We propose to measure the spin fluctuations in Na0.44MnO2 using the MARI chopper spectrometer. Na0.44MnO2 is derived from alpha-NaMnO2 and is a tunnelled structure. Preliminary...

The purpose of this investigation is to investigate the electric field dependence of the dynamics of the melting transition of bulk and confined water with an applied electric...

Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in...

We propose measurements of the Bose-Einstein Condensate (BEC) fraction n0 of solid helium confined in porous media. A superfluid fraction in solid helium in Vycor, in aerogel...

It is well known that water is the medium in which the overwhelming majority of biological processes take place. In cell membranes water molecules are thought to be essential to...

The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant...

Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through...

We propose a comparative study of the high-frequency optic-like mode and Boson peak modes observed in the vibrational density of states (DOS) in the glass phase of the two model...

We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to...

Inelastic neutron scattering has proven to be reliable tool to investigate the phonon structure of hydrides. E.g., it was shown that the vibrational structure of Ca(BH4)2 has a...

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

In orbitally degenerated triangular system it is predicted that orbital ordering and associated local magnetic trimerization to remove frustration. In BaV10O15 lattice...

The non conventional d-wave superconductivity in Heavy Fermion compounds seems to be triggered by spin fluctuations, which is in strong contrast to conventional...

Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a...

Nanowires can be used for devices based on thermoelectrics and to convert the heat into electrical current. The material design challenge here is to create the materials where...

Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon...

Graphite intercalation compounds (GICs) have potential as hydrogen storage materials, from direct physisorption of H2 or as a high surface area nanostructured host for metal...

This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of...

We propose to use MARI to look at the full rotational spectrum of H2 in Ni-MOF-74 obtaining the full momentum distribution for H2 only at the Ni metal site and one with partial...

The applicants have used a recent EPSRC award to develop protocols by which INS can be used to investigate methane reforming catalysts. That work is now complete and we have...
