  • Previous demonstrations of long-range supercurrents through magnetic materials were achieved only at liquid helium temperatures. Now, using specially tailored samples, long-distance supercurrents have been realized at temperatures as high as 40 K.

  • Epitaxial growth followed by topotactic reduction yields superconducting nickelate phases with the same hole-doping level as that obtained by chemical substitution, without causing structural disorder.

  • Glass-forming ability in metallic systems is related to the diversity of atomic packing schemes quenched into the glassy state, which manifests itself in the width of the first broad X-ray diffraction peak. This provides a swift way for screening libraries of deposited alloy films and searching for good glass formers.

  • Heterogeneous microscale contacts between molybdenum disulfide and graphene or hexagonal boron nitride layers demonstrate ultralow friction independent of their relative orientation with residual drag that originates from edge effects.

  • A double-layer borophene — a boron analogue of the double-layer graphene — has been synthesized, expanding the phase space and potential applications of two-dimensional boron.

  • Integration of memristors in a chain of nano-constriction spintronic oscillators allows for individual control of oscillation frequencies and emerging synchronization patterns. The control of such synchronization could enable learning through association like neurons in the brain.
