Monte-Carlo Simulation of Diffusion as an Aid to Interpreting Quasi-elastic Neutron Scattering from Lattice Gas Systems with Diffusion on Multiple Time-Scales (2022)
Thesis
Swales, J. Monte-Carlo Simulation of Diffusion as an Aid to Interpreting Quasi-elastic Neutron Scattering from Lattice Gas Systems with Diffusion on Multiple Time-Scales. (Thesis). University Of Salford

Pd and Pd-Ag have recently found application in hydrogen processing technologies, both in terms of purification membranes and isotope-separation systems. Direct measurement of the diffusion processes in these systems is provided by quasi-elastic neut...

Crossover between liquid-like and gas-like behaviour in CH4 at 400 K (2017)
Journal Article

We report experimental evidence for a crossover between a liquid-like state and a gas-like state in fluid methane (CH4). This crossover is observed in all of our experiments, up to 397 K temperature; 2.1 times the critical temperature of methane. The...

On the high-pressure phase stability and elastic properties of β-titanium alloys (2017)
Journal Article

We have studied the compressibility and stability of different β-titanium alloys at high pressure, including binary Ti–Mo, Ti–24Nb–4Zr–8Sn (Ti2448) and Ti–36Nb–2Ta–0.3O (gum metal). We observed stability of the β phase in these alloys to 40GPa, well... Read More about On the high-pressure phase stability and elastic properties of β-titanium alloys.

Synthesis of pure lithium amide nanoparticles (2013)
Journal Article
Baldissin, G., Boag, N., Tang, C., & Bull, D. (2013). Synthesis of pure lithium amide nanoparticles. European Journal of Inorganic Chemistry, 1993-1996. https://doi.org/10.1002/ejic.201201535

Deprotonation of ammonia with n-butyllithium offers a facile synthetic route to produce pure lithium amide exhibiting fine granularity, which facilitates the complete thermal decomposition to lithium imide at a relatively low temperature of 600 K. Sy... Read More about Synthesis of pure lithium amide nanoparticles.

n-Diamond : Dynamical stability of proposed structures (2013)
Journal Article

A number of experimental works, mainly under extreme conditions, report a carbon phase with the same reflections as diamond but showing additional reflections that are forbidden for diamond. The crystal structure of this phase, called n-diamond by Hi... Read More about n-Diamond : Dynamical stability of proposed structures.

Low frequency sound propagation in activated carbon (2012)
Journal Article

Activated carbon can adsorb and desorb gas molecules onto and off its surface. Research has examined
whether this sorption affects low frequency sound waves, with pressures typical of audible
sound, interacting with granular activated carbon. Imped... Read More about Low frequency sound propagation in activated carbon.

The pressure–temperature phase diagram of MgH2 and isotopic substitution (2011)
Journal Article

Computational thermodynamics using density functional theory ab initio codes is a powerful tool for calculating phase diagrams. The method is usually applied at the standard pressure of p = 1 bar and where the Gibbs energy is assumed to be equal to t...
