General description

Combined effect of NaNO2 and NaCl on the growth of Listeria monocytogenes in tryptone soya broth has been investigated using automated turbidimetric system. Its carcinogenic effects in F-344 rats have been evaluated.

Application

Sodium nitrite may be used as a standard for the quantitative determination of nitrite in culture medium. It may be used in the preparation of isopropyl nitrite, via reaction with isoamyl alcohol.

We investigated the self-assembled structures and photoresponsive and crystallization behaviors of supramolecules composed of 4-methoxy-4'-hydroxyazobenzene (Azo) molecules and polyethylene glycol (PEG) that were formed through hydrogen-bonding interactions. The Azo/PEG complexes exhibited the characteristics of photoresponse and crystallization, which originated from
