Severe Plastic Deformation of 2D Crystallites [PDF]
Universal Journal of Physics and Application, 2013 The kinetics of dislocations is studied by means of computer simulation at different severe loadings. It is found that the dislocations can have a few (at least, two) different structural states. The localized dislocations with core shape as "micropore" play important role in formation of large curved grain boundaries, and, as a consequence, in ...

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization
Advanced Functional Materials, EarlyView.Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Plasma-sprayed coatings for lubrication of a titanium alloy in air at 430 deg C [PDF]
Plasma sprayed coatings of pure silver and of composite materials containing silver were investigated as possible self lubricating coatings for titanium alloys in air at 430 C. Pure silver provided low friction but was prone to severe plastic deformation

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies
Advanced Functional Materials, EarlyView.Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.
