Experimental
Sample preparation a) Single crystals of MoS 2Natural and synthetic crystals of MoS 2 were purchased from 2D semiconductors (El Cerrito, CA, USA) and Structure Probe Inc. (West Chester, PA). The doping and impurities of the purchased crystals were not known. To obtain crystals of uniform quality and doping, n-doped MoS 2 single crystals were synthesized in our laboratory by a chemical-vapor transport (CVT) technique.
Palladium(II)-catalyzed aerobic oxidative cyclization of alkenes with tethered tert-butanesulfinamides furnishes enantiopure 2,5-disubstituted pyrrolidines, originating from readily available and easily diversified starting materials. These reactions are the first reported examples of metal-catalyzed addition of sulfinamide nucleophiles to alkenes.
Atomic layer deposition (ALD) on mechanically exfoliated 2D layered materials spontaneously produces network patterns of metal oxide nanoparticles in triangular and linear deposits on the basal surface. The network patterns formed under a range of ALD conditions, and were independent of the orientation of the substrate in the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
