Application

Tetramethylammonium hydroxide solution can be used as:
  • A reagent in the organocatalyzed photoinduced Birch reduction of arenes to 1,4-cyclohexadienes.
  • A catalyst to synthesize 1,2-dihydro-1-arylnaphtho-oxazine-3-one derivatives via one-pot three-component condensation reaction of 2-naphthol, aromatic aldehydes, and urea.
  • A peptizing agent for magnetite nanoparticles to promote repulsive stabilization forces.
  • A template in the hydrothermal synthesis of hierarchical zeolite T aggregates with different sizes.

Potassium homeostasis is crucial for living cells. In the yeast Saccharomyces cerevisiae, the uptake of potassium is driven by the electrochemical gradient generated by the Pma1 H(+)-ATPase, and this process represents a major consumer of the gradient. We considered that

The aim of this study was to explore the synergies of laccase, a ligninolytic enzyme, with cellulose and hemicellulase amendments on ensiled corn stover. Molecular signals of lignin decomposition were observed by tetramethylammonium hydroxide thermochemolysis and gas chromatography-mass spectroscopy (TMAH-GC-MS)
