A new type of LED light could bring significant efficiency gains

Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling ...

Heat has a memory—and a new theoretical framework can track it

Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...

Trapped light generates nanoscale magnetization

Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...

Physicists take Hall effect in a new direction

Carnegie Mellon University scientists have uncovered a new phenomenon that challenges a longstanding assumption about how electronic materials respond to magnetic fields. The discovery broadens the fundamental understanding ...

High magnetic fields revive superconductivity in nickelates

Scientists from the National University of Singapore (NUS), in collaboration with Los Alamos National Laboratory in the United States, have uncovered that a class of nickel-based materials known as samarium (Sm)-based infinite-layer ...
