Studies of copper–silver glass–metal nanocomposites

Abstract

The studies of bimetallic nanocomposites made in glass by metal ion exchange process and heat treatment in hydrogen atmosphere are presented. The distributions of silver and copper nanoparticles in glass are obtained using secondary ion mass spectrometry measurements and optical absorption spectroscopy. It was shown that in bimetallic nanocomposites containing silver and copper inclusions, copper nanoparticles are closer to the surface than silver ones, and quasi-layered structure of copper nanoparticles can be formed.

Peculiarities of fullerenes and carbon onions application for reinforcing the aluminum matrix in the metal matrix composites

“…Much attention is devoted to the development of new composites, since they can exhibit the properties unattainable in conventional nonreinforced materials . Many investigators have studied aluminum matrix composites with carbon reinforcements and possible reaction between aluminum and carbon .…”

“…Much attention is devoted to the development of new composites, since they can exhibit the properties unattainable in conventional nonreinforced materials. [1][2][3] Many investigators have studied aluminum matrix composites with carbon reinforcements and possible reaction between aluminum and carbon. [4][5][6][7][8][9][10][11] Nanopowder application in composites enables improvement of a number of key properties; however, the temperature range of such composite application must be studied.…”
