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 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 ...

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 ...

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 ...

These scientists may be close to uncovering how imperfection itself shapes beauty, revealing profound truths hidden within ...

Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the ...

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 ...

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...
