In recent years, the investigation of metamagnetic properties of first order magnetic systems has become revolutionary. The rare-earth based compound Nd5Ge3 exhibits a magnetic...

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...

We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4...

Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these...

In our previous experiments we have investigated the surface properties of liquid 3He - 4He mixtures by neutron reflection. We have shown that in broad temperature range there...

Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice...

Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk...

The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from the n=8, 10 and 12 homologues of the nCB series...

We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a...

Hydrogen binding to coordinatively unsaturated metal sites (CUMCs) in metal-organic frameworks (MOFs) has been extensively studied in our group using neutron powder diffraction...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent muSR studies of Au NPs encapsulated in mesoporous...

We request 5 days on NIMROD to characterise the pressure and temperature dependent properties of amorphous icy particles generated in liquid ethane, as they will be used in...

This proposal is a continuation of RB1000003 and RB1110113. The aim of the present experiment is to gain further insight into the mechanism of benzyl alcohol oxidation using...

Sodium cobalate has emerged as one of the best thermoelectric materials. Our previous neutron Laue diffraction studies on SXD have found ordered arrays of multivacancy clusters,...

LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as...

There are two contributions to the rms roughness of a polymer-polymer interface; i) the so-called ¿intrinsic interfacial width¿ due to mixing of the polymers at a molecular...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Alloy catalysts are commonly employed for selective hydrogenation of organic molecules due to their enhanced selectivity than individual components but their structural and...

The proposing team is interested in exploring the low-temperature quantum "rattling" dynamics of helium atom(s) trapped in water-based cages (namely the so-called "clathrate...

Under confinement in porous media, helium-4 excitations develop a complicate behaviour and, in addition to a bulk-like spectrum, a second branch emerges due to helium-4 atoms in...
