Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
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... -
Investigations of atomic and intermediate-range structure in model membranes
This proposals aims to investigate the atomic and intermediate range structure in model membrane environments. By beginning with a disperse system of a phosphocholine lipid in... -
Search for Antiferromagnetic order in ZrMn2
Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type... -
Insight into the atomic and intermediate level structure of spherical and rod...
Here we propose to look at the structure of two phosphocholine lipids, and their larger scale structures in aqueous solution. Depending on the length of the fatty acid chain in... -
Probing atomic and mesoscale structural correlations in 1-alkyl-3-methylimida...
This proposal aims to extend our understanding of ionic liquid structure by performing measurements that will complement the data previousy collected on SANDALS. We propose to... -
Structural distortions and magnetism in the layered oxide sulfide Sr2MnO2Cu1.5S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to correlate the magnetic structure and the crystal structure of... -
Low temperarature structure of Sr2CoO2Cu1.85S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to examine the differences between a sample of Sr2CoO2Cu1.85S2... -
Accurate H atomic parameters for charge densities in polymorphic materials
Polymorphism is a common feature of many molecular materials The "Holy Grail" would be the ability to predict the appearance of polymorphism in a particular molecular system,...
