Hardness and friction behavior of bulk CoAl2O4 and Co–Al2O3 composite layers formed during Spark Plasma Sintering of CoAl2O4 powders [PDF]
Materials made up of a Co–Al2O3 composite coating over a CoAl2O4 core are prepared during Spark Plasma Sintering of CoAl2O4 powders. The Co particles are precipitated because of a combination of high temperature and low O2 partial pressure.

Analysis of Electron Mobility in Inversion-Mode Al2O3/InxGa1-xAs MOSFETs [PDF]
The electron mobility in Al2O3/InxGa1-xAs (x = 0.53, 0.65, or 0.75) metal-oxide-semiconductor field-effect transistors was analyzed for scattering by oxide charge, as well as interface charge and roughness, and compared with measured transfer ...

Quantification of High Temperature Transition Al2O3 and Their Phase Transformations [PDF]
High temperature exposure of gamma-Al2O3 can lead to a series of polymorphic transformations, including the formation of delta-Al2O3 and theta-Al2O3. Quantification of the microstructure in the delta/theta-Al2O3 formation range represents a formidable ...

SO2 Reactions over γ-Al2O3,Pt/γ-Al2O3,Sn/γ-Al2O3 and Pt–Sn/γ-Al2O3
Abstract Platinum and Platinum–tin bimetallic catalysts supported on alumina were prepared by co-impregnation of both metallic precursors on the support and used as catalysts for the oxidation of SO 2 . Platinum dispersion was determined by means of H 2 –O 2 titration.
