1. Improved Oxidation Resistance and Reduced Cr Vaporization from Thin-Film Coated Solid Oxide Fuel Cell Interconnects
Abstract : High electrical efficiency, clean emissions, and the possibility to operate on a great variety of fuels, such as hydrogen, alcohols and hydrocarbons are some advantages of Solid Oxide Fuel Cell (SOFC) technology. Too short lifetimes and high production costs have, however, limited the commercialization of this technology. READ MORE

2. The rule of hydrogen and rare earth metals in the formation of protective metal-oxides
Abstract : The effects of hydrogen and rare earth metal (REM) additionson the oxidation behavior of metals and alloys that formchromia, alumina and zirconia in 20 mbar O2and/or H2O have been investigated at elevated temperatures.The metal-gas reactions were studied by the use of isotopicallylabeled gas in combination with mass spectrometry and bymeasuring changes in the total pressure in a closed reactionchamber.

4. Weathering of mining waste rock containing alum shale and limestone
Abstract : Geochemical processes occurring in the waste rock dumps ofan old phosphate mine, located in Maardu, northem Estonia, havebeen studied and modelled. The waste rock contains pyritic,metalliferous and organic-rich shale, as well as limestone.Production of acidity during pyrite oxidation is a potentialmechanism for heavy metal release. READ MORE
