To realize graphene-based electronics, various types of graphene are required; thus, modulation
of its electrical properties is of great importance. Theoretic studies show that intentional …

Background The China Mental Health Survey was set up in 2012 to do a nationally representative
survey with consistent methodology to investigate the prevalence of mental disorders …

The optical conductance of monolayer graphene is defined solely by the fine structure constant,
α = $e^2 /\hbar c$ (where e is the electron charge, $\hbar $ is Dirac's constant and c is …
