Fluoro- vs hydrocarbon surfactants: why do they differ in wetting performance? [PDF]
, 2014 Fluorosurfactants are the most effective compounds to lower the surface tension of aqueous solutions, but their wetting properties as related to low energy hydrocarbon solids are inferior to hydrocarbon trisiloxane surfactants, although the latter ...

Emulsification of Hydrocarbon Fermentation Broth by Surfactants [PDF]
Agricultural and Biological Chemistry, 1967 In order to perform hydrocarbon fermentation satisfactorily, it was necessary to get the sample representing the real feature of the broth. However, Corynebacterium hydrocarboclastus S10B1, which could accumulate a good deal of l-glutamic acid, formed a coagulated mass of cells like pellet as they grew up, making the broth heterogeneous, To obtain ...
