Despite the many attractive features of graphene, the lack of atomic bonds between graphene and substrates and among graphene nanosheets has limited its potential applications. Although theoretical considerations predict that covalent bonds between graphene nanosheets would significantly improve s…

LiFeAs compounds, compared to FeAs materials, do not demonstrate spin-density wave behavior and exhibit superconductivity at ambient pressures without chemical doping. However, the current electrochemical methods to prepare pnictide LiFeAs superconductors require a solid-state reaction at high tem…
