4 years after observations of almost free rotation in solid methane II (Kapulla and W. Gläser, 1970) B. Alefeld and A. Kollmar performed the first backscattering experiment. Together with that on methane tunneling it set the start to many more neutron experiments dedicated to quantum rotations. Neutron spectra with well-defined lines, both benefitted from theoretical work and stimulated it;...

Working on the glass transition phenomenon requires a thermodynamic and dynamical description of the materials, molecules, polymers or proteins. In text books, the phenomenon is described as a kinetic phase transition, arising between an out-of-equilibrium solid and a very viscous supercooled liquid as temperature decreases. Starting neutron scattering experiments by using backscattering...

We present quasielastic neutron scattering results on hydrous silica, sodium aluminosilicate, and sodium trisilicate melts with 10mol% total water content, studied at high temperature under high pressure. Combining neutron timeof-
flight spectrometry with neutron backscattering, intrinsic, microscopic proton dynamics is investigated on a timescale from 0.2 ps up to 1 ns between 850K and...

Confinement presents an unprecedented opportunity to produce and study new materials properties on the nanometer scale. Over the past decades, fundamental questions arising from systems confined in nanochannels have been addressed by impregnation of molecular fluids within nano/mesoporous structures. For pore sizes smaller than few tens of nanometers, strong interfacial and finite size effects...

A polymer is a condensed matter system where the structural units are macromolecules –big molecules built up by repetition of a more or less simple chemical motif (monomer) mainly based on carbon and hydrogen atoms. Polymers display rich and complex dynamics, including different atomic and molecular processes, which spread over very different time and length scales. On the one hand, polymers...

With the fast evolution of molecular dynamic simulations of proteins in the eighties, experimental methods covering structural fluctuations on a picosecond time scale came into focus. Time of flight methods and neutron backscattering provided numerous reality tests of virtual molecular biology. From the experimental side came the idea to expand the physiological range down to low temperatures,...

Molecular motion in soft matter, including polymers, reaches a high degree of complexity, far beyond that observed in small molecules. Chain connectivity plays a major role and, as a result, dynamic processes extend over an exceedingly wide time and length scale. Therefore, a complete, accurate picture of molecular motion in these systems can only be achieved by combining experimental...
