Naturally occurring manganese (Mn(iii/iv)) oxides are ubiquitous in a wide range of environmental settings and play a key role in numerous biogeochemical cycles. In addition, Mn(iii/iv) oxides are powerful oxidants that are capable of oxidizing a wide range of compounds. This review critically assesses the reactivity of Mn oxides with organic contaminants. Initial work with organic reductants e...

The scaling of complementary metal oxide semiconductor (CMOS) transistors has led to the silicon dioxide layer used as a gate dielectric becoming so thin (1.4 nm) that its leakage current is too large. It is necessary to replace the SiO2 with a physically thicker layer of oxides of higher dielectric constant (κ) or ‘high K’ gate oxides such as hafnium oxide and hafnium silicate. Little was know...

The development of high-performance transparent conducting oxides is critical to many technologies from transparent electronics to solar cells. Whereas n-type transparent conducting oxides are present in many devices, their p-type counterparts are not largely commercialized, as they exhibit much lower carrier mobilities due to the large hole effective masses of most oxides. Here we conduct a hi...

conclusions application of zinc oxide as the photocatalyst can be effective in the removal process. background one of the important achievements of the past decade was the rapid growth of industries and accordingly production of various chemical compounds. objectives this study presents a combined system of photocatalytic oxidation and absorption solution to remove nitrogen oxides from polluted...

the nanoparticles of ti-si mixed oxides (ntso) with rutile structure were prepared by sol-gel method in a mixture of alcohol and water as solvent. the solid product was characterized by xrd, ftir, sem, tem, uv, tga and laser raman spectroscopy. the catalytic activity of ntso (5-10 nm) was investigated in the epoxidation of cis stilbene, trans stilbene, and norbornene by using oxidants such as t...

The perovskite structure is one of the most versatile structures for tailoring the properties of materials. The range of properties of perovskites varies from superconductivity to ferroelectricity, magnetoresistance to magnetocapacitance, and laser host properties to name a few. In particular, the perovskite oxides have been explored for their dielectric and magnetic properties. Traditionally, ...

Metal oxides are a group of compounds that are now intensively studied because of their wide use in modern ceramic materials, composites, nano-composites, etc., with new special properties. Many oxides are used as electronic materials for their electrical, magnetic and optical properties. The mechanisms of corrosion of metals and their alloys, as well as the mechanism of reduction in metallurgi...

The reactions between fifteen carbonyl oxides and water have been investigated with the aim of contributing to a better understanding of the effects of the substituents in the reactivity of carbonyl oxides. We have employed density functional theory and large scale ab initio methods (CCSD(T), CASSCF, and CASPT2), combined with transition state theory, to investigate the addition of water to car...

ÐSurface coatings (bio®lms and associated minerals) were collected on glass slides in the oxic surface waters of Cayuga Lake (New York State, U.S.A.) and were used to evaluate the relative contributions of Fe, Mn and Al oxides and organic material to total observed Pb and Cd adsorption by the surface coating materials. Several alternative selective extraction techniques were evaluated with resp...
