From World War II to Somalia, the percentage of casualties caused by landmines has risen sharply. These explosives have indiscriminately killed and wounded soldiers and civilians for over six ...

Nuclear quadrupole resonance spectroscopy is used to map the properties of atomically thin hexagonal boron nitride, with the help of the nitrogen–vacancy colour centres engineered in a diamond ...

Physicists originally tackled this problem with a technique based on ‘nuclear quadrupole resonance’, which detects the nitrogen that most explosives contain. When the explosive is placed in an ...
