Novel Technologies

Technologies include development of novel tools to monitor marine food safety, water detection and Remediation and the use of biomenbranes in wastewater treatment. 

Professor John Cassidy. Characterisation of emerging pollutants and detection of trace persistent organic pollutants and heavy metals in water.

Complexing agents within sensors respond to changes in chemistry surrounding it and elicit an electrochemical or colorimetric response that can be measured. Anodic stripping voltammetry (portable detection method) was used to determine very low levels of lead (i.e. 25 parts per billion) in water. Other work investigated water remediation through accelerated oxidation methods and photo-electrochemical techniques. This has the dual benefits of cleaning the water while also generating small amounts of electricity. 

 

Professor John Cassidy. Compost in Crop Production: Predicting Nutrient Release from Composted Waste Materials.

 

Dr Patrice Behan. Analytical Method Development using modern analytical instrumentation for a range of food residues and environmental pollutants.

Researchers are developing passive samplers to measure time integrated trace levels of organic pollutants in marine and freshwater environments. Other work investigates the impact of septic tanks on surface waters and wells for drinking water supply. This includes optimising a GC-MS method for the analysis of sterols from humans and animals to identify the source of faecal pollution in receiving waters. 

 

Dr Ben Shazmann. Chemical modification of polyvinylchloride (PVC) to create new materials.

Work includes developing novel analytical tools and applications targeting a variety of ionic analytes in water (e.g. Fluoride, Iodide, Nitrate); such technologies are reliable miniaturised alternatives to existing sensors.  

 

Dr John Colleran. Development and characterization of composite materials for novel biological, inorganic and environmental applications.

Development of composite modified electrodes for applications in electrochemical sensing and bio-sensing, energy, & environmental technologies; Elucidation of mechanism and kinetics of redox reactions at modified electrodes; electrochemical characterisation of organometallic compounds.
