Quantum tunneling pushes the limits of self-powered sensors

Shantanu Chakrabartty's laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they've run into a roadblock ...

New laser could upgrade the images in tomorrow's technology

A new semiconductor laser developed at Yale has the potential to significantly improve the imaging quality of the next generation of high-tech microscopes, laser projectors, photolithography, holography, and biomedical imaging.

Tunable antenna could end dropped cell phone calls

(Phys.org) —Why do cell phones drop calls? Like a radio dial tuned to different frequencies (stations), cell phone antennas have tuning circuits that quickly switch frequencies when controlled by a voltage applied to a ...

Guinness record: World's thinnest glass is just two atoms thick

(Phys.org) —At just a molecule thick, it's a new record: The world's thinnest sheet of glass, a serendipitous discovery by scientists at Cornell and Germany's University of Ulm, is recorded for posterity in the Guinness ...
