Pseudospin-driven spin relaxation mechanism in graphene

Scientists unveiled an unprecedented spin relaxation mechanism unique to graphene, and related with entanglement of spin and pseudospin quantum degrees of freedom in presence of weak spin-orbit coupling effects. This phenomenon revisits years of controversies and opens a new window into the challenge of manipulating spin degree of freedom in future information-processing technologies.

Unravelling the mysteries of topological heat transport

Researchers have determined the microscopic origin of an unusual form of magnetic heat transport. The team reports on how magnetic 'quasi-particles', known as magnons, propagate in Lu2V2O7, the first material to exhibit the thermal magnon Hall effect: the magnetic transport of heat perpendicular to a temperature gradient.

Engineers improve strength and flexibility of atom-thick films

Researchers have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration and radiofrequency shielding in technology from portable electronics to coaxial cables.

A greasy way to take better protein snapshots

The dream of analyzing the structure of large, hard-to-crystallize proteins and other bio molecules has come one step closer to reality. In new study, researchers used a newly developed grease to suspend small crystals of lysozyme, glucose isomerase, thaumatin, and fatty acid-binding protein type-3, which they then analyzed using the revolutionary serial femtosecond crystallography method.
