[2] [3] [4] The term dialysis was first routinely used for scientific or medical purposes in the late 1800s and early 1900s, pioneered by the work of Thomas Graham. The first mass-produced man-made membranes suitable for dialysis were not available until the 1930s, based on materials used in the food packaging industry such as cellophane.
The salt is a white solid that is soluble in polar organic solvents. Vilsmeier reagent is the active intermediate in the formylation reactions, the Vilsmeier reaction or Vilsmeier-Haack reaction that use mixtures of dimethylformamide and phosphorus oxychloride to generate the Vilsmeier reagent, which in turn attacks a nucleophilic substrate and ...
Viskase (formerly Visking) is a global corporation based out of Lombard, Illinois, United States that supplies plastic, cellulose, and fibrous film and packaging to the food service industry, including casings for processed meats such as hot dogs and sausages.
Dialysis is the process used to change the matrix of molecules in a sample by differentiating molecules by the classification of size. [6] [7] It relies on diffusion, which is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached.

Trimethylsilylpropanoic acid (TMSP or TSP) is a chemical compound containing a trimethylsilyl group. It is used as internal reference in nuclear magnetic resonance for aqueous solvents (e.g. D 2 O). For that use it is often deuterated (3-(trimethylsilyl)-2,2,3,3-tetradeuteropropionic acid or TMSP- d 4 ). [ 1 ]

Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea. [1] It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. [1] Oral rehydration therapy can also be given by a nasogastric tube. [1]
