We request 4 days of beamtime on SXD in order to locate the protons and quantify their ordering within the structure of hopeite Zn3(PO4)2.4H2O. Hopeite is an important phase in...

Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short...

Aliphatic polyesters are the most attractive candidates for biodegradable polymers. To improve their physical properties while maintaining biodegradability, incorporating...

Photocrystallography, a rapidly developing area in dynamic structural science, allows photoinduced structural changes and transient species to be studied. X-ray techniques have...

The relationship between spin and charge correlations (stripes) continues to be one of the major issues in high temperature (cuprate) superconductivity. Under some circumstances...

Anils, N-salicylideneanilines, display thermochromism, which is thought to involve an intramolecular proton shift, but to-date the structural changes postulated to occur during...

We are performing structural investigations of a series of brownmillerites (Sr,Ca)2(Fe,Co)2O5 which display long-range modulated ordering of oxygen vacancies at ambient and high...

In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...

Metal-doped TiO2 have particular applications as in catalysis of a range of reactions as well as in luminescence materials. Our strategy is to make well-defined molecular TixOy...

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,...

Excitations in spin ice fractionalize into de-confined magnetic monopoles that interact with each other via the magnetic Coulomb interaction. Substituting rare earth ions with...

MgSO4.11H2O (MS11) is the most highly hydrated phase in the binary MgSO4¿H2O system. Whilst lower hydrates in this system have end-member analogues containing alternative...

[Rh(PiBu3)2(H3BNMe3)]BArF4 is a rare example of a structurally characterised model compound for the sigma-complex intermediate in the transition metal catalysed amine-borane...

Photocrystallography is an important technique in modern structural chemistry. The most recent and impressive developments of this technique in "small molecule" crystallography...

As part of our program in understanding hydrogen bonding systems, exploiting crystal engineering in our synthesis of complexes containing desired HB motifs, we investigate...

Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This...

Standard diffraction studies of PrBCO and YBCO show that these two compounds are isostructical. However, if any Pr/Ba disorder is present in PrBCO, the diffuse scattering signal...

Geometrical frustration in the spin ice material Dy2Ti2O7 leads to macroscopic degeneracy and the observation of magnetic diffuse neutron scattering down to the lowest...

The aim of our work is to use charge density analysis to gain insight into the process of binding relatively small anions by specifically designed small organic molecules. These...
