Profile
Dr Darrell Alec Patterson is a Senior Lecturer (Associate Professor) in Chemical Engineering and leads the Nanostructured and Tuneable Materials laboratory at Bath. He is also a member of the Centre for Sustainable Chemical Technologies and the Bath Membrane Science and Engineering Research Cluster, Membrances@Bath. He is Chair of the Department of Chemical Engineering Research Committee.
Darrell's research is in three main areas, all aiming to characterise and produce sustainable chemical technologies:
- Membrane Science and Engineering
- Wastewater Treatment Technologies
- Catalytic Reaction and Reactor Engineering.
Darrell completed his Bachelor of Engineering with First Class Honours (UK first class MEng equivalent) in Chemical and Materials Engineering at the University of Auckland and his PhD in Chemical and Biochemical at Imperial College in 2001.
He worked as a Technology Development Consultant for Atkins Water between 2001 until 2003. He then went on to Imperial College as a postdoctoral research associate developing novel methods of enhancing solvent based pharmaceutical reactions through integration with solvent resistant membranes.
He returned to the University of Auckland in 2005 where he worked as a Lecturer and then Senior Lecturer in the Department of Chemical and Materials Engineering before joining the University of Bath in 2011.
Research
Darrell's research is in the area of Sustainable Chemical Technologies focusing on Separation and Reaction Engineering. The focus is on the synthesis, fundamental characterisation and application of nanostructured and tuneable materials in environmental and sustainable applications in three main areas above. Expertise and projects include:
1. Membrane Science and Engineering
- Tuneable membranes and membrane reactors (primarily focused on applications of conducting polymers as the next generation of membrane materials)
- Polymer nanofiltration and mixed matrix membranes for currently unachievable and unconventional separations (e.g. in organic solvent and acidic or basic environments; protein isolation; wine fining)
- Membrane fractionation cascades for product synthesis and isolation (focussing on pharmaceutical and nutraceutical compounds from plants)
- Wet and in-use imaging of membranes using DIC microscopy, nanoindentation and ESEM.
2. Wastewater treatment technologies:
- Photocatalysis: nanostructured thin film ZnO and TiO2 photocatalysts
- Photocatalytic process intensification: Spinning disc and mesh photoreactors for enhanced reaction rate
- Treatment of wastewaters with pharmaceutical and endocrine disrupting pollutants
- Recycle and reuse of wastes into value-added products: sea shell waste conversion into value-added biomedical, catalytic and adsorbent materials.
3. Catalytic Reaction and Reactor Engineering
- Nanostructured catalyst synthesis, characterisation and application
- Thin film catalytic reaction and reactor engineering
- Immobilized enzyme reaction and reactor systems
- Process intensification: spinning disc and spinning mesh reactors for thin film and enzyme reaction enhancement; membrane reactors.
