Stochastic Cation Dynamics in Photovoltaic Hybrid Perovskites under Pressure
Methylammonium lead iodide (MAPI) is one the most promising materials for photovoltaics. Notwithstanding the above, access to its phase diagram and the underlying structural... -
Determining the interaction between water and carbon dioxide in smectite clay...
Interactions between CO2 and clay minerals have attracted interest in the scientific community recently. This is partly motivated by the presence of large amounts of clays in... -
Comparison of Dynamical Behaviour in MAPbX3 and FAPbX3: How Do They Differ ?
Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a... -

Origins of flexibility in a zero-thermal-expansion framework
Our proposal is to use neutron total scattering on GEM to study framework flexibility and the phenomenology of the displacive phase transition in the cyanide-containing... -
Probing hybridization strength and homogeneity of valence mixing in magnetica...
The compounds we want to study belong to the well-known tetragonal RM2X2 family (R: rare earth, M: d element, X: Ge, Si). In EuCu2(SixGe1-x)2, the Eu valence changes, as a... -
INS on methane dynamics absorption in dipeptides
The dipeptides are a class of organic molecules that form hexagonal crystalline structures (space group P61) with one-dimensional chiral channels of tunable pore diameters in... -
Investigating the magnetic structure of the solid solution PrCr(1-x)MnxO3
Rare-earth (A= La, Ce, Nd, Pr) orthochromites (A CrO3) and orthomanganites (A MnO3) are of interest due to the number of unusual physical properties they possess, displaying... -
PROBING DRUG PHARMACODYNAMICS BY INS - THE EFFECT OF CISPLATIN-LIKE ANTICANCE...
Cancer is a growing health problem worldwide, and thus the development of effective chemotherapeutic approaches is crucial for improving human health. Much effort has been put... -
High pressure behaviour of ammonium carbonate monohydrate
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... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Spin orders in CaxMn2-xFeReO6 double perovskites
New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =... -
Dynamics within the Plastic Crystal Phases of Hydrogen Chloride
Hydrogen chloride exhibits a complex phase diagram account made of its simple molecular structure. Three crystalline phases are known to exist at ambient pressure below its... -

Neutron Total Scattering Investigation of Temperature Driven Transitions in L...
This proposal is concerned with determining the local structure of LaCoO3 and observing changes within this as the material undergoes some well characterised temperature driven... -
Phase Diagram of Ba1-xKxFe2As2
In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole... -
Structure Direction from Electrons in the Presence of the 'Alkalide Option': ...
We request 5 days on SANDALS to investigate the structural effect of expanded metals in the LiNa-MeNH2 system at three different concentrations. The interplay between... -
The search for long range exchange interactions in the S=1 square lattice ant...
