Foam stability is one of the key factors determining the success of any foam-field application, and for that, it is imperative to identify surfactant formulations able to reduce the extensive foam drainage and coarsening occurring in harsh environmen

Publikováno v: Journal of molecular modeling. 24(7)

The thermodynamic stability of assemblies formed by a bis-urea-based supramolecular polymer, 2,4-bis(2-ethylhexylureido)toluene (EHUT), was investigated in solutions using either benzene or toluene as the solvent. Starting from a higher temperature i

International audience; A very limited change in the nature of the solvent (toluene versus pentylbenzene) can have an unexpectedly strong effect on the viscosity of a hydrogen bonded supramolecular polymer. In pentylbenzene, slightly stronger hydroge
