Efficient PET-RAFT polymerization achieved by using low-toxicity shortwave infrared CuInSe₂/CuInS₂ quantum dots Photoinduced electron/energy transfer reversible addition-fragmentation chain-transfer (PET-RAFT) polymerization enables precise light-controlled polymer growth. Traditional near-infrared strategies often rely on nonlinear optical processes such as two-photon absorption or photon upconversion, which typically require high-intensity laser excitation.

Water reveals superpowers hidden at the nanoscale Researchers at The University of Manchester have made an unexpected discovery about one of the world's most familiar substances—water. When confined to spaces a few atoms thick, water transforms into something completely unfamiliar, exhibiting properties more commonly associated with advanced materials like ferroelectrics and superionic liquids.
