Crossover sound: Unambiguous evidence for coherent phonons in superlattices
We all learn in high school science about the dual nature of light - that it exists as both waves and quantum particles called photons. It is this duality of light that enables the coherent transport of photons ...
Ballistic transport in graphene suggests new type of electronic device
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room ...

Dislocations in oxides seen as promising electrolytes create a 'traffic jam' for charged ions
Dislocations in oxides such as cerium dioxide, a solid electrolyte for fuel cells, turn out to have a property that is the opposite of what researchers had expected, according to a new analysis at MIT.
Companies increasingly turn to tech to keep drones out of no-fly zones
Low-cost hobby drones are making the power of flight accessible to anyone with a few hundred bucks to spare. But a combination of technology and safety laws could take the controls out of users' hands.
Semiconductor works better when hitched to graphene
Graphene – a one-atom-thick sheet of carbon with highly desirable electrical properties, flexibility and strength – shows great promise for future electronics, advanced solar cells, protective coatings ...
Researchers identify key hormone-transporting protein for plant fertility
Researchers at Tokyo Institute of Technology have identified a transporter protein at the heart of a number of plant processes associated with fertility and possibly aging.
