Magnetic Excitations of a Model Quantum Spin Ladder
(C5H12N)2CuBr4 is the best realisation found to date of an antiferromagnetic quantum spin ladder in the strong coupling limit. This system displays an extremely rich phase... -
Investigation into the Effect of Heating Rates on Recrystallisation Mechanism...
Electrical steels (ES) used in motors and transformers. The major challenge is to optimise themagnetic property of ES to reduce energy waste during service. The crystallographic... -
Spatial, Chemical, and Temporal Resolution of Platinum-Catalysed Benzene Conv...
This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the... -
Soft Modes in the Ferroelectric Semiconductor SbSI
Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor... -
The possibility of strongly ferromagnetic austenite in a stainless steel
It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =... -
Sensing Sulphur Dioxide in Robust Porous MOF Materials via Simultaneous Micro...
We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data... -
Is cloud water nitrate radical chemistry important in oxidising thin films on...
Projected climate change is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and reflectivity, important climatic effects.... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
In Situ Study of Excess Lithium Metal Oxides Under Charge and Discharge
The next generations of Lithium batteries require materials with an enhanced energy density. The most realistic choice for such systems are the lithium rich electrodes (e.g.... -
Arctic Cloud Chemistry: Can the Halogen "explosion" oxidize material at air-w...
The Arctic climate is strongly influenced by clouds. The oxidative processing of pollutants in Arctic clouds affects droplet size and optical properties, important climatic... -
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... -
Zero field splitting and quasiparticle breakdown in the two-dimensional quant...
In our recent NRSE experiment on the quasi two-dimensional quantum spin liquid PHCC at TRISP at FRM-II, we have found a zero field splitting (ZFS) of the magnon line of about 50... -
Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and... -
In situ diffraction studies of cathode materials for Li ion batteries
Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid... -
Ammonia adsorption studies of Li(11)BD4 and Mg((11)BD4)2
On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
Penetration and reaction of hydroxyl radical into organic films at the air-wa...
The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important climatic effects.... -
Quantum renormalisation of spin waves in a square lattice antiferromagnet
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also... -
Multiscale time resolving study of the crystallisation of polyethylene from s...
This experiment is focused on the use of the unique capability of Nimrod to study the crystallisation of polymers from solution. We wish to obtain high quality time-resolved... -
Laser-induced electron transfer in Trp-Tyr
We have recently performed a measurement of the dipeptide Tryptophanil-Tyrosine (Trp-Tyr) dissolved in deoxygenated water, illuminated by the 4th harmonic of the Nd-YAG laser...
