Abstract
Natural dye molecules are used as light harvesting material in photovoltaic cells. Here a
solid-state absorber was used as a sensitizer in conjunction with the Opuntia Stricta fruit dye.
Nanostructured Titanium dioxide (TiO2) photo anode was prepared by doctor bladding technique
on chemically sprayed Indium Tin Oxide (ITO) glass substrates. Natural dyes (Opuntia Stricta
fruit) have been used for the fabrication of dye sensitized solar cells (DSSC) with a novel route.
The surface morphology was studies using X-ray diffraction (XRD), Scanning electron
microscopy (SEM). The optical studies were done by UV - visible absorption spectroscopy. The
solar cell efficiency has been calculated and is found to be 0.59% to 0.92% with different dye
conditions.
Keywords: Opuntia Stricta fruit dye, DSSC, Titanium dioxide, Doctor Bladding.

Abstract
High quality single crystal of efficient novel nonlinear optical (NLO) 2-(2-Bromoethyl)-
1H-isoindole-1,3(2H)-dione crystal has been grown and its structure has been characterized by
Fourier Transform Infrared (4000-400 cm-1), Fourier Transform Raman (3500-50 cm-1) and
single-crystal X-ray diffraction techniques. The vibrational wavenumbers were computed using
Density Functional Theory (DFT) and are assigned with the help of potential energy distribution
(PED) method. The geometrical parameters of the title compound obtained from X-Ray
diffraction (XRD) studies are compared with the calculated (DFT) values using 6-31G(d,p) basis
set. Stability of the molecule, hyperconjugative interactions, charge delocalization and
intramolecular hydrogen bond has been analyzed by using natural bond orbital (NBO) analysis.
Electronic structures were discussed by Time Dependent Density Functional Theory (TD-DFT)
and the relocation of the electron density was determined. Nonlinear optical (NLO) properties
were also investigated. The Time dependent Density Functional Theory (TD-DFT) method has
been used to calculate energies, oscillator strengths of electronic singlet–singlet transitions and
the absorption wavelengths. The Higher occupied molecular orbital (HOMO) and The Lower
unoccupied molecular orbital (LUMO) analysis are used to determine the charge transfer within
the molecule. Comprehensive theoretical and experimental structural studies on the molecule
have been carried out by FT-IR, FT-Raman and Ultra Violet–visible spectrometry (UV-vis).
Key words: XRD, FTIR, FT-RAMAN, UV, NBO, NLO.

ABSTRACT
We have explored Vacuum evaporated CdS as a heteropartner for PbS QD solar cells for
comparison with ZnO and nanostructure TiO2. CdS is a non-stoichiometric n-type semiconductor
with direct band gap energy of 2.42 eV. Our investigations of this device design show an
optimized double layer CdS film thickness of 70 and 65 nm and an optimized PbS QD diameter
of ∼2.85 nm, corresponding to a bandgap energy of ∼1.6 eV. Under simulated AM1.5 G
illumination, we attain short circuit current as high as 12 mA-cm-2
, an open circuit voltage of
0.65 V and efficiency as high as 3%. To our knowledge, no previous report has been made on
photovoltaic devices based on Vacuum evaporated CdS as a window layer for a colloidal
PbS QD thin film absorber layer.

Abstract
The tight focusing properties of azimuthally polarized Hollow Gaussian Beam (HGB)
with on-axis spiral optical vortex focused through a dielectric interface is investigated
theoretically by vector diffraction theory. It is observed that the presence of dielectric interface
generates focal shift and proper tuning of phase parameter leads to focal shift along optical axis
towards the aperture and makes the focal segment exactly at the geometrical focus. In addition,
focal shift direction can also be adjusted by changing direction of phase parameter.

Abstract:
Among the semiconducting, wide band gap, transparent conducting oxides, ZnO stands
as a prominent candidate for efficient window layers in solar energy conversion devices, which
requires low resistivity and high transmittance. The most popular, cost effective method for ZnO
preparation is chemical bath method, which lacks from quality of films. For obtaining
homogeneous, crystalline, quality ZnO thin films for device fabrication, here we adopted a two-
stage technique.Zn films are deposited onto glass substrates bythermal evaporationin
vacuum~10-5 mbar in a metallic chamber. In the second stage, the Zn filmsare subjected to
thermal oxidation by‘air annealing’uptoa temperature of 350⁰C, to form very transparent ZnO
films.Structural analysis (X-ray diffraction),indicatedthat the ZnO thin films so produced possess
nanosized (~ 22nm)polycrystalline structure with preferred orientation along (002). SEM images
indicate formation of nano rods randomly oriented on the substrate surface. The optical
parameters like transmittance, optical bandgap (3.23eV),photoresponse and spectral responseof
the as-prepared ZnO films are obtained through optical absorbance and photosensitivity
measurements.A resistivity ~ 10 Ωm is shown by the as-prepared ZnO films. The temperature
dependence of electrical conductivity indicate an activation energy of0.651eV, indicating a
defect state. High transmittance and better Photoresponse reveals the suitability of the as-
prepared ZnO films in the field of optoelectronic applications.
Keywords.TCO; ZnO; optical bandgap; electrical conductivity.

