Abstract:
Glassy materials play an integral role in the modern world, but inherent brittleness has long been the Achilles heel that severely limits their usefulness. Due to the disordered amorphous structure of glassy materials, many mysteries remain. These include the fracture mechanisms of traditional glasses, such as silicate glasses, as well as the origin of the intriguing patterned fracture morphologies of metallic glasses.
Scientists observe role of cavitation in glass fracturing
Beijing, China | Posted on April 2nd, 2021
Dr. SHEN Laiquan, Prof. BAI Haiyang, Prof. SUN Baoan, and others from Prof. WANG Weihua s group at the Institute of Physics of the Chinese Academy of Sciences (CAS) have successfully observed the effect of cavitation on fracture behavior in glasses. They revealed that crack propagation is dominated by the self-organized nucleation, growth, and coalescence of nanocavities in metallic glasses.

2021 FEB 09 (NewsRx) By a News Reporter-Staff News Editor at Information Technology Daily Investigators publish new report on Information Technology - Data Recovery. According to news reporting originating in Guangzhou, People’s Republic of China, by NewsRx journalists, research stated, “In this paper, we focus on the false data injection attacks (FDIAs) on state estimation and corresponding countermeasures for data recovery in smart grid. Without the information about the topology and parameters of systems, two data-driven attacks (DDAs) with noisy measurements are constructed, which can escape the detection from the residue-based bad data detection (BDD) in state estimator.”
