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... -
Search for new hydrogen, helium and neon hydrates at high pressure
This proposal is for time to search for predicted gas hydrates at high pressure. The results will provide insight into the factors governing the stability of the H-bonded... -
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... -
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... -
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... -
Probing nanophase segregation in aqueous solutions
In recent experiments we accidentally observed the onset of nanophase segregation in concentrated LiCl-water solutions by increasing dilution, in the deeply undercooled regime.... -
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... -
Q-dependence of the single particle motion in a molten alkali halide
An inelastic X-ray investigation on the collective inelastic dynamics of molten NaCl revealed the remarkable result that the acoustic-like dynamics is similar to the dispersion... -
Cs mixed cation lead perovskites
Organic-inorganic hybrid halide perovskites combine the optoelectronic properties commonly associated with high performance semiconductors with materials synthesis or processing... -
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... -
Excitation spectrum of the quantum critical S=1/2 ladder material Ba2CuTeO6
Ba2CuTeO6 is a recently discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that it is extremely close to the theoretically predicted quantum... -
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... -
Texture memory and variant selection for steel and titanium and zirconium alloys
The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with... -