Abstract
Conductive polyaniline (PANI) is nowadays in the forefront because of its very
good electrical conductivity combined with other beneficial properties such as light weight, good
attrition of all type substrates low cost and simple synthesis and preparation methods. Not only
PANI in the powder form, but also thin or thick film are widely investigated, because they can be
used in wide field of applications, like strain sensor, antistatic and anticorrosive coating of in the
field of conductive textiles to use the EMI shielding cloth productions. In this work deals with
the structural, Morphological and electrical properties of PANI coated cotton, polyester and
cotton blended polyester in textile fabric substrates. The conductive textile substrates were
prepared by in-situ chemical oxidative polymerization of aniline monomer and ammonium per
sulphate as oxidant. The structural and morphological features of the resultant fabrics were
analyzed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy
(SEM) studies and structural properties of XRD. The electrical conductivity was expressed as
both bulk and surface properties. The PANI-coated fabrics thus produced are suitable in
application of EMI shielding.
Keywords: Electrically conductive textile fabrics, Polyaniline synthesis, XRD, SEM,

Abstract:
To explain the anomalous transport properties of a low carrier density magnetic system
EuB6, theferromagnetic Kondo lattice model has been explored with the strong interaction
between charge carriers and local magnetic moments. The role of lattice degrees of freedom is
studied through the mean-field approximation. Judging from negligible isotope effect in EuB6,
the lattice effect is expected to be small, but thermal-conductivity measurement on EuB6 implies
non-negligible electron-phonon scattering near and below Tc. Although the electron-phonon
interaction is much weaker than the electron-magnon interaction, small lattice effect can change
the transport properties of the magnetic polaron appreciably.The resistivity peak near 15K is
thought to be from the magnetic polaron formation and the lattice effect helps it with enhancing
the localization tendency. Below Tc, there appear overlaps between polarons and the resistivity
decreases abruptly. The influences of phonon and impurity sites play a crucial role in helping the
formation of the magnetic polaron near Tc and producing the resistivity peak and the metal to
insulator transition, which are consistent with experimental results.
Key Words: electron-phonon interaction, ferromagnetic Kondo lattice model, magnetic polaron.

Abstract
Tin Sulphide (SnS) thin film based Cu/SnS/ZnO solar cell layers were deposited by
thermally vacuum evaporated on flexible substrates. While the Zinc oxide and TCO thicknesses
were kept constant at 100nm, Copper layer thicknesses of 0.25µm and SnS of 3 µm were used to
obtain the metallic precursors. X-ray diffraction studies reveal polycrystalline films with
preferential orientation. The films with lowest oxide layer thickness exhibited binary metal alloy
contents, which disappears with higher SnS precursor layer thickness. The surface morphology
and elemental composition of SnS thin films was determined from scanning electron microscopy
and energy dispersive spectroscopy analysis respectively. UV-Vis absorption studies reveals that
SnS thin film has band gap (1.30 eV) and large absorption coefficient value, it was optimal for
photovoltaic applications. The manipulations in the parameters of the layers result into increase
of conversion efficiency (η) value of 15.92 % - 16.41 %.

ABSTRACT
ZnO is a wurtzite-type semiconductor with band gap of 3.37 eV and excitation
binding energy (60 meV). The direct band gap and a large exciton binding energy are useful for
applications in photo detectors, ultra-violet nano-laser, and nano generation. Samples of ZnO,
Zn0.5Mg0.5O and MgO were prepared by co-precipitation method. X-ray diffraction (XRD)
pattern infers that the sample of ZnO is in single-phase wurtzite structure (hexagonal phase,
space group P63mc), MgO crystallizes in cubic Fd3m space group and Zn0.5Mg0.5O represents
mixed nature of ZnO and MgO lattices. Similar features were observed from Raman
spectroscopy. The energy band gaps estimated from UV-Vis spectroscopy are found to be 4.21
and 3.42 eV for ZnO and Zn0.5Mg0.5O samples respectively.

