Quasi-elastic neutron study of the organic cation dynamics in the halide pero...
Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this... -
Aza-crown-stabilized Alkali-Alkalide Systems: Solvent and metal effects on di...
We request 4 days on IRIS to investigate the diffusional and rotational dynamics of the alkalide forming, fully methylated aza-crown hexamethyl-hexacyclen (HMHC) in... -
Oxygen Positional Disorder in the "Empty" Tetragonal Tungsten Bronze Ba4La0.6...
Ferroelectric tetragonal tungsten bronze oxides (TTBs) have been extensively studied for their application dielectric and non-linear optical devices. TTBs often exhibit... -
QENS studies of the interaction of propene with ZSM-5
Fluidised Catalytic Cracking (FCC) units are one of the major conversion units in modern petrochemical refineries. ZSM-5 additives are used in FCC units to convert gasoline... -
Investigation of the Dynamic Mechanism of Reflectin Color Change by QENS
Reflectin, so named because of its high refractive index, is a protein expressed exclusively in cephalopods and forms reflectors responsible for dynamic iridescence and... -
Jump diffusion of small molecules in polymers influence of grafting on the ...
The concept of diffusion of light gases through polymers is a widely used in a variety of commercially available materials - food packaging materials, solar cell encapsulants,... -
Quasi-Elastic Neutron Scattering of Green Dioptase to Unravel the Motion of t...
Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D... -
Temperature dependence of phonon modes in protonated (H2O) and deuterated (D2...
Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6... -
Neutron Scattering, Agricultural Wastes, Concrete & Water mobility: What can ...
In recent years, the research related to agricultural wastes aiming to evaluate their potential for recycling as well as the elimination of the landfills increased dramatically.... -
High pressure behaviour of ammonium carbamate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Dynamics of PDMS-g-PDMS bottlebrush polymers
Bottlebrush polymers, backbone with long side chains, are very interesting regarding their architecture, which is different from well known linear polymers. Not only the... -

Molecular weight dependence of 2D-confined dynamics in glass-forming systems
We seek to explore the dynamics of glass forming systems upon extreme 2D-confinement. These experiments are motivated by preliminary experiments on oligomers and macromolecules... -
Diffusion studies using methane as a probe molecule to investigate the methan...
Methanol-to-Hydrocarbons (MTH) is an important industrial reaction. It is thought to work through a 'hydrocarbon pool' mechanism where the hydrocarbons retained within the... -
In-gap excitons in CaFe2O4
The proposal requests time to measure the low-energy excitations in CaFe2O4 as a function of temperature. Previous experiments have observed a series of in-gap states at high... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism... -
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... -
Magnetic ordering and structure phenomena in the rare-earth CeRu2Al10 compound.
This proposal is for crystal-structure (on HRPD) and magnetic ordering (on WISH) studies on the local-moment compound CeRu2Al10. It follows from our recent neutron studies at... -
Decoupling effect between protein and water
Water plays a critical role in life. A hydration level, h ~ 0.2 g water/g protein, is found to be the minimum for the dynamical transition in protein at Td ~ 200 K. This... -
Studying dynamics of water on graphene by quasi-elastic neutron scattering
Graphene-based materials have unique structural and physiochemical properties, and have been exhibited as efficient working substances to filter salts in saline water....
