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.

Summary
Study of oriented attachment of nanocrystals at oil-water interfaces. This project will study the fundamental issues for crystal growth, which will dramatically facilitate the development of effective pathways for the synthesis of advanced nanomaterials for nanodevice and nanotechnology. The obtained outcomes will enhance our knowledge in crystal growth and colloid sciences.
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
Nanoparticle adsorption at air-water interfaces for foam stabilization. Pharmaceutical formulations and lightweight materials and processes such as mineral flotation and biocatalysis depend on the interactions between air bubbles and particles in water. This project will provide in-depth insight into how the physics and chemistry of the particle surfaces control the structure of the materials formed in those processes.
Novel Tunable Nanostructured Electrodes. This project aims to build novel, highly efficient electrodes using a nanostructured layer approach. The layers are proposed to be made of chirally-selected carbon nanotubes, conducting polymers and charge carrier blocking layers and provide tunable energy pathways for electrons and holes. The project aims to probe these pathways to understand carrier lifetimes and how charge is transported from one layer to the next, ultimately leading to an ability tune ....Novel Tunable Nanostructured Electrodes. This project aims to build novel, highly efficient electrodes using a nanostructured layer approach. The layers are proposed to be made of chirally-selected carbon nanotubes, conducting polymers and charge carrier blocking layers and provide tunable energy pathways for electrons and holes. The project aims to probe these pathways to understand carrier lifetimes and how charge is transported from one layer to the next, ultimately leading to an ability tune electrodes such that matched 'downhill' energetic pathways exist leading to unprecedented charge carrying capability. The electrode properties can be tuned with the selection of the layer materials and is expected to find applications in fields ranging from photovoltaics to sensors to electronics.Read moreRead less