Abstract
Doping with selective elements offers an effective method to enhance and control the
electrical and optical properties of ZnO nanostructures, which is crucial for its practical
application. Sn doped ZnO nanoparticles with different dopant concentrations were prepared by
simple precipitation method. The Sn doped ZnO nanoparticles have got the particle size in the
range of 20nm to 60 nm. As the Sn concentration increases the agglomeration takes place and
absorption edge slightly shifts towards the longer wavelength region which may be attributed to
the decrease in band gap. The Sn doped nano particles have changed the optical properties
effectively which was confirmed by PL spectroscopy. In this paper, we report synthesis,
characterization and optical properties of Sn doped ZnO nanopaerticles by precipitation method
and its characterization by using XRD, SEM, EDAX and UV-Vis and PL spectroscopic methods.
Keywords: precipitation method, nanostructures, EDAX, Sn, ZnO, PL spectroscopy.

prepared by oxidative polymerization of thiophene monomer with iron (III) chloride as a catalyst
in the presence of ZnO nano particles. After polymerisation, polythiophene in oxidized form was
reduced by the extraction in methanol solution. The composite material was dissolved into M-
Pyrol, N-Methyl-2- pyrrlidinone (NMP) to produce a composite precursor solution of PTh-ZnO
Nanocomposites. The composites solutions were deposited onto glass substrates using a spin-
coating technique to fabricate PTh-ZnO thin film. Nanocomposites thin film were characterised
by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM)
studies and structural properties of XRD analysis.

ABSTRACT
Colloidal PbS: In and CdS quantum dots (QDs) are sequentially assembled onto a
nanocrystalline TiO2 film to prepare a PbS: In/CdS co-sensitized photo electrode for QD
sensitized solar cells (QDSCs). In the cascade structure of the electrode, the reorganization of
energy levels between PbS and TiO2 forms a stepwise structure of band-edge levels which is
advantageous to the electron injection into TiO2. Energy conversion efficiency of 3.07% is
achieved with the doped electrode, under the illumination of one sun (AM1.5, 100mWcm-2
).
Besides, a remarkable short circuit current density (up to 27mA⋅cm−2

annealed at different temperatures. The as-prepared TiO2 are amorphous, and then it transformed
into anatase phase on annealing at 550°C, and rutile phase on annealing at 950°C. The X-ray
diffraction results showed that TiO2 wafer-like structure with grain size in the range of 30 to 45
nm for anatase phase and 65 to 80 nm for rutile phase have been obtained. SEM images show the
formation of TiO2 nanoparticles. Optical absorption studies reveal that the absorption edge shifts
towards longer wavelength (red shift) with increase of annealing temperature.

Abstract
Selenium nanoparticles were prepared by chemical method. The x-ray diffraction studies
indicated the formation of Se with hexagonal phase and no secondary phase was observed. The
composition analysis results show that Se is present in the sample. TEM images reveal that Se
nanoparticles size ranging from 30-50 nm. The present study was conducted to determine the
effect of prepared selenium nanoparticles on the growth performance of broiler chickens. Thirty
numbers of a day old Vencobb broiler chicks were wing banded, weighed and randomly
allotted to three groups with ten chicks in each group. Their weight gain was taken for six
consecutive weeks to observe the effect of dietary selenium nanoparticles over growth utilization
of birds. Three different groups, T1 control standard diet, T2 Standard diet + Sodium selenium
0.3mg/Kg diet and T3 Standard diet + Selenium nanoparticles 0.3mg/Kg diet respectively. The
percent weight gain was highest in T3 group as compare to T1 and T2 which was supplemented
0.3 mg Se/kg of feed. Therefore it was concluded that supplementation of selenium nanoparticles
0.3 mg/kg diet of poultry enhances the growth rate in the broiler birds.

Abstract
Present paper deals a comprehensive analysis of variation in excitonic charge, Bohr
radius, photo emission and optical absorption band gap as a function of size of CdSe quantum
dot. In quantum dot (QD) Bohr radius is of the same order of magnitude as the diameter of the
QD giving rise to quantum confinement of the exciton which results in discrete energy level
rather than the continuous bands of bulk semiconductor crystals. The band gap may be easily
tuned by simply changing the diameter of the QD as long as the diameter is smaller than the
Bohr radius. Excitonic binding energy as a degree of size of QD is also calculated which further
relates with the difference in PE electronic and OA optical band gaps. It is also shown that with
increase in size of CdSe QD, the excitonic binding energy decreases which consequently
increases differences in two band gaps. Our results are very well comparable with the established
results. Explanation for the origin of the unusual optical properties of CdSe QD has been also
discussed.

