TL;DR: It is demonstrated that large area, high-quality graphene with controllable thickness can be grown from different solid carbon sources—such as polymer films or small molecules—deposited on a metal catalyst substrate at temperatures as low as 800 °C.

TL;DR: The high-performance electrochemical properties of graphene/carbon nanotube/graphene junctions at the interface of the differing carbon allotropic forms can provide more compact ac filtering units and discrete power sources in future electronic devices.

TL;DR: This work should provide clear guidelines for the large-scale synthesis of wafer-scale single-crystal graphene, which is essential for the optimized graphene device fabrication.

TL;DR: Using aberration-corrected scanning transmission electron microscopy, the covalent transformation of sp(2) carbon between the planar graphene and the single-walled carbon nanotubes at the atomic resolution level is observed, providing a new benchmark for understanding the three-dimensional graphene/single-walling carbon Nanotube-conjoined materials.

TL;DR: A superior lithium and sodium storage performance is derived from the well-designed hierarchical hollow ball-in-ball structure of NiO/Ni/Graphene composites, which not only mitigates the volume expansion of Ni O during the cycles but also provides a continuous highly conductive graphene matrix to facilitate the fast charge transfer and form a stable SEI layer.
