Heat-initiated oxidation of aluminum nanoparticles

2015
This dissertation uses multi-million atom molecular dynamics simulations to determine the key mechanisms which control the oxidation of aluminum nanoparticles (ANPs) due to uniform heating. The primary simulation studied is the oxidation of a 46 nm ANP uniformly heated to 1100 K (the melting temperature of aluminum metal is 933 K).

Immunization of mice with peptomers covalently coupled to aluminum oxide nanoparticles

Vaccine, 1999
Subunit vaccines generally require adjuvants to elicit immune responses, but adjuvants may alter the conformation of critical epitopes and reduce vaccine efficacy. We therefore tested an immunization strategy in which antigen is covalently coupled to aluminum oxide nanoparticles using a method that favors preservation of the native conformation.

Cytotoxic and genotoxic characterization of aluminum and silicon oxide nanoparticles in macrophages

Dental Materials, 2015
Although aluminum oxide and silicon oxide nanoparticles are currently available as dental materials, there is a lack of basic information concerning their biocompatibility. This study evaluates the biological responses of cultured macrophages (RAW264) to aluminum oxide (Al2O3NPs) and silicon oxide nanoparticles (SiO2NPs) by analyzing cytotoxicity and ...

Synthesis of oxide-free aluminum nanoparticles for application to conductive film

Nanotechnology, 2018
Abstract Aluminum nanoparticles are considered promising as alternatives to conventional ink materials, replacing silver and copper nanoparticles, due to their extremely low cost and low melting temperature. However, a serious obstacle to realizing their use as conductive ink materials is the oxidation of aluminum.

Oxidative stress response to aluminum oxide (Al2O3) nanoparticles in Triticum aestivum

Biologia, 2018
The development of nanotechnologies has increased the amount of manufactured metal oxide nanoparticles in the environment. In the view of nanoparticle dispersion to the environment, assessment of their toxicity becomes very crucial. Aluminum oxide (Al2O3) nanoparticles have wide range of use in industry as well as personal care products.

Abrasive properties of aluminum iron oxide nanoparticles

Inorganic Materials, 2009
Aluminum iron oxide nanoparticles have been prepared by heat-treating ammonium hydroxycarbonate complexes with the general formula NH4Al2Fe(OH)5(CO3) · nH2O and have been characterized by X-ray diffraction, IR spectroscopy, differential thermal analysis, scanning electron microscopy, and particle size analysis. The mixed oxide α-Al2 − xFexO3 with x = 0.

Nanoenergetic Composite of Mesoporous Iron Oxide and Aluminum Nanoparticles

Journal of Energetic Materials, 2006
Ordered mesoporous Fe2O3 was synthesized using cetyltrimethylammonium chloride (CTAC) and polyethylene glycol octadecyl ether (Brij 76) surfactant templates. The gel time was monitored as a function of the concentration ratio of precursor to the surfactant.

Tailoring oxidation of aluminum nanoparticles reinforced with carbon nanotubes

AIP Conference Proceedings, 2016
In this report, the oxidation temperature and reaction enthalpy of Aluminum (Al) nanoparticles has been controlled by reinforcing with carbon nanotubes. The physical mixing method with ultrasonication was employed to synthesize CNT/Al nanocomposite powders. The micro-morphology of nanoconmposite powders has been analysed by scanning electron microscopy,