ABSTRACT
Transparent conductive oxides (TCOs) are impurity doped metal oxides, such as
indium oxide (In2O3), zinc oxide (ZnO), and tin oxide (SnO2), which exhibit excellent properties
of controllable low resistivity and high transparency in the visible region. A method for the
synthesis of high quality indium-doped zinc oxide (In-doped ZnO) nanocrystals were developed
using a one-step ester elimination reaction based on alcoholysis of metal carboxylate salts. The
resulting nearly monodisperse nanocrystals are well-crystallized with typically crystal structure
identical to that of wurtzite type of ZnO. Structural, optical, and elemental analyses on the
products indicate the incorporation of indium into the host ZnO lattices. The individual
nanocrystals with cubic structures were observed in the 5% In–ZnO reaction, due to the
relatively high reactivity of indium precursors. The reactions can be monitored by Fourier
transform infrared spectroscopy (FTIR) and UV–Visible absorption spectra (UV–Vis), making
them ideal for investigating the processes. Our results may provide insights for the growth of
doped oxide nanocrystals.

ABSTRACT
Results regarding structural properties, optical properties and photovoltaic characteristics
of Cu2ZnSnS4 (CZTS) thin films prepared by sequential deposition of Cu, ZnS and Sn thin films
by vacuum evaporation are compared with those obtained with CZTS films grown by sequential
deposition of Cu2SnS3 (CTS) and ZnS thin films by CBD Process. X-ray diffraction analysis
(XRD) which is mostly used for phase identification cannot clearly distinguish the formation of
secondary phases such as Cu2SnS3, since both compounds have similar diffraction patterns;
therefore, Raman scattering analysis was used to distinguish these phases. Further, the
photovoltaic characteristics short-circuit current density (Isc), open-circuit voltage (Voc),a fill
factor(FF) and efficiency are studied under AM 1.5(100mW/Cm2) illumination.

Abstract:
In the present study, we report on the synthesis of Fe3O4 (magnetite) nanoparticlees by
Hydrothermal method. In this process we used Iron chloride (FeCl2.4H2O) and NH4 (15ml)
Solution as a precursor for the preparation of Fe3O4 nanoparticles. In the Hydrothermal process,
the Fe3O4 nanoparticles were synthesized at low temperature (1600C). The synthesized
nanoparticles were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray
Diffraction (XRD), Scanning Electron Microscopy (SEM). From the XRD measurements, we
found that the prepared magnetite nanoparticles are cubic inverse spinel structure and with
average size of 15-18 nm.

ABSTRACT
Tin is a high value metal and its compounds are also used in many modern and
conventional industrial processes such as lithography, alloys for electronic circuits, reaction
catalysis, anti corrosion coating agent, dopant for electrode of modern solar cells. Presence of tin
in water bodies causes enormous environmental concern due to its acute toxicity to living beings.
We demonstrate a simple and zero emission process for extraction of tin ions from aqueous
solution using dithiocarbamate-based copolymer and its single step quantitative recovery and
transformation into SnS nanoparticles. The polymer shows high metal extraction capacity, 1.06 g
SnCl2 per gram of polymer. The polymer metal composite and SnS nanoparticles are analyzed
using SEM, FTIR, XRD spectroscopy techniques. The FTIR shows formation of Sn-S bonding in
the polymer metal composite. This study has implication for cost effective and green approach
for purification of water and waste management. We used the potential of the dithiocarbamate-
based copolymer to extract tin chloride through chemical bonding, thereby transforming it into
tin sulfide nanoparticles.

ABSTRACT
Quantum dots (QDs) have attracted much attention for use in photovoltaic
applications because of their potential for overcoming the limits of conventional single-junction
devices. One problem associated with solar cells using QDs is that the open-circuit voltage (Voc)
always decreases with the addition of QDs with respect to the reference cell without QDs.
Different size SnS quantum dots are prepared by SILAR method. Size of the particles is varied
from 2.1 to 16 nm by varying the deposition cycles from 25 to 150. solar cells are fabricated with
these quantum dots. Cu2S coated ITO is used as counter electrode instead of the conventional
platinum electrode and Na2S as electrolyte. Cu2S acts as a good catalyst for the polysulfide
electrolyte. On comparing with a cell having platinum counter electrode and iodine based
electrolyte, Cu2S -polysulfide combination found to improve both the short circuit current and
fill factor of the solar cell.

