Here, the authors report a polymer-free transfer method to fabricate suspended 2D materials with high intactness and thermal conductivity, facilitating the application of graphene grids for high-resolution electron microscopy.
Chemical vapor deposition (CVD) of graphene on widely used insulators can promote its application for functional composite materials. Here, the authors report the large-scale production of graphene alumina fibers/fabrics via a metalloid-catalytic CVD growth process on commercial alumina, showing their application for electrical heating and electromagnetic shielding.
Through precise adjustments to the curvature gradient inherent in stacked graphene assembly walls, a highly controllable water casting process for self-shaping with an accuracy of ca. 10 μm is demonstrated for making shaped functional materials.
Cheng Yang and co-workers develop a “popcorn-making-mimic” strategy to fabricate a uniformly compounded graphene@NiFe2O4 composite film with strong electromagnetic interference shielding and absorption capability.
A strong and tough human muscle-like actuator fibre is developed by exploiting 2D graphene fillers within a liquid crystalline elastomer matrix. Reversible percolation of the graphene filler network endows the artificial muscle with a work capacity and power density beyond those of human or mammalian muscles.
An article in Communications Engineering reports the upcycling of waste plastics from vehicles into graphene that can be then used as an additive in foams for cars.
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.
Bending of few-layer graphene leads to interlayer slip, and slipping lowers the bending stiffness. Beyond a critical bending angle, the graphene layers bend like a stack of paper, with a state of superlubricity for interlayer slip.
