The discovery could help fine-tune nanoparticle alloys for specific uses. Gold-silver alloys are useful catalysts that degrade environmental pollutants, facilitate the production of plastics and chemicals, and kill bacteria on surfaces, among other applications. In nanoparticle form, these alloys could be useful as optical sensors or to catalyze hydrogen evolution reactions. The team, from Rice University and the University of Duisburg-Essen in Germany, employed sophisticated microscopy to show...

New Discovery Could Help Fine-Tune Nanoparticle Alloys for Specific Uses Written by AZoNanoApr 23 2021 Theres gold in them thar nanoparticles, and there used to be a lot of silver, too. But much of the silver has leached away, and researchers want to know how. Gold-silver alloys are useful catalysts that degrade environmental pollutants, facilitate the production of plastics and chemicals and kill bacteria on surfaces, among other applications. In nanoparticle form, these alloys could be useful...

Our NanoNews Digest Sponsors Home > Press > Silver ions hurry up, then wait as they disperse: Rice chemists show ions’ staged release from gold-silver nanoparticles could be useful property Chemists at Rice University and the University of Duisburg-Essen, Germany quantified the release of silver ions from gold-silver nanoparticle alloys. At top, transmission electron microscope images show the change in color as silver (in blue) leaches out of a nanoparticle over several hours, leaving gold at...
