Ultrasensitive sensor using N-doped graphene

A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing ...

Breaking Down the Barrier for Smaller, Faster Electronic Devices

(PhysOrg.com) -- A team of international researchers is the first to uncover the chemical composition and structure of a microelectronics element that is vital to producing ever smaller - and, thus, cheaper and faster - devices.

X-ray study yields new insights on lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries are a relatively new variety of battery being studied and developed by researchers around the world. Because they have very high theoretical energy densities – storing more than five times ...

Bringing measuring accuracy to radical treatment

An international team of scientists working at the Plasma Technology research unit at Ghent University, Belgium, has determined for the first time the absolute density of active substances called radicals found in a state ...

Biology, materials science get a boost from robust imaging tool

Shape and alignment are everything. How nanometer-sized pieces fit together into a whole structure determines how well a living cell or an artificially fabricated device performs. A new method to help understand and predict ...
