In this study, microstructure evolution and dielectric properties of SrTiO3 ceramic have been investigated, whereby mechanical activation powders was used to modify the functional materials. Microstructural SEM analysis ceramics showed that increase in time results less porous samples. Raman spectroscopy indicated changes broadening asymmetry TO2 mode with a change activation. Fano due its inte...

in this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (swcnt) is reported. methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. some physical properties of the methanol-water mixture such as r...

       Antimicrobial activity of the polar and nonpolar extracts of the roots and aerial parts of Peucedanum ruthenicum M. Bieb., Johreniopsis seseloides (C. A. Mey.) Pimenov and Cervaria cervariifolia (C. A. Mey.) Pimenov were examined against gram-positive and gram-negative bacteria. The polar extracts of the roots and aerial parts displayed no activity against bact...

The kinematics and the balance equations for multiphase micro-architectured materials such as foams, textiles, or beam-like structures exhibit a peculiar macroscopic behavior. The topology and mechanical properties of their structural constituents at the microscale induce this behavior. The derivation of the effective mechanical properties of 2D and 3D lattices made of articulated beams is here...

PVDF nanofibers are prepared using electrospinning. The effect of addition of a hydrated salt, nickel chloride hexahydrate (NiCl(2)·6H(2)O), on the phase formation is examined. Addition of the hydrated salt (NC) is found to enhance the polar β phase by about 30%. The peak to peak piezo-voltage generated for PVDF NC is almost 0.762 V, a factor of 3 higher than that for PVDF. The fiber mats exhib...
