Temperature effect on the synthesis of Au-Pt bimetallic nanoparticles
Article Abstract:
Pt-Au bimetallic nanoparticles are synthesized by the polyol method and stabilized with poly(vinylpyrrolidone), modifying the temperature of synthesis. It was observed that at lower temperatures no bimetallic nanoparticles were detected but as the temperature increased bimetallic nanoparticles started to appear, commonly obtaining core-shell nanoparticles, always covered by the polymer.

Resistance changes due to thermal coalescence in colloidal Au/organic linker molecule multiplayer films
Article Abstract:
A dramatic change in resistance of nearly six orders of magnitude was observed upon heating gold films fabricated on flexible polymer substrates by a layer-by-layer assembly process using organic linker molecules. This decrease in the resistance depends on the temperature and is faster at higher temperatures.
