Facile synthesis of oligoyne amphiphiles and their rotaxanes

Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Ruth Szilluweit, Martin Fritzsche, Emmanuel Romaric Contal

Carbon-rich organic compounds containing a series of conjugated triple bonds (oligoynes) are relevant synthetic targets, but an improved access to oligoynes bearing functional groups would be desirable. Here, we report the straightforward synthesis of two ...

Influence of the wetting angle on capillary forces in pressure infiltration

Andreas Mortensen, Ludger Weber, Alain Léger

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature press ...

Synthesis of magnetic cobalt ferrite nanoparticles with controlled morphology, monodispersity and composition: the influence of solvent, surfactant, reductant and synthetic conditions

In our present work, magnetic cobalt ferrite (CoFe2O4) nanoparticles have been successfully synthesised by thermal decomposition of Fe(III) and Co(II) acetylacetonate compounds in organic solvents in the presence of oleic acid (OA)/oleylamine (OLA) as surf ...

Solid-On-Liquid Technology for Suspended Microchannel Fabrication

Annalisa De Pastina, Antoine Nicolas Désiré Aupée

In this project a new fabrication strategy for suspended microchannel resonators (SMRs) is described. SMRs are biosensing devices with the liquid flowing inside of them, allowing real time measurements of fluidic samples, while devices can be kept in dry e ...

Manipulation of cellulose nanocrystal surface sulfate groups toward biomimetic nanostructures in aqueous media

Justin Orazio Zoppe

We report a facile aqueous procedure to create multivalent displays of sulfonated ligands on CNCs for future applications as viral inhibitors. CNCs were decorated with model compounds containing sulfonate groups via reactions of epoxides and isothiocyanate ...

Specific Ion Effects in Amphiphile Hydration and Interface Stabilization

Sylvie Roke, Yixing Chen, Rüdiger Scheu

Specific ion effects can influence many processes in aqueous solutions: protein folding, enzyme activity, self-assembly, and interface stabilization. Ionic amphiphiles are known to stabilize the oil/water interface, presumably by dipping their hydrophobic ...

Ultrathin Shell Double Emulsion Templated Giant Unilamellar Lipid Vesicles with Controlled Microdomain Formation

Esther Amstad

A microfluidic approach is reported for the high-throughput, continuous production of giant unilamellar vesicles (GUVs) using water-in-oil-in-water double emulsion drops as templates. Importantly, these emulsion drops have ultrathin shells; this minimizes ...

Cell Compatible Arginine Containing Cationic Polymer: One-Pot Synthesis and Preliminary Biological Assessment

Lucia Baldi Unser, Jutta Christine Wandrey, Xiao Shen, Nino Zavradashvili, Tamar Memanishvili

Synthetic cationic polymers are of interest as both nonviral vectors for intracellular gene delivery and antimicrobial agents. For both applications synthetic polymers containing guanidine groups are of special interest since such kind of organic compounds ...

Drops can bounce from perfectly hydrophilic surfaces

John Martin Kolinski

Drops are well known to rebound from superhydrophobic surfaces and from liquid surfaces. Here, we show that drops can also rebound from a superhydrophilic solid surface such as an atomically smooth mica sheet. However, the coefficient of restitution CR ass ...
