Lauryldimethylamine oxide intermolecular interactions), DDAO is a strongly hydrophilic surfactant: it forms normal micelles and normal liquid crystalline phases. High hydrophilicity of this surfactant can be explained by the fact that it forms very strong hydrogen bonds with water: the energy of DDAO – water hydrogen bond is about 50 kJ/mol. Lauryldimethylamine oxide Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide based nonionic surfactant, with a C (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. Like other amine oxide based surfactants it is antimicrobial, being effective against common bacteria such as
Cerium(III) oxide Cerium(III) oxide Cerium(III) oxide, also known as cerium oxide, cerium trioxide, cerium sesquioxide, cerous oxide or dicerium trioxide, is an oxide of the rare-earth metal cerium. It has chemical formula CeO and is gold-yellow in color. Cerium oxide is used as a catalytic converter for the minimisation of CO emissions in the exhaust gases from motor vehicles. When there is a shortage of oxygen, cerium(IV) oxide is reduced by carbon monoxide to cerium(III) oxide: When there is an oxygen surplus, the process is reversed and cerium(III) oxide is oxidized to cerium(IV) oxide: Major automotive applications for cerium(III) oxide are, as
