Structure of Amorphous Aluminum Oxide
Physical Review Letters, 2009Whereas prototypical Al(2)O(3) is not a glass former, amorphous Al(2)O(3) can be formed as thin films through vapor deposition and can serve as a structural model for the Al(2)O(3) glass. The first two-dimensional solid-state NMR experiments for amorphous Al(2)O(3) thin film reveal that four- and five-coordinated species are predominant (95%), while ...

Oxidation and ignition of aluminum nanomaterials
Physical Chemistry Chemical Physics, 2013The oxidation and ignition of aluminum nanoparticles with a mean diameter of 150 nm are investigated with the help of simultaneous thermal analysis, X-ray powder diffraction, energy dispersive X-ray spectra analysis (EDS) and scanning and transmission electron microscopy at heating rates of 2-30 K min(-1).

Oxidation and Melting of Aluminum Nanopowders
The Journal of Physical Chemistry B, 2006Recently, nanometer-sized aluminum powders became available commercially, and their use as potential additives to propellants, explosives, and pyrotechnics has attracted significant interest. It has been suggested that very low melting temperatures are expected for nanosized aluminum powders and that such low melting temperatures could accelerate ...

Theoretical Study of the Reactions of Ethanol with Aluminum and Aluminum Oxide
The Journal of Physical Chemistry A, 2015Quantum chemical calculations with the use of B2PLYP method were carried out to study the reactions of Al and AlO with the C2H5OH molecule. The values of energy barriers were estimated by means of extrapolation to the basis set limit. Examination of the potential energy surface revealed the energetically favorable reaction pathways.

The main characteristics of aluminum oxides and hydroxides obtained by mechanochemical oxidation of aluminum powder, both in the initial state and after their heat-treatment in the interval 150 – 1100°C, are compared. The conditions for obtaining pseudoboehmite by thermal activation of mechanically oxidized product were established.

Abstract Luminescence methods are described for detecting polycyclic aromatic hydrocarbons (6-, 5-, 4-, and 3-ring) on aluminum oxide after separation by dry-column chromatography. A method is reported for standardizing the water content in the aluminum oxide used for dry-column chromatography.

The pro-oxidant activity of aluminum
Free Radical Biology and Medicine, 2004Aluminum, a non-redox-active metal is, nevertheless, a pro-oxidant both in in vitro preparations and in vivo. It facilitates both superoxide- and iron-driven biological oxidation by mechanisms that remain to be resolved. More than 10 years ago Fridovich and colleagues suggested that the facilitation of superoxide-driven biological oxidation by aluminum
