Synthesis of a monolayer fullerene network
Using an interlayer bonding cleavage strategy, a two-dimensional monolayer fullerene network is prepared; its moderate bandgap makes it a potential candidate for use in two-dimensional electronic devices.

Single-crystal, large-area, fold-free monolayer graphene
Restricting the initial growth temperatures used for chemical vapour deposition of graphene on metal foils produces optimum conditions for growing large areas of fold-free, single-crystal graphene.

Gram-scale bottom-up flash graphene synthesis
Flash Joule heating of inexpensive carbon sources is used to produce gram-scale quantities of high-quality graphene in under a second, without the need for a furnace, solvents or reactive gases.

Proton-assisted growth of ultra-flat graphene films
A growth process in which protons decouple graphene from the underlying substrate greatly reduces the number of wrinkles that usually degrade large graphene films grown by chemical vapour deposition.

Engineering of robust topological quantum phases in graphene nanoribbons
Graphene nanoribbons are used to design robust nanomaterials with controlled periodic coupling of topological boundary states to create quasi-one-dimensional trivial and non-trivial electronic quantum phases.

Topological band engineering of graphene nanoribbons
A topologically engineered graphene nanoribbon superlattice is presented that hosts a one-dimensional array of half-filled, in-gap localized electronic states, enabling band engineering.

Face-to-face transfer of wafer-scale graphene films
High-quality graphene is grown on copper and then transferred to the underlying substrate, typically silicon oxide or quartz, by simply etching away the copper; the graphene is held in place during etching by capillary bridges.

Growth of graphene from solid carbon sources
The past few years have seen a spectacular growth of interest in graphene. Efforts to produce large sheets of monolayer (or few-layer) graphene could receive a welcome boost from the simple procedure reported by these authors. They show how baking various solid carbon sources (for example polymer films) deposited on a metal catalyst substrate can produce either pristine graphene or doped graphene in a single step.
