Design and Synthesis of Bio-based Amphiphiles from Lignocellulosic Biomass

In the pursuit of a carbon-neutral chemical industry, minimizing fossil feedstock consumption while integrating renewable carbon sources is imperative. Surfactants, inherently amphiphilic, pose challenges in separation and recovery processes. Given their e ...

Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics

Philip Robin Loche

Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...

The interfacial structure of nano-and micron-sized oil and water droplets stabilized with SDS and Span80

Sylvie Roke, Esther Amstad, Nikolay Smolentsev, Evangelia Zdrali, Gianluca Nicolas Etienne

In this work, we provide a comparison between the stability and the interfacial structure of micrometer-sized and nanometer-sized droplets by employing a multi-instrumental approach comprised of the surface-sensitive technique of sum frequency scattering a ...

Formation of N-nitrosamines by micelle-catalysed nitrosation of aliphatic secondary amines

Urs von Gunten, Florian Frédéric Vincent Breider, Isuf Salihu

N-Nitrosamines are an important class of potent human carcinogens and mutagens that can be present in water and wastewater. For instance, N-nitrosamines can be formed by reaction of nitrosating agents such as NO+ or N2O3 formed from nitrite under acidic co ...

Hydration mediated interfacial transitions on mixed hydrophobic/hydrophilic nanodroplet interfaces

Sylvie Roke, Nikolay Smolentsev, Halil Ibrahim Okur, Rüdiger Scheu, Filip Kovacik

Interfacial phase transitions are of fundamental importance for climate, industry, and biological processes. In this work, we observe a hydration mediated surface transition in supercooled oil nanodroplets in aqueous solutions using second harmonic and sum ...

Kleptoplastidic benthic foraminifera from aphotic habitats: Assimilation (or not) of inorganic C, N, and S studied at sub-cellular resolution

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

The assimilation of inorganic compounds and their role in the foraminiferal metabolism compared to predation or organic matter assimilation is unknown. Here we investigate these processes with a study of the species Nonionellina labradorica (Dawson, 1860), ...

Molecular Structure Inhibiting Synergism in Charged Surfactant Mixtures: An Atomistic Molecular Dynamics Simulation Study

Satoshi Takahama, Mária Lbadaoui-Darvas

Synergistic and nonsynergistic surfactant-water mixtures of sodium dodecyl sulfate (SDS), lauryl betaine (C12B), and cocoamidopropyl betaine (CAPB) systems are studied using molecular simulation to understand the role of interactions among headgroups, tail ...

Biocompatible Amphiphilic Hydrogel–Solid Dimer Particles as Colloidal Surfactants

Esther Amstad, Jing Fan

Emulsions of two immiscible liquids can slowly coalesce over time when stabilized by surfactant molecules. Pickering emulsions stabilized by colloidal particles can be much more stable. Here, we fabricate biocompatible amphiphilic dimer particles using a h ...

Novel Chemosensors for Biologically Important Analytes

Ziya Köstereli

In this work, fluorescent-based chemosensors for the detection of important analytes in aqueous solution are described. The sensors are based on different detection concepts, including analyte-induced aggregation/de-aggregation, pattern-based sensing and m ...

Soft nanofluidics governing minority ion exclusion in charged hydrogels

Fabien Patrick Wildhaber, Songmei Wu, Thomas Michael Braschler, Sidi Ahmed Bencherif

We investigate ionic partition of negatively charged molecular probes into also negatively charged, covalently crosslinked alginate hydrogels. The aim is to delimit the domain of validity of the major nanoelectrostatic models, and in particular to assess t ...
