Researchers have developed an ultrafast light-emitting device that can flip on and off 90 billion times a second and could form the basis of optical computing.
Instruments that measure the properties of light, known as spectrometers, are widely used in physical, chemical, and biological research. These devices are usually too large to be portable, but MIT scientists have now shown ...
Nature loves crystals. Salt, snowflakes and quartz are three examples of crystals - materials characterized by the lattice-like arrangement of their atoms and molecules.
A pioneering new technique to produce high-quality, low cost graphene could pave the way for the development of the first truly flexible 'electronic skin', that could be used in robots.
