Unveiling the 3D Atomic Structure and Potential of Next-Generation Alloys

Researchers at UCLA have used an advanced imaging technique to map the three-dimensional atomic coordinates of medium- and high-entropy alloys for the first time. By correlating the mixture of elements with structural defects, the team discovered a new way to boost the toughness and flexibility of these alloys. The study provides insights into the design of durable alloys and has the potential to unlock new properties in conventional alloys like steel. The researchers are also developing new imaging methods to further understand the structures and properties of these alloys.

"Exploring High-Entropy Alloys: Revolutionizing Electrocatalysis Research"

A research team has developed a new platform to study and control the atomic-level structure of high-entropy alloys' surfaces, specifically focusing on platinum high-entropy alloys (Pt-HEAs). They found that Pt-HEAs outperformed platinum-cobalt alloys in the oxygen reduction reaction (ORR), indicating that the atomic arrangement and distribution of elements near the surface contribute to their excellent catalytic properties. The team believes that their findings have broad applicability and can be used to advance electrocatalysis and functional nanomaterials.

"Synthesizing Diverse High-Entropy Alloy Nanoparticles with Liquid Metal"

Researchers have developed a new method for synthesizing high-entropy alloy nanoparticles using liquid metal. The method involves mixing the liquid metal with a solution containing the desired metal precursors, which then undergoes a chemical reaction to form the nanoparticles. The resulting nanoparticles have a high degree of compositional complexity and can be used as catalysts in a variety of applications. This new approach offers a promising avenue for the development of high-performance materials with unique properties.

"Multi-Metal Nanoparticles Synthesized with Liquid Metal"

Researchers in China have developed a new technique to create multi-element nanoparticles using liquid gallium as a matrix to combine many other metals that were previously immiscible. The nanoparticles contain an even distribution of 17 different elements, including gallium, iron, nickel, copper, zinc, scandium, vanadium, manganese, magnesium, zirconium, platinum, rhodium, ruthenium, iridium, hafnium, molybdenum, and niobium. These materials could have interesting and tuneable electronic, chemical, and physical properties, making them useful in a wide range of applications.