ABSTRACT
Chalcogenide-based materials have been attractive candidates for future thin film
photovoltaic applications due to their advantages of high efficiency, long-term stability and
diversity of fabrication methods. CZTS is promising for low-cost thin-film solar cells due to its
suitable bandgap energy of 1.4-1.5eV and the large absorption coefficient over 104
cm-1
.
Nanocrystalline Cu2ZnSnS4 (CZTS) powder was synthesized by a hydrothermal process, using
thiourea as sulfur precursor. The powder was qualitatively analyzed using X-ray to identify the
phase, and the size of the particles was determined using transmission electron microscopy
(TEM). Raman peak at 337.5 cm−1
confirms the formation of pure CZTS particles. The powder
was also synthesized solvothermally using ethylenediamine as solvent. The hydrothermally
synthesized powder indicated the presence of the kesterite phase Cu2ZnSnS4 and particle size of
about 4-5 nm. This environmentally green synthesis by hydrothermal route can produce gram
scale synthesis of material with a chemical yield in excess of ∼ 90%. UV Vis absorption spectra
measurements indicated the band gap of as-synthesized CZTS nanoparticles to be 1.7 eV, which
is near the optimum value for photovoltaic solar cell, showing its possible use in Photovoltaics.

ABSTRACT
CZTS nanocrystal films as counter electrodes in photoelectrochemical solar cells
plays an important role in transferring electrons from the external circuit back to the redox
electrolyte for catalytic reduction of the redox electrolyte, CZTS NC film was prepared by drop
coating method. Wurtzite and kesterite Cu2ZnSnS4 (CZTS) nanocrystals were employed as
counter electrode (CE) materials for dye sensitized solar cells (DSSCs). Compared to kesterite
CZTS, the wurtzite CZTS exhibited higher electro catalytic activity for catalyzing reduction of
iodide electrolyte and better conductivity. Accordingly, the DSSC with wurtzite CZTS CE
generated higher power conversion efficiency (3.45%) than that of Pt (3.13%) and kesterite
CZTS (2.49%) CEs. The excellent performance of the wurtzite CZTS CE paves a new pathway
for preparing cheap and highly efficient CEs for DSSCs.

Abstract
In this study, geometrical optimization, spectroscopic analysis, electronic structure and
nuclear magnetic resonance studies of Vildagliptin were investigated by utilizing HF and
DFT/B3LYP with 6-31G (d, p) as basis set. The Fourier transform infrared (FT-IR) and FT-
Raman spectra of Vildagliptin were recorded in the region 4000–400 cm-1 and 3500–50 cm-1,
respectively. Complete vibrational assignments, analysis and correlation of the fundamental
modes for the title compound were carried out. UV–Visible spectrum of the compound that
dissolved in ethanol were recorded in the region 200–800 nm and the electronic properties
HOMO and LUMO energies were measured by TD-DFT approach. The calculated HOMO and
LUMO energies show that charge transfer occurs within the molecule. The molecular stability
and bond strength have been investigated by applying the Natural Bond Orbital (NBO) analysis.
The 1H and 13C nuclear magnetic resonance (NMR) chemical shifts of Vildagliptin were
calculated using the GIAO method in ethanol solution and compared with the measured
experimental data. All the calculated results were compared with the available experimental data
of the title molecules.

Abstract
Present work deals with a detailed characterisation of ceria nano particles obtained from
aqueous cerium nitrate in presence of ammonia and CTAB. The characterisation tools include
XRD, thermal studies, N2 adsorption analysis, SEM, TEM, DRUV spectra, and XPS. Electron
Microscopy studies revealed the particles to be of size ~7 nm. XRD study identified cubic CeO2
belonging to Fm3m space group. The UV spectrum of ceria particles was blue-shifted with
respect to the bulk material indicating quantum-confinement, which is an expected phenomenon
of particles in nano regime. Small particle size of the oxide led to high oxygen vacancy and
associated higher concentration of Ce3+, rendering the system suitable for catalytic applications.

The present work examines the dielectric property of ceria nanostructures of two different
morphologies. Morphological characteristics and crystalline nature of the structures were
analysed by electron microscopic analysis and powder X-ray diffraction analysis. Nanosized
particles of cubic and spherical morphologies were obtained with average particle sizes 16 nm
and 20 nm respectively. Dielectric studies showed a more dielectric dispersion of the materials
at low frequency region that attains a temperature independent constant value at high
frequencies. The a.c. electrical conductivity of the systems was also measured from the
permittivity values and dielectric loss factor.

