Coarsening of metal oxide nanoparticles

Physical Review E, 2002
In solution phase synthesis of nanoparticles, processes such as coarsening and aggregation can compete with nucleation and growth in modifying the particle size distribution in the system. We show that coarsening of ZnO and TiO2 nanoparticles in solution follows the Lifshitz-Slyozov-Wagner rate law for diffusion controlled coarsening originally derived

Metal oxide encapsulated nanoparticles

Journal of Materials Chemistry, 2003
Atomistic computer simulation techniques have been employed to generate a model for a 25 nm3 CaO nanoparticle, encapsulated within the near surface region of an MgO lattice. We find that the ‘internal’ morphology of the resulting encapsulated CaO nanoparticle is ‘pseudo-spherical’ and exhibits {100}, {110} and {111} facets.

Metal oxide nanoparticles with low toxicity

Journal of Photochemistry and Photobiology B: Biology, 2015
A number of different nanomaterials produced and incorporated into various products are rising. However, their environmental hazards are frequently unknown. Here we consider three different metal oxide compounds (SnO2, In2O3, and Al2O3), which have not been extensively studied and are expected to have low toxicity.

Aggregation-Dependent Oxidation of Metal Nanoparticles

Journal of the American Chemical Society, 2017
Here we describe the effect of aggregation on the oxidation of citrate-stabilized Au nanoparticles (NPs) attached electrostatically to amine-functionalized glass/ITO electrodes. When the Au NPs are attached to the electrode from a solution with pH greater than ∼3.0, they are well-separated on the electrode and oxidize in bromide-containing electrolyte ...

Peptide binding to metal oxide nanoparticles

Faraday Discussions, 2017
Magnetic metal oxide nanoparticles demonstrate great applicability in several fields such as biotechnology, medicine and catalysis. A stable, magnetic and low-cost material, nanoscale magnetite, is an interesting adsorbent for protein purification.

Complex Oxide–Noble Metal Conjugated Nanoparticles

Advanced Materials, 2013
Hybrid nanoparticles (NPs) composed of multiple components offer new opportunities for next-generation materials. In this study, a paradigm for the noble metal/ternary complex oxide hybrid NPs is reported by adopting pulsed laser ablation in liquids. As model hybrids, gold-spinel heterodimer (Au-CoFe2O4) and gold-pervoskite heterodimer (Au-SrTiO3) NPs ...
