Although the selection of film materials grown by ALD is wide, many technologically important materials (Si, Ge, Denitrifying bacteria
Denitrifying bacteria form a necessary part of the process known as denitrification as part of the nitrogen cycle, their primary purpose being to metabolise nitrogenous compounds, with the assistance of the nitrate reductase enzyme, to turn oxides back to nitrogen gas or nitrous oxides for energy generation.
Vollhardt is one of the founders of the Dynamical Mean-Field Theory (DMFT) for strongly correlated electronic solids such as transition metals (e.g. iron or vanadium) and their oxides, i.e. materials with electrons in open d- and f-shells.
Iron oxide adsorption treatment for arsenic in groundwater is a commonly practiced removal process which involves the chemical treatment of arsenic species such that they adsorb onto iron oxides and create larger particles that may be filtered out of the water stream.
Most usable metallic ores in the Earth's crust are oxides or sulfides, and as such do not manifest the properties of refined metals.
However, the predictions of structure are more difficult for ternary oxides.
•
The structure of binary oxides can be predicted on the basis of the relative sizes of the metal and oxide ions and the filling of holes in a close packed oxide lattice.
This phase is thermodynamically unstable at room temperature with respect to the binary oxides synthesised by heating stoichiometric quantities of these oxides together and then quenching the material by rapidly cooling it from approximately 900 °C to room temperature.
