Researchers from NUS have pioneered a photocatalytic atom-swapping transformation that converts oxetanes into a variety of four-membered saturated cyclic molecules, which are key scaffolds in ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

So-called “unlearning” techniques are used to make a generative AI model forget specific and undesirable info it picked up from training data, like sensitive private data or copyrighted material. But ...

This artistic rendering shows a way to make materials atom-by-atom. The electron beam ejects a carbon atom from graphene, and a different atom bonds at the vacancy. Disclaimer: AAAS and EurekAlert!
