We wish to better understand the interaction between the alkaline earth modifiers and the tellurite glass network. The aim is to relate structural changes in the glasses with...

Neutron diffraction offers one of the most interesting and meaningful methods for non destructive quantitative determination of the phase composition of materials. However, it...

For total diffraction measurements using neutrons it is important to correct the data for inelasticity effects, especially for samples containing light atoms. Conventionally...

Alkali borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4)and [GeOn] (n = 4, 5, 6) polyhedra can coexist. Equilibrium between these structural units has...

The two Helmets subject of this proposal are kept in the Museo Archeologico Regionale Lilibeo - Baglio Anselmi of Marsala (Trapani, Italy). They were found in the seabed of Capo...

In this proposal we wish to study in situ formation of methane hydrates in surfactant solutions. The broad aim of this research is to enable us to understand how we can...

Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour...

Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure....

We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions...

This proposal sets out to investigate the high pressure behaviour of the double perovskitematerial with the chemical formula La2NiMnO6. The properties of this and related...

20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid....

The present proposal concerns the archaemetallurgical investigation of Etruscan mirrors. TOF-ND, NRCA and transmission measurements (Bragg edge) will be carried out on INES in...

Thermoelectric materials provide an alternative route for refrigeration and power generation bydirect conversion between thermal and electrical energy. With high chemical...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...

We wish to better understand the evolution of the tellurium environment in glasses with the addition of modifier oxides. The aim is to relate these structural changes to the...

In a proof-of-concept beamtime award (RB1220486) we studied the process of platinum-catalysed benzene hydrogenation in the pores of MCM-41 using standard neutron diffraction...

Our objective is to determine structural models for some complex, mixed-metal oxide phases that are as complete as possible using analysis of PDFs produced from total neutron...

FeF2 is a conversion reaction material that undergoes a reaction with lithium: FeF2+2Li++2e-<->2LiF+Fe, which results in a high theoretical capacity, 571 mA/g....

Tellurite glasses exhibit strong non-linear properties which are related to the asymmetric environment of the Te atom. The non-linear optical effects are strongest when the Te...

Niobium is one of the candidates for causing strong non-linear optical properties in oxide glasses. Recently, Raman gain experiments on niobium phosphate glasses were quite...
