Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...

Material structures are rarely perfect, but researchers at the Japan Advanced Institute of Science and Technology (JAIST) have now identified a way to make them more so. By monitoring in real time how ...

The formation of lithium dendrites is still a mystery, but materials engineers study the conditions that enable dendrites and how to stop them. Historically, as in decades ago, rechargeable lithium ...

A promising semiconductor material, halide perovskite, could be improved if flaws previously thought irrelevant to performance are reduced, according to new research. A promising semiconductor ...

A study led by University of Oxford and Brookhaven National Laboratory researchers has uncovered how exposure to hydrogen atoms dynamically alters the internal structure of stainless steel. The ...

RAILWAY AGE, JUNE 2023 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic about which professionals in the railway industry have asked to ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...
