TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.

TL;DR: Findings show that chemical doping is a promising route to achieving high-quality graphene films with a large carrier concentration.

TL;DR: It is shown that different N-bond types, including graphitic, pyridinic, and nitrilic, can exist in a single, dilutely N-doped graphene sheet, indicating that control over the dopant bond type is a crucial requirement in advancing graphene electronics.

TL;DR: Graphene-based, flexible, transparent heaters based on large-scale graphene films synthesized by chemical vapor deposition on Cu foils show sheet resistance as low as ∼43 Ohm/sq with ∼89% optical transmittance, which are ideal as low-voltage transparentheaters.

TL;DR: Lee et al. as mentioned in this paper used nanoscale spherical lenses that self-assemble by bottom-up integration of cup-shaped organic molecules called calixarenes to obtain near-field features of the order of 200 nm.
