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 ...

A new model measures defects that can be leveraged to improve materials' mechanical strength, heat transfer, and ...

A congenital heart defect is a condition you’re born with. Types of heart defects vary in severity — with some, you’ll need surgery as a child, while others don’t need treatment until later in life or ...

Engineers have found a way to simultaneously mitigate three types of defects in parts produced using a prominent additive manufacturing technique called laser powder bed fusion. University of ...

Researchers created a high-resolution 3D ultrasonic imaging system for concrete that uses broadband ultrasonic signals to automatically adapt to different types of concrete structures. WASHINGTON, Jan ...

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how ...

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 ...
