TL;DR: The synthesis of ordered, stacked macroscopic three-dimensional solid scaffolds of graphene oxide fabricated via chemical cross-linking of two-dimensional GO building blocks form highly porous interconnected structures, and the controlled reduction of these structures leads to formation of 3D conductive graphene scaffolds.

TL;DR: A versatile platform for a highly efficient and stable graphene oxide (GO)-based optical sensor that exhibits distinctive ratiometric color responses and can be expanded easily to various other multifunctional, GO-based sensors by using alternate stimuli-responsive polymers.

TL;DR: A facile, one-step method for achieving systematic control of the surface properties of highly fluorescent GQDs, which can effectively stabilize oil-in-water Pickering emulsions and submicron-sized colloidal particles in mini-emulsion polymerization and offer great potential for various applications, including fluorescent sensors and imaging.

TL;DR: In this paper, surface properties of GQDs were modified by grafting different alkyl ligands, such as hexylamine and oleylamine, to generate the surfactant behavior of the GQD.

TL;DR: In this paper, the diameter of polystyrene-b-polybutadiene block copolymers (BCPs) can be controlled by tuning the pore diameter of the membrane.
