The myelin sheath is a multilayered membrane wrapped around axons in the vertebrate nervous system; it enables the rapid transmission of nerve impulses. It contains a set of...

Water plays a critical role in determining the structure and function of biological system. A hydration level, h~0.2 g water/g protein, is often found to be the minimum...

The miscibility of polycarbonates (PC) with polystyrene (PS) appears to be closely related to chain dynamics. Among all polycarbonates, tetramethyl bisphenol-A polycarbonate...

The proposed quasi elastic neutron scattering experiment at ISIS aims at the characterization of the dynamical properties of the series of coordination complexes Pr(BH4)3·nNH3,...

The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration...

Over the past few decades, fuel cell research has grown exponentially with the continued development of new materials and systems for automotive and stationary applications....

The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the...

We ask for 7 days on IRIS to study the quasielastic scattering in ammonium borohydride (NH4BH4). Using enriched ND4 and BD4, we aim to separate out the difference rotational and...

Magnetically modulated structures have been predicted to form close to quantum critical points in a number of recent theories, although there are no experimental examples of...

Sodium sulfate decahydrate (mirabilite) may be an important rock-forming mineral in the outer solar system, comprising a large fraction of the mantles of Jupiter's icy moons; it...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

The dynamics of liquid aluminium will be measured at the structure factor maximum up to twice the melting temperature. We are searching for changes in dynamics which should...

In Ce-based heavy fermion materials, there is competition between the interactions which lead to a magnetically ordered arrangement of the Ce magnetic moments, and the...

The detailed functional characterization of an outer membrane for C. glutamicum is a major challenge for the future since it raises several questions regarding the resistance of...

The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied...

It is proposed to investigate the torsional dynamics of the ¿NH3+ group of glycine-d2 in its three polymorphic forms using quasielastic neutron scattering (QENS). This study is...

We propose to conduct inelastic neutron scattering (INS) measurements on deuterated polycrystalline samples of the magnetic molecule {Mo214V30}, to determine the low-lying...

ZrW2O8 is the classic example of a material exhibiting negative thermal expansion (NTE), i.e. lattice shrinkage on warming. The origin of this behaviour has been controversial...

The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh...

The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy...
