Qualification Details

To qualify as a postdoctoral fellow, the applicant must have completed a Swedish doctoral degree or must have a foreign degree corresponding to a Swedish doctoral degree.

Preference will be given to candidates who have been awarded the degree no more than three years before the application deadline and who have not held a post-doc position within the same or similar subject area at the University of Gothenburg for more than one year. Applicants with a degree obtained earlier than the stipulated three years may be preferred if special reasons exists. Special reasons in this context include, but are not limited to, leave due to illness and parental leave.

In the selection of eligible applicants, the applicant shall be selected who, after an overall assessment of skill and development potential, is judged to be in the best position to carry out and develop the tasks described above. In the assessment, great importance will be given to documented scientific expertise and familiarity in the research area of the project. Publication in international journals is a merit, as are previous experiences of research and research collaborations in the field. In the selection process, interviews and reference taking can be considered. In the interviews, the applicants are given the opportunity to describe and develop their own views on the research area and their possible future role as a postdoc at the department.

Since the project is primarily based on using theoretical tools such as molecular dynamics (MD), Monte Carlo (MC) simulations and analytical theory, it is necessary to have knowledge and experience in these simulation methods. Knowledge of surface modeling and interfacial chemistry of nanoparticles in ionic solutions is merit giving.

The modelling work will be done in close collaboration with other groups in consortium which use experimental methods it is very important that candidate is at ease in collaborating with other groups as well as persons.

Responsibilities/Job Description

With support from Mistra, Department of Chemistry and Molecular Biology announces a postdoc position for two years with focus on investigating metal/metal oxide nanoparticles interaction with organic molecules in aqueous ionic solutions by using the multiscale simulations methods such as molecular dynamic (MD), Monte Carlo (MC) simulation methods and analytical theory.

Nanoparticles in natural aqueous systems such as lakes, rivers and sea water can be toxic for living organisms. However, the toxicity of nanoparticles is highly related with their state in which they exist i.e., as free particles, or in form of aggregates. Nanoparticles after entering into aqueous systems or in biological media can be transformed into complex aggregated state due to changes in their surface properties (surface charge, potential) in different environments or by the adsorption of organic matter. Changes in physical state can lead to changes in the reactivity of nanoparticles, therefore it is of utmost importance to understand the basic mechanisms underlie such changes. Transformations of nanoparticles in complex environments such as natural aqueous systems and in biological media are governed by the intricate relations of interaction forces acting on nano- as well as on meso-scales. To model the transformation in such complex systems, a multiscale modeling approach is needed. The project will be started with by modeling the surface charge and interfacial potential (zeta potential) of bare as well as coated nanoparticle in aqueous ionic solution and biological media. Corrected Debye-Hückel (CDH) theory, classical surface complexation and Molecular dynamics (MD) simulations will be used. Information gained from these investigations will further be used to model the formation of organic corona on the particle surface and aggregation in aqueous and biological media. Use of Monte Carlo (MC) simulations along with classical DLVO approach will be explored. The results of simulation will be compared with the relevant experimental data gained by other groups in a close collaboration.

This research project will be performed in a close collaboration between different groups in Mistra Environmental Nanosaftey consortium financed by Mistra. Groups from different disciplines such as physics, chemistry, biology, medicine and social sciences are collaborating in this consortium on the problem of Nanosafety.

About the Project and Electrochemistry group

Research project will be performed within Electrochemistry group. Research in electrochemistry group spans different areas. For example synthesis of metal oxide nanoparticles by electrochemical and solution based methods, studies of electrocatalytical reactions, experimental determination and modelling of the thermodynamical properties of electrolytes, investigations of particle size dependent surface and interfacial properties of nanoparticles by experimental and theoretical methods. Nanoparticles surface charge and potential at the particle solution interface play vital role in determining their reactivity, stability, aggregation and interaction with organic matter in complex electrolytes. In recent years focus has been on developing the experimental as well as theoretical methods to investigate in detail the nanoparticle solution interface. Electrochemistry group has well established international collaborations along with collaborations with other universities in Sweden and with industry.
