Polymer/perovskite manganese oxide (epoxy resin/La 0.8 Sr 0.2 MnO 3 ) composites are prepared using bonded method. There is no reaction between La 0.8 Sr 0.2 MnO 3 and the polymer. The nonlinear current–voltage property is significantly affected by the content of polymer. The resistivity and nonlinear coefficient incr…
Zinc sulphide (ZnS) nanoparticles were synthesized via simple, rapid and energy efficient microwave technique. The obtained nanoparticles were found to possess a cubic structure with an average particle size of less than 5 nm. By changing the microwave irradiation time from 5 to 30 min, the average size of nanoparticl…
This paper presents the synthesis of RNA-templated Zn 2+ /PbSe nanostructures following a colloidal approach. The nucleation and growth of PbSe on RNA matrix in the presence of Zn 2+ and Pb 2+ produces the porous Zn 2+ /PbSe building blocks through intramolecular folding, which in the process of self-assembly forms a…
Abstract Two zinc(II) and cadmium(II) metal‐organic frameworks with mixed ligands, {[Zn2(biim‐4)2(TDC)2]·2.5H2O}n (1) and {[Cd2(biim‐4)2(TDC)2·2H2O]}n (2) [biim‐4 = 1,1′‐(1,4‐butanediyl)bis(imidazole); H2TDC = thiophene‐2,5‐dicarboxylic acid], were hydrothermally synthesized. Both of them are characterized by elementa…
OBJECTIVE: To test engineered and native septal cartilage for resistance to deformation and remodeling under sustained bending loads and to determine the effect of bending loads on the biochemical properties of constructs. STUDY DESIGN: Prospective, basic science. SETTING: Laboratory. SUBJECTS AND METHODS: Human septa…
Single crystals of Au- and Ag-doped ReSe2 (ReSe2:Au and ReSe2:Ag) have been grown by chemical vapor transport (CVT) method using iodine as a transporting agent. The optical properties are studied by absorption and polarized-thermoreflectance (PTR) spectroscopy at different polarization angles in the temperature range…

The importance of structural biology has been highlighted in the past few years not only as part of drug discovery programs in the pharmaceutical industry but also by structural genomics programs. Although the function of a protein can be studied by several biochemical and or biophysical techniques a molecular underst…
Abstract The organically templated pentaborate [C10N2H9][B5O6(OH)4]·H3BO3·H2O (1a) was synthesized by boric acid and 4, 4′‐bipyridine in aqueous solution and characterized by single‐crystal X‐ray diffraction, elemental analysis, FTIR spectroscopy, thermogravimetric analysis, powder X‐ray diffraction, and photoluminesc…
The study described here combines materials science and engineering and mathematical analysis to fundamentally obtain insights underlying nanoscale deformation in polymer nanocomposites. The objective was achieved by examining the surface deformation response of two polymer nanocomposite systems with significant diffe…
This article reports the preparation and characterization of newly developed hybrid composites consisting of epoxy resin (EP) matrix, acetylated kenaf bast fiber (AKF) and conducting polyaniline (PANI) nanowires. Initially, the EP/AKF composites were prepared by varying the AKF loading (5–30 wt%). The EP/AKF displayed…
We investigate the spin wave spectra in a magnonic waveguide using the plane wave expansion method. The structure under the investigation has the form of thin strips of permalloy and cobalt, alternately arranged as a planar waveguide. The structure is assumed to be infinite in length and finite in thickness and width.…
In this study, we describe the most expected behavior of cells on the modified surface and the correlation between the modified substrates and the response of cells. The physicochemical characteristics of substrates played an essential role in the adhesion and proliferation of cells. Glass and polymer substrates were…
In order to enhance the photovoltaic property of the CdS/CdSe co-sensitized quantum dot sensitized solar cells (QDSSCs), the surface of nanoporous $TiO_2$ photoanode was modified by ultrathin $Al_2O_3$ layer before the deposition of quantum dots (QDs). The $Al_2O_3$ layer, dip-coated by 0.10 M Al precursor solution, e…
The thermomechanical degradation of blends made from polypropylene and polystyrene, with or without compatibilizer, was studied using an internal mixer coupled to a torque rheometer. The blends processed without compatibilizer presented regular and expected results regarding torque reduction, with evidence of chain sc…
Described are ferromagnetic resonance (FMR) studies of the long wavelength magnetostatic wave modes of a single crystal yttrium iron garnet (YIG) slab magnetized by an in-plane field. A resonant circuit comprising a coil, 50 μm in diameter, is used to excite and detect the YIG microwave absorption spectrum. By changin…
The studies of radionuclide distributions in foodstuffs and the environment provide vital radiological baseline information. This is essential in understanding human exposure from natural and man-made sources of radiation and also necessary in establishing rules and regulations relating to radiation protection. Anothe…
The relationship between the NMR methyl group axial order parameter and the side chain conformational entropy is investigated in inhibitor-bound and apo human HIV protease using molecular dynamics simulation. Three distinct entropic classes of methyl-bearing side chains, determined by the topological distance of the m…
Organic hybrid composites based on carboxylated nitrile rubber and nylon-12 reinforced with mercerized and diisocyanated lignocellulose residue (LCR) was prepared. The influence of the LCR on the viscoelastic properties of these organic hybrids was investigated by dynamic mechanical analysis and thermal analysis (diff…
Self-reinforced composite (SRC) has gained significant interest due to its lightweight and good recyclability. In the present work, SRCs were prepared from woven polypropylene tapes. The woven tapes were further stitched by lock stitch and its effects on flexural and impact properties of the composites were studied. F…
