Published in 2022 at "Ecology"

DOI: 10.1002/ecy.3868

Abstract: Many riverine systems experience periodic flooding events as part of their natural flow regimes. These events can provide nutrients, create access to seasonal environments, and refill associated wetlands (Junk et al., 1989; Pringle, 2001). Understanding… read more here.

Published in 2017 at "Journal of Surfactants and Detergents"

DOI: 10.1007/s11743-017-2009-x

Abstract: Three glucosamide-based polysiloxanes (GAPS) surfactants were prepared by amidation of gluconolactone with amino functional polysiloxanes synthesized by polymerization. GAPS were characterized by FT-IR, 1H NMR and 13C NMR. Surface activity and aggregation behavior in aqueous… read more here.

Published in 2018 at "Carbohydrate polymers"

DOI: 10.1016/j.carbpol.2017.11.089

Abstract: Chitosan polyelectrolyte complex with high surface activity has been prepared by salt complexation of chitosan with hexadecyl-oligo-oxyethylene hemisuccinate (HOS), an anionic surfactant. Physicochemical properties of chitosan-HOS complex can be explained by unusual structure of HOS… read more here.

Published in 2021 at "Journal of biotechnology"

DOI: 10.1016/j.jbiotec.2021.05.002

Abstract: Their surface activity enables proteins to form and stabilize foam, which can be used for in situ product separation or foam fractionation. Thus, it would be highly desirable to predict the surface activity of proteins… read more here.
