We measured the Raman and the infrared phonon spectrum of SmFeAsO polycrystalline samples. We also performed density functional theory calculations within the pseudopotential approximation to obtain the structural and dynamical lattice properties of both the SmFeAsO and the prototype LaFeAsO compounds. The measured Ra…
This paper deals with partial discharge (PD) causing degradation of XLPE cable joint and interfacial phenomena of XLPE/EPR interface due to artificial defects such as metal particles, needle-like void and fiber soaked with water. We measured aging time dependence of phase-resolved PD (phi-q-n) patterns and PD statisti…
The structure of a high-pressure polymorph of glycine (the β ′-polymorph formed reversibly at 0.8 GPa from the β -polymorph) was determined from high-resolution X-ray powder diffraction data collected in situ in a diamond anvil cell at nine pressure points up to 2.6 GPa. X-ray powder diffraction study gave a structura…
Abstract Reduction rates of rhodium supported on alumina were investigated with in situ time‐resolved X‐ray absorption fine structure (XAFS). The catalytic sample was prepared with 0.5‐wt% rhodium on the alumina powder by a usual impregnation method. Two types of XAFS techniques were applied for the experiments: energ…
Porous superhydrophobic linear low-density polyethylene (LLDPE) surface was prepared by a simple method. Its water contact angle and sliding angle were 153±2° and 10°, respectively. After contamination, 99% of the contaminant particles were removed from the superhydrophobic LLDPE surface using artificial rain. The sup…
Dielectric relaxation and an electro-optical study of two ferroelectric liquid crystals having different spontaneous polarizations (Felix 16/100 and Felix 17/000) showing SmC* and SmA phases have been performed in the temperature range 30–80 ∘ C. The experimental data have been used to determine different relaxation p…
The authors report fabrication of aluminum monodoped ZnO (AlZnO) and aluminum-indium dual-doped ZnO (AlInZnO) nanorods arrays. Optical properties of AlZnO and AlInZnO nanorods are studied through temperature-dependent photoluminescence (PL) and PL excitation (PLE). Compared to AlInZnO nanorods, AlZnO nanorods possess…
Results on the characterization of photoluminescent CaCu 3 Ti 4 O 12 ‐based films, prepared from a sol–gel precursor and heat treated at 700°C, are reported for the first time. The samples showed two emission bands at 554 and 800 nm when excited with a 488 nm Ar‐ion laser. The photoluminescent emission measured at roo…
Diluted magnetic semiconducting ZnO:Co thin films with above room-temperature TC were prepared. Transmission electron microscopy and x-ray diffraction studies indicate the ZnO:Co thin films are free of secondary phases. The magnetization of the ZnO:Co thin films shows a free electron carrier concentration dependence,…
The protective effect of latex of Calotropis procera in Freund's Complete Adjuvant (FCA) induced monoarticular arthritis was evaluated in rats. Arthritis was induced by a single intra-articular injection of 0.1 mL of 0.1% FCA in the right ankle joint. The effect of dried latex (DL, 200 and 400 mg/kg) and its methanol…
Electric transport measurements of the charge-frustrated LuFe 2 O 4 , in which charge ordering (CO) and electronic ferroelectricity are found, reveal a strong nonlinear electric conduction upon application of electric fields in both single-crystalline and polycrystalline samples. The threshold electric fields ( E t )…
Silk fibroin (SF) is well known to be biocompatible, degradable, and nontoxic. In this study, SF was impregnated into a porous polyester graft (InterVascular external velour, InterVascular, Inc., La Ciotat, France), 8 mm in diameter. The SF-impregnated graft was investigated in vitro and in vivo to evaluate its potent…
Abstract Ring, Rotor and Air vortex spinning systems provide yarn with different structures and properties. Each system has its limitations and advantages in terms of technical feasibility and economic viability. 30's Ne, 100%cotton yarns were produced from the above systems and knitted in single jersey machine .The R…
Abstract Summery: A Ziegler‐Natta catalyst of MgCl 2 (ethoxide type)/TiCl 4 has been synthesized. In order to obtain ultra high molecular weight polyethylene (UHMWPE) tri‐isobutylaluminum which is less active to chain transfer was used as cocatalyst. Slurry polymerization was carried out for the polymerization of ethy…
In this study, Ga-doped ZnO (GZO) thin films were deposited on a sapphire substrate utilizing a magnetron sputtering approach. ZnO and Ga2O3targets were employed as the sputtering sources during a cosputtering deposition. After thermal annealing in nitrogen ambient conditions, the electrical resistivity and optical tr…

Tungsten disulfide (WS2) nanowires have been synthesized through a microwave-assisted chemical route that uses tungstic acid, elemental sulfur and monoethanolamine as starting reagents for obtaining a precursor solution of tetrathiotungstate ions. Acidification of the precursor solution yields amorphous precipitates,…
Epitaxial thin films of LaMnO3 were grown by pulsed laser deposition in identical deposition conditions but in situ annealed in different oxygen environments. All the films showed an insulator to metal transition. It also showed a magnetic order that correlates well with an insulator to metal behavior. The transition…
We propose a novel ferroelectric-gate field-effect transistor (FET) with a polar semiconductor channel, which is called a controlled-polarization-type ferroelectric-gate FET. The essential factor for this device is the stabilization of the spontaneous polarization of the ferroelectric film by the spontaneous polarizat…
