While the review stated that it is unclear which artificial tear formulation works best, two trials found that 0.2% polyacrylic acid-based tears were more effective in treating dry eye symptoms over 1.4% polyvinyl alcohol-based tears.
A wide range of grafting combinations were attempted including work with acrylic acid, acrylamide and polyvinyl alcohol (PVA). Today's research has proved the ability of natural materials, e.g. polysaccharides and proteins, to perform super absorbent properties in pure water and saline solution (0.9%wt.) within the same range as synthetic ...
EC 1.1.99.23: Now EC 1.1.2.6, polyvinyl alcohol dehydrogenase (cytochrome) ... EC 1.4.3.18: Not approved as the enzyme was shown to be a dehydrogenase and not an ...
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde .
Flubber, also commonly known as slime, is a non-Newtonian fluid, easily made from polyvinyl alcohol–based glues (such as white "school" glue) and borax. It flows under low stresses but breaks under higher stresses and pressures. This combination of fluid-like and solid-like properties makes it a Maxwell fluid.
In enzymology, a polyvinyl-alcohol oxidase (EC 1.1.3.30) is an enzyme that catalyzes the chemical reaction. polyvinyl alcohol + O 2 oxidized polyvinyl alcohol + H 2 O 2. Thus, the two substrates of this enzyme are polyvinyl alcohol and O 2, whereas its two products are oxidized polyvinyl alcohol and H 2 O 2.
In enzymology, a polyvinyl-alcohol dehydrogenase (acceptor) (EC 1.1.99.23) is an enzyme that catalyzes the chemical reaction polyvinyl alcohol + acceptor ⇌ {\displaystyle \rightleftharpoons } oxidized polyvinyl alcohol + reduced acceptor
Animal glue was the most common woodworking glue for thousands of years until the advent of synthetic glues, such as polyvinyl acetate (PVA) and other resin glues, in the 20th century. Today it is used primarily in specialty applications, such as lutherie , pipe organ building , piano repairs, and antique restoration.
