Local magnetic structures of YBCO high-Tc superconductors from neutron total ...
Understanding high-temperature superconductivity is a major aim of condensed-matter science, which is of fundamental importance and may ultimately allow the design of materials... -
The Structure of Alkaline Earth Germanate Glasses
We request GEM beamtime to study the structure of a series of calcium germanate glasses. The changes in coordination number and properties which occur in alkali germanate... -
A Structural Study of Tungsten Tellurite Glasses
Tungsten Tellurites are being used to make optical fibres that transmit light into the mid infra red. However, not much is know about the structure of these glasses. We wish to... -
Isotopic Mass Contrast Study of Silica Glass
We wish to perform neutron diffraction measurements on glass samples of SiO2 and 30CaO.70SiO2 containing both natural oxygen and 18O. The oxygen scattering lengths are almost... -
Total scattering measurement of EMT framework zeolite: does it obey Lowenstei...
Zeolites are meso- and nano-porous framework materials with applications in many industries. The zeolite framework consists of corner-sharing tetrahedral units. The catalytic... -
Structural studies of modified iron phosphate glasses to understand key struc...
We intend to use neutron diffraction and x-ray diffraction to investigate the structure of potassium and barium iron phosphate glasses, which are potential candidate systems for... -
Breaking Zachariasen rules - the structure of barium zirconium fluoride glasses
Glass is an essential material with applications that are dominated by oxides, but fluoride glasses (based on barium zirconium fluorides, "ZBLAN" glasses) have key applications... -
Investigating the structure of novel chloride-containing bioactive glasses fo...
A range of novel chlorine-containing bioactive glasses have recently been developed at Queen Mary University of London for dental and orthopaedic applications. At present little... -
Precise Determination of the Cation Distributions of Oxide Ionic Conductors B...
We designed and synthesized a series of new oxided ionic conductors Ba3M1+xTi1-xO8+x (M = Mo and W), which adopt a hybridized structure with the features of 9R perovskite... -
Reversible ammonia storage; Structure and stoichiometry of defect imide-amide...
In this proposal we will study the average and local structure changes in Li-N-D imide-amides formed as intermediates during the ammoniation of Li3N and deammoniation of LiND2.... -
Structure-Property Relationships in Photoluminescent Platinum and Palladium C...
The average and local structure in the mixed-metal cyanides, Ni1/2Pt1/2(CN)2, Ni1/2Pd1/2(CN)2 and Pd1/2Pt1/2(CN)2 will be determined to give the M-C and M-N bond lengths, the... -
Caesium sorption in Cu2[Fe(CN)6], a potential nuclear waste cleanup material
Caesium-137 is among the most important hazards associated with low-level nuclear waste. Among the most promising materials for scavenging Cs+ ions from waste solutions are the... -
Atomic structure of barium tin phosphate glasses
Tin phosphate glasses are an alternative as lead-free glasses with zero photoelastic constant (PEC) for fiber applications. A second modifier oxide is added for improving the... -
The environment of lithium in an invert glass
We request beamtime to study lithium silicate glasses over a very wide composition range from 20 to 65 mol.% Li2O, made by rapid quenching. For the higher Li2O contents, the... -
A systematic survey of solute-solute contacts in bulk metallic glasses
A clear description of the local atomic structure as a function of the composition is essential to guide discovery and development of new metallic glasses. The efficient cluster... -
Sodium chalcohalide glasses for battery applications
Lithium batteries provide the highest energy density which makes them ideal candidates for future generations of portable electronics and electric vehicles. The increasing... -
Investigating the structure of novel fluoride-containing bioactive glasses fo...
We propose to study a range of novel fluorine-containing bioactive glasses with potential applications in dentistry and orthopaedics. At present little is known about the atomic... -
Short range order Ge-S and Ge-(Ga,Sb)-S glasses
Ge-(Ga,Sb)-S glasses are widely used in infrared optics. Despite the practical importance their short range order is still not understood completely. The main problem is that... -
