Hydrogen production from ammonia using lithium imide: an isotope study
We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron... -
Crystal symmetry change at the magnetic transition in MnB and FeB compounds p...
The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However,... -
Magnetic excitation spectrum of a potential spin liquid candidate
PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions. There are 3 potentially strong interactions, the first neighbor interaction couples the magnetic ions into... -

Multiferroic materials exhibiting at least two ferroic orders are the subject of extensive research due to many potential technological applications. Bismuth ferrite (BFO) is by... -
Phase transitions in Sr-doped multiferroic bismuth ferrite
Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
Deuteration-induced phase transition in a multiferroic framework material
The hybrid organic-inorganic perovskites are of great interest as functional materials, because they combine the well-established perovskite topology with new physics and... -
In Situ High Pressure NMR study of the Direct Synthesis of NaAlH4
NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a... -
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... -
The Effects of Zeolite Expansion on Molecular Diffusion
Zeolites are porous materials that can absorb other molecules, which makes them useful in a number of fields. When they absorb molecules, they change size, either shrinking or... -
Non-stoichiometry in (Na1/2Bi1/2)TiO3: from a Pb-free piezoelectric to fast i...
4 days are requested on HRPD to collect Neutron Diffraction (ND) on a carefully designed series of (Na1/2Bi1/2)TiO3-based perovskites (NBT) that exhibit a switch in electrical... -
Dynamical Perovskites
Hybrid perovskites, composed of an organic cation, inside a post transition metal halide framework, have emerged as simple, low cost solar cell materials, with power conversion... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite.... -
Neutron Scattering and Structural Measurements of CO2 and CD4 Adsorption in M...
Shale is an increasingly viable source of economic quantities of natural gas worldwide. Most of the gas is contained within the fine pores, thus characterizing accessibility and... -
Thermoelastic Properties of Thermoelectric PbSe I HRPD
We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste... -
Investigation into the reversibility of TiCl4 doped NaALH4
Hydrogen Storage still remains the technology bottleneck for a more widespread use of hydrogen. Solid complex hydrides such as amides, alanates and borohydrides have been... -
Has residual solvent an impact on the dynamics of PMMA ultra thin films?
Polymeric films thinner than a 100 nm exhibits a variation of the glass transition temperature of a few tens of degrees and can brake up into discrete islands when heated near... -
Thermal expansion of hexa-halogenated benzenes: C6Cl6, C6Br6, C6I6.
The aim of the present proposal is to complete a systematic study on the effects of isotopic and chemical substitution on the thermal expansion and vibrational properties of...
