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

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 ...

Sulfated and sulfonated dendritic polyglycerols and use thereof as broad-spectrum virucidal agents

Francesco Stellacci, Matteo Gasbarri

The invention relates to dendritic polyglycerol (dPG) compounds with alkyl-sulfonate/ sulfate functional groups that irreversibly inhibit viral infection (virucidal effect) through multivalent interaction in nanomolar concentration range. While the compoun ...

Computer Simulation of the Surface of Aqueous Ionic and Surfactant Solutions

Mária Lbadaoui-Darvas

The surface of aqueous solutions of simple salts was not the main focus of scientific attention for a long while. Considerable interest in studying such systems has only emerged in the past two decades, following the pioneering finding that large halide io ...

In-vitro digestion of Tire and Road Wear Particles: Bioavailability of metals and Polycyclic Aromatic Hydrocarbons

Kristin Schirmer, Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Thibault Béranger Masset

The potential impact of Tire and Road Wear Particles (TRWP) on aquatic organisms has recently gained attention since the occurrence of TRWP in the aquatic environment has been observed in surface water and sediments of numerous regions. Moreover, the inges ...

Shear Stress-Responsive Polymersome Nanoreactors Inspired by the Marine Bioluminescence of Dinoflagellates

Esther Amstad, Antoine Claude Jean Vian

Some marine plankton called dinoflagellates emit light in response to the movement of surrounding water, resulting in a phenomenon called milky seas or sea sparkle. The underlying concept, a shear-stress induced permeabilisation of biocatalytic reaction co ...

Carbon Nanomaterials from Oligoyne Surfactants

Enzo Jean Raymond Bomal

Carbonaceous nanocoatings such as diamond-like amorphous carbon or graphene layers exhibit remarkable properties in multiple fields, ranging from corrosion protection to electronics and lubrication. However, they are typically deposited from the vapor phas ...

Self-Assembly of Microscopic Rods Due to Depletion Interaction

Ignacio Pagonabarraga Mora

In this article, using numerical simulations we investigate the self-assembly of rod-like particles in suspension due to depletion forces which naturally emerge due to the presence of smaller spherical depletant particles. We characterize the type of clust ...

Fluorinated surfactants in droplet-based microfluidics: Influence of their composition on the properties of emulsion drops

Gianluca Nicolas Etienne

Miniaturization has been a driving force in many areas of science and technology, most notably in the electronics industry. Droplet-based microfluidics, a methode to produce emulsion drops in a controlled way and at high-throughputs, enables the miniaturiz ...

Molecular Level Interfacial Studies of Nanoemulsions: Surface Structure, Specific Ion Effects and Stability

Evangelia Zdrali

This thesis is a study on the molecular structure of the interface of nanometer-sized oil droplets dispersed in water, a system known as oil-in-water nanoemulsion. The motivation for this research is the large significance of the interfacial nanostructures ...

Selectively Permeable Double Emulsions

Esther Amstad, Irvine Lian Hao Ong

Natural organisms are made of different types of microcompartments, many of which are enclosed by cell membranes. For these organisms to display a proper function, the microcompartments must be selectively permeable. For example, cell membranes are typical ...
