Lithium acetate is used in the laboratory as buffer for gel electrophoresis of DNA and RNA. It has a lower electrical conductivity and can be run at higher speeds than can gels made from TAE buffer (5-30V/cm as compared to 5-10V/cm). At a given voltage, the heat generation and thus the gel temperature is much lower than with TAE buffers ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
2 O, in the form of rod-like crystals about 8 μm long and 0.4 μm wide, with lithium hydroxide LiOH, up to 750–900 °C. [9] A third method uses lithium acetate, cobalt acetate, and citric acid in equal molar amounts, in water solution. Heating at 80 °C turns the mixture into a viscous transparent gel.
A solution of lithium chloride in DMAc (LiCl/DMAc) can dissolve cellulose. Unlike many other cellulose solvents, LiCl/DMAc gives a molecular dispersion, i.e. a "true solution". For this reason, it is used in gel permeation chromatography to determine the molar mass distribution of cellulose samples.
The Food and Drug Administration's new rules on "healthy" food labels are voluntary and are scheduled to take effect at the end of February.
Novo Nordisk’s latest attempt in weight loss, a combination drug called CagriSema, matched the bar set by Lilly’s currently approved medicine, Zepbound, but didn’t cleanly surpass it in late ...
The consumer price index released on October 10 showed inflation cooling to its lowest level since February 2021, with a 2.4% year-over-year increase in consumer prices in September, down from 2.5 ...
It can be prepared by metathesis reaction between sodium azide and lithium nitrate or lithium sulfate solutions: NaN 3 + LiNO 3 → LiN 3 + NaNO 3 2 NaN 3 + Li 2 SO 4 → 2 LiN 3 + Na 2 SO 4 [3] It can also be prepared by reacting lithium sulfate with barium azide. Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4 [2]
