The structural and viscoelastic properties of monolayers at the air/water interface are of substantial interest from a scientific point of view, as well as of paramount importance for technological applications from soap films to surface coatings.
We currently investigate the class of semifluorinated alkanes at the air/water interface in order to develop a detailed structure-properties...

Colloidal suspensions of microgel particles are systems of great interest for applications and fundamental studies due to their reversible responsiveness to changes of their environment, such as temperature or hydrostatic pressure. Although it has been shown that microgel particles behave like hard spheres under many circumstances [1], they can reach states that are far beyond hard spheres due...

We investigated snapshots of the fibrillation and aggregation kinetics of multi-stranded β-lactoglobulin amyloid protein fibrils at pH 2 and 90 °C by combining scattering (SANS, DLS, DDLS) as well as atomic force microscopy (AFM) 1. Scattering techniques clearly demonstrate the structural conversion and time evolution of β-lactoglobulin monomers (2 wt %) into semi-flexible protein fibrils upon...

Dronpa may be regarded as the prototype of photochromic proteins. These fluorescent proteins can be reversibly switched between a fluorescent bright and a non-fluorescent dark state by light excitation of the chromophore. Although the X-ray structure of Dronpa in both states has been determined in great detail little is known about the actual switching process itself.
We performed...
