(Phys.org) —In a move that would make the Alchemists of King Arthur's time green with envy, scientists have unraveled the formula for turning liquid cement into liquid metal. This makes cement a semi-conductor and opens ...

In some circles, memristors (from "memory resistor," as coined by Leon Chua in a 1971 paper outlining memristive theory) are all the rage – and for good reason: As circuit elements which "remember" the amount of current ...
(PhysOrg.com) -- "If you open up almost any electronic gadget, you will see various elements that operating using electric circuitries," Nader Engheta tells PhysOrg.com. "Many of them have different functionalities, such ...
The ability to hide an arbitrary object with a cloak at a distance from the object is a unique task in photonics research, although the phenomenon is yet to be realized in practice. In a recent study now published in Light: ...
(Phys.org) -- Engineers from several research organizations working together in Japan have developed a working prototype of a Mott transistor, a possible alternative to the standard silicon based field-effect transistor (FET). ...
Researchers from the London Centre for Nanotechnology have made new compact, high-value resistors for nanoscale quantum circuits. The resistors could speed the development of quantum devices for computing and fundamental ...
