General description
The mechanism of formation of protective scales of α-Al2O3 on surfaces of binary M-Al (M = Fe, Ni or Co) alloys at high temperatures has been studied. Activated aluminum oxides having different acidities and water concentrations (having Brockmann activity I-V) can easily detect various types of water (namely free water, pore water, and bound water) on the aluminum oxide present in soils.
Application
Aluminum oxide (Alumina, Al2O3) has been used in the preparation of one-step self-assembled double-helices of multiwalled carbon nanotubes (MWCNT) arrays (composed of Fe nanoparticles bound to SiOx micro-particles).
Aluminum oxide (neutral) has been used in the preparation of alumina supported silver (Ag/Al2O3) catalyst suitable for selective catalytic reduction of nitrogen oxides (NOx) by hydrocarbons (HC-SCR).
Packaging
Brockmann aluminum oxides are suitable for column chromatography and adsorptive filtration.

We demonstrated a promising route for enhancing temperature sensitivity, improving saturation voltage, and reducing power consumption of the MOS(p) tunneling temperature sensors by introducing ultrathin Al2O3 into the dielectric stacks. Detailed illustrations of the working mechanism and device concept are
