To celebrate the tenth anniversary of Nano Letters, this short commentary discusses a scientific issue of current interest, increased electron-electron interactions in nanostructures. The two major factors of reduced dimensionality and low screening are analyzed. Carbon nanotubes and graphene are molecular in many of their properties and show strong electron-electron interactions. In specific c...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
