Since a graphene sheet consists of unsaturated sp2 carbon bonds, the addition reaction for the saturating aromatic bonds can lead to a variety of non-natural two-dimensional (2D) materials. However, despite many interests and numerous efforts, it has not been possible to synthesize a noble stoichiometric 2D crystal by chemically modifying a graphene sheet at large scale, because the prerequisite process, the highly-ordered functionalization on graphene still remains a challenging task. Here, we report a chemical route to synthesize centimeter-scale stoichiometric 'graphenol (C6OH)', 2D crystalline alcohol via vapor phase hydroxylation of epitaxial graphene on Cu(111). Atomic resolution scanning tunneling microscopy revealed this highly-ordered configuration of graphenol and low energy electron diffraction studies on a large-area single crystal graphene film demonstrated the feasibility of the same superstructure being achieved at the centimeter length scale.

The study evaluates whether the introduction of e-alcohol therapy (alcohol therapy delivered via video conference) can break with some of the barriers related to alcohol treatment and ther...
A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses.

A preconceived judgment made without adequate evidence and not easily alterable by presentation of contrary evidence.
Substances interfering with the metabolism of ethyl alcohol, causing unpleasant side effects thought to discourage the drinking of alcoholic beverages. Alcohol deterrents are used in the treatment of alcoholism.
A subjective psychometric response scale used to measure distinct behavioral or physiological phenomena based on linear numerical gradient or yes/no alternatives.
