Scientists have enlisted the exotic properties of graphene to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields. They hope to enlist the new method to image electrical signaling networks in our hearts and brains.
Researchers at Lawrence Berkeley National Laboratory have published a new study that, for the first time, explicitly quantifies the thermodynamic scale of metastability for almost 30,000 known materials. This paves the way for designing and making promising next-generation materials for use in everything from semiconductors to pharmaceuticals to steels.
A proposed upgrade to the Advanced Light Source—which would provide new views of materials and chemistry at the nanoscale with X-ray beams up to 1,000 times brighter than possible now—has cleared the first step in a Department of Energy approval process. The upgrade would enable new explorations of chemical reactions, battery performance, and biological processes.
Scientists at Berkeley Lab and Cornell University have successfully paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures. The achievement could open doors to ultra low-power microprocessors, storage devices and next-generation electronics.
Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from Lawrence Berkeley National Laboratory has found an exception: scientists have determined that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.
