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 deposition is done under ambient conditions and can use a wide range of substrates. Langmuir-Blodgett has been suggested to produce films with better quality compared to other methods such as chemical vapor deposition, spin coating or dip coating. Graphene oxide can be further reduced into graphene. Nonlinear optical materials are of great importance for ultrafast photonics and optoelectronics. Recently, the giant optical nonlinearities of graphene oxide (GO) has been proved useful for a number of applications. For example, the optical limiting of GO are indispensable to protect sensitive instruments from laser-induced damage. And the saturable absorption can be used for
