Base isolation is of great importance for the safety of infrastructure, such as hospitals, bridges and nuclear power plants. Utilisation of a traditional passive base isolator makes the base isolation system vulnerable and susceptible to unexpected/extreme dynamic loadings, such as earthquakes. This project aims to address this critical issue through the development of a novel adaptive seismic isolator working with an innovative stiffness softening magnetorheological elastomer (MRE). This research represents a fundamental step towards the understanding of MRE behaviour and is expected to be the breakthrough for the development of a future smart base isolation system.Read moreRead less
The photons take charge: Elucidating the structure and stability of distonic radical anions by mass spectrometry and photoelectron spectroscopy. Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability.

Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project will probe the fundamental structure and energetics of radical anions by modifying instrumentation to enable multi-step gas-phase ion synthesis to be efficiently coupled with anion photoelectron spectroscopy. These investigations are essential to revealing the scope of this phenomenon in free radical chemistry and biology and could inform future development of new catalysts for polymerisation.Read moreRead less

Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less
Integrity prediction of ground precision surfaces. This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions.

This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions. To date, the surface integrity of a ground component cannot be predicted due to the involvement of many random factors and variables in a precision surface grinding process, resulting in high failure rates and processes requiring repeated surface measurements. The novel approach for surface integrity prediction developed by this project will make a vital step forward in advancing the discipline of precision surfacing, establish a new knowledge base and bring about significant technological impacts to the manufacturing industry.Read moreRead less

By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less

The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range. Using this technology, the project plans to initially design and test a single optrode device on the bench, before in vitro testing and characterisation using two-photon microscopy. The final design would be a higher density sensor array using a fibre optic source and multiple optical couplers. This may support the development of new ways to implant sensing and diagnostic devices in the body.Read moreRead less
