The team reported on a new on-chip "tool" that helps to "see" & identify the key process that hinders the performance of catalyst used in fuel cells. The tool will help scientists find respective solutions more efficiently.
The work was led by Xiangfeng Duan, a UCLA professor of chemistry and biochemistry, and Yu Huang, a UCLA professor of materials science and engineering.
The lead author of the study is Mengning Ding (pictured right), a former UCLA CNSI postdoctoral fellow advised by Huang and Duan, now a professor of chemistry at Nanjing University, China. Other study authors are UCLA graduate students and postdoctoral researchers in Duan and Huang’s research groups and researchers from King Saud University, Saudi Arabia.
Chosen from a pool of 286 nominated promising scientific researchers aged 42 years and younger from America’s top academic and research institutions, Duan is one of 11 Physical Sciences & Engineering finalists and Garg is one of ten Chemistry finalists. The finalists were selected based on their extraordinary accomplishments and their promise for the future.
UCLA scientists and engineers have developed a new process for assembling semiconductor devices. The advance could lead to much more energy-efficient transistors for electronics and computer chips, diodes for solar cells and light-emitting diodes, and other semiconductor-based devices.
Thirty UCLA faculty members are among the most influential researchers in their fields for 2017, as determined by Claritive Analytics. The organization compiled its 2017 Highly Cited Researchers list of more than 3,000 scientists from around the world whose studies were among the top 1 percent most referenced in studies from their field.

A research team led by UCLA scientists and engineers has developed a method to make new kinds of artificial “superlattices” — materials comprised of alternating layers of ultra-thin “two-dimensional” sheets, which are only one or a few atoms thick. Unlike current state-of-the art superlattices, in which alternating layers have similar atomic structures, and thus similar electronic properties, these alternating layers can have radically different structures, properties and functions, something not previously available.
