Current PhD Projects

Once completing the MRes component of the course, the students then continue on to their three-year PhD. Below you'll find details of each individuals project which many have extensive support from industrial partners.

The EPSRC Centre for Innovative Manufacturing in Ultra Precision also has a number of PhD students doing their studies in this area of manufacturing. Further details of these can be found here.


 

Ultrafast machining of high temperature superconductor nanostructures for novel mesoscale physics

High temperature superconductors (HTS) are novel materials that exhibit zero electrical resistance and exclusion of magnetic fields at temperatures over 77 K. The main aim of this project is to enhance the critical current density (Jc) of thin-film HTS bridges by creating edge-barrier pinning. Assuming a perfect edge, edge-barrier pinning effects bridges as large as 200 μm. This limit becomes smaller as edge quality degrades. Unlike photolithography, laser machining is a chemical free, flexible process; the use of an ultrafast laser gives minimal edge damage.

Ultrafast terahertz spectroscopy of highly aligned carbon nanotube textiles

The project is concerned with bringing new insights with regard to the fundamental electrical properties of the carbon nanotube (CNT) textiles being produced by the University of Cambridge's Macromolecular Material Laboratory (MML). Utilising time-domain spectroscopy (TDS) and optical pump-terahertz probe spectroscopy (OPTPS) charge-carrier lifetimes, insights into the charge-carrier dynamics and quantities equivalent to ac conductivity can be extracted. It is hoped that through examination of the results from OPTPS, a characteristic ratio of the semiconducting-to-metallic nanotubes present in each textile can be found.

XCT calibration via softgauges

X-ray computed tomography (XCT) has been used widely as a non-destructive testing tool in the quality of additive manufactured components. However, the software developed for XCT are mostly used for visualisation purposes, where there is limited understanding of the traceability and uncertainty of the software. This project will develop and validate an XCT soft-gauge framework that will contribute to future XCT calibration process. This proposal follows up a previous short term MRes project that looked into the development of simulation data for software gauge purposes.

Continuing my long project ensured I was ready to hit the ground running when I transitioned from MRes to PhD.
