The multiple scattering problem of small angle neutron scattering (SANS) is revisited using differential equations from which different contributions are derived. The coherent scattering is connected to multiple scattering events and the ideal single scattering cross sections can be related to the apparent scattering cross section. [...]

For many applications, mesoporous titania nanostructures are exposed to water or need to be backfilled via infiltration with an aqueous solution, which can cause deformations of the nanostructure by capillary forces. In this work, the degree of deformation caused by water infiltration in two types of mesoporous, nanostructured titania films exposed to water vapor is com-pared. [...]

Neutron protein crystallography is a technique which can readily report on the hydrogen atom positions in proteins. This is in some cases valuable information on drug target proteins and their hydrogen bonding with substrates and inhibitors. [...]

With the advent of new instruments (e. g. [...]

The neutron single crystal diffractometer BIODIFF at the research reactor Heinz Maier-Leibnitz (FRM II) is especially designed to collect data from crystals with large unit cells. The main field of application is the structural analysis of proteins, especially the determination of hydrogen atom positions. [...]

Molecular dynamics in proteins animate and play a vital role for biologically relevant processes of these biomacromolecules. Quasielastic incoherent neutron scattering (QENS) is a well-suited experimental method to study protein dynamics from the picosecond to several nanoseconds and in the Ångström length-scale. [...]
