Analysis of Cr Atoms Three-Dimensional Deposition Characteristics
(Scientific Research, 2011-09)The semi-classical model is used to simulate the three-dimensional trajectory and deposition distribution of the chromium atoms in the Gaussian laser standing wave field using the Runge-Kutta method, and then the three ... -
Modelling of Internal Stresses in Sheet Glass during the Cooling
(Scientific Research, 2011-06)Internal stresses in glass are generated by interactions between thermal contraction, elasticity at low temperatures, viscoelastic flow at higher temperature, and temperature gradients caused by cooling. This work intends ... -
The Chain Reaction of Atmospheric Nitrogen Oxidation, Initiated by an Electric Discharge in Air
(2015-11)The data, concerning to the nitrogen oxidation reaction, initiated by electrical discharge, are reviewed in this article. The reviewed data lead to conclusion that critical concentrations of NO molecules and NO3 radicals ... -
A Benchmark Study on the Properties of Unsubstituted and Some Substituted Polypyrroles
(2015-11)The geometric, thermodynamic, electronic and absorption properties of Pyrrole and some of its derivatives have been carried out using CCSD/6-311++G(d,p)/STO-3G, TD-DFT and DFT/B3LYP/6-31G(d) from monomer to five repeating ... -
Biophysical EPR Studies Applied to Membrane Proteins
(2015-11)Membrane proteins are very important in controlling bioenergetics, functional activity, and initializing signal pathways in a wide variety of complicated biological systems. They also represent approximately 50% of the ... -
Non-thermal Influence of A Weak Microwave on Nerve Fiber Activity
(2014-10)This paper presents a short selective review of the non-thermal weak microwave field impact on a nerve fiber. The published results of recent experiments are reviewed and analyzed. The theory of the authors is presented, ... -
Formation and Interaction of Bright Solitons with Shape Changing in a DNA Model
(2014-09)I explore the collision of localized structures that arise from a general initial solutions in the Peyrard- Bishop model. By means of the semi-discrete approximation, it is shown that the amplitudes of waves are described ... -
Synthesis and Modification of Carboxylated Multi Wall Nanotubes with Atenolol
(Scientific Research, 2014-07)In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using atenolol as a class of drugs that were used in cardiovascular diseases containing reactable nitrogen, which could attach chemically to ... -
Multiscale Modeling of Exocytosis in the Fertilization Process
(2014-09)We discuss the implementation of a multiscale biophysico-chemical model able to cope with the main mechanisms underlying cumulative exocytosis in cells. The model is based on a diffusion equation in the presence of external ... -
Synthesis of Luminescent CdTe Nanorods on Anodized Aluminum Oxide Template and Their Utility in Divalent Heavy Metal Ion Sensing
(Scientific Research, 2014-07)A simple one-pot hydrothermal method to grow luminescent CdTe nanorods on porous anodized aluminum oxide (AAO) template is described. These CdTe nanorods on the AAO template were further applied as an optical probe to ... -
The Role of Hole Traps in DNA
(2014-07)Two types of whole trap have been discussed for DNA. One type was introduced by Reynaud et al. (Jour. Am. Chem. Soc. 2013, 135, 3953) to account for the properties of whole conduction in an adeninethymine (AT) DNA. In their ... -
Theoretical Treatment of Ion Stopping in Complex Systems
(2014-08)The sort of materials treated by theoretical methods in physics has changed radically in recent years, from small molecules and biomolecules, as well as perfect solids and gasses at zero temperature, to much more complex ... -
Possible Synergistic Effect and Antioxidant Properties of Chitosan Nanoparticles and Quercetin against Carbon Tetrachloride-Induce Hepatotoxicity in Rats
(Scientific Research, 2015-04)This study was conducted to prepare chitosan nanoparticles (CNPs), to determine their properties and to evaluate the synergistic protective role of CNPs alone or in combination with quercetin (Q) against oxidative stress ... -
Optical and Electrical Properties of Nanocrystalline SnO2 Thin Films Synthesized by Chemical Bath Deposition Method
(Scientific Research, 2015-10)The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface ... -
