Molecular design and light can control electron spin, resulting in fast orientation of the spin direction relative to an applied magnetic field. Controlling the orientation of a single unpaired ...

Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather ...

The body is under constant attack from oxidative stress. Oxygen in the body splits into single atoms with unpaired electrons. Electrons like to be in pairs, so these atoms, called free radicals, ...
