Proteins imaged in graphene liquid cell have higher radiation tolerance

By preparing a microtubule sample in a graphene liquid cell, researchers demonstrate that the radiation tolerance of proteins proteins in liquid-phase electron microscopy is increased by an order of magnitude compared to a sample in ice.

New traffic rules in ‘Graphene City’

In the drive to find new ways to extend electronics beyond the use of silicon, physicists are experimenting with other properties of electrons, beyond charge. Physicists now describe a way to manipulate electrons based on their energy in relation to momentum — called ‘valley degree of freedom.’

Molecular adlayer produced by dissolving water-insoluble graphene in water

Using ‘molecular containers’ that encapsulate water-insoluble molecules, researchers developed a formation procedure for a nanographene adlayer, a layer that chemically interacts with the underlying substance, by just mixing the molecular containers and nanographene together in water.

Photonic crystals for nano-light in moire graphene superlattices

Graphene is an atomically thin plasmonic medium that supports highly confined plasmon polaritons, or nano-light, with very low loss. Electronic properties of graphene can be drastically altered when it is laid upon another graphene layer, resulting in a moiré superlattice. The relative twist angle between the two layers is a key tuning parameter of the interlayer coupling in thus-obtained twisted bilayer graphene (TBG). We studied the propagation of plasmon polaritons in TBG by infrared nano-imaging. We discovered that the atomic reconstruction occurring at small twist angles transforms the TBG into a natural plasmon photonic crystal for propagating nano-light. This discovery points to a pathway for controlling nano-light by exploiting quantum properties of graphene and other atomically layered van der Waals materials, eliminating the need for arduous top-down nanofabrication.
