the lignin effect and redistribution on cellulose ultrastructure during dilute acid pretreatment; and third, to isolate and monitor lignin chemical structural change during pretreatment. In addition, he is also interested in isolating biomass cellulose crystalline parts as cellulose nanowhiskers to prepare novel biodegradable films and foams with hemicellulose and crosslinkage.

Zhenguan Tang Chemical and Biomolecular Engineering PSE Grad Student as of Aug 2011 Expected completion: Dec 2015 [email protected] Strategic Area: Fabrication of Oleophobic Surface on Porous Substrate Using Non-fluorinated Materials Advisor: Victor Breedvelt, Dennis Hess
Fluorinated chemicals have long been known to have better oil repellence relative to other chemicals, which is largely due to their low surface energies. Although this property makes fluorinated chemicals great candidates to impart oleophobicity to paper, the disadvantages of fluorinated chemicals are also obvious: fluorinated chemicals present environmental and human health issues. Because of the high strength of the carbon-fluorine bond, fluorocarbons cannot be degraded naturally and are persistent in the environment. Some categories of fluorinated compounds, such as chlorofluorocarbons, participate in ozone depletion. Fluorocarbons are also potent greenhouse gases. Besides these environmental issues, fluorine-based chemicals are also expensive to manufacture and process. Due to all these disadvantages, there is a global effort to reduce the use of fluorinated materials in industry. My project focuses on fabrication of oil-resistant paper using non-fluorinated coating materials so that the use of fluorinated chemicals in paper industry could be further reduced.

Prateek Verma Materials Science & Engineering PSE Grad Student as of Aug 2011 Expected completion: Jul 2015 [email protected] Strategic Area: Biomaterials Thesis: Deconstructing the Auxetic Behavior of Paper Advisor: Anselm Griffin, Meisha Shofner
We are working on the auxetic (negative Poisson’s ratio) response of cellulose based fiber networks. Auxetic materials grow fatter when stretched and are extremely rare in nature. It has been reported that fibrous paper increases in thickness when stretched in planar direction. Recently, researchers have also induced auxetic behavior in polyurethane foams, expanded PTFE and ultra-high-molecular-weight polyethylene. By measuring the thickness variation with stretch in different types of paper, we determined their Poisson’s ratio to be negative (0 to -3.0). We propose that the mechanism of this auxetic response stems from the non-woven network structure of cellulose fibers having rich hydroxyl surface. During compressive stages of papermaking, hydrogen bonding between fibers locks them into a crumpled microstructure which expands when stretched. Auxetic behavior arising from surface chemistry of polymeric fiber networks is a novel concept that can potentially be applied to new material designs and product development techniques.
Yushu Wang Materials Science & Engineering PSE Grad Student as of Oct 2011 Graduate Research Assistant [email protected] Strategic Area: Operations Excellence Thesis: Corrosion of Stainless Steels in Closed Paper Machine Environments Advisor: Preet Singh
Closed or partially closed chemical process system helps reduce fresh water usage as well as process water discharge in the pulp and paper industry. However, water properties change due to the recycling of process water, which can promote corrosion of existing equipment. Higher temperatures, changes in pH along with higher levels of residual chemicals, additives, and suspended solids all aggravates the corrosion. Different kinds of corrosion, such as pitting, stress corrosion, microbial corrosion, erosion-corrosion, etc., can happen at the same time. The purpose of this research is to understand the corrosion behavior of 304L, 316L and duplex stainless steels in white-water systems. The understanding of fundamental mechanisms of corrosion and stress corrosion cracking in white-water systems will lead to possible process optimization or facility improvement such as corrosion inhibitor or change of metal used in equipment.

