Wetting of nanopores probed with pressure

Aleksandra Radenovic, Andrey Chernev, Sanjin Marion, Michal Daniel Macha, Sebastian James Davis

Nanopores are both a tool to study single-molecule biophysics and nanoscale ion transport, but also a promising material for desalination or osmotic power generation. Understanding the physics underlying ion transport through nano-sized pores allows better ...

From vesicles to materials: bioinspired strategies for fabricating hierarchically structured soft matter

Esther Amstad

Certain organisms including species of mollusks, polychaetes, onychophorans and arthropods produce exceptional polymeric materials outside their bodies under ambient conditions using concentrated fluid protein precursors. While much is understood about the ...

Phase behaviour and structure of a model biomolecular condensate

Julian Charles Shillcock

Phase separation of immiscible fluids is a common phenomenon in polymer chemistry, and is recognized as an important mechanism by which cells compartmentalize their biochemical reactions. Biomolecular condensates are condensed fluid droplets in cells that ...

Swelling-Induced Chain Stretching Enhances Hydrolytic Degrafting of Hydrophobic Polymer Brushes in Organic Media

Harm-Anton Klok, Jian Wang

Hydrophilic polymer brushes grown via surface‐initiated polymerization from silicon oxide surfaces can detach or degraft in aqueous media. Degrafting of these chain end‐tethered polymers is believed to involve hydrolysis of bonds at the polymer–substrate i ...

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 ...

Synthesis of Loop Poly(Methyl Methacrylate) Brushes via Chain-End Postpolymerization Modification

Harm-Anton Klok, Piotr Mocny

Polymer brushes are typically densely grafted assemblies of polymer chains that are tethered via one end group to a solid substrate. Anchoring linear polymer chains via both end groups to a surface results in loop-type polymer brushes. Although loop polyme ...

Adhesion and interfacial healing between supramolecular hybrid networks and glass substrates

Véronique Michaud, Federica Sordo

Adhesion towards glass and interfacial healing of partially supramolecular hybrid polymer networks featuring a range of H-bdnds content were investigated through two dedicated adhesion test methods. In a first series of tests, adhesion strength was measure ...
