The chemisorption of hydrogen over a high surface area cobalt catalyst: An IN...
In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of... -
Evolve of the Spin Waves in Rb0.8Fe1.6Se2 at High Temperature
The newly discovered AxFe2-ySe2 (A=K,Rb,Cs) compounds have attracted great interests because of their parent compounds are insulators instead of being metallic [2-6].... -
Pd, Ni, V, Nb and Ti capping layer clamping effects in hydrogen cycling in Ca...
We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in... -
Magnetic structure of new manganite TlMnO3
Recently synthesized new perovskite TlMnO3 is distinct in respect of crystal structure (space group) and orbital ordering from those of the previously known trivalent perovskite... -
Copy of: Division of the supercritical fluid state into liquid- and gas-like ...
In recent years, the long-standing belief that beyond the critical point, matter exhibits no clear transition between liquid-like and gas-like states has been questioned. A line... -
Diffusion in a zeolite under flow conditions
Quasielastic neutron scattering is often used to measure the diffusion of organic materials inside the pores of catalysts. Although generally performed in a sealed system, a... -
One- and multi-magnon excitations in a strong-leg quantum spin ladder
We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well... -
Study of structural and phase transitions of carbon dioxide confined in the n...
The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental... -
Understanding anaesthetics: Ethanol partitioning into lipid membranes, effect...
Ethanol plays an important role in the human metabolism. It is in particular known to act as a drug enhancer by increasing trans-membrane permeability, and as an anesthetic.... -
Study of the dynamics of a multi-component polymer blend using neutron polari...
Dynamics of multicomponent mixtures such as polymer blends are typically studied with QENS and deuterium labelling. Difficulties arise in the data analysis if the coherent... -
Na-ion diffusion mechanisms in NaxFe1/2Mn1/2O2 cathode materials
NaxFe1/2Mn1/2O2 has been identified as a potential cathode material for Na-ion batteries since it has comparable electrochemical performance to commercially available Li-ion... -
Dynamic Nuclear Polarization in GaAs by electrical spin injection
We propose to measure the dynamic nuclear polarization in a GaAs-based structure caused by electrical injection of a spin-polarized current using polarized neutron... -
PNR determination of the magnetic depth profile in uniformly ion irradiated F...
FeRh with a meta-magnetic (from antiferromagnetic to ferromagnetic) phase transition at around 100°C has real potential for a range of applications including data storage media,... -
Phonon dynamics in liquid gallium
We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for... -
Na-Dynamics in Solid Ionic Conductors: 11Al2O3-Na2O and Na2Ti3O7
We would measure vibrational spectra as well as quasielastic neutron scattering (QENS) spectra for beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of phonon spectra... -
