UD-led breakthrough may advance development of mid-infrared light sources, lasers

A research group at the University of Delaware has achieved a breakthrough in the emerging field of “Group IV Semiconductor Optoelectronic Devices.”

The UD research team, led by James Kolodzey, demonstrated that it is possible to use a combination of germanium and tin (GeSn) to create a light emitting diode (LED) that operates in the infrared spectrum, wavelengths invisible to the naked eye. (more…)

UCLA’s New Nano-Lens Microscopes Can Detect Viruses, Other Objects at Nanoscale

By using tiny liquid lenses that self-assemble around microscopic objects, a team from UCLA’s Henry Samueli School of Engineering and Applied Science has created an optical microscopy method that allows users to directly see objects more than 1,000 times smaller than the width of a human hair.

Coupled with computer-based computational reconstruction techniques, this portable and cost-effective platform, which has a wide field of view, can detect individual viruses and nanoparticles, making it potentially useful in the diagnosis of diseases in point-of-care settings or areas where medical resources are limited.
