en.Wedoany.com Reported - German Karlsruhe Institute of Technology (KIT) chemist Professor Claus Feldmann has successfully combined metals that were previously immiscible by using metal nanoparticles as a medium, opening a new path for the development of novel alloys. The German Research Foundation (DFG) has designated his project as a Reinhart Koselleck project, providing €750,000 in funding over five years to support this highly innovative and high-risk research.

Professor Oliver Kraft, Vice President for Research, Teaching, and Academic Affairs at KIT, stated: "Metallic materials are the foundation of many future technologies. Through his nanoparticle research, Feldmann has laid the groundwork for entirely new alloys." Feldmann's research team focuses on using rapid reduction reactions to forcibly mix metal atoms in a liquid phase near room temperature, ensuring their uniform distribution within nanoparticles. This chemical reaction lasts less than a second, thereby preventing the metals from separating.

Feldmann explained that combinations of metals with different properties, such as light metals and hard metals, were previously difficult to achieve, but nanoparticle technology holds the promise of solving this problem. The team's preliminary work has already successfully yielded a variety of previously unsynthesizable bimetallic materials, which exhibit unique properties in terms of reactivity, crystallization, and thermal behavior. In the future, this technology could drive advancements in metallic glasses, catalysts, and high-entropy materials. The project is scheduled to officially launch on June 1, 2026.
