Following ultrafast magnetization dynamics in depth

The future development of functional magnetic devices based on ultrafast optical manipulation of spins requires an understanding of the depth-dependent spin dynamics across the interfaces of complex magnetic heterostructures. A novel technique to obtai…

Sniffing out your identity with breath biometrics

Researchers have developed an artificial ‘nose’ that can identify individuals from their breath. Built with a 16-channel sensor array that can detect different compounds found in a person’s breath, the olfactory sensor system has the potential to becom…
