Lauryldimethylamine oxide 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 "S. aureus" and "E. coli", however it is also non-denaturing and may be used to solubilize proteins. At high concentrations, DDAO forms liquid crystalline phases. Despite having only one polar atom that is able to interact with water – the oxygen atom (the quaternary nitrogen atom is hidden from
Lithium ion manganese oxide battery Lithium ion manganese oxide battery A Lithium ion manganese oxide battery is a lithium ion cell that uses manganese dioxide, , as the primary cathode material. They function through the same intercalation/de-intercalation mechanism as other commercialized secondary battery technologies, such as . They are a promising technology as their manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability. One of the more prominent compounds is , a lithium-manganese-oxide based material with a spinel structure (space group Fd3m). In addition to being a cheap and non-toxic alternative material, the spinel structure of provides a three-dimensional framework for the insertion
