We investigate mass transport and flow behaviour of liquid alloys, which are key properties for material processing. Quasielastic neutron scattering provides a unique possibility to access the dynamics of the melt on microscopic time and length scales. On the one hand, this allows the precise measurement of self-diffusion coefficients at elevated temperatures without any convective effect. On...
This contribution will discuss recent QENS experiments under in-situ illumination including sample structure, specific instrument setup and desirable future instrument options. As an example, data of the orange carotenoid protein (OCP) will be presented. OCP plays a vital role in the photoprotection of cyanobacteria and exhibits a significant structural change upon photoactivation. A rarely...
Sickle cell disease (SCD) is a genetic blood disorder, inducing severe anemia. It results from the polymerization of the oxygen-carrying protein hemoglobin found in red blood cells (RBC), which leads to a deformation of the cells to rigid, sickle-like shape under certain circumstances that will obstruct capillaries vessels, and will ultimately induce the disease of different organs. The...
We present a major upgrade for TRISP. Through optimized beam geometry and development of a spin-echo multi-detector, gain factors of 5-50 are possible. The proposed multi spin-echo analyzer is both suited for continuous and TOF operation.
The current J-NSE represents at the moment the best known design of an NSE Spectrometer, enabling measurements with correlation times up to several 100 nanoseconds in routine operation. An important area of science at the J-NSE is the investigation of domain motion in large proteins under physiological conditions, a unique capability of NSE, requiring extremely high precision measurements...
In my talk I will highlight ongoing work in my group concerning structure and dynamics of the intrinsically disordered myelin basic protein (MBP) and its interaction with biomimetic myelin membranes as well as effects of macromolecular crowding on the liquid liquid phase transition of MBP. Additionally, I will present recent work on changes of molecular dynamics of a blue light sensitive...
As a cold time-of-flight spectrometer TOFTOF’s impacts are felt across scientific areas including: biophysics, materials science; fundamental hard and soft condensed matter physics, chemistry and biology. Here we will discuss our idea for an upgraded TOFTOF. The upgrade addresses both the competitiveness of the instrument around existing scientific areas and aspires to address new...
