Graphene-based biosensors for detection of bacteria and their metabolic activities
Graphene, which is a recently discovered single-atom-thick planar sheet of carbon atoms perfectly arranged in a honeycomb lattice, has great potential in biosensing owing to its extraordinary electrical, physical, ...
Band-gap manipulations of monolayer graphene by phenyl radical adsorptions : a density functional theory study
Phenyl radical (Ph.) adsorption on monolayer graphene sheets is used to investigate the band-gap manipulation of graphene through density functional theory. Adsorption of a single Ph. on graphene breaks the aromatic π-bond ...
Systematic bandgap engineering of graphene quantum dots and applications for photocatalytic water splitting and Co2 reduction
Graphene quantum dots (GQDs), which is the latest addition to the nanocarbon material family, promise a wide spectrum of applications. Herein, we demonstrate two different functionalization strategies to systematically ...
Heteroatom-doped graphene materials: syntheses, properties and applications
Heteroatom doping can endow graphene with various new or improved electromagnetic, physicochemical, optical, and structural properties. This greatly extends the arsenal of graphene materials and their potential for a ...
