Sorption at Liquid-Liquid Interfaces

The transfer of a solute from one phase to another is a process of considerable interest from both a fundamental and industrial point of view. In the Sorption at Liquid-Liquid Interfaces theme the research is aimed at understanding interfacial phenomena in liquid-liquid extraction.

Key Research Areas

  • Development of analytical techniques for the measurement of metal ion transfer across the oil/water interface
  • Measurement of metal ion extraction kinetics in micellar systems
  • Study of ionic liquids as alternatives for volatile organic carbons
  • Development of improved contacting equipment for two phase systems

Ultrasonics

The ultimate goal of the ultrasonics research team is to better understand the fundamentals of the ultrasound-driven physical and chemical events for delivering economically viable ultrasonics technology for industrial processes.

Key Research Areas

  • Synthesis of nanomaterials, microspheres, photocatalysts and polymers for catalytic and drug/flavour delivery applications
  • Ultrasonic processing of food and dairy ingredients for enhancing their functional properties
  • Degradation of organic pollutants in aqueous environment (wastewater treatment)
  • Single and multibubble sonoluminescence

Emulsion Behaviour

Emulsions and foams are important in the chemical, petroleum, coatings, food, electronics, pharmaceutical, cosmetics, and ceramics industries where an understanding of the nanoscale interactions and interfacial properties of these materials is crucial for improvements in formulation and processing.

Key Research Areas

  • Colloid and interface science relevant to the formation and stability of dispersions in aqueous and nonaqueous media
  • Surfactants – mechanisms, structure-property relations
  • Properties of emulsions and emulsifiers.
  • Quantification of particle size, charge, dispersion, stability, and rheological and electrokinetic properties
  • Stability of aqueous and nonaqueous dispersions

Surfactant & Polymer Structure in Solution

Complex fluids are common in everyday life and include foods, detergents and paints. The aim of this research program is to understand the relationship between the macroscopic rheological behaviour and the molecular forces and structure of the suspensions and polymer solutions.

Key Research Areas

  • Amyloid inhibitors
  • Biophysics of protein conformation
  • Condensed matter physics
  • Novel cancer therapies
  • Polymer dynamics in flow
  • Polymer rheology/rheofluorescence
