Closing the data gap: High throughput screening of nanoparticle toxicity. The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety.

The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety. This project aims to develop new methodological and conceptual avenues to close the gap between innovation in nanotechnology and risk assessment. This is intended to be achieved by developing and validating high-throughput in vitro toxicity screening platforms for manufactured nanoparticles. The approach is based on advanced lab-on-a-chip microfluidic technologies. The predictive power of the platform will be refined and optimised via ex-vivo and in-vivo models.Read moreRead less
Patchy colloidosomes at interfaces: correlation of particle surface heterogeneity, wettability, and chemical activity at the nanoscale. The surfaces of natural mineral particles are made up of spots with such different chemical and physical properties. The complexity makes it hard to predict their behaviour. This project will provide insights into how the 'patchy' nature of particle surfaces affects their behaviour in processes such as flotation separation and bio-fuel production.

Advanced Macromolecular Materials Characterisation Facility (AMMCF). Advanced macromolecular materials characterisation facility: The facility will allow precise characterisation of (bio)macromolecular materials, from chemical structures and composition as a function of size or biodistribution, to film thickness in multi-layer materials, to material hydrophobicity and permeability. Novel information derived from these state-of-the-art instruments is highly valuable in understanding structure-pro ....Advanced Macromolecular Materials Characterisation Facility (AMMCF). Advanced macromolecular materials characterisation facility: The facility will allow precise characterisation of (bio)macromolecular materials, from chemical structures and composition as a function of size or biodistribution, to film thickness in multi-layer materials, to material hydrophobicity and permeability. Novel information derived from these state-of-the-art instruments is highly valuable in understanding structure-property relationships, which are crucial for the development of the next generation of advanced materials with applications in electronics, optics, sensors, membranes, nanocoatings, biomaterials and polymer therapeutics. This facility underpins the efforts of the participating institutes in increasing the quality and quantity of research outcomes.Read moreRead less

Novel nanosensors for monitoring of water filtration membrane integrity. This project aims to develop arrays of electrochemical biosensors based on nanostructured silicon for real-time monitoring of water filtration membrane integrity. Real-time monitoring of membrane performance, based on removing virus-sized particles, is a priority for the water industry to maximise asset life and meet increased demand for safe and high-quality water. Materials scientists, electrochemists, and specialists in water management and reuse aim to harness advances in nanostructured transducers and electrochemical protocols to develop online performance-monitoring technology. This project is expected to improve water treatment processes, removing viruses and reducing the risks and uncertainties of water recycling.Read moreRead less
Engineering the sulphidising reactions for flotation of low quality ores. Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting.

Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting. However, the current sulphidisation method is neither efficient nor widely used. This project will tailor sulphidisation reactions to generate desirable surface products that are not sensitive to flotation conditions. The intended outcome of this project is to provide a step change value in processing low quality resources while minimising the environmental effects of stockpiles.Read moreRead less
Reducing the deleterious impacts of clay particle interactions with valuable minerals in copper and gold processing. This project seeks to understand the rheological behaviour of clay minerals and the effect of the viscosity caused by clay minerals on gas dispersion, the transport of network structures and the locking of the structures in the froth in mineral flotation. Novel methods will be developed to improve flotation separation by reducing the viscosity.
Regrinding chemistry and particle breakage mechanisms in increased surface hydrophobicity on fine and ultra-fine particles in mineral flotation. This project will study the effect of regrinding chemistry and particle breakage mechanisms on the redistribution of flotation collectors and the evolution of the metal oxidation species on mineral surfaces. New technologies will be developed to increase mineral surface hydrophobicity and therefore increase fine and ultra-fine particle flotation.
