In biology, defects are generally bad. But in materials science, defects can be intentionally tuned to give materials useful new properties. Today, atomic-scale defects are carefully introduced during ...

CAMBRIDGE, Mass.--It's a well-known characteristic of metals that repeated bending in the same place can cause the material to weaken and eventually break; this phenomenon, known as metal fatigue, can ...

image: THE INTRODUCTION OF DEFECTS INTO ELECTRODE MATERIALS FOR METAL-BASED BATTERIES IS AN EFFECTIVE STRATEGY TO IMPROVE BATTERY PERFORMANCE, DUE TO DEFECTIVE CATALYSTS HAVE THE ADVANTAGES OF HIGH ...

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 ...

(Nanowerk News) University of Wisconsin-Madison engineers have found a way to simultaneously mitigate three types of defects in parts produced using a prominent additive manufacturing technique called ...

SAN FRANCISCO — A South Korean researcher has described a new method for detecting extremely low levels of metal particles that often turn into chip defects. Excellent methods of detection exist, ...

Using X-ray beams and machine learning for detecting structural defects, such as pore formation, can help prevent failure of metal 3D-printed parts. Systematic computer-based material design uses ...

Novosibirsk State Technical University has developed an intelligent quality control system for industry. The technology allows you to automatically find cracks, dents, and corrosion spots on a steel ...

The most popular 3D printing process for making metal parts is laser powder-bed fusion (LPBF). It uses a laser beam to scan 2D patterns over a flat bed of powdered metal to form melt tracks that fuse ...
