Solution-processedfew-layer graphene flakes, dispensed to rotatingand sliding contacts via liquid dispersions, are gaining increasingattention as friction modifiers to achieve low friction and wear attechnologically relevant interfaces. Vanishing friction states, i.e.,superlubricity, have been documented for nearly-ideal nanoscale...

The binary GdNi adopting the orthorhombic CrB-type (oS8, Cmcm) dissolves up to 21 at% Co (GdCo0.42Ni0.58), but when the Co content reaches 23.7 at% the crystal structure of the GdCoxNi1−x phase changes from the orthorhombic CrB-type to the tetragonal MoB-type (tI16, I41/amd). The latter remains stable between 23.7 and 36.0 at% Co (0.47 ≤ xCo ≤...

ABSTRACT: The formation and crystal structure of the binary Cu3As phase have been re-investigated. Some physical properties were then measured on both single crystal and polycrystalline bulk. Cu3As melts congruently at 835 C. At room temperature (RT), this compound has been found to crystallize in the hexagonal Cu3P prototype (hP24, P63cm) with...

Iron-based superconductors are under study for their potential for high-field applications due to their excellent superconducting properties such as low structural anisotropy, large upper critical fields and low field dependence of the critical current density. Between them, Fe(Se,Te) is simple to be synthesized and can be fabricated as a...
