X-ray Radiation damage to DNA at the atomic level
The interaction of ionizing radiation such as X-rays with biological samples causes damage to the samples. Recent work from our group with various protein crystals, peptides and... -
Ordered structures in the new Topological Insulators
We propose to investigate the structure of the new ¿ordered¿ phases within the Bi2Se3-Bi2Te3 phase diagram of the newly discovered Topological Insulators. The bulk properties of... -
A single-crystal diffuse scattering study of Ferrocene
We propose here a detailed study of the diffuse scattering of ferrocene with the key objective of investigating the origin of the cyclopentadienyl (Cp) ring disorder in this... -
Proton transfer in croconic acid
Croconic acid has recently emerged as the first example of an above room-temperature organic single component ferroelectric. Our goal is to determine its crystal structure at... -
The structure and hydrogen bonding of poly(pyridobisimidazole) (PIPD)
PIPD is a polymer with unusual tensile and compressive strength. Inter and intramolecular H-bonding interactions are thought to be responsible for these properties. PIPD is also... -
Diffuse scattering studies of squaric acid in an applied electric field
Organic ferroelectric compounds such as KH2PO4 and squaric acid, have attracted much interest in the past due to their potential in applications [1]. This interest has been... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
Diffuse scattering study of single crystal PrBa2Cu3O7-x
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... -

Photocrystallography is an important technique in modern structural chemistry. The most recent and impressive developments of this technique in "small molecule" crystallography... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the... -
Influence of superstructures on rich transport properties of lithium cobaltate
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... -
Diffuse scattering in the paraelectric phase of titanite
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... -

Neutron photocrystallography study of [Ni(dppe)(n1-NO2)Cl]
Photocrystallography is a rapidly developing technique in modern structural chemistry which will result in a paradigm shift in the way that the crystallographic method is... -
3D neutron TOF diffraction imaging
We propose to use SXD for mapping the crystallographic phases in an extended 3D benchmark object. The phase distribution will be reconstructed using a geometrical aberration... -
Ab-inito lattice dynamics and thermal diffuse scattering in amino acids and p...
We propose to simultaneously collect diffuse and Bragg scattering in the amino acids L-Serine, L-Alanine, and their joint dipeptide L-Alanine-L-Serine hydrate and ask for 8 days... -
Radiation induced hydrogen abstraction - A combined X-ray and neutron diffrac...
X-ray induced radiation damage drastically limits the structural information accessible in diffraction experiments from macromolecules at 3rd generation synchrotrons. Relatively... -