ABSTRACT
Numerical simulation is a powerful tool and many parameters can be varied to model
the observed phenomenon. It can also offer a physical explanation of the observed phenomenon
since internal parameters such as the recombination rate and the free carrier densities can be
calculated. In this work we have used Silvaco Atlas software on the design and the study of a
CIGS solar cell. 2 D Silvaco Atlas software is used for the study of a CIGS thin film solar cell in
the configuration: ZnO (200 nm)/n-type CdS (50 nm)/ p-type CIGS (350 nm)/Mo. The cell
performance is evaluated by implementing the defects created at the grain boundaries of the
polycrystalline CdS and CIGS material and at the interface CdS/CIGS. The J-V characteristics
and the external quantum efficiency EQE are simulated under AM 1.5 illumination. The
conversion efficiency of 20.35% is reached and the other characteristic parameters are simulated:
the short circuit current density Jsc equals 35.62 mA/cm2, the open circuit voltage Voc is of 0.69
V and the fill factor FF is of 82.7 %. The calculated external parameters of the solar cell are in
good agreement with the measured characteristics. The simulation results also showed that the
rise of the CdS thickness decreases all output parameters and the external quantum efficiency
while the rise of the CIGS thickness improves all photovoltaic parameters and the external
quantum efficiency. The highest efficiency of 21.08 % is reached for the CIGS thickness of
5 μm.

ABSTRACT
Al-doped ZnO (AZO) thin films were deposited on indium tin oxide substrates by
vacuum evaporation method. The influence of the doping level of the ZnO: Al films was
investigated. The results of the X-ray diffraction and scanning electron microscopy analysis
revealed that the structural properties of the AZO films were found polycrystalline with a
hexagonal wurtzite-type structure along the (002) plane. The grain size of the AZO films was
observed as approximately 6-8 nm in the film doping with 4 mol% ZnO: Al concentration. The
thin films also exhibited an optical transmittance as high as 90 % in the wavelength range of
100–1,000 nm. The optical band gap increased from 3.33 to 3.45 eV. Based on the Hall studies,
the lowest resistivity was observed in the film doping with 3 mol% ZnO: Al concentration. The
sheet resistant, carrier concentration and Hall mobility values were found as 10.78 Ω/ square,
9.03 9 1018 cm-3
and 22.01 cm2 /v s, respectively, which showed improvements in the properties
of AZO thin films. The ZnO: Al thin films were used as a buffer layer in thin-film solar cells with
the structure of soda-lime glass/Mo/Cu2ZnSnS4/ZnS/ ZnO/Al grid. The best solar cell efficiency
was 2.3 % with VOC of 0.430 V, JSC of 8.24 mA cm-2 and FF of 68.1 %.

ABSTRACT
In this paper, we prepared CdS/CdSe/ZnS co-sensitizer on mesoporous TiO2 surfaces
with different SILAR cycles. The optical properties of the photo anodes and the photovoltaic
performance of the corresponding solar cells were investigated. The photovoltaic performance
of quantum dot-sensitized solar cells (QDSSCs) based on mesoscopic TiO2 spheres. A series of
CdS/CdSe/ZnS co-sensitized TiO2 photo anodes for QDSSCs were prepared by successive ionic
layer adsorption and reaction (SILAR) processes. The growth of CdS, CdSe and ZnS layers were
monitored by taking UV-Visible absorption spectra and the SILAR cycles of CdS, CdSe and ZnS
show different impact on the performance of QDSSCs. With the deposition times of CdS, CdSe
changing (from 1 to 5 cycles), and the parameters of the device is changed. In addition to
determine the quality of QDSSCs, we used modern physical methods to calculate the
dynamic resistance values as RS, RSH, Rd, RD. The effect of SILAR cycles on the dynamic
resistance was discussed detail.

