TL;DR: The fabrication of nanoperforated graphene materials with sub-20-nm features using cylinder-forming diblock copolymer templates across >1 mm(2) areas is demonstrated to facilitate applications of graphene in electronics, optoelectronics, and sensing.

TL;DR: A route to noncovalently latch dipolar molecules on graphene to create stable chromophore/graphene hybrids where molecular transformation can be used as an additional handle to reversibly modulate doping while retaining high mobilities is reported.

TL;DR: The fabrication of a thiol-functionalized cellulose nanofiber membrane that can effectively adsorb heavy metal ions is reported, highlighting the significance of surface functionality on biocompatible, nontoxic, and sustainable cellulose materials to expand their potential and applicability towards water remediation applications.

TL;DR: In this paper, the authors describe the latest advances in synthesis, characterization, and applications of polymer brushes, which meet criteria such as: (i) Efficient and fast grafting, (ii) Applicability on a wide range of substrates; and (iii) Precise control of surface initiator concentration and hence, chain density.

TL;DR: In this paper, the etch mask comprises a pattern-defining block copolymer layer, and can optionally also comprise a wetting layer and a neutral layer, which can be used to define a periodic array of holes over a single sheet of graphene or a plurality of graphene sheets.
