A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

A material built to tell left-handed light from right-handed light has long had a frustrating weakness. It mostly ignored ...

Chiral molecules have structures that cannot be superimposed on their mirror image, like left and right hands. Many ...

A dopant molecule accepts electrons from a chiral perovskite host, enabling visible light absorption while preserving the ...

Scientists have developed a new type of semiconductor material that can do something unusual: it can tell the difference ...

For decades, laser engineers have wrestled with an embarrassing blind spot: the green-through-yellow slice of the visible spectrum, roughly 532 to 633 nanometers, where compact semiconductor lasers ...

A University at Buffalo-led team has found a way to help chiral semiconductors (electronic materials whose structures are ...

Physics Colloquium Date: Tuesday, Sept. 23, 2025 Time: 4– 5 p.m. Location: Olsen 503 Supriya Chakrabarti, Distinguished University Professor, Department of Physics and Applied Physics, University of ...

One way that chemists recycle CO 2 into valuable products is through a process called electrochemical reduction, where a stream of CO 2 gas moves through an electrolysis cell that breaks the CO 2 and ...

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic ...

By harnessing the unique properties of tantala (tantalum pentoxide), a team of US-based researchers has created a photonic integrated circuit that can be tuned to deliver laser light across a broad ...
