Giant spin polarization and a pair of antiparallel spins in a chiral superconductor
The simultaneous observation of spin–orbit interaction enhancement and chirality represented by a pair of oppositely polarized spins is reported for an organic chiral superconductor in the vicinity of the superconducting transition temperature.

Tracking the ultrafast motion of a single molecule by femtosecond orbital imaging
Watching a single molecule move calls for measurements that combine ultrafast temporal resolution with atomic spatial resolution; this is now shown to be possible by combining scanning tunnelling microscopy with lightwave electronics, through a technique that involves removing a single electron from the highest occupied orbital of a single pentacene molecule in a time window shorter than an oscillation cycle of light.

Approaching disorder-free transport in high-mobility conjugated polymers
Measurements and simulations of several high-mobility conjugated polymers show that their charge transport properties reflect an almost complete lack of disorder in the polymers, despite their amorphous microstructures, resulting from the resilience of the planar polymer backbone conformations to side-chain disorder.
