Autor: Sylvain, Prévost, Sebastian, Krickl, Stjepan, Marčelja, Werner, Kunz, Thomas, Zemb, Isabelle, Grillo

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 37(13)

Even in the absence of surfactants, polymers, or particles, spontaneous emulsions produced by dilution with water can be stable over days. This "Ouzo effect" used by the industry is obtained by rapid dilution from an identified "pre-Ouzo" domain of c

Autor: Sebastian Krickl, Andreas Nazet, Magdalena Luger, Sergej Friesen, Richard Buchner, Glenn Hefter

Publikováno v: Physical Chemistry Chemical Physics. 20:8812-8821

Aqueous solutions of five lanthanide salts: LaCl3, La(NO3)3, La2(SO4)3, Eu(NO3)3 and Eu2(SO4)3 have been studied at 25 °C by dielectric relaxation spectroscopy over the frequency range 0.05 ≤ ν/GHz ≤ 89. Detailed analysis of the solvent-related

Investigation of ethanolamine stabilized natural rubber latex from Taraxacum kok-saghyz and from Hevea brasiliensis using zeta-potential and dynamic light scattering measurements

Autor: Sebastian Krickl, Didier Touraud, Werner Kunz

Publikováno v: Industrial Crops and Products. 103:169-174

For pH adjustment and long-term preservation of natural rubber (NR 1 ) latex, the usage of ammonia or KOH is still state of the art. Unfortunately, ammonia has a bad odor, it is volatile and toxic and thus does not provide safe and comfortable handli

Ab initio prediction of structuring/mesoscale inhomogeneities in surfactant-free microemulsions and hydrogen-bonding-free microemulsions

Autor: Arno Pfitzner, Gašper Jošt, Maximilian Hahn, Werner Kunz, Didier Touraud, Thomas Buchecker, Pierre Bauduin, Sebastian Krickl, Andreas Klamt

Publikováno v: Physical chemistry chemical physics : PCCP. 21(15)

In this paper, we consider the influence of H-bond donor and acceptor functionalities on the formation of mesoscale inhomogeneities in ternary systems. It was found that hydrogen-bonding re-enforces such structures, but is not necessarily a prerequis

International audience; In the present contribution, the pre-structuring of binary mixtures of hydrotropes and H2O is linked to the solubilisation of poorly water miscible compounds. We have chosen a series of short-chain alcohols as hydrotropes and

Surfactant-free microemulsion electrokinetic chromatography (SF-MEEKC) with UV and MS detection - a novel approach for the separation and ESI-MS detection of neutral compounds

Publikováno v: Analytical and Bioanalytical Chemistry. 408:8681-8689

Microemulsion electrokinetic chromatography (MEEKC) is a powerful tool to separate neutral species based on differences in their hydrophobic and hydrophilic properties. However, as a major drawback the conventionally used SDS based microemulsions are

In the present contribution, we investigated the influence of the structuring of surfactant-free microemulsions (SFME) (water/1-propanol/limonene and water/tert-butanol/limonene) on the enzyme activity of horseradish peroxidase (HRP). To this purpose

Surfactant-free microemulsions (SFME) comprising a cleavable hydrotrope/hydrophobic component were investigated regarding potential applications for green, microemulsion-mediated extraction processes. To this purpose, dynamic light scattering (DLS) e
