Using essentially the same procedure above but changing citrate to poly ( vinyl pyrrolidone ) ( PVP ) yields cube and rod-shaped nanostructures instead of triangular nanoprisms.
12.
The major metabolites of Oxiracetam include : beta-hydroxy-2-pyrrolidone, N-aminoacetyl-GABOB, GABOB ( beta-hydroxy-GABA ) and glycine.
13.
Some of them, e . g . tapioca flour, lactose, sucrose, microcrystalline cellulose, poly vinyl pyrrolidone and various starches are also used in pharmacology in making tablets.
14.
Alternative routes include the partial hydrogenation of succinimide and the carbonylation of allylamine with methyl amine . 2-Pyrrolidone is an intermediate in the production of vinylpyrrolidone and the drug piracetam.
15.
A later team at Zambon modified the pyrrolidine with a pyrrolidone could produce an analogue some 318x morphine in its analgesic activity in animal studies ( the latter overlays beta hydroxy fentanyl ).
16.
Metabolic studies show that the pyridine ring of nicotine is derived from niacin ( nicotinic acid ) while the pyrrolidone is derived from " N "-methyl-? 1-pyrrollidium cation.
17.
CHP is used in the electronics industry as a photoresist stripper ( usually in combination with other solvents like N-methyl-2-pyrrolidone ), and as a chemical polisher of copper in circuit board fabrication.
18.
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH . In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers ( such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide and some cellulose ethers ) and form hydrogen-bonded interpolymer complexes.
19.
Many different solvents are suitable, including sulfolane ( C 4 H 8 O 2 S ), furfural ( C 5 H 4 O 2 ), tetraethylene glycol ( C 8 H 18 O 5 ), dimethylsulfoxide ( C 2 H 6 OS ), and N-methyl-2-pyrrolidone ( C 5 H 9 NO ).
20.
PVDF is the standard binder material used in the production of composite electrodes for lithium-ion batteries . weight solution of PVDF dissolved in " N "-methyl-2-pyrrolidone ( NMP ) is mixed with an active lithium storage material such as graphite, silicon, tin, LiCoO 2, LiMn 2 O 4, or LiFePO 4 and a conductive additive such as carbon black or carbon nanofibers.
