In this study, active-passive filling friction stir repairing (A-PFFSR) process was employed to repair the volume defects in friction stir welding (FSW) joints of Al-Cu alloy. The volume defects with ...

Lead halide perovskites can be turned into optoelectronic devices through low-cost solution depositions, but these approaches often leave numerous charge-trapping defects in the perovskite.

ALBANY, N.Y.--(BUSINESS WIRE)--SEMATECH announced today that researchers have reached a significant milestone in reducing tool-generated defects from multi-layer deposition of mask blanks used for ...

MEMS devices are built with semiconductor equipment. But their failure mechanisms and reliability concerns are completely different from those of ICs. One major concern with MEMs is stiction, or the ...

Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...

A research team led by Jiang Ma from Shenzhen University, China, has developed a novel technique to enhance the plasticity of metallic glasses. By leveraging a combination of controlled aging ...

Scientists are using fleeting antimatter particles to pinpoint tiny defects in metals, ceramics, and semiconductors. Findings from this spectroscopic technique could shape the next generation of ...
