Researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. • Email to a friend • Researchers reveal the material components - and their nano- and microscale blueprints - that make the diabolical ironclad beetle so indestructible, while also demonstrating how engineers can benefit from these designs. • Email to a friend • Researchers have invented a new way to deposit thin layers of atoms as a coating onto a substrate material at near room temperatures. • Email to a friend • A researcher is testing new ways to spin liquid crystals into fibers that could be used in camouflage clothing or to create cleaning wipes that can detect the presence of bacteria. • Email to a friend • Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is one member of a suite of electrical characterization methods available in atomic force microscopes. It maps the contact potential difference between a surface and the cantilever, containing information about the surface potential and work function. KPFM is a surface-sensitive method that probes at and near the surface only. It is often used as a qualitative technique to obtain contrast based on the surface potential. • Email to a friend • Researchers are taking cues from nature to develop 3D photodetectors for biomedical imaging. The team used some architectural features from spider webs and combined it with organic-dye-sensitized graphene hybrid composites to develop the technology. • Email to a friend • Could a stack of 2D materials allow for supercurrents at ground-breakingly warm temperatures, easily achievable in the household kitchen? An international study opens a new route to high-temperature supercurrents at temperatures as 'warm' as inside a kitchen fridge. • Email to a friend • |
