Professor Paul Weiss and James Hohman have devised a facile route to synthesize designer gallium-based alloy microscale and nanoscale materials with precise elemental ratios and excellent uniformity.

Alloy nanoparticle synthesis is typically very challenging and traditional synthetic approaches suffer from elemental incompatibility, the need to use costly vacuum technologies, and limitations of composition range and product uniformity. In this technology, UCLA researchers demonstrate directed particle formation by molecular self-assembly assisted by sonication. The method is solution based and avoids the use of costly vacuum deposition technology while giving gallium-based nanoparticles with excellent uniformity. The technology has wide applications for catalysts, solar cells, and semiconductor components such as high brightness LEDs for displays.
