Ion permeation and selectivity of graphene oxide membranes with sub-nm channels dramatically alters with the change in interlayer distance due to dehydration effects whereas permeation of water molecules remains largely unaffected.
Soft phononic clamping dilutes the intrinsic dissipation of a mechanical resonator's material by five orders of magnitude, enabling a record value of the product between frequency and quality factor at room temperature, and mechanical coherence times otherwise only available in optical or Paul traps.
Graphene is being investigated as a candidate material for post-silicon electronics. This article reviews the properties of graphene that are relevant to transistors, and discusses the trade-offs between them.

Highly bioactive supramolecular nanostructures displaying sulfated glycopeptides on their surfaces were designed in order to mimic the polysaccharides that bind and activate a plethora of proteins in mammalian biology during development and tissue regeneration.

Ruthenium nanoparticles homogeneously dispersed in a nitrogenated, two-dimensional carbon matrix show high turnover frequency and small overpotential for hydrogen evolution reaction both in acidic and alkaline media.
Air-stable, non-encapsulated Bi2O2Se ultrathin films grown by chemical vapour deposition display high electron mobility and exceptional semiconducting transport properties, making the observation of quantum oscillations possible and suggesting potential applications in electronics.
Applying high-potential alternating current to a carbon-nanotube–polymer composite film provides a self-heating membrane that enhances desalination performance of high-salinity brines by membrane distillation.
