New all-optical imaging technique with an unprecedented frame rate allows scientists to visualize ultrafast transient phenomena. • Email to a friend • Automatic approach could enable precision fabrication of optical components and multimaterial structures. • Email to a friend • Researchers demonstrate a highly flexible but sturdy wearable piezoelectric harvester using the simple and easy fabrication process of hot pressing and tape casting. • Email to a friend • Researchers have tested whether gold nanoparticles could be toxic to cells, finding how they affect lipid membranes depends on their size. • Email to a friend • Researchers have created a smart drug delivery system that reduces inflammation in damaged nervous tissues and may help treat spinal cord injuries and other neurological disorders. • Email to a friend • Scientists show that high-resolution movies of molecular dynamics can be recorded using electrons ejected from the molecule by an intense laser field. • Email to a friend • Researchers have discovered that colloidal rods can be moved on a chip quickly, precisely, and in different directions, almost like chess pieces. A pre-programmed magnetic field even enables these controlled movements to occur simultaneously. • Email to a friend • With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging. • Email to a friend • A major challenge for nanophotonics engineers is the wide range of optical responses that metamaterials and other nanoplasmonic structures can generate. In the past few years, machine learning has emerged as a powerful tool for sifting through this vast universe of possible design parameters to aid the design of nanophotonic devices tailored for specific applications. A novel approach uses a type of neural network called a mixture density network to solve the non-uniqueness problem of machine learning algorithms, while also improving accuracy. • Email to a friend • Adding calcium to graphene creates an extremely promising superconductor, but where does the calcium go? In a new study, researchers have for the first time confirmed what actually happens to those calcium atoms. • Email to a friend • |
