Geringfügige Beschäftigungsverhältnisse, sogenannte Minijobs, sind inzwischen ein nicht unerheblicher Teil abhängiger Beschäftigung in Deutschland. Das RWI hat im Jahr 2012...

Geringfügige Beschäftigungsverhältnisse, sogenannte Minijobs, sind inzwischen ein nicht unerheblicher Teil abhängiger Beschäftigung in Deutschland. Das RWI hat im Jahr 2012...

Marginal employment, so-called minijobs, have become an important part of dependent employment in Germany. In 2016, the RWI conducted a survey of both employees in marginal...

Lipopeptide surfactants are highly effective at reducing interfacial tension. However, there is a general lack of understanding of the relationship between their molecular...

This proposal is aimed at understanding the surface activity of the antibacterial agent, Triclosan, in the presence of surfactants. We request NR beam time on SURF to...

A number of studies have determined that non-ionic surfactants are capable of altering diffusionrates and transportation of both water and active ingredients thorough the waxy...

This work aims to exploit the unique capability of neutron reflection to examine how 2 antimicrobial lipopeptides that tend to adopt different secondary structures bind to model...

Tolaasin is a lipodepsipeptide (lipo = hydrophobic side chain, depsipeptide is an amino acid ring closed in a particular way) produced by strains of Pseudomonas tolaasii, and it...

Acyl L-Carnitines are a group of novel surfactants with attractive physical and biological properties associated with their head group charge features. This work proposes to use...

This proposal constitutes part of our ongoing study towards understanding the adsorption of collagen based polypeptide and its interaction with ionic surfactants at the...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is now emerging as an important structural signature associated with a wide range...

This proposal is to explore adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfactant anions (see Figure 1) at the air-water interface, as a function of...

The aim of the present study is to the determine, using specular neutron reflection (SNR), the structure of layers formed by novel tri-chain cationic lipids in combination with...

We propose to use neutron reflection to study the interfacial adsorption of 2 novel bispecific therapeutic antibodies at the silicon oxide/water interface. To enpower each of...

We request NR beam time on SURF to study the impact of multivalent counterions on the surface adsorption of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

The interfacial behaviour of thermoresponsive N-propylacrylamide (NPAM) based nanogels differs from solid nanoparticles because of the soft structural character. These nanogels...

Surfactants responsive to pH, temperature, CO2, and light are known, however, our recent work has shown, for the first time surfactants that are magneto-responsive, and also...

Cell adhesion and proliferation at the surface of liquids such as oil droplets is a surprising phenomenon as it is typically accepted in the field of bioengineering that cells...

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

Although surfactant detergency is well understood above 30 C, actions of surfactants below 30 C are not well established. In the era of energy saving and environment caring, we...
