Advanced Healthcare Materials, EarlyView.Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Advanced Healthcare Materials, EarlyView.This study reports a novel strategy for preparing a biocompatible adhesive hydrogel crosslinked with a muscle tissue‐derived extracellular matrix (MEM) for in situ muscle regeneration. As a natural crosslinker, MEM not only mediates combinatorial polymer networks but also stimulates satellite cells to induce a cell‐free therapeutic solution.

Efficient, rapid one-electron photooxidation of chemisorbed polyhydroxyl alcohols and carbohydrates by TiO2 nanoparticles in an aqueous solution [PDF]
arXiv, 2004 Time-resolved transient absorption spectroscopy has been used to study nanosecond and sub-microsecond electron dynamics in aqueous anatase nanoparticles in the presence of hole scavengers: chemisorbed polyols and carbohydrates. These polyhydroxylated compounds are rapidly oxidized by the holes; 50-60% of these holes are scavenged within the duration of

A complete study of electroactive polymers for energy scavenging: modelling and experiments [PDF]
Dans Symposium on Design, Test, Integration and Packaging of
MEMS/MOEMS - DTIP 2007, Stresa, lago Maggiore : Italie (2007), 2008 Recent progresses in ultra low power microelectronics propelled the development of several microsensors and particularly the self powered microsystems (SPMS). One of their limitations is their size and their autonomy due to short lifetime of the batteries available on the market. To ensure their ecological energetic autonomy, a promising alternative is

Advanced Healthcare Materials, EarlyView.A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...
