New chip opens door to AI computing at light speed

University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing ...

Inverted polymer solar cell efficiency sets world record

(Phys.org)—For many years, researchers have strived to reach the goal of 10% efficiency for polymer-based organic photovoltaic (OPV) solar cells, a target widely considered to be the threshold for commercial applications. ...

Nano-LEDs emit full visible spectrum of light

(PhysOrg.com) -- Physicists from Taiwan have designed and fabricated nano-sized light-emitting diodes (LEDs) that emit light spanning the entire visible spectrum. Although the tiny full-color LEDs aren't intended for commercial ...

Wireless power transfer enhanced by metamaterials

(Phys.org)—Over the past decade, research on wireless power transfer has led to the development of several commercial applications, such as wireless charging of mobile devices and electric toothbrushes, as well as wireless ...

Smart material prototype challenges Newton's laws of motion

For more than 10 years, Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, has been investigating the unconventional properties of "metamaterials"—an artificial material that exhibits ...
