[OPEN POSITION]: PhD student in Neutron scattering - Probing multiple length scales in functional nanomaterials

PhD student in Materials Chemistry (B) - Ref. No. SU FV-3278-18


at the Department of Materials and Environmental ChemistryClosing date: 5 November 2018.
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: Neutron scattering as a multiple length scale probe for functional nanomaterials.
Supervisor: Associate Prof. German Salazar Alvarez, german.salazar.alvarez@mmk.su.se.
The project will focus on studying different types of nanomaterials with neutron scattering at the atomic (diffraction) and nanoscopic (small angle neutron scattering, SANS) levels. The work implies comprehensive experiments with neutron scattering in neutron facilities around the world with focus on the multiple length scale approach. The work also includes development, and testing of different sample environments for in-situ characterisation of nanomaterials.
The project is a collaboration between Stockholm University (SU), Uppsala University (UU), and the European Spallation Source (ESS) and has as a long-term plan to expand the neutron diffractometer DREAM at the ESS in Lund to study nanomaterials. Within the project, we will design different sample environments to enable the simultaneous acquisition of data in two length scales (atomic and nanoscopic). In this way, the connection between the variations in the crystal structure and nanoparticle morphology can be established. This will be used to study three different materials classes that have a strong research tradition in Sweden: biomaterials, batteries, and magnetic materials. Some examples of the possible studies include self-assembly of small cellulose fibres, how the structure of batteries changes during usage, or how magnetic nanoparticles assemble under an applied magnetic field. The project is financed by the Swedish Research Council.
The successful candidate should have a background in chemistry or materials science with an interest in utilizing characterization methods such diffraction with Rietveld analysis and/or small-angle scattering. Experience in PDF-analysis of nanomaterials is advantageous. Knowledge of TEM is meritorious but not a requirement.

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 programme may be appointed to a doctoral studentship.
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.

[OPEN POSITION]: PhD student in Inorganic Chemistry

PhD student in Inorganic Chemistry

Project descriptionProject title: Synthesis and characterization of nanoparticles for electrocatalytic production of hydrogen.
Supervisor: Professor Mats Johnsson, mats.johnsson@mmk.su.se.
The project will focus on synthesis and characterization of nanoparticles aimed as electrocatalysts for hydrogen production based on excess glycerol from biofuel production and waste carbohydrates from wood-based Kraft pulp processes.
Many research projects aiming at hydrogen production focus on water splitting. The water oxidation reaction is associated with high anodic potentials due to unfavorable thermodynamics and slow reaction kinetics. Oxygen is a by-product from hydrogen production from water and is normally just released into the atmosphere. The approach in the present project is to replace the anodic reaction with partial oxidation of alcohols that results in a large decrease in electrical energy demand for hydrogen evolution and also valuable anodic products. This PhD project is part of the program Materials for energy applications funded by the foundation for strategic research (SSF). The project group consists of researchers from KTH and SU and the PhD student will also interact with Swedish enterprises. The target of the program is development of efficient and selective catalysts through an effort involving theory, materials and electrocatalytic design and testing.
The successful candidate should have a background in chemistry or materials science with an interest in synthetic inorganic chemistry and in utilizing several characterization methods such as SEM-EDS, TEM, Powder X-ray diffraction, and electrochemical measurements. Knowledge of those methods is a plus although not strictly required.
