Summary
Shape sorting of nanoparticles at oil-water interfaces in microchannels. This project aims to study the effect of shape on the adsorption of nanoparticles at an oil/water interface and develop a rapid, inexpensive, efficient, versatile method for shape sorting of nanoparticles using a microfluidic approach. This technique can be applied for fractionation of synthetic nanoparticles, biosample analysis and environmental monitoring.
Nanotribology and Nanorheometry: A Fundamental Study of the Dynamic Interactions of Particles and Surfaces at the Molecular Level. Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanom ....Nanotribology and Nanorheometry: A Fundamental Study of the Dynamic Interactions of Particles and Surfaces at the Molecular Level. Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.Read moreRead less
Development of a New Type of Large-Area Robust Superhydrophobic Surfaces (MWN). Electrochemical manipulation will be used to produce robust metal surfaces of controlled roughness and characteristic size of the surface features in the 10-1000 nanometre range. Subsequent surface modification (e.g. self-assembled monolayers, silane chemisorption, plasma polymer deposition) will render these surfaces superhydrophobic. The surfaces will have highly depressed adhesion properties and hence a significan ....Development of a New Type of Large-Area Robust Superhydrophobic Surfaces (MWN). Electrochemical manipulation will be used to produce robust metal surfaces of controlled roughness and characteristic size of the surface features in the 10-1000 nanometre range. Subsequent surface modification (e.g. self-assembled monolayers, silane chemisorption, plasma polymer deposition) will render these surfaces superhydrophobic. The surfaces will have highly depressed adhesion properties and hence a significantly improved chemical resistance and corrosion stability. A viable procedure for the making of polymer imprints from the metal surfaces will be developed. This will form the basis of a new method for cheap fabrication of various superhydrophobic surfaces with large areas and specific functionality.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.

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.

The emerging convergence of nanoscience and photonics offers the opportunity of using light to interrogate nanoscale domains, providing unprecedentedly localised measurements. This will allow biological scientists to understand how single cells react to and communicate with their surroundings. This science will underpin a new generation of devices capable of probing the response of cells within individuals to environmental conditions or treatment, creating innovative and powerful new sensing platforms.Read moreRead less
