Core Viewpoint - Researchers at Anhui Normal University have successfully synthesized sub-nanometer high-entropy alloys under mild conditions using laser irradiation, which has broad applicability and can incorporate up to ten metal elements [1][4]. Group 1: Research Methodology - The research team innovatively employed laser irradiation technology to achieve uniform mixing of various metals and successfully produced sub-nanometer-sized high-entropy alloy particles [3]. - The nanosecond pulsed laser rapidly elevated the surface temperature of the particles to over 2000 degrees Celsius and then cooled them at a rate exceeding one billion degrees per second, overcoming the limitations of traditional synthesis methods [4]. Group 2: Implications and Applications - This new laser synthesis method significantly expands the material system and applicability of high-entropy alloys, potentially advancing their practical applications in energy, catalysis, and providing new ideas for material development [4].
