TL;DR: It is found that evaporation from centimetre-sized carbon black sheets can reliably generate sustained voltages of up to 1 V under ambient conditions.

TL;DR: It is shown that a voltage of a few millivolts can be produced by moving a droplet of sea water or ionic solution over a strip of monolayer graphene under ambient conditions and is illustrated by using it to create a handwriting sensor and an energy-harvesting device.

TL;DR: Key aspects pertaining to water–carbon interactions and basic mechanisms of harvesting water energy with nanostructured materials are discussed and main challenges in improving the energy conversion efficiency and scaling up the output power are analysed.

TL;DR: In this article, the authors studied tunnelling through thin ferromagnetic chromium tribromide (CrBr3) barriers that are sandwiched between graphene electrodes, which could allow two-dimensional spintronic devices to be developed.

TL;DR: A new contact scheme is reported that utilizes cobalt (Co) with a monolayer of hexagonal boron nitride (h-BN) that has the following two functions: modifies the work function of Co and acts as a tunneling barrier, and measures a flat-band Schottky barrier of 16 meV, which makes thin tunnel barriers upon doping the channels, and thus achieves low-T contact resistance of 3 kΩ.
