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... -
Clarifying the role of acid and base dopants in the hydrogen-ordering phase t...
Using ISIS facilities, our team has discovered three new phases of ice: ices XIII, XIV and XV. These phases form in the presence of small amounts of hydrochloric acid. Yet, the... -
QENS Studies of Diffusion of NH3 Molecules in Porous MOF Materials
The development of new porous metal-organic frameworks (MOFs) is receiving considerable attention worldwide owing to their potential for gas storage, separation, and... -
The Effect of Framework Structure and Composition on Controlled Drug Release ...
The mobility of beta-blocker and angina/hypertension drug atenolol in zeolites FAU and BEA will be probed using QENS to understand the importance of fundamental... -
An Investigation of Magnetic Transitions in NdMn1-xCoxAsO0.95F0.05 (x = 0.03,...
We have recently reported colossal magnetoresistance (CMR) in NdMnAsO0.95F0.05. The CMR in NdMnAsO1-xFx arises due to competition between a strongly correlated antiferromagnetic... -
Neutron scattering investigation of the influence of high hydrostatic pressur...
Amyloid fibrils are highly organized filamentous structures formed by the self-assembly of polypeptides. This proposal is to study the effect of pressure on the structure of... -
The intermediate stages of hydrogen disorder to order phase transitions in ice
In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we... -
Understanding Structure-Direction of Organic Molecules in Zeolite Synthesis t...
The mobility of zeolite structure directing agent (SDA) 1,2,3-triethylimidazolium (TEI) when still confined in zeolites MFI and STF after synthesis will be measured using... -
Study of gas absorption in MCM41.
We have studied the absorption of nitrogen gas in MCM41 on NIMROD at a pressure of 1 bar and at temperatures to 87K (A K Soper and D T Bowron, Chem. Phys. Lett., DOI:... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Investigating the diffusion of E-caprolactam in hierarchically-porous catalys...
Caprolactam (CL) is a high-value chemical and precursor to nylon-6. Industrially, a harsh, liquid-acid catalyst effects the Beckmann rearrangement of C6-oxime to CL, but the... -
Investigating the diffusion of cyclic oximes in hierarchically-porous catalys...
Caprolactam (CL) is a high-value chemical precursor to nylon-6. On an industrial scale an aggressive liquid-acid catalyst is used to transform C6-oxime to CL. Due to... -
Me-ND311BD4: a temperature dependent study of its crystal structure and decom...
We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to... -
Rosseinsky programme access GEM
The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural... -
