The chemical compositions, structures, and electrokinetic potentials have been studied for silver-containing Janus-type ZnO/Ag nanoparticles, heterophase Cu/Ag nanoparticles with a uniform distribution of the components over a particle, and silver-decorated TiO2 nanoparticles. The nanoparticles have been obtained by the simultaneous electric explosion of two wires. The influence of nanoparticle surface structure on the isoelectric point position and electrokinetic potential values has been analyzed. The effect of silver localization on the electrokinetic characteristics of nanoparticles has been investigated. These characteristics have been compared with those of mechanical mixtures having the same mass ratios of the components. [ABSTRACT FROM AUTHOR]

The experimental results of a study dealing with the effects of disaggregation of aqueous suspensions of AlN/Al nanopowder on the morphology of low-dimensional aluminum oxyhydroxide structures formed during their oxidation with water are reported. The shape, size, specific surface area, phase composition, and agglomeration of low-temperature structures are investigated. The structural formulas of aluminum oxyhydroxides as a function of conditions of their preparation are established. The conditions for the formation of aluminum oxyhydroxide nanosheets (2D-structures) are found, and the process for the formation of lowdimensional structure agglomerates is examined.
