New catalyst material achieves double the DOE fuel cell lifetime target

A UCLA-led team, including Professor Xiangfeng Duan and Dr. Bosi Peng, has developed an ultrafine platinum nanocatalyst embedded with cobalt oxide clusters, significantly enhancing fuel cell efficiency and durability by reducing platinum dissolution. This new catalyst, designed by UCLA materials scientists and chemists, nearly doubles the projected lifetime target set by the U.S. Department of […]

Research sheds light on universal mechanisms of work hardening

Scientists from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have, for the first time, observed the detailed mechanisms of work hardening, a process discovered by early blacksmiths in the Bronze and Iron Ages that strengthens metal through deformation. This research, conducted at the Harvard Materials Research Science and Engineering Center […]

Molecular simulations, supercomputing lead to energy-saving biomaterials breakthrough

A team of scientists at the Department of Energy’s Oak Ridge National Laboratory has developed a new method to process nanocellulose, a plant-based material, reducing energy needs by 21%. This method, discovered through molecular simulations and pilot testing, uses a solvent of sodium hydroxide and urea in water, significantly lowering production costs of nanocellulosic fiber, […]

Scientists find new way to make efficient perovskite LEDs

A research team led by Tae-Woo Lee from Seoul National University’s Department of Materials Science and Engineering, in collaboration with Andrew M. Rappe from the University of Pennsylvania and Omer Yaffe from the Weizmann Institute of Science in Israel, has developed an ultra-high efficiency perovskite nanocrystal LED by strengthening the perovskite lattice and suppressing the […]
