Protein folding is a fundamental process in molecular biology. Apomyoglobin (apo-Mb) – myoglobin without the heme group – is less stable then Mb and can be trapped in different folded, partially folded molten globules und unfolded states under equilibrium conditions depending on the chosen solvent conditions. I will present an investigation on the dynamics of the protein in its different...

We present a novel experimental device to perform simultaneous incoherent quasi-inelastic neutron scattering with dielectric spectroscopy at high pressures. The cell has been designed to be utilized in a temperature range of 2-315 K and for a maximum pressure of 500 MPa. High tensile aluminium alloy was selected due to its low neutron absorption and incoherent scattering cross section. In this...

I, for the first time used a backscattering spectrometer is IRIS, at ISIS facility, UK, way back in 1990, to study quantum rotational tunnelling of NH4+ ions in mixed ammonium metal-alkali halides, during my stay at ISIS facility. It was found that at very low concentration (c) of the NH4+ ions behave like 'almost' free rotors. The spectra were described successfully by distribution of...

MEH-PPV (poly[2-methoxy-5-(2_-ethylhexyloxy)-1,4-phenylenevinylene] is one of the most common conjugated polymers which continues to be of high interest in the area of polymer-based solar cells research, because of its good thermo-mechanical properties, stability, ease of processing, low-costs etc... We present recent quasi-elastic neutron scattering measurements of this electroluminescent...

MARS is an indirect TOF backscattering spectrometer at SINQ, PSI. MARS can be instrumentally best compared to the IRIS spectrometer at ISIS, but it was optimized for complementary research, i.e. high energy resolution and clean spectra in the inelastic region (magnetism). The secondary instrument consists of alternating 10 inelastic units and 12 diffraction detectors, arranged symmetrically at...

High-temperature polymer electrolyte fuel cells (HT-PEFC) are promising electrochemical energy converters. Because of the high operation temperature of 160° - 180°C HT-PEFCs have a high CO tolerance [1]. The fundamental investigation of the proton conductivity will help to optimize performance and increase sufficiency of the fuel cells. For example, the understanding of the proton diffusion...
