Scientists have invented a new way to probe the valence electrons of atoms deep inside a crystalline solid, using laser light to excite, steer, and bounce the valence electrons off other atoms, giving clues to the material's atomic structure and function.
Researchers have revealed new atomic-scale details about pesky deposits that can stop or slow chemical reactions vital to fuel production and other processes. This disruption to reactions is known as deactivation or poisoning.
The Graphene Flagship, Europe's biggest ever research initiative, carries out advanced research into the creation of unique and innovative materials by incorporating graphene into composites. There are many potential application areas including the aerospace and automotive industries, energy applications, structural foams, films and coatings.
To address the intrinsic limitation of magnetic actuation, a team of researchers has developed a way to use microbubbles to provide the specificity needed to power micro-robots for biomedical applications.
Scientists have calculated a model of an optical system in which large losses in waveguides are compensated by a small gain. The newly discovered phenomenon means that a signal can be transmitted with virtually no losses, which up until now had been an unresolved issue with plasmonic and nanooptic devices.
Researchers have improved the design of tiny nanodiscs - synthetic models of cell membranes used to study proteins that control what enters and leaves a cell. The enhancements provide an unprecedented view of how viruses infect cells.