ABSTRACT
The objective of the present study was to formulate surface solid dispersions (SSD) of
simvastatin to improve the aqueous solubility and dissolution rate to facilitate faster onset of
action .The solubility of the poorly soluble drugs can be improved by various techniques such as
micronization, solubilization, salt formation, complexation with polymers, change in physical
form, use of prodrugs and drug derivatization, pH alteration, addition of surfactants , and others.
Among the various approaches, the solid- dispersion technique has often proved to be the most
successful in improving the dissolution and bioavailability of poorly soluble, active
pharmaceutical ingredients because it is simple, economical, and advantageous. Simvastatin
(SIM), a crystalline compound, is practically insoluble in water and hence poorly absorbed from
the GI tract , It is a potent and specific inhibitor of 3-hydroxy-3- methyl-glutaryl coenzyme A
(HMG CoA) reductase , which catalyzes the reduction of HMG CoA to mevalonate. Thus,
simvastatin arrests a key step for cholesterol biosynthesis in the liver and is widely used in the
treatment of hypercholesterolemia and dyslipidemia as an adjunct to diet. After oral
administration, Simvastatin is metabolized to its β-dihydroxy acid form (simvastatin acid) by the
cytochrome-3A system in the liver, where it inhibits the rate-limiting step in cholesterol
biosynthesis. This leads to up-regulation of low-density lipoprotein (LDL) receptors and an
increase in catabolism of LDL cholesterol. Being a BCS Class II drug, it often shows dissolution
rate-limited oral absorption and high variability in pharmacological effects. Therefore,
improvement in its solubility and dissolution rate may lead to enhancement in bioavailability . In
the present study, SSDs of simvastatin were prepared by physical mixture, kneading method and
Nanoparticle is prepared using solvent evoporation method. The nano based simvastatin were
characterized by differential scanning calorimetry (DSC), powder x-ray diffractometry (PXRD),
scanning electron microscopy (SEM), and infrared spectroscopy (IR).
KEY WORDS : Simvastatin, asafoetida, oral bioavailability, solid dispersion, HMG CoA.

Abstract
Poor water solubility is the major drawback for the various types of drugs and many
approaches have been introduced for the solubility enhancement of such drugs. Solid dispersions
have been known to be one amongst the recent means of improving the dissolution rate by
enhancement of solubility, and hence the bioavailability of poorly water soluble drugs. Solid
dispersion is a very useful method for pharmaceutical point of view because of its capability to
solve the solubility problems by using solid dispersion method. The present work was to
investigate the use of natural polymers for the formation of solid dispersion of Rosuvastatin
calcium nanoparticles. It provides special features including enhancement of solubility. In this
work desolvation technique was used to prepare nanoparticles. The behaviors of Rosuvastatin
calcium with natural polymer were characterized by FTIR, DSC, and SEM.
Key words: solid dispersion, solubility enhancement, natural polymer, nanoparticle.

ABSTRACT
Thinfilm paper supercapacitors are based on paper electrodes sandwiching an
integrated solid electrolyte and separator layer. A typical finished device with total weight of 0.3
gm exhibits a planar capacitance of approximately 87 µF/cm2 and a specific capacitance
estimated to be 100 F/gm. The developed paper supercapacitor is an improvement over some of
the state-of-art paper supercapacitors reported till date, which show similar specific capacitance
but have more mass than our device. The low total weight of our finished device arises from a
new combination of materials. This device is based on modifying the surface of a commercially
available carbon micro-fiber paper. An important consequence of the surface modification
processes is the incorporation of nano-structured active material and the consequent enhanced
surface area of the carbon micro-fiber paper. This contributes directly to the electrical behavior
of the device. The importance of the surface modification processes is underscored by the
capacitance characteristics of the supercapacitor which clearly show the influence of both silver
nanoparticles and carbon nanotubes as active materials.

Abstract
Nanotechnology will affect our lives tremendously over the next decade in very
different fields, including medicine and pharmacy. A major hurdle in pharmaceutical
formulation is water insolubility of most of drugs affecting their stability and bioavailability.
However, a new solution to poorly water soluble drug candidates is now available, i.e.
nanonisation that leads to much more soluble, more biologically available, and safer dosage form
of poorly soluble and poorly bioavailable drugs. Transfer of materials into the nanodimension
changes their physical properties which were used in pharmaceutics to develop a new innovative
formulation principle for poorly soluble drugs. Rosuvastatin Calcium (RST), poorly water
soluble Transfer of materials into the nano dimension changes their physical properties which
were used in pharmaceutics to develop a new innovative formulation principle for poorly soluble
drugs. RST is crystalline nature so it reduces its aqueous solubility and finally that results in an
oral bioavailability of 20%. Thus, the objective of this study was to improve the solubility and
dissolution rate of RST. The purpose of this research is to prepare solid dispersion of
Rosuvastatin calcium using sugar to increase the solubility. Solid dispersion of drug with sugar
was prepared by kneading method and nanoparticles by solvent evaporation method. The
prepared solid dispersions were characterized by DSC, FTIR, and SEM.

