Trimethylamine N-oxide Trimethylamine N-oxide Trimethylamine "N"-oxide (TMAO) is an organic compound with the formula (CH)NO. It is in the class of amine oxides. Although the anhydrous compound is known, trimethylamine "N"-oxide is usually encountered as the dihydrate. It is a product of the oxidation of trimethylamine, a common metabolite in animals. Both the anhydrous and hydrated materials are white, water-soluble solids. Trimethylamine "N"-oxide is an osmolyte found in saltwater fishes, sharks, rays, molluscs, and crustaceans. It is considered as a protein stabilizer that may serve to counteract urea, the major osmolyte of sharks, skates and rays. It is also higher in deep-sea
Oxide dispersion-strengthened alloy ODS steel. This process seems simple but many parameters need to be carefully controlled to produce a well made alloy. Work by Leseigneur and coworkers has been done to carefully control some of these parameters in order to get more consistent and better microstructures in ODS steels. In this two step method the oxide is ball-milled for longer periods of time to ensure a homogeneous solid solution of the oxide in the metal matrix. Then the powder is annealed at higher temperatures to begin a controlled nucleation of the nano-oxide clusters. Finally the powder is again compressed and sintered to
