About Us
Diamond Light Source is the UK’s national synchrotron science facility. By accelerating electrons to near light-speed, Diamond generates brilliant beams of light from infra-red to X-rays which are used for academic and industry research and development across a range of scientific disciplines including structural biology, physics, chemistry, materials science, engineering, earth and environmental sciences.
The Project
A funded PhD studentship is available as a joint position within the groups of Dr Alex Saywell (University of Nottingham - Nanoscience group) and Dr David Duncan (Diamond Light Source – Structures and Surfaces). The studentship will be hosted at the School of Physics and Astronomy (Nottingham), where you will have access to a range of experimental techniques, including low-temperature ultra-high vacuum scanning probe microscopy (SPM) and X-ray photoelectron spectroscopies. You will also be part of the vibrant research community in the Physical Sciences division of Diamond Light Source (Oxfordshire), where you will have access to experts in a wide array of experimental methods, including X-ray photoelectron spectroscopies and transmission electron microscopies. An enhanced stipend, above the UKRI minimum, is awarded with this studentship.
Project overview: Catalysts are involved in the manufacture of almost every consumer product, from food to telephones. Major advances in catalysts make everyday products cheaper, reduce industrial waste and pollution, and make industrial processes more energy efficient. Thus, improvements in catalysis are key to transitioning the world economy to a sustainable state.
Single atom catalysis, where single metal atoms are dispersed across a supporting material, has become a popular field over the last decade. Single atom catalysts (SAC) offer a route to catalysts that have the high selectivities of homogenous catalysts, but the ease of catalytic recovery from heterogenous catalysts. The key to generating a SAC is preventing sintering of the single atoms into nanoparticles by the utilisation of specific supporting substrates. Defective-graphene is one such substrate, and we have recently developed a methodology to prepare defective-graphene films from the bottom up using topological design.
In this studentship we will further develop this field of by studying the interaction of topologically designed defective-graphene substrates with metal atoms. This will be done through a rigorous scientific programme both at Diamond Light Source and at the University of Nottingham. The student will exploit cutting-edge scanning probe microscopy and lab-based ambient pressure X-ray photoelectron spectroscopy measurements at the University of Nottingham to fully characterise how these metal atoms disperse on the substrates and how these dispersed metal atoms interact with gases of interest. At Diamond, the student will exploit the unique-in-world capabilities at I09 to quantitatively determine the adsorption structure of the coordinated metal atoms. The work is done in collaboration with other Universities in the UK, Europe and the USA, as such the student will gain experience in working within an international collaborative environment.
Details of funding: Funding for this position is open to UK applications, and the 4-year studentship will commence in October 2023 (earlier start dates may be available upon request). The stipend is set at £2000 per year above the UKRI minimum. A degree in a relevant physical sciences discipline is required.
Further nforformation
Diamond Light Source Ltd holds an Athena SWAN Bronze Award, demonstrating their commitment to provide equal opportunities and to advance the representation of women in STEM/M subjects: science, technology, engineering, mathematics and medicine.
Diamond jointly funds around 15-20 studentships every year with a variety of collaborators from both academic institutions to industry partners. Students accepted onto these projects will be part of our yearly cohort intake and are supported by both their academic and Diamond supervisors, as well as a dedicated Student Engagement team based at Diamond.
Diamond studentships are typically 50% funded by Diamond and 50% by the partnering university institution (or 25% funded by Diamond if there is a third party collaborator). Students are therefore required to spend 50% of their studentship at Diamond, with most students relocating to the local area for this period. Support on suggested accomodation options are provided by Diamond.
