Published in 2023 at "ChemPlusChem"

DOI: 10.1002/cplu.202200426

Abstract: Originating from the concept of classical chemical gardens, a new field coined 'chemobrionics' has recently emerged. In the present work, two chemobrionic systems grown from a hydrogel/liquid interface at different time scales (for 1, 7,… read more here.

Published in 2021 at "Journal of colloid and interface science"

DOI: 10.1016/j.jcis.2021.03.183

Abstract: The formation of surface multilayer structures, induced by the addition of multivalent counterions in dilute surfactant solutions, has been widely observed in a range of anionic surfactants. The phenomenon is associated with the ability to… read more here.

Published in 2017 at "Microporous and Mesoporous Materials"

DOI: 10.1016/j.micromeso.2017.07.002

Abstract: Abstract The solution structure of a gemini surfactant, C22-6-6, associated with various counterions was investigated with small-angle neutron scattering (SANS). Subsequently, C22-6-6 with various counterions (Br−, HC2O4−, C2O42−, CO32−, H2PO4−, HPO42− and OH−) was applied… read more here.

Published in 2017 at "Journal of Molecular Liquids"

DOI: 10.1016/j.molliq.2017.05.138

Abstract: Abstract Micellization of several cationic surfactants in aqueous solution and their adsorption characteristics on polytetrafluoroethylene (PTFE) surface were studied using scattering and wettability methods. The obtained results indicate that the micelle size/shape and wettability depended… read more here.

Published in 2023 at "Biomacromolecules"

DOI: 10.1021/acs.biomac.3c00066

Abstract: The material properties of cellulose nanofibers (CNFs) are governed by the surface chemical structure of the fibers. The chemical structure-property relationships for monovalent carboxylated CNFs are well understood. Here, we report the basic sheet properties… read more here.

Published in 2022 at "Langmuir"

DOI: 10.1021/acs.langmuir.1c00527

Abstract: In our latest communication, we proved experimentally that the ionic surfactant’s surface excess is exclusively determined by the size of the hydrated counterion.[Lunkenheimer, Langmuir,2017, 33, 10216−1022410.1021/acs.langmuir.7b00786]28925711. However, at this stage of research, we were unable… read more here.