Jie Wu Materials Science & Engineering PSE (minor) Grad Student as of Aug 2009 Expected completion: Spg 2014 Graduate Research Assistant [email protected] Strategic Area: New Products Thesis: Optical Coatings via Biomimicry for Sustainable Paper and Paperboard Products Advisor: Carson Meredith
Paper and paperboard require significant whiteness and brightness so that printed images and text can achieve maximum optical contrast with faithful color reproduction. Traditional approaches to attain that goal have included lignin extraction, addition of mineral fillers and bleaching treatments that involve energy-intensive processes that produce additional waste streams and add additional mineral mass in the final product. A recent discovery indicates that a three-dimensional random network structure makes the white beetle have high whiteness and brightness. The project goal is to develop assembly methods for reproducing this white beetle scale structure synthetically and extend this approach to coat paper and paperboard products.
Brian Min Yun Biomedical Engineering PSE (minor) Grad Student as of Aug 2005 Expected completion: May 2014 Graduate Assistant [email protected] Strategic Area: Operations Excellence Thesis: Simulations of Pulsatile Flow through Bileaflet Mechanical Heart Valves Using a Suspension Flow Model: To Assess Blood Damage Advisor: Cyrus K. Aidun, Ajit P. Yoganathan
Prosthetic heart valves have been used for over 50 years to replace diseased native valves. The most widely implanted design is the bileaflet mechanical heart valve (BMHV) due to superior flow hemodynamics and blood damage performance. However, BMHVs still lead to severe complications such as hemolysis, platelet aggregation, and thromboembolic events. These problems have been linked to non-physiological shear stresses on blood elements. In order to reduce the severity of the complications and improve valve design, the blood damage that occurs in BMHV flows must be well understood. Computational fluid dynamics solvers can be used to model blood damage in pulsatile flows through BMHVs and ultimately improve valve design. The numerical simulations of this study employ a fluid-solid coupling method that combines the lattice-Boltzmann Method (LBM) with the novel external boundary force (EBF) method. The LBM solution for fluid flow converges to the solution of the Navier-Stokes equations. In addition to being accurate, the LBM employs spatially local calculations due to roots in kinetic theory, making it optimal for parallel computing. The motion and orientation of suspended solid particles are captured solving the Newtonian dynamics equations. Fluid-solid coupling is computed using the EBF method by enforcing no-slip conditions on all solid surfaces. A linear shear stress-exposure time damage accumulation model can be used to quantify platelet damage.

Modern technology requires electronic devices to be more flexible and environmental friendly, which makes cellulose to be a candidate to fabricate electronic devices. In my study, two different cellulose based electronic devices will be studied. For the first part, an ionic paper-based diode (IPD) was made by combining together two oppositely charged microfibrillated cellulose sublayers. The asymmetric charge distribution between the two sublayers will help selectively transport cations and anions under positive and negative bias, to allow an electric current to pass in only one direction. For the second part, flexible and free-standing supercapacitors made mainly by multi-walled carbon CNTs) and micro-fibrillated cellulose (MFC) was investigated. The results indicated that the as-made supercapacitor showed a high specific capacitance of 176mF/cm. In addition, the electrochemical properties of the supercapacitors remained almost the same under severe bending. In sum, cellulose-based electronics have good characteristics of being low-cost, green and flexible and can be applied in various areas, such as supercapacitors, transistor, solar cells, etc.

High-strength, low-weight foams are important in a variety of applications, ranging from thermal insulation to packaging, and biocompatible foams are desired as drug delivery vehicles and scaffolds for tissue engineering. However, traditional polymer foams based on petroleum are neither renewable nor biodegradable. Cellulosic foams, however, can fulfill these requirements. My goal is to develop a novel method to produce high-strength, low-weight cellulosic foams from colloidal assembly.

