Hydrogen bonding in monoclinic jarosites
Jarosite minerals are of great importance to a range of mineral processing and research applications, as well as significant to the understanding of the environmental history of... -
Magnetism in a charge doped cuprate chain
We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing... -
Proton Delocalization in Liquid Hydrogen Chloride
Liquid HCl has attracted numerous studies focusing onto the role played by hydrogen bonding on the dynamical properties of this weakly associated liquid. Previous computational... -
Morphology of poly(ethylene-oxide)-ionic liquid mixtures: the role of hydroge...
We propose to explore the morphology of binary mixtures of poly(ethylene oxide), a biomimetic macromolecule, and two different ionic liquids, differing in their hydrogen bonding... -
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... -
Proton ordering and hydrogen bonding in the hydrous zinc phosphate hopeite, Z...
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... -
Framework flexibility and host-guest hydrogen bonding in the metal-organic do...
The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the... -
The Effect of Pressure on the Crystal Structure of Serine Hydrate
Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,... -
Contributions of ¿NH3+ torsions to phase transitions of glycine
It is proposed to investigate the torsional dynamics of the ¿NH3+ group of glycine-d2 in its three polymorphic forms using quasielastic neutron scattering (QENS). This study is... -
Hydrogen bonding in amorphous formic acid
Formic Acid (FA) is a simple model for rotational isomerism, and it presents four different hydrogen bonding sites. In a recent study, we have elucidated the structure of FA in... -
Cryopreservation in biological systems: glutamine as a model system to study ...
Many living organisms have developed mechanisms that protect them from extremeenvironmental stresses such as freezing and pressure. One common mechanism involvesaccumulation of... -
Crystal structures of methanol mono-ammoniate (CD3OD.ND3) and methanol hemi-a...
Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the...
