Synthesis, Characterization of Nano Tin oxide Via Co-precipitation Method Pure SnO2 nano powders were synthesized by co-precipitation method. The structure, surface, optical, and functional groups were analyzed by X- ray diffraction, FESEM, UV-Vis spectroscopy, FTIR and fluorescence spectra, respectively. The results were compared with pure tin oxide nanoparticle. X-ray analysis shows that the obtained power has tetragonal rutile structure with average crystallite size of 34 nm. Band gap is observed from UV-Vis spectroscopy.Fluorescence spectrum of pure sample detected a strong emission peaks at 634nm due to surface defect and oxygen vacancies in SnO2 nanoparticles.

Improving hardness of stainless steel Cr18Ni10Ti through electrochemical machining One of the major mechanical and physical parameters for surface quality is a hardness. In this paper studied the electrochemical machining (ECM) to improve the surface micro-hardness and nano-hardness of stainless steel samples. The materials studied are used as samples of stainless steel Cr18Ni10Ti after electrochemical machining under different current density in a water solution NaCl with various concentrations.

Effects of the Magnetic Flux and the Rashba and the Dresselhaus Interactions on the Tunneling Nanoscale Magnetoresistance of a Three-Terminal Quantum Rings In this paper we investigate the effect of tunneling magnetoresistance in one-dimensional three-terminal mesoscopic ring in the presence of the magnetic flux and the Rashba spin-orbit interaction (RSOI) and the Dresselhaus spin-orbit interaction (DSOI). We calculate current flow in this structure based on the Landauer-Buttiker formalism and a generalized Green’s function technique for parallel and antiparallel spin orientations in ferromagnetic electrodes. Calculations show that the tunneling magnetoresistance increases with the strength of the magnetization. The required conditions for reach the maximum values of the tunneling magnetoresistanc is also calculated.
Эффекты магнитного потока и Рашбой и Дрессельхауза взаимодействий на туннельного магнетосопротивления наноразмерных трехтерминальной квантовой колец В этой статье мы исследуем влияние туннелирования магнетосопротивления в одномерном три терминала мезоскопическое кольцо в присутствии магнитного потока и спин-орбитального взаимодействия Рашбы (RSOI) и спин-орбитального взаимодействия Дрессельхауза (DSOI). Мы рассчитываем ток в этой структуре, основанной на формализме Ландауэр-Buttiker и обобщенной методики функции Грина для параллельных и антипараллельных ориентаций спина в ферромагнитных электродов. Расчеты показывают, что туннельное магнитосопротивление увеличивается с силой намагничивания. Также рассчитаны необходимые условия для достижения максимальных значений туннельного магнитоcопро.

Effects of the Rashba and the Dresselhaus spin-orbit interactions on the quantum transport and spin filtering in a three-terminal quantum ring The spin resolved conductance in a quantum ring with one input and two output leads in the presence of the Rashba spin-orbit interaction (RSOI) and the Dresselhaus spin-orbit interaction (DSOI) has been studied. The conditions needed for perfect spin polarization including the value of the Rashba and Dresselhaus coupling strength and the values of the electron energy are investigated coupled strongly with the leads. Our calculations are performed using the nonequilibrium Green’s function method and Griffith boundary condition in the framework of the tight binding model. It is shown that the spin-polarized transport and polarizability can be controlled by the RSOI and/or DSOI in the effects of applied magnetic field treading the ring but also on the bias applied between the input and output leads. Results of this paper can be used in designing perfect spin inverters. The effects of relative positions of the drain electrodes on the perfect spin polarization is also investigated.
Эффекты Рашбой и Дрессельхауза спин-орбитального взаимодействия на квантовом фильтрации транспорта и спина в трехтерминальной квантового кольца в Спина решен проводимость в квантовом кольце с одним входом и двумя выходными проводами в присутствии спин-орбитального взаимодействия Рашбы (RSOI) и Дрессельхауза спин-орбитального взаимодействия (DSOI) изучалась. Условия, необходимые для идеального спиновой поляризации в том числе значения напряженности Рашбы и Дрессельхауза связи и значения энергии электрона исследованы в сочетании сильно с выводами. Наши расчеты выполняются с использованием неравновесной Грина метод функций и Гриффит граничное условие в рамках сильной связи модели. Показано, что спин-поляризованный транспорт и поляризуемость можно управлять с помощью RSOI и / или DSOI в воздействии приложенного магнитного поля нажима кольцо, но и от смещения, прикладываемого между входными и выходными выводами. Результаты этой работы могут быть использованы при разработке совершенных спин инверторы. Эффекты относительных положений электродами стоков на отличном спиновой поляризации также исследуется.

The experimental investigation of production of Formaldehyde In this research, a comparison between the performance efficiency of silver catalytic water based reactor in nano and micro scale of catalyst is performed. Process simulation is done to find the dominant parameters in production of formaldehyde from methanol. Mass and energy conservation equations in cylindrical silver catalytic bed are written and solved simultaneously. The bed is discrete in triangular elements in both horizontal and radial dimensions. Conservation equations are solved simultaneously in each element for both micro and nano scale. Due to experiments, the optimum amounts of water to methanol and oxygen to methanol is 1 and 0.3, respectively. The product with 0.48 mol% formaldehyde is obtained using the optimum amount of 1 for water to methanol in feed in catalytic bed.
