General description
Sodium hydroxide is an inorganic base. It participates in the oxidation of glycerol, catalyzed by Au/charcoal or Au/graphite. It also participates in solvent-free aldol condensation reaction.
Application
Sodium hydroxide may be employed for determination of specific surface area of colloidal silica, via titration. It may be employed for direct oxidation of sodium borohydride, which was investigated by cyclic and linear voltammetry, chronoamperometry and chronopotentiometry. It may be used to compose citrate buffer and borate buffers.
It may be used in the synthesis of following compounds:
It may be used in the synthesis of following compounds:
- alkylaryl amidosulfobetaines
- (3 -[4-teroctylphenoxyethoxyethoxyethyl] dimethylammonio propane sulfonate (XOSB)
- trisulfobetaines (TriSBn)

This report describes a UV laser photoablation method for the production of miniaturized liquid-handling systems on polymer substrate chips. The fabrication of fluid channel and reservoir networks is accomplished by firing 200 mJ pulses from an UV excimer laser at

Severe quantitative loss of protein is often observed in high-resolution two-dimensional electrophoresis of membrane proteins, while the resolution is usually not affected. To improve the solubility of proteins in this technique, we tested denaturing cocktails containing various detergents and chaotropes.
