Understanding an-harmonic behaviour in lyophilised proteins - a high energy r...
By combining OSIRIS/IN16 elastic window and QENS data we better understand dynamics in lyophilised apoferritin. This complimentary approach reveals that the observed decrease in... -
Microscopic dynamics of water associated to phospholilipd/polysaccharide nano...
In recent years nano- and microparticles composed of polymeric or lipid material have been proposed as drug carriers. Their use allows the modification of the biopharmaceutic... -
Revising the onset of anharmonicity in proteins
Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al... -
Unravelling the ageing mechanims of dry seeds: molecular mobility within biol...
Faster-than-expected ageing is observed in some seeds (e.g. orchids, coffee, citrus, willows) stored dry at -20°C, the standard temperatures of seed banks. This ageing has been... -
Structural relaxation in LiCl 6D2O
We propose to measure the structural relaxation in this prototype glass former. The structural ralaxation time will be obtained at the structure factor maximum. We suppose that... -
Cation substitution in synthetic meridianiite (MgSO4.11D2O): phase behaviour ...
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... -
How molecular solids prepare for phase transitions: The phase transition in o...
Oxalyl chloride (mpt. 260 K), forms an ordered phase at low temperature, but a disordered phase between 250 K and the melting point. In previous beamtime we aimed to carry out... -
Diamond nanoparticles: a bright future for nano-composites?
Conductive polymers (CP) show desirable physicochemical properties, with CP-based nanocomposites being manufactured for various applications i.e. sensors The filler particles... -
Investigation of the Dynamic Mechanism of Xylanase by QENS
In this proposal we will pioneer the use of QENS in combination with molecular biology mutagenesis and in silico design to guide the re-engineering of a glycoside hydrolase,... -
Water dynamics in dental zinc cement by quasi-elastic neutron scattering
Zinc phosphate cements (ZPCs) are used in dentistry. Cement formulation (liquid+solid) is largely empirical because of lack of information on the exact chemical nature of the... -
Water diffusion mechanism in hydrated amorphous calcium carbonate
Calcium carbonates are highly important in geochemistry and especially in biomineralization. In nature, organisms can form each of the anhydrous polymorphs selectively for... -
Structural phase diagram of hydrated silks
The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich... -
QENS Study of Proton Diffusion in Metal-Organic Framework Materials
The development of new functional metal-organic frameworks (MOFs) as complex proton conductor is receiving increasing attention worldwide. We aim to develop new solid proton... -
Phase Transitions and Orbital Ordering in SrRu1-xCuxO3.
This proposal seeks to establish the importance of orbital ordering on the stability of the tetragonal phase in Cu doped SrRiuO3. Orbital ordering is believed to be a... -
Melting point dynamics of Confined fluids
This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is... -
The dynamics of wild type and mutated myelin proteins P2 and CNPase.
The myelin sheath is a multilayered membrane wrapped around axons in the vertebrate nervous system; it enables the rapid transmission of nerve impulses. It contains a set of... -
The dynamical transition in dry proteins?
Water plays a critical role in determining the structure and function of biological system. A hydration level, h~0.2 g water/g protein, is often found to be the minimum... -
Quasielastic Neutron scattering Study of Water dynamics in Hydrated Cellulose...
The separation membrane is a key component in Polymer electrolyte fuel cells. It must be both an ionic conductor and an electronic insulator. Cellulose nanofibrill membranes... -
Cation reorientation dynamics in a metal formate perovskite
Hybrid metal-organic perovskites are promising functional materials, but the complex interactions between organic cations and the framework surrounding them are difficult to... -
Ligand-field characterization and U-Pt bonding in uranium-based heterometalli...
We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and...
