Importance of Phase Change of Aluminum in Oxidation of Aluminum Nanoparticles
The Journal of Physical Chemistry B, 2004Aluminum nanoparticles have increasingly gained attention because of their potential incorporation in explosive and propellant mixtures. This letter reports on a qualitative study on the oxidation of aluminum nanoparticles containing a passivating oxide coating.

Freeze-thaw stability of aluminum oxide nanoparticles
International Journal of Pharmaceutics, 2021The use of inorganic nanoparticles (NPs) gains interest for pharmaceutical applications, e.g. as adjuvants or drug delivery vehicles. Colloidal stability of NPs in aqueous suspensions is a major development challenge. Both frozen and lyophilized liquids are alternative presentations to liquid dispersion.

Controlled oxidation of aluminum nanoparticles
Advanced Powder Technology, 2015Abstract A theoretical and experimental analysis of the oxidation of aluminum nanoparticles is presented. The modeling of the oxidation is based on a modified Mott–Cabrera model. Mass and heat transfer, both at individual particle level are implemented.

Biodistribution and toxicity of spherical aluminum oxide nanoparticles
Journal of Applied Toxicology, 2015AbstractWith the rapid development of the nano‐industry, concerns about their potential adverse health effects have been raised. Thus, ranking accurately their toxicity and prioritizing for in vivo testing through in vitro toxicity test is needed. In this study, we used three types of synthesized aluminum oxide nanoparticles (AlONPs): γ‐aluminum oxide ...

Size-dependent nanoparticle reaction enthalpy: Oxidation of aluminum nanoparticles
Journal of Physics and Chemistry of Solids, 2011Abstract Here we present a model describing the particle size dependence of the oxidation enthalpy of aluminum nanoparticles. The model includes the size dependence of the cohesive energy of the reactant particles, the size dependence of the product lattice energy, extent of product agglomeration, and surface capping effects. The strongest effects on

Aluminum Oxide Nanoparticles in Cement Mortar
Materials Performance, 2012Compressive, tensile, and flexural strength of cement mortar containing 1, 3, and 5 wt% of aluminum oxide (Al2O3) nanoparticles were investigated. Samples containing 1 and 3 wt% Al2O3 nanoparticles show better mechanical properties than ordinary cement mortar. Increasing Al2O3, nanoparticles more than 5 wt% reduces the mechanical strength.

Heat-Initiated Oxidation of an Aluminum Nanoparticle
MRS Proceedings, 2012ABSTRACTMultimillion-atom reactive molecular dynamics simulations were used to investigate the mechanisms which control heat-initiated oxidation in aluminum nanoparticles. The simulation results reveal three stages: (1) confined burning, (2) onset of deformation, and (3) onset of small cluster ejections.

TiB2 nanoparticles-regulated oxidation behavior in aluminum alloy 7075
Corrosion Science, 2021Abstract In this paper, we studied the oxidation behavior in AA7075 containing TiB2 nanoparticles. The results indicate that TiB2 nanoparticles play distinctive roles during the coupled oxidation processes. At a lower temperature, TiB2 ruptures the Al2O3 film and refine the microstructure and morphology.