IPST Analytical and Testing Services IPST at Georgia Tech Analytical and Testing Services include chemical analysis, paper physical analysis, materials analysis, microscopy, pulp analysis, gasification, and chemical recovery. The Testing Services group oversees all activities related to research testing capabilities for Georgia Tech internal and external clients on a fee-contract basis. The dedicated research laboratories are led by seasoned professional scientists and engineers representing many decades of combined industrial and research experience with accomplished research and publication records in their respective fields. Collaboration on projects within this unique multidisciplinary group make the team particularly qualified to expedite resolution of customers' technical requirements in the areas of process or product development and quality control. The combination of four dedicated fully equipped laboratories and established research experience provide the forest products industry with an optimal readily available resource to assist with all technical issues. Chemical Analysis Laboratory (Mike Buchanan) The activities of the Chemical Analysis Group range from routine testing services to research. Some specific areas of experience include machine deposit; evaporator scale and product contaminant chemical characterization; wood, pulping liquor, pulp and paper chemical analysis; product defect analysis; and methods development. To support this variety of analytical service projects, the group employs numerous instrumental analysis techniques including gas and liquid chromatography, mass spectrometry, infrared spectroscopy, emission spectroscopy and capillary electrophoresis. Classical wet chemistry techniques including titrimetry, gravimetry and calorimetry are also used routinely. Paper Physical Analysis Laboratory (Dr. Roman Popil) Changing paper industry market expectations often lead to increased use of recycle fiber content, increased use of pigment fillers and other additives. Although such strategies may meet product specifications, end-use field performance characteristics such as printability, longevity, convertability, gluability may become compromised. Resolution of the cause of these problems from a skilled informative analysis of failed specimens is where IPST Analytical and Testing Service provide an invaluable resource. IPST has an established legacy of developing many of the standard testing protocols in use today in the pulp and paper industry. IPST led the implementation of ultrasonic measurements to paper now popularly known as “TSO”. Research programs in corrugated packaging have developed specialized testing equipment and methods that are not available elsewhere. Novel alternative methods continue to be explored to address current newsworthy issues such as fold cracking, “flushability” of non-wovens, percent recycled content of products, tissue/towel softness water absorption and performance characteristics, replacement of ring crush (RCT) with short span compression (SCT), and reduction of variability in testing methods.

Pulping, Bleaching and Chemical Recovery Laboratory (Dr. Rallming Yang, Dr. Scott Sinquefield, Steve Lien) The Pulping, Bleaching and Chemical Recovery group at IPST has well equipped laboratories for testing and analysis of raw materials and pulps. Standard methods for chip analysis and most pulp quality tests are available. In 2013, we extended our pulping lab to include biomass pretreatment capability by acquiring a modified kraft (MK) digester. It is a dual vessel system with computer-control heating. The digester system allows a maximum cooking pressure up to 320 psi and permits sampling while cooking is in progress. This capability allows the MK digester system to simulate a variety of biorefining pretreatment protocols and modern cooking technologies used in Kraft pulp mills. A 12" single disk Sprout-Waldron refiner can be used to prepare linerboard kraft when it is combined with the MK digester. It is also capable of producing other forms of high-yield pulps. Other special capabilities include a computer-controlled handsheet press with heated platens, a corona discharge instrument for surface modification of paper sheets, and a 50-liter Pfaudler reactor for acid treatment of biomass. Raw materials for pulping studies can be prepared with a Carthage chipper and RaderT or ChipClassT chip screens. Several pulping systems are available including a multi-unit mini-digester and a digester system consisting of 4 cooking vessels and a liquor vessel for simulation of new batch and any other modified kraft cooking technologies. Our 15-liter pulper can be used for repulping study of various recycled papers. Simulations of most pulping and bleaching processes can also be conducted to enable informed decisions about mill operations. Almost all bleaching technologies can be performed in our lab in high-shear mixers. Pulp processing capabilities include laboratory screens, Valley Beater, PFI mill, and handsheet-making. In the chemical recovery area, a bench-top evaporator is used to concentrate weak black liquor and determine when soluble scale precipitates. After crystallization, filtered samples of the crystals can be collected for chemical analysis and determination of the crystal species. This information can help diagnose scaling problems in multiple effect evaporators. During an evaporation run, we monitor the particle size distribution of the precipitates and the boiling point rise. We also have the capability to measure liquor viscosity over a range of solids and temperatures. For thermochemistry work we have both a Laminar Entrained-Flow Reactor (LEFR), and a Pressurized Entrained-Flow Reactor (PEFR). These types of reactors create highly controlled conditions of temperature, pressure, residence time, and gas composition for the study of combustion, gasification, and pyrolysis. They are ideal for both fundamental chemistry and kinetic studies on a variety of dry granular fuels such as dried black liquor, forest biofuels, agricultural biofuels, coal, dried sludge, etc. The ash/char particles, gases, condensation aerosols, and tar fractions can all be collected separately for off-line analysis. In

