Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent [1] and also as a low-residue bactericide in such processes as hydrofracking. [2] In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively ...
Hanks' salts is a collective group of salts rich in bicarbonate ions, formulated in 1940 by the microbiologist John H. Hanks. [1] Typically, they are used as a buffer system in cell culture media and aid in maintaining the optimum physiological pH (roughly 7.0–7.4) for cellular growth.
In the early pharmacological literature, however, there are references to the use of "tetramethylammonium hydroxide" or "tetramethylammonium hydrate", which were meant to facilitate comparison between weight-based dosages of different TMA salts, [18] but did not involve the actual use of tetramethylammonium hydroxide, whose strong basicity ...
According to Bapton, sugar and salt technically never expire. But some of the ingredients added to salt, like iodine, can start to break down, so try to use it within 5 years.
Dough conditioners may include enzymes, yeast nutrients, mineral salts, oxidants and reductants, bleaching agents and emulsifiers. [1] They are food additives combined with flour to improve baking functionality. Flour treatment agents are used to increase the speed of dough rising and to improve the strength and workability of the dough.
It's a shame that so many well-intentioned but misguided recipes encourage us to use milk curdled with lemon juice or vinegar as a replacement for buttermilk. That's bad advice, especially with ...
In the US, about 750 compounds have been listed as additives for hydraulic fracturing, also known as ingredients of pressurized fracking fluid, [9] in an industry report to the US Congress in 2011 [10] [11] The following is a partial list of the chemical constituents in additives that are used or may have been used in fracturing operations.
