Dihydrogen monoxide parody story has since been used in science education to encourage critical thinking and discussion of the scientific method. A 1983 April Fools' Day edition of the "Durand Express", a weekly newspaper in Durand, Michigan, reported that "dihydrogen oxide" had been found in the city's water pipes, and warned that it was fatal if inhaled, and could produce blistering vapors. The first appearance of the parody on the Internet was attributed by the "Pittsburgh Post-Gazette" to the so-called "Coalition to Ban Dihydrogen Monoxide", a parody organization at UC Santa Cruz following on-campus postings and newsgroup discussions in 1990.

10-Methacryloyloxydecyl dihydrogen phosphate 10-Methacryloyloxydecyl dihydrogen phosphate MDP Monomer (10-Methacryloyloxydecyl dihydrogen phosphate) is used for dental adhesive materials. The phosphate monomer was developed by Kuraray co., Ltd. with focus on the dental adhesion technology in 1981. 10-MDP MDP is synthesized according to the following reaction. At first, 10-hydroxydecy methacrylate is synthesized by reaction with methacrylic acid and 1,10-decandiol. Next, phosphoryl chloride is added to 10-hydroxydecy methacrylate, then, the bonding of P-Cl is hydrolyzed. In the late 1970s, tooth adhesion phosphate monomer: 2-methacryloyloxethyl phenyl hydrogen phosphate (Phenyl-P) was developed for tooth substance saving restoration technique. 4-Methacryloyloxyethyl trimellitic acid anhydride (4-META) that adhere to not only
