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 ...

Quantum sensor can detect electromagnetic signals of any frequency

Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting ...

High-speed photos shine a light on how metals fail

How things deform and break is important for engineers, as it helps them choose and design what materials they're going to use for building things. Researchers at Aalto University and Tampere University have stretched metal ...

Self-healing material can build itself from carbon in the air

A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective ...
