Pure and 3% rare earth ions (Nd3+ & Gd3+) doped ZnO samples were synthesized by sol-gel method, followed by annealing at temperature 450°C for 2hr. The samples were characterized by XRD, FTIR and UV-visible spectroscopy. XRD result confirmed single phase nature of all samples with crystalline structure. The average cr…
Hexaplana W-type barium ferrite of nominal composition BaZn1.5Co0.5Fe16O27 was prepared by a co-precipitation method. The structural and electrical properties were studied at different sintering temperatures. The average crystallite size was found to be in the range 46 ‒ 57 nm calculated by Scherrer formula, which mea…
Magnetic and dielectric properties of polycrystalline Z type hexaferrite Sr3Co2Fe24-xAlxO41 (x = 0, 0.45) have been studied. In the unsubstituted (x = 0) compound a single hump was observed in the magnetization curve at ~ 370 K while the substituted compound (x = 0.45) exhibits additional peaks at lower temperatures a…
Polycrystalline Bi2Te3-Sb2Te3 mixed crystals are synthesized by solid state reaction method. Structural characterizations are carried out using X-Ray diffraction (XRD). Thermal variation of resistivity data, measured down to 10K, shows that there is a transition from semiconducting to metallic behavior for 80% Sb cont…
Periodic mesoporous organosilicas containing biphenol bridging groups were modified post-synthesis to prepare aryl phosphate esters from the free diols.
Barium titanate (BaTiO 3 : BTO) nanoparticles (NPs) were synthesized by chlorine-free ambient condition sol (ACS) process using heat reflux at low temperature of 90°C. The size distribution and morphology of BTO NPs were investigated by varying the concentration of tetrabutylammonium hydroxide (TBAH). The crystalline…
Polythiophene incorporated carbon materials have sought huge attention due to various improved electrochemical properties including enhanced electrical conductivity. Our work includes the synthesis of polythiophene (PTP)-multi-wallcarbon nanotubes (MWCNTs) via in-situ polymerization method. The homogeneous distributio…

The mesomorphic properties of novel acenequinones reveals that a perpendicular packing motif is an important factor for determining mesophase stability.
In this work, Sn doped NiO nanoparticles were synthesized by co-precipitation route to explore the impact of doping on lattice structure, dielectric constant and magnetization. X-ray diffraction analysis confirmed cubic (Fd-3m) structure of Sn doped NiO. Average crystallite size decreases from 78.2 nm (Ni0.95Sn0.05O)…
The effect of hydrogen, accumulation and annealing of radiation defects on the physicomechanical properties of an austenitic Kh16N15M3T1 steel (16Cr15Ni3Mo1Ti) has been investigated upon low-temperature (77 K) neutron and electron irradiations. It has been shown that, when its concentration is about 300 at ppm, hydrog…
To study the effect of sulfonic acid group as substituent on the molecular structure of an organic compound copper Phthalocyanine, the optimized geometry, mulliken charges, energies and dipole momemts of copper phthalocyanine and copper phthalocyaninetetrasulfonic acid tetra sodium salt have been investigated using de…
Large single crystals of Sodium D-isoacsorbate monohydrate and Lithium L-ascorbate dehydrate were grown using solution growth technique. Dielectric constant and dielectric loss were monitored as a function of frequency at different temperatures. These are typically characterized by strong resonance peaks. The piezoele…

PyroSim software was used to establish the combustion behavior of polymers in the cone calorimeter test, the char yield, the effects of thermal conductivity and the specific heat capacity of the char layer on the combustion process of polymer were analyzed. The results show that, the heat release rate curves show a si…
The fabrication and characterization of electroluminescent ZnO:Zn(n$^{+}$)/Porous Silicon/Si(p) heterojunctions is presented. Highly conductive ZnO films (ZnO:Zn(n$^{+}$)) were produced by applying a temperature annealing at 400$^{\circ}$C by 5 min to the ZnO/Zn/ZnO arrange formed by DC sputtering, and the Porous Sili…
The time stability of solid oxide fuel cell (SOFC) was tested using all ceramic La 0.7 Sr 0.3 VO 3–δ -Ce 0.85 Sm 0.15 O 2–δ (SDC) perovskite material as an alternative anode and La 0.8 Sr 0.2 CoO 3−δ -SDC as a cathode. Both electrodes were prepared using infiltration method. The time stability measurements were carrie…
Sintering of powder mixtures is one of the widely used production methods of composite materials. The distribution of the reinforcement phases in these composites is a function of both initial powder structure and sintering conditions. Based on the recent literature and experimental results obtained by the authors, th…
Electronic structures and magnetic properties of multi-decker phthalocyanines were studied by theoretical calculation.
