The Oxidation Mechanism of CdTe (110) Surface
Using a first-principles pseudopotential technique within a generalized gradient approximation of the density functional theory, we have investigated the mechanism of adsorption of molecular oxygen on the CdTe(110) surface. The determination of the more favorables structures and their formation through the activation barrier analysis indicates that the formation can occur in the regimes of low ...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولLaser desorption/ionization mass spectrometry on porous silicon for metabolome analyses: influence of surface oxidation.
Laser desorption/ionization mass spectrometry (LDI-MS) on porous silicon is a promising analytical strategy for the rapid detection of metabolites in biological matrices. We show that both oxidized and unoxidized porous silicon surfaces are useful in detecting protonated/deprotonated molecules from compounds when analyzed in mixtures. We demonstrate the feasibility of using this technique for t...
متن کاملSurface Oxidation of Carbon Nanofibres
Carbon nanofibres of the fishbone and parallel type were surface-oxidised by several methods. The untreated and oxidised fibres were studied with infrared spectroscopy, thermogravimetric analysis and XPS. Oxidation in a mixture of concentrated nitric and sulfuric acid turned out to be the most effective method for creating oxygen-containing surface groups. This treatment results not only in the...
متن کاملSurface oxidation of liquid Sn
Wereport the results of anX-ray scattering study that reveals oxidation kinetics and formation of a previously unreported crystalline phase of SnO at the liquid–vapour interface of Sn. Our experiments reveal that the pure liquid Sn surface does not react with molecular oxygen below an activation pressure of 5.0 · 10 Torr. Above that pressure a rough solid Sn oxide growsover the liquidmetal surf...
