Fluid hydrogen, oxygen, and nitrogen at very high pressures and temperatures demonstrate high conductivity close to the so-called “minimum metal conductivity”. Electrophysical properties of these liquids in the semi-conducting transition region are practically unknown. In this work a simple model is used for estimating the bottom energy of the electron conduction band and the electron-forbidden gap...
By using density functional theory (DFT) at B3LYP/6-31G* levels, The effect of optimized geometries and binding energies of morpholinium ionic liquid have been studied by different anions or cations. The computed results indicate that the ionic liquid formed by different anions and cations has three structures (mon, nop, orth) and six positions. Three hydrogen bond have been formed in each position...
Photoelectrocatalytic (PEC) degradation and electrodegradation (ED) of methyl orange were investigated in aqueous NaCl, NaHCO3 and Na2SO4 solutions. The effects of electrolytes concentration and applied potential were studied in the above two processes. Photocatalytic oxidation (PCO) was also performed in TiO2(P25) suspension under UV-irradiation for comparison. Enhanced decolorization performance...
The conventional method for the detection of soil nitrate and chlorine are time-consuming and expensive. The method for rapid and low-cost detection of soil nitrate and chlorine are urgently needed. In this study, a soil nitrate and chlorine rapid simultaneous detection system was developed based on two ion-selective electrodes (ISEs). The potentiometric experiments were conducted to evaluate the...
Summary form only given. Solitary waves are the waves of permanent form which arise from a certain class of nonlinear partial differential equations and preserve their shape while traveling over large distances. Solitary waves are called solitons if they emerge with their original shape and speed after having collision with other solitary waves. Propagation of ion acoustic solitary waves in plasma...
Some general aspects of the sheath structure in electronegative plasmas are analysed, through an extensive review of the authors' contributions to this subject. In this work, the one dimensional collisionless sheath model of electropositive plasmas is investigated extended here to study the sheath structure of an electronegative plasma at steady state in the presence of negative ions and planar sheath...
The UW-Inertial Electrostatic Confinement (IEC) device is comprised of concentric, nearly transparent, spherical metallic grids within a cylindrical vacuum vessel. The central grid, which can be held at high negative potentials (~ -100 to -200 kV) is the device cathode, while the outer grid, held at ground potential, is the device anode. This configuration accelerates ions, created near the anode,...
We analyze the AC electro-osmotic motion of a 1:1 aqueous solution, taking into account the difference in mobilities and diffusion coefficients between positive and negative ions. This model serves to understand the behavior of common systems as a solution of NaCl in water. We pay special attention to two cases. First, the case of slightly different mobilities, that can model a KCl solution. Second,...
