Project description
Explosives and their precursors are a serious threat for defence and security in both military and civilian contexts: trace vapour detection of explosive compounds or precursors is still beyond the reach of current Explosive Trace Detectors (ETDs). These often rely on mechanical sampling (‘swabbing’) with subsequent desorption and analysis, which is impractical in many settings and impossible with any concealed or wrapped explosive inaccessible to sampling. These limitations affect the currently available ETD-ready technologies: lack of sufficient sensitivity, incompatibility with use outside of laboratory settings, easily evaded operational requirements or a combination of these limitations make real-time vapour trace detection of explosives a much wanted unmet capability.
Surface-enhanced Raman spectroscopy (SERS) is a laser based technique that provides ultra-sensitive molecular ‘finger-printing’ capability in which the University of Southampton has a world-leading track-record (https://www.southampton.ac.uk/chemistry/about/staff/sm13g12.page?msclkid=72596b9ab32711eca8e3769eebddb186#publications). In this project a novel SERS based approach for the sensitive direct detection and identification of explosive trace vapours will be developed. The sensitivity of SERS will be combined with innovative concepts in data analysis and device development that will lead to a laboratory prototype. This project will be a step towards realisation of a novel class of explosive trace detectors fulfilling a vital need in defence and security and beyond.
In this fully-funded interdisciplinary PhD opportunity the student will learn and develop advanced spectroscopy techniques, analysis methods as well as rapid prototyping approaches (e.g. 3D printers and laser cutters) for device development. The student will have the opportunity to work with scientists and engineers at Smiths Detection to develop potential designs for field conditions. Training in all areas of the PhD as well as opportunities for professional development will be available but enthusiasm to work in a dynamic and interdisciplinary collaborative environment is desirable.
If you wish to discuss any details of the project informally, please contact Prof. Sumeet Mahajan, Email: [Email Address Removed].
Entry Requirements
An undergraduate degree (at least a UK 2:1 honours degree or equivalent) in Chemistry or Engineering or allied subjects/relevant disciplines. Enthusiasm to work in an interdisciplinary environment with a hands-on attitude and strong interest or background in either analytical spectroscopy, data analysis and/or device development/prototyping is highly desirable. Training in all areas of the PhD and professional development opportunities will be provided.
Closing date: As soon as a suitable candidate is found but no later than 30th April for standard entry in Sept 2023. The first round of interviews are likely to be in 1st/2nd week of Feb 2023.
Funding: The project is fully funded for 3.5 years for UK students and full tuition and an enhanced stipend of £17,668 tax-free per annum will be provided.
