Kinetics of Benzene Hydrogenation Revisited in the Presence of Excess Liquid
Heterogeneous catalysis, where the reagents are either contained in a liquid medium, or are liquids in their own right, plays a significant part of the chemical industry. These... -
Studies of local order and clustering in (1-x)BaTiO3-xBiYbO3 Perovskites
We propose total scattering experiments on samples of (1-x)BaTiO3-xBiYbO3 perovskites with x = 0, 0.04, 0.08 and 0.15 to resolve issues over the local structure and degree of... -
Atomic structure of ternary tin phosphate glasses
Tin phosphate glasses are the alternative as lead-free glasses with zero photoeleastic constant (PEC) for fibers that are used in sensors of electric current. Since the binary... -
Complex structures and phase transition in mixed metal gallates: High-resolut...
Decastrontium hexagallate Sr10Ga6O19 exhibits very complex structural behaviour as a function of temperatur. The known room-temperature structure is incommensurately modulated.... -
Structure Direction from Electrons in the Presence of the 'Alkalide Option': ...
We request 5 days on SANDALS to investigate the structural effect of expanded metals in the LiNa-MeNH2 system at three different concentrations. The interplay between... -
Structures of New Oxides from Total Scattering
Our objective is to determine accurate structural models for some novel oxide materials that we have recently prepared using new synthesis approaches, each of which is formed as... -
Ba3MoNbO8.5 novel oxide ion conductor: Direct observation of oxide ion dynamics
Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating... -
In situ diffraction studies of the archetypal network glass, SiO2 at high pre...
Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of... -
Structure of Molecular Hydrogen in High Charge Pillared Clays
In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this... -
Analysis of Celtic coins from northern Italy
Our research group is working on the Celtic coinage from northern Italy and has already carried out two measurement sessions at ISIS. A selection of 25 coins (drachmas) has been... -
How Encapsulated is a Sodide? Li+Na--EtNH2 vs Li+e--EtNH2
We have recently begun to look at how large, polarisable alkalides (group 1 metal anions) are solvated in solution. This proposal aims to determine how ethylamine is able to... -
In Situ neutron diffraction of liquid gallium at elevated pressure
Gallium has a low melting point and forms a liquid just above room temperature. The melting curve has a negative slope and when pressure is applied room pressure phases will... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Environmental Apatites
Materials adopting the apatite structure are gaining an increasing importance as potential solid-oxide fuel cell electrolytes and for the chemical stabilisation of high level... -
Is CuO multiferroic at room temperatures under high pressure ?
Two recent high profile theoretical studies predict the existence of room temperature multiferroicity in CuO at high pressures. If confirmed experimentally, this would represent... -
The Local Structure of Doped α - Tricalcium Phosphate
The biomaterial potential of many calcium phosphates, such as hydroxyapatites and tricalcium phosphates (Ca3(PO4)2, TCP hereafter), have led to much literature attention over... -
Modifer Interactions in Ternary Tellurite Glasses
We wish to better understand the interaction between alkali and alkaline earth modifiers within the tellurite glass network by measuring neutron correlation functions, T(r)s,... -
A pair distribution function study of the thermoelectric skutterudites Co1-2x...
Sustainable energy-conversion technologies are important for ensuring our energy supply against declining fossil fuel reserves. Thermoelectric materials offer great potential... -
Structural behaviour of zinc in low phosphate content glasses for bone cements
Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate... -
Non destructive characterization of Nummi issued during Vth cenrury.
These measurements are aimed to identify the metallurgical and chemical characteristics of some bronze coins, called ¿nummi¿, strucked under Roman Empire, V century A.D..The...
