Measurement and Modeling of Pentane-Diluted Bitumen Phase Behaviour
The phase behavior of mixtures of bitumens and n-alkanes is a key factor in the design and optimization of solvent-assisted heavy oil recovery processes and solvent deasphalting processes. However, data and comprehensive models are lacking for these mixtures. Crude oil phase behavior is typically …

Density Fluctuations and Phase Behaviour in Non-Equilibrium Systems
… a thorough understanding of their physical behaviour. In nature, however, thermal equilibrium is more an exception than a rule. Most biological systems are inherently out of equilibrium: the self-propelling nature of organisms such as birds and bacteria, or the existence of an extinction …

Investigating the Phase Behaviour of the Alzheimer’s Amyloid-β Peptide
… state. To clarify the origins of this complex phase behaviour, this thesis aims to explore the phase space of Aβ and its potential to self-associate into a condensed liquid phase. We demonstrate that under appropriate conditions Aβ may undergo liquid-liquid phase separation, where a dense …

The use of machine vision to describe and evaluate froth phase behaviour and performance in mineral flotation systems
… the operating conditions, froth stability behaviour and flotation performance attributes need to be well understood. In addition, froth stability would need to be measured using a robust method suitable for on-line operation. Within the literature, no robust methods are available to measure …

Alterations in the phase behaviour of human γD-crystallin due to mutagenesis and chemical modification of the protein surface
… acid side-chains on the protein surface. Protein phase diagrams describe the solution conditions where phase transitions, such as liquidsolid and liquid-liquid, occur. The position of these phase boundaries is dependent on both the intrinsic characteristics of the protein and on its environment. …
