Properties of Amorphous Transparent Conducting and Semiconducting Oxides from First Principles
<p>"Amorphous transparent conducting and semiconducting oxides possess properties superior or comparable to their crystalline counterparts. The structure-property relationship in amorphous oxides is not nearly as well understood as in the case of the crystalline transparent conducting oxides. We …

Predicting thermodynamic and transport parameters for metal contaminant sorption to hydrated metal oxides in aquatic systems
Hydrated oxides such as HAO,'HFO, goethite, and BA40 are prevalent in soils and sediments as discrete particles or as coatings. These microporous oxides have large surface areas and high affmity for metal ions, and hence they act as both a sink and a source for anthropogenically released metal …

An electrochemical study on the ionic conductivity of ceramic electrolyte La1-2SrxCo3-yMyO3-sigma oxide and its Pd/Ag compsites
… of La1-xSrxCo1-yMyO3-d perovskite-type oxides that possess excellent electronic and oxygen anionic conductivity. Such mixed-conductivity is the essential property that the cathode material of solid oxide fuel cell (SOFC) and the electrochemical oxygen separation membrane must have. The …

Meteoric 10Be as a Tracer for Subglacial Chemical Weathering in East Antarctica
… particles in aqueous solution, precipitate with amorphous oxides, and/or be incorporated into authigenic clay structures during chemical weathering. The presence of 10Be in weathering products derived from beneath the ice therefore indicates chemical weathering processes in the subglacial …

In-Situ-Messungen der mechanischen Spannungen in gesputterten Metall- und Oxidschichten
… stresses. Changes between the different oxides have also been found in the beginning of growth. The amorphous oxides niobium oxide and titanium oxide exhibit tensile stresses in the beginning of growth, while the crystalline oxides zinc oxide and zirconium oxide no tensile stresses can be …

Effect of Synthetic Chelating Agent Application to Soils on Phosphorus Availability
… chemical bonds with iron (Fe) and aluminum (Al) amorphous oxides. Organic chelating agents form strong bonds with metals in soil and may reduce P binding with Fe and Al. Ethylenediamine tetraacetic acid (EDTA), hydroxyethyl ethylenediamine triacetic acid (HEEDTA), gluconic acid (GA), and citric …

Understanding and Controlling the Surface Chemistry of Oxides to Enhance Catalytic Activity at Elevated Temperatures
Oxides have been extensively used as high temperature catalysts in electrochemical devices and for gas conversion reactions, including solid oxide fuel cells (SOFC), solid oxide electrolysis cells (SOEC), ethane cracking, CO oxidation, and the oxidative coupling of methane. In hightemperature …