ABSTRACT
Zinc Sulfide thin films (ZnS) have been synthesized by chemical bath deposition
technique. The prepared samples were characterized by X-ray diffraction (XRD), Scanning
electron microscope (SEM), and UV-vis studies. XRD pattern of the prepared sample shows
preferential orientation along (002) crystallographic plane and can be indexed to hexagonal
wurtzite structure. Also XRD confirmed that the ZnS are polycrystalline in nature and no
additional peaks were present showing the formation of pure ZnS nanoparticles (ZnS). The
UV-Vis spectra showed absorbance peaks in the 300-800nm region. Optical transmittance
spectra gives excellent transmittance (>85%) and a sharp cut off edge at 385nm. From the
spectra, direct band gap of ZnS is determined which is 3.37eV at room temperature that makes
ZnS useful for optoelectronic devices such as solar cell, photonic crystals and photodiodes.

ABSTRACT
Enhancement of solubility, dissolution rate and bioavailability of drug is a very
challenging task in drug development, nearly 40% of the new chemical entities currently being
discovered are poorly water soluble drugs. The solubility and dissolution properties of drugs
play an important role in the process of formulation development. Among all newly discovered
chemical entities most of the drugs are lipophilic and fail to reach market due to their poor water
solubility. The main objective of work to enhance solubility of Simvastatin (SIM) by use of
Glucose and galactose as an hydrophilic carrier .Simvastatin is a BCS Class II drug having low
solubility (1.45 µg/mL) and therefore low oral bioavailability (5%). Simvastatin is chemically
(1S,3R,7S,8S,8aR) - 1,2,3,7,8,8a- Hexahydro-3,7- dimethyl-8-2-[(2R,4R)-tetrahydro-4-
hydroxy-6- oxo-2H-pyran-2-yl]ethyl-1-naphthyl-2,2-dimethyl butyrate is obtained from the
fermentation of Aspergillus terreus. This compound, acts as a highly potent and effective
cholesterol-lowering agent, is being used in the control of hypercholesterolemia. It exhibits a
very important hepatic first-pass metabolism, acting by blocking the 3-hydroxy-3-
methylglutaryl coenzyme A reductase (HMG-CoA), and thereby reducing the low-density
lipoproteins. Simvastatin is a potent inhibitor of HMG-CoA reductase, which is a rate limiting
enzyme in cholesterol bio-synthesis. Being a BCS Class II drug, it often shows dissolution rate-
limited oral absorption and high variability in pharmacological effects. Therefore, improvement
in its solubility and dissolution rate may lead to enhancement in bioavailability . In the present
study, SSDs of simvastatin were prepared by physical mixture, kneading method, solvent
evaporation method. Solid dispersions of simvastatin were characterized by differential scanning
calorimetry (DSC), powder x-ray diffractometry (PXRD), scanning electron microscopy (SEM),
and infrared spectroscopy (IR) and evaluated for drug content, saturation solubility, pH-
dependent solubility.
KEY WORDS: Simvastatin , solubility , absorption, solid dispersion

ABSTRACT
Solar cells based on nanoparticles have attracted intense attention in view of their
compatibility with the solution synthesis of materials, low-cost fabrication of devices, and large
area flexibility. A hybrid bulk-heterojunction (HBH) nanostructure providing a large contact area
and interpenetrated charge channels is favorable to an inorganic nanocrystal solar cell with high
performance. For this freshly appeared structure, here in this work, we have firstly explored the
influence of hybrid morphology on the photovoltaic performance of CdTe: CdSe bulk-
heterojunction solar cells with variation in CdSe nanoparticle morphology. Quantum dot (QD) or
nanotetrapod (NT)-shaped CdSe nanocrystals have been employed together with CdTe NTs to
construct different hybrid structures. The solar cells with the two different hybrid active layers
show obvious difference in photovoltaic performance. The hybrid structure with densely packed
and continuously interpenetrated two phases generates superior morphological and electrical
properties for more efficient inorganic bulk-heterojunction solar cells, which could be readily
realized in the NTs: QDs hybrid. This proved strategy is applicable and promising in designing
other highly efficient inorganic hybrid solar cells.

Abstract
Solubility is one of the most important physicochemical properties of drugs. If a
compound has a low aqueous solubility, it may be subjected to dissolution rate-limited or
solubility-limited absorption within the gastrointestinal tract. Atorvastatin calcium is used in the
treatment of primary hypercholesterolemia and dyslipidemia that is classified in class II (low
solubility and high permeability) according to the biopharmaceutical classification system. The
present study was designed to investigate the use of natural polymers in combination with β-
Cyclodextrin for the formation of inclusion complex of Atorvastatin calcium. Nanoparticle is an
interesting approach for poorly soluble drugs. It provides special features including enhancement
of solubility. In this work desolvation technique was used to prepare nanoparticles. The
