PhD student in Materials Chemistry (A)

at the Department of Materials and Environmental Chemistry. (Closing date: 5 November 2018.) Prolonged application time- new closing date: 11 January 2019.

The Department of Materials and Environmental Chemistry (MMK) is one of the largest departments at the Faculty of Natural sciences with about 130 employees. The research activities of MMK are in the areas of Materials and Solid-state Chemistry focusing on different classes of materials; e.g. ceramics and glasses, self-assembled and porous materials, and soft matter. The work often encompasses synthesis, characterisation by X-ray diffraction and electron microscopy, NMR studies, modelling with computer simulations of materials with a potential for various applications. Environmental aspects are an important part of the research activities.

Project description 
Project title: From poly(ionic liquid) to porous Heteroatoms-doped Gradient Carbon Membrane (MMkol membrane project).

Supervisor: Associate Prof. Jiayin Yuan, jiayin.yuan@mmk.su.se.

Membrane fabrication and application is a mature technology widely used in both industry and in our daily life. Nanoporous carbon membranes are membranes made up from carbon materials with interconnected nanopores (1 - 100 nm in size) densely packed inside. They are very useful in tackling challenges in the energy and environmental fields.

This project aims at developing nanoporous carbon membranes in large size and scale, which bear desirable structural features for their high-end applications. These membranes are named porous heteroatoms-doped gradient carbon membrane, in short MMKol membrane. MMKol membranes carry pore size of different types, including micropores (< 2nm), mesopores (2-50 nm) and large macropores (> 50nm). This pore size combination helps MMKol-membranes realize their function with high rate and capacity. Another unique feature of such membranes is the heteroatom-doping effect. Heteroatoms, such as nitrogen, sulfur and boron are known to improve the physical properties of carbon materials, thus offers a convenient tool to tailor their properties. Last but not the least, the membranes possess a structural gradient across the membranes. The design of structure gradients introduces a smooth variation of structures from one type to the other without creating unstable interfaces, thus extending the life of multicomponent systems.

The aforementioned unique structure design makes MMKol membranes standing out of its class. They can find useful applications in the energy field, such as ionic diode carbon membranes that can harvest salinity gradient power, so called “blue energy” from sea water and river water. Alternatively, they are to be used as high-performance electrode in electrochemical energy devices. Because of the structural integrity, the MMKol membranes can avoid polymer binders, which must be adopted for powderous carbons for electrode processing and causes stability problems. Besides these two examples, more application possibilities are expected from this new generation of porous membranes.

Qualification requirements
In order to meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

In order to meet the specific entry requirements, the general syllabus for doctoral studies in the field of Materials chemistry is valid. Those studies should include at least one specialized course or a thesis in the research subject. In order to facilitate the evaluation of merits and suitability for the PhD studies your curriculum vitae (CV) should contain information about the extent and focus of the academic studies. The quantity (as part of an academic year) and the quality mark of courses in chemistry and physics are of particular interest. Please, state titles of undergraduate theses and project works. The primary assessment criteria in appointing a doctoral student should be the capacity to benefit from the training.

The qualification requirements must be met by the deadline for applications.

Selection
The selection among the eligible candidates will be based on their capacity to benefit from the training. A committee will go through the applications and rank after the applicants capacity to benefit from a PhD education. The following criteria will be used to assess this capacity: the candidates’ documented knowledge in a relevant field of research, written and oral proficiency in English, the capacity for analytical thinking, the ability to collaborate, as well as creativity, initiative, and independence. The assessment will be based on previous experience and grades, the quality of the degree project, references, relevant experience, interviews, and the candidate’s written motivation for seeking the position. A short list will be set up and interviews with the top candidates will be carried out at the department or via internet.

Economic support for the PhD studies are guaranteed for full time studies during the time period agreed on in the individual study plan. The studies does normally mean four years full time studies. You are encouraged to contact the project leader for more information about the project. For general information about the Department of Materials and Environmental Chemistry please contact the Head of the Department, Professor Gunnar Svensson, gunnar.svensson@mmk.su.se.

Admission Regulations for Doctoral Studies at Stockholm University are available at: www.su.se/rules.

Terms of employment 
Only a person who will be or has already been admitted to a third-cycle program may be appointed to a doctoral studentship. Starting in May 2019 is preferred, but can be negotiated.

The term of the initial contract may not exceed one year. The employment may be extended for a maximum of two years at a time. However, the total period of employment may not exceed the equivalent of four years of full-time study.

Doctoral students should primarily devote themselves to their own education, but may engage in teaching, research, and administration corresponding to a maximum of 20 % of a full-time position.

Please note that admission decisions cannot be appealed.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