addition to the entrained reactors, a thermo-gravimetric analyzer (TGA) is also available to study fuels at lower heating rates. Corrosion and Materials Chemistry Laboratory (Professor Preet Singh/ Jamshad Mahmood) Reliable performance of materials is very important for any industrial process, and especially for manufacturing high quality products in any industry, including the chemical process and pulp & paper industries. Material selection is generally based on the required material properties, low initial capital investment, and minimum maintenance. Changes in the process parameters to improve products can often lead to higher corrosion susceptibilities of the plant materials. Corrosion science and engineering research includes understanding the basic mechanisms involved in material degradation in given environments and using that knowledge to develop a mitigation strategy against environment-induced failures.
Research activities of the Corrosion and Materials Chemistry Research Laboratory (CMCRL) at the School of Materials Science and Engineering and the Institute of Paper Science and Technology at the Georgia Institute of Technology are focused on corrosion, stress corrosion cracking, high-temperature oxidation, and other forms of environmentally induced degradation of metallic materials. Analytical and characterization tools needed for corrosion research are available either in our laboratory or in the School of Materials Science and Engineering at Georgia Tech.

Other Research Laboratory Capabilities
Green Bioprocessing Laboratory (Professor Art Ragauskas) Our research program focuses on green chemistry of biopolymers including cellulose, hemicellulose, and lignin. Through the use of green chemistry, biotechnology, and cold plasma, our research group is looking at new ways to synthesize novel biomaterials, biocomposites, and biofuels from nature's renewable biopolymers. An exciting aspect of this research is the development of new nanocellulose- and hemicellulose-based materials. Such innovative research approaches allow researchers to synthesize new biomaterials that could be used for smart-polymers, controlled release, and enhanced barrier properties for health care, packaging, and security applications. Our research program is also renowned for its fundamental oxidative chemistry and structural elucidation of polysaccharides and lignin. Students involved in these studies utilize our state-of-the-art NMR and MS facilities. An active field of research that presents vast opportunities is the use of cellulose to develop new biocomposites. An example of this is the biocomposite being prepared from polysaccharides and polylactic acid, a unique product that exhibits far greater performance than either material alone. This research involves a great deal of physical chemistry at the surface of differing materials including surface grafting reactions, polymer chemistry, and surface analysis employing ESCA, AFM, and SEM. Another area of carbohydrate research lies in the creation of biofuels, which are being developed through the depolymerization of biomass. The substitution of imported hydrocarbons with bio-based fuels and chemicals offers a tremendous opportunity to develop new renewable green chemistry processes that exhibit substantially improved environmental performance properties and net reductions in CO2 emissions. Currently, we are examining unique catalytic chemistries and biotechnologies (i.e., laccase, peroxidase, endoglucanase) in ionic liquids that will convert lignocellulosics into valuable biofuels. Student research is conducted in a multidisciplinary environment with several projects involving collaborative efforts with other groups on campus, nationally, and internationally.

Surface Characterization Testing Laboratory (Professor Yulin Deng) The group’s research interests are nanomaterial synthesis and self-assembling biofuel and biomass-based materials, colloid and surface science and engineering, polymer synthesis, and papermaking and paper recycling. In nanomaterial synthesis and characterization, one-dimensional nanomaterials, including ZnO, TiO2, Mg(OH)2, Au, polyaniline, and two-dimensional nanomaterials with ordered patterns have been some of the research projects. The unique applications of such one- and two- dimensional nanomaterials as a sensor, solar cell and super-capacitors have been studied. The one-dimensional nanomaterials synthesized in our lab have also been used as reinforcement materials in polymer nanocomposite material. Cellulose nanowhiskers, which are biodegradable one-dimensional materials, have been used as reinforcement nanomaterials in our high-strength fiber preparation. Hollow-structure inorganic materials, such as TiO2, and polymer materials such as poly(iso-propyl acrylamide) have been synthesized. These unique nanomaterials can be used in many applications including for example drug delivery and solar cells. Nanocomposites such as polymer/nanoclay hybrids are engineering materials that have great potential in many industries. Recent research indicated that exfoliated nanoclay could be encapsulated in polymer latices. The water-based polymer-nanoclay suspension is a great candidate for painting and paper coating. In biofuel research, the group has been developing a novel pretreatment of lignocellulose for biofuel production. Catalytic depolymerization of lignin, including chemical and photocatalytic conversion of lignin into fuel, is one of the current active research projects within the research group.
