A magnetic exchange field confined within graphene and higher than 14 T, an enhancement of the spin generation, and a ferromagnetic ground state are found in the graphene/EuS heterostructure—a model of a 2D-material/magnetic-insulator system.
Geometric frustration selects the equilibrium morphology of cohesive bundles of chiral filaments by controlling the relative costs of filament bending and the straining of the cohesive bonds.
The transition from superlubricity to stick–slip behaviour of a chain of atoms on a periodic surface has now been directly studied experimentally, related to the Aubry transition.
Photocatalytic water splitting using semiconductors is attractive for converting solar energy into hydrogen. An efficient and scalable system based on particulate photocatalyst sheets is now shown to exhibit energy conversion efficiency exceeding 1%.
Experimental findings show that the resonant phonon scattering mechanism proposed by Adamenko and Fuks in 1971, comes into play regarding thermal transport at interfaces, when the surface roughness is comparable to phonon wavelengths.
Generation of stable skyrmion lattices and displacement of trains of individual skyrmions along a magnetic racetrack by short current pulses are demonstrated at room temperature in ultrathin metallic ferromagnets.
Disordering in complex oxides is important for their radiation resistance. It is now shown that pyrochlores disorder by the formation of a weberite-like phase, with similar behaviour observed in spinels, adding complexity to their disordering.
Helium-3 spin-echo measurements and modelling of admolecule–substrate interactions through force field schemes are used to investigate the diffusion and rotation of pentacene admolecules on a pentacene monolayer at room temperature.
Here the authors show that nanocrystals of hafnium oxide can be applied as stable catalytic materials using a dynamic ligand-exchange reaction mechanism.
Polyelectrolyte complexation triggered by solvent exchange enables robust underwater contact adhesion for plastics, glasses, metals and other surfaces.
