Product Name: Division of Structural Chemistry

Product Description

The division of structural chemistry is part of the Department of Physical, Inorganic and Structural Chemistry at Stockholm University.

The division hosts about 40 people including 13 PhD students.

Research

The physical, chemical and mechanical properties of a material are a function of both its thermodynamic parameters (composition, temperature and pressure) and its atomic arrangement: its structure. Once we have the crystal structure of a material then it is in most cases possible to calculate its bulk properties. Structural information can be obtained directly by X-ray and neutron crystallography and by electron microscopy. Data on atomic structure may also be gathered through spectroscopy, especially methods that are sensitive to local structure such as Raman, IR and NMR. At the Division of Structural Chemistry at Stockholm University we have a long tradition of developing crystallographic methods for studying crystal structures using X-ray, neutron and electron diffraction/imaging. Modulated and quasi-crystalline materials and structural transformations with pressure and temperature have also been studied.

The aim of our research is to determine the arrangement of atoms, especially in demanding cases, such as very small particles, often under extremely demanding physical conditions, such as high temperature and pressure. Materials of interest include porous materials quasicrystals and modulated structures. Structure studies of these materials are challenging and we are developing new crystallographic and spectroscopic methods. The research at the division of Structural chemistry is at the frontier of this research, especially regarding electron microscopy and electron crystallography. Our EM facility is very new and well equipped.

Project overview

The Division of Structural Chemistry at the Department of Physical, Inorganic and Structural chemistry is host for a number of research groups and projects.

There is a strong tradition of using and developing diffraction techniques for structural determination. Following this tradition, the two groups of Prof. Osamu Terasaki / Dr. Yasuhiro Sakamoto and Prof. Sven Hovmöller / Prof. Xiaodong Zou are independently working on the development of crystallographic methodology.

However, the main part of the research of our department concerns the synthesis and characterisation of new materials. Here, nano-sized materials and porous materials are of special interest. Many of them have very promising catalytic properties while others can be used in controlled drug delivery.

There are also research groups working in energy related projects such as the search for and improvement of metal-hydrides for use in batteries, run by Prof. Dag Noreus. Another energy related project concerns the synthesis and characterisation of perovskite related cobalt oxides for electrode materials in fuel cells, lead by Prof. Gunnar Svensson.

Although most of the research is focussed around the use of diffraction as the characterisation technique there are also projects using spectroscopic methods like Raman, IR and EXAFS for structural characterisation, like the project concerning metal complexes lead by Prof. Magnus Sandström. He is also the leader for a project how to prevent the historical Vasa shipwreck from deteriorating from sulphuric acid formed by oxidation of sulphides present in the oak wood (VASA).

The long experience in using diffraction techniques for structure determinations has given the department a strong competence in this field and a strong network of collaborators. Structural chemistry is also host to a group working with protein structure description and predciction, lead by Prof. Sven Hovmöller.

Company Details

The department today hosts about 95 people, and we are one of the oldest chemistry departments at Stockholm University. The chemistry section, including the department, moved from Kungsstensgatan 45 to our current location in the Arrhenius... more
