Our group works on the relation between sound-exposure and auditory performance. During the last decade we thoroughly tested the sense of hearing of about ten thousand persons, and we tried to determine their exposure to sound by a detailed questionn

A summary of more than two decades of research, related to the relationship between the acoustic environment and the auditory threshold. Special groups have been examined: professional musicians, dentists, fans and avoiders of discotheques, office pe

The relaxation of composition fluctuations of diblock copolymers in the intermediate wavevector range 0.08 < q/q* < 0.61 is investigated by photon correlation spectroscopy, thus bridging the q/q* ≪...

We report about self-diffusion experiments on a compositionally asymmetric poly(ethylene-co-propylene)-block-poly(dimethylsiloxane) diblock copolymer exhibiting the lamellar and the gyroid morphology. The echo attenuation curves were analyzed by fitt

The dynamics of hairy-rod poly(p-phenylene)s in isotropic solutions are investigated by pulse field gradient NMR (PFG−NMR) and dynamic shear rheology for four different contour lengths over a broad concentration range. The self-diffusion coefficien

Upon heating, concentrated solutions of star polymers and block copolymer micelles in a good solvent, representing soft spheres, undergo a reversible gelation. This phenomenon is attributed to the formation of clusters causing a partial dynamic arres

The concentration dependence of the self-diffusivity of a hydrogenated polystyrene-block-polybutadiene-block-polystyrene triblock copolymer in an n-heptane solution (c = 0.58−6.9 g/100 mL) was investigated using the pulsed field gradient NMR at 20

The mean-square displacement, Δr2, of very high molecular weight diblock copolymers in solutions near the disorder-to-order transition is investigated by pulsed-field-gradient NMR. The thermodynamic potential influencing the motion leads to a time-i
