DOI: 10.1016/j.biortech.2017.07.058

Abstract: Some zwitterionic surfactants exhibit upper critical solution temperature (UCST) in aqueous solutions. For the zwitterionic surfactant solution mixed with cellulase, when its temperature is below UCST, the cellulase can be recovered by coprecipitation with zwitterionic… read more here.

DOI: 10.1021/acsomega.2c04642

Abstract: The wide application of surfactants has a harmful effect on the environment, drawing more attention to the development and application of low-toxicity surfactants. A salt-tolerant and low-toxicity biobased zwitterionic surfactant, N,N-dimethyl-N-[2-hydroxy-3-sulfo-propyl]-N-benzyloxyoctadecanoyl-1,3-propanediamine (SPBOPA), was prepared from… read more here.

DOI: 10.1021/acsomega.5c08858

Abstract: Although formally neutral, in aqueous media, zwitterionic micelles selectively concentrate the anions of added inorganic salts at the micelle-water interface. The resultant negative electrostatic potential of the micelles can be additionally modulated by the metal… read more here.
