research interests
My current research interests focus on the particulate materials and their surfaces including their role in product manufacture for both biological and non-biological materials. I have developed a number of new experimental methods for determining a range of surface and bulk physicochemical properties of powders and particulate materials including mechanical, topographical, chromatographic and surface properties.
Current studies have included studies of protein aggregation, freeze drying, peptide formulations, peptide chromatographic purification, adsorbents for CO2, SO2, VOC and organic pollutant capture, novel engineered sponges, caking and powder flow for complex powders, antimicrobial polymer surfaces, surfactant coated polymers and reactant diffusion in catalyst particles . The group has world leading expertise in gravimetric characterisation methods as well as inverse chromatographic methods, having pioneered many of these approaches. For example, the water sorption characterisation of many classes of materials, especially pharmaceuticals, bio-mataterials and biopharmaceutical is an area of significant interest. Current and new project areas include:
- Adsorption and new adsorbents for CO2 and SO2 capture
- Effect of water vapour on adsorbent performance
- Surface energy and powder flow for pharmacetuical powders
- Surface properties of Complex Polymer Substrates
- Micromechanics of agglomerates and cellular entities
- Stability and performance of MaB bioformulations
- Second virial coefficients and peptide-peptide aggregation behaviour
- Fundamentals of RPLC chromatographic separation of peptide
- Stability and the freeze drying of therapeutics
- Nano-engineered sponges for microbe and oil pollutant capture
- Miniature instrumentation for process monitoring
- Diffusion of liquid phase reactants in porous catalyst particles
- Surfaces and Particle Engineering Laboratory
- SMS - UK Surface Measurement Systems
