About the Project
This position is fully funded by the UCL-Diamond Collaborative Programme. The student will be registered for a PhD at UCL where he/she will spend initially for a period at UCL and substantial amount of time during PhD at Diamond Light Source. The Studentship will cover tuition fees at UK/EU rate plus a maintenance stipend.
Using principles of anomalous X-ray Diffraction and X-ray Absorption Spectroscopy, diffraction anomalous fine structure (DAFS) measurements have been developed as one of the SR techniques to measure site selective XAS. This technique has been demonstrated by measuring diffraction data of specific reflections as a function of the incident beam energy across an absorption edge, it is possible to extract XAS data pertaining to a specific crystallographic site. This method has been introduced and functioning in certain SR facilities, and we are aiming to implement and possibly improve the technique at DLS. The diffusion and practical application of DAFS is indeed limited to a few and well identified cases due to technical and analytical challenges. The PhD studentship will therefore focus on implementing novel approaches on both areas. A selection of advanced functional materials will be studied to gain a better understanding of the site specific structures correlated with functional properties.
The successful applicant should have or expect to achieve at least 2.1 honours or equivalent for undergraduate degree in Physics, Chemistry, Materials Chemistry. The successful applicant will demonstrate strong interest and self-motivation in the subject, good experimental practice and the ability to think analytically and creatively. Good computer skills, plus good presentation and writing skills in English, are required. Previous research experience in, general, synchrotron radiation techniques and specifically X-ray diffraction and/or X-ray absorption spectroscopic methods will be desirable, but not essential.
Interested candidates should initially contact Prof Sankar ([Email Address Removed] ) and Dr Giannantonio Cibin ([Email Address Removed]) with a degree transcript and a motivation letter expressing interest in this project. Informal inquiries are encouraged. Suitable candidates will be required to complete an electronic application form at http://www.ucl.ac.uk/prospective-students/graduate/apply and select Research degree:Chemistry programme. Any admissions queries should be directed to Dr Jadranka Butorac ([Email Address Removed]).
Applications will be accepted until 1 July 2020 but the position will be filled as soon as an appropriate candidate is found.
