Nowadays, the studies on absorption spectra of Ag-doped ZnO have given two distinctly different experimental results, that is, the red shift or blue shift when the mole fraction of the impurity increases in a range from 0.0278 to 0.0417. To solve this contradiction, according to the first-principles plane-wave pseudop…
To meet the requirements for high speed, low cost, and more information capacity, silicon photonics has been booming in recent years. Silicon photonics covers a very wide field. For the silicon photonics, researchers have successfully achieved silicon-based optical waveguides, switches, modulators, and detectors. But…
The influences of medium and temperature on the shear thickening behavior of silica colloids are investigated. The nano fumed silica colloids in four media (ethylene glycol, polyethylene glycol 400, propylene glycol, and polypropylene glycol 400) exhibit continuous or discontinuous shear thickening behaviors. With the…
The effect of amodiaquine on corrosion of mild steel in hydrochloric acid was investigated by linear polarization resistance (LPR) electrochemical method. The results indicated that corrosion inhibition efficiency and degree of surface coverage were increased with rise in the concentration of amodiaquine. The inhibito…
Pleurotus, commonly known as oyster mushroom, is a wood rotting mushroom that naturally grows on decaying logs. This mushroom has been cultivated using saw dust based substrate formulation. This study was undertaken to evaluate the growth performance of Pleurotus citrinopileatus, Pleurotus djamor and Pleurotus salmone…
Longer use and responsible disposal of rapidly discarded consumer electronics would slow material throughput and reduce metal extraction rates and associated environmental impacts. Although longevity is technically achievable, extending product lifetimes is more challenging when devices become ‘tired’, ‘worn’ or ‘dama…
Simultaneous measurements of small-angle X-ray scattering with stress-strain tests were conducted to reveal changes in microphase-separated structures being correlated with changes in the mechanical properties upon the uniaxial stretching of an elastomeric block copolymer film containing glassy spherical microdomains…
The presented new methodology for full numerical simulating performances of casing rupture integrates the finite element method and the stochastic failure theory in the solvers for 2D and 3D axis-symmetric analyses of the projectile fragmentation. This paper focuses on the effects of the type of casing on the fragment…
Lithium based battery type supercapacitors has replaced the batteries for electric energy storage. A novel improved occurs in energy density and the electrodes carried the good electrochemical performances of specific capacitance, charge-discharge, high power density and high life cycle. In this paper describes, the l…
The aim of this study was to assess the toxic effect of the newly developed contraceptive RISUG-M in female Charles Foster rats.
The role of solute hydrogen and hydrides in the degradation of the mechanical properties of pure titanium was examined in this study. Commercially pure (99.5%) titanium was electrolytically charged with hydrogen from 50 to 2500 mass ppm and then heated in Ar at 723 K for 3 h to obtain a homogeneous solution of hydroge…
Nanoparticles (NPs) are literally and figuratively infiltrating all fields of biological research. They are sophisticated tools that can be customized, either by smart engineering or by the attachment of specific ligands, to match the requirements of a particular task. Through their inherent and functionalized propert…
From September 2001 to December 2004, 25 patients underwent a Fontan procedure using tissue-engineered vasculature (TEV) under informed consent and institutional review board approval [1]. Six of these 25 patients died, although no graft-related mortality occurred. The case presented herein is the first case in which…

FIBRES & TEXTILES in Eastern Europe 2015; 23, 2(110): 33-39. Study on Woven Fabric Structure Using 3D Computer Image Analysis for In-Depth Identification of Thr…
The electrochemical behavior of an α,β ' -brass CuZn40Pb2 (CW617N) was studied in basic nitrate solutions with various basic pHs and nitrate ion concentrations. In all the chosen experimental conditions, corrosion at the open circuit potential proceeded by the galvanic coupling of the α and β ' phases, leading to a su…
Nanocrystalline Ni0.7Zn0.3Fe2O4 was prepared by solid-state reaction from stoichiometric mixture of ZnO, NiO, Fe2O3 powders. After preparation, it was grinded at different times. The X-ray powder diffractometry (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and vibrating…
With the advent of LC-MS, identification and characterization of compounds from plant origin has become very easy now a day. In this effort, several plant-based compounds have been identified possessing therapeutic propensities. This category includes cruciferous vegetables, garlic, ginger, onions, soybeans, and turme…
Low intensity warfare had many impact on reducing logistic costs during field operations. It influenced the development of new large caliber HE projectiles. Concerning increasing lethal efficiency at target, the focus is at development of modern projectiles with natural, embossed and preformed fragmentation. Modern na…
Flower-structured nickel oxide nanoparticle (NiONP) with flower size ~ 400-700 nm and petel size (individual nanoparticle) ~ 100 diameter have been successfully fabricated via an optimized thermo-decomposition technique using a dinuclear nickel(II)-Schiff base precursor. The template-free method is facile and effectiv…
Increasing performance requirements in a variety of markets and regulations toward more sustainable products and processes globally has led to high interest and investment in the chemical industry to research the properties of bio-based feedstocks as a sustainable and economical alternative to petroleum. This paper wi…
