A novel technique that uses quantum light to measure temperature at the nanoscale

Phys.org   -   Scientific News Websites

Being able to measure, and monitor, temperatures and temperature changes at miniscule scales—inside a cell or in micro and nano-electronic components—has the potential to impact many areas of research from disease detection to a major challenge of...

Bottom-up approach can synthesize microscopic diamonds for bioimaging, quantum computing

Phys.org   -   Scientific News Websites

Scientists are excited about diamonds—not the types that adorn jewelry, but the microscopic variety that are less than the width of a human hair. These so-called "nanodiamonds" are made up almost entirely of carbon. But by introducing ot...

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds: Bound for only ten quadrillionths of a second

ScienceDaily   -   General News Websites

Graphene is an extraordinary material consisting of pure carbon just a single atomic layer thick. It is extremely stable, strong and conductive. In electronics, however, graphene has crucial disadvantages. It cannot be used as a semiconductor, sin...

Monitoring the lifecycle of tiny catalyst nanoparticles: Since they are so tiny, it is difficult to investigate single nanoparticles

ScienceDaily   -   General News Websites

In order to tailor nanoparticles in such a way that they can catalyze certain reactions selectively and efficiently, researchers need to determine the properties of single particles as precisely as possible. So far, an ensemble of many nanoparticl...
