Professor Umeno looks into how materials deform and fracture in nano- and microworld with simple computer programs he devises

Researchers from The University of Tokyo Institute of Industrial Science develop an experimentally supported mathematical model that defines the velocity jump mechanism in crack propagation

Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the electrode active site based on microscope observations instead of the simplified and idealized atomic structures employed in previous studies. This better understanding of how the structures in the cells affect the reactions could give clues on ways to improve performance and durability in future devices.
