Doctoral Student in Physics: Developing time resolved APXPS for catalysis. (MSCA COFUND project PRISMAS) - Hiring in process/Finished, not possible to apply

PRISMAS - PhD Research and Innovation in Synchrotron Methods and Applications in Sweden – is a new doctoral network training the next generation of 40 leading synchrotron experts, and is co-funded by the Horizon Europe MSCA COFUND Programme.

As a PRISMAS PhD student, you will have the chance to conduct cutting-edge research in your field, taking advantage of state of the art tools that will lead to attractive future job opportunities in academia or industry. Moreover, you are part of designing the future of synchrotron technology and instrumentation and using these to tackle some of the most significant global challenges the world faces today while acquiring interdisciplinary and intersectoral knowledge. Being part of the PRISMAS programme gives you the one-of-a-kind experience in form of a secondment at the world´s first 4th generation synchrotron, MAX IV in Lund, Sweden. With a tailored training programme, including courses to build scientific and technical competence as well as strengthen transferrable skills, PRISMAS provides you with the skills, knowledge and competence needed to successfully achieve your doctoral degree.

Description of the workplace (“Your Team”)

The PhD position is placed at the Division of Synchrotron Radiation Research at the Department of Physics.

The Division of Synchrotron Radiation Research (www.sljus.lu.se) is a part of the Physics Department, with about 50 employees. The main focus of the research at the division is experimental studies of electronic, structural, and chemical properties of materials. At the division we use and develop a wide range of synchrotron- and lab-based techniques, including x-ray photoelectron spectroscopy central for this position.

The PhD student will also be part of the NanoLund (www.nano.lu.se), which is the Centre for Nanoscience at Lund University. NanoLund is today Sweden’s largest research environment for nanoscience, engaging approximately 270 PhD students and scientists in the Faculties of Engineering, Science, and Medicine. It operates Lund Nano Lab, a state-of-the-art cleanroom for the synthesis, processing, and characterization nanostructured surfaces.

At MAX IV the PhD student will work closely together with the APXPS team consisting of 11 scientists dedicated to keep our two APXPS beamlines HIPPIE and SPECIES operating 24/7 and to the continuous development of these beamlines.

Within the last 5 years the PI and co-workers at the division and in the APXPS team at MAX IV pioneered the field of time-resolved ambient pressure x-ray photoelectron spectroscopy. In particular, we developed in situ methodologies and instrumentation capable of measuring the chemical state of a catalyst surface and the localized gas composition above it– including product molecules formed - simultaneously and with ms to µs time-resolution. This gives unique possibilities study short-lived active phases and how the micro-equilibrium near the surface act as drivers of catalytic reactions. Currently, we are developing methodology and instrumentation for tr-APXPS further, a new endstation with unique possibilities for tr-APXPS experiments is being commissioned at the HIPPIE beamline and in the spring 2023 a new lab-based ambient pressure photo-electron spectroscopy instrument specially designed for time-resolved experiments will arrive.

What we offer

Lund University is a public authority which means that employees get particular benefits, generous annual leave and an advantageous occupational pension scheme. Read more on the University website about being a Lund University employee Benefits for employees | Lund University

The MSCA COFUND project PRISMAS offers you outstanding opportunities as well as a stimulating and inspiring surrounding for performing cutting-edge research. By supporting your mobility, it creates perfect conditions for strengthening your international network.

Work duties and responsibilities

The goal of this PhD project is twofold: (i) Develop photoelectron spectroscopy instrumentation and methodology for advanced time-resolved and event-averaged in situ measurements of catalyst surfaces exposed to cyclic gas composition or temperature pulses.  (ii) Use the new instrumentation and methodology to study structural oscillations on catalyst surfaces with high time-resolution and link this to catalyst function. Altogether, this gives a unique possibility to reveal short-lived species or phases on the catalyst surface impossible to detect in conventional APXPS experiments. For these studies we plan to focus on bimetallic transition metal surfaces and particles and study reactions ranging from CO oxidation to CO2 hydrogenation.

The methods and instrumentation developed in this project is expected to significantly improve the possibilities at the APXPS beamlines at MAX IV and can easily be transferred to scientific areas beyond catalysis and techniques beyond APXPS.

The PhD student is expected to work independently as well as in close collaboration with other researchers associated with the project. In particular, the student will work closely together with one other PhD studying carbon hydride oxidation with tr-APXPS and one other PRISMAS student studying atomic layer deposition with tr-APXPS. The successful candidate will also be given an opportunity to assist in the supervision of master students. Within the position there will be plenty of possibilities for collaboration on rich variety of projects performed at the MAX IV beamlines and at our division.

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties can also include teaching and other departmental duties (no more than 20%).

Supervisors for this project will be: Jan Knudsen (main supervisor), Andrey Shavorskiy (co-supervisor, MAX IV), Joachim Schnadt (co-supervisor)

The training implies a secondment of 3-12 months at MAX IV laboratory in Lund, Sweden. Additional secondments and/or short stays may be arranged in agreement with the supervisor of the research project. Moreover, you will attend international conferences, participate in periodical project meetings and training schools as well as in specialised courses at different universities to complement your knowledge.  A certain amount of travelling is foreseen in relation to these activities.

Qualifications

Selection to postgraduate studies is based on the expected ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of studies at the basic and advanced levels, in particular:

• You have knowledge and skills relevant for the thesis project.
• You have good written and oral communication skills.
• You have the ability to work independently and to formulate and tackle research problems.
• Other experience relevant to postgraduate studies, such as professional experience.

It is an additional qualification if you have experience of

• programming.
• working ultra-high vacuum equipment.
• working synchrotron facilities
