TLDR
Aqueous formamide (20%) was found to exert a specific effect on the germicidal power of formic and acetic acids and also of ammonium hydroxide: bactericidal action against Bacr. aerogenes was increased six to twelvefold as mentioned in this paper.Abstract:
Aqueous formamide (20%) was found to exert a specific effect on the germicidal power of formic and acetic acids and also of ammonium hydroxide: bactericidal action against Bacr. aerogenes was increased six- to twelve-fold. Certain other disinfecting substances were affected by formamide to a much less extent, e.g. phenols, isopropyl alcohol, acetone, oxalic acid, lactic acid, and various esters, while o-chlorophenol and trichloracetic acid were actually diminished in germicidal activity. Possible explanations for the observed results are discussed.read more

D.m.a. and d.s.c. investigations of the β transition of poly(vinylidene fluoride)
TL;DR: The origin of the β transition in polyvinylidene fluoride (PVDF) is still a pending question as discussed by the authors, and the transition has been studied by dynamic mechanical analysis (dma) and differential scanning calorimetry (dsc) in dependence on sample annealing and dilution with ϵ-caprolactam (CPL).

A new polymeric HALS: preparation of an addition polymer of DGEBA–HALS and its photostabilizing effect
TL;DR: In this paper, a linear epoxide-amine type of a new polymeric HALS was prepared by an addition polymerization of 2,2-bis(4-glycidyloxyphenyl)propane and 4-amino-2,2,6,6-tetramethylpiperidine (ATMP) in chlorobenzene.

The influence of organic solvents on the bactericidal action of the phenols. Part II
TL;DR: In this paper, the influence of organic solvents on the bactericidal power of the phenols, alcohols, and other germicides was investigated, and it was shown that aliphatic compounds, e.g., tert.-buryl alcohol and ethylene glycol monobutyl ether, were more effective against B. lactis aerogetics in 10% concentration and against Staphylococcus in 3% solution.

The influence of ethylene glycol and glycerol on the germicidal power of aliphatic and aromatic compounds
TL;DR: In this article it was shown that glycol and glycerol, whilst causing a diminution in the bactericidal action of phenols, actually enhance the germicidal power of certain aliphatic compounds.
