Decomposition studies of Li(1-x)NaxND2, LiNa2(ND2)3 and Li3Na(ND2)4
We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
In-situ high resolution neutron diffraction studies of cemented carbides
Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in... -
The high temperature high pressure behaviour of ammonia hydrates
Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high... -
Time Resolved Studies on Inorganic Film Formation at the Air-Solution Interface
In a recent SURF experiment on the formation of silica films templated with cat-anionic/polymer complexes we found that the film growth and evolution occurs on a faster time... -
Pd, Ni, V, Nb and Ti capping layer clamping effects in hydrogen cycling in Ca...
We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in... -
Characterising the corrosion/inhibition mechanisms of iron in different envir...
Offshore structures such as wind turbines and oil rigs generally comprise steel structuresessentially ferritic ironand are extremely prone to corrosion, a problem that causes... -
Diffusion Kinetics in Multilayer Organic Films for OLEDs
Conjugated organic semiconductors form an exciting class of materials that can be used in a variety of cutting edge technologies including organic light-emitting diodes (OLED),... -
Effect of alloying on the misfit of Ni-Ni3Al-Ni3V alloys
Ni-base superalloys have long been used in high temperature applications, including the high-demand environments of the high pressure turbines in jet engines. The remarkable... -
High Temperature Micromechanics Ni-based Superalloys: Creep, Stress Relaxatio...
In this study, in-situ high-temperature loading investigations will be performed to characterise the micromechanics of a high strength alloy 720Li, during stress relaxation in... -
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... -
Spin-Luttinger Liquid phase in a model strong-rung quantum spin ladder
Spin ladders represent a class of low-dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of the one-dimensional chain or... -
Temperature driven spin incoherence and criticality in the Luttinger liquid p...
We propose an experiment on the low energy spectrometer LET to study temperature effects on the Luttinger liquid (LL) phase on the spin ladder geometry. The spin ladder material... -
Kinetics of the ordering transition in ice Ih; crystal structure and thermal ...
Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of... -
One- and multi-magnon excitations in a strong-leg quantum spin ladder
We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well... -
Bilayer modification and charge screening by simple ions
Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported DPPC bilayer films. At low concentrations... -
Towards the development of carbonitrides as novel two-stage regenerable reage...
We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that... -
Search for the magnetic photon in a candidate quantum spin ice
Recent theoretical analyses of quantum spin ice has revealed the present of a novel magnetic excitation whose quantum properties are analogous to photons. This mode is a... -
Higher resolution inspection of the hydrocarbon pool connected with the metha...
The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously via... -
Simultaneous Microwave Dielectric Spectroscopy and Neutron Diffraction Measur...
Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...
