Dihydrogen monoxide parody oxygen atom. Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix "" in "dihydrogen" means "two", the prefix "" in "monoxide" means "one", and an oxide is an oxygen atom attached to another atom in an ionic compound. Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include "hydrogen oxide", as well as an alkali name of "hydrogen hydroxide", and several acid names such as "hydric acid", "hydroxic acid", "hydroxyl acid", and "hydroxilic acid". The term "hydroxyl acid" used in the original text
Graphite oxide obtained. Reduction of this almost intact graphene oxide performs much better and the mobility values of charge carriers exceeds 1000 cm/Vs for the best quality of flakes. Inspection with the atomic force microscope shows that the oxygen bonds distort the carbon layer, creating a pronounced intrinsic roughness in the oxide layers which persists after reduction. These defects also show up in Raman spectra of graphene oxide. Large amounts of graphene sheets may also be produced through thermal methods. For example, in 2006 a method was discovered that simultaneously exfoliates and reduces graphite oxide by rapid heating (>2000 °C/min) to 1050
