Experimental and Computational Micro-Characterization Techniques in Wood Mechanics

Research Institute


Description

The University of Helsinki is the largest university in Finland with 38,000 degree students and 7,600 staff. The University of Helsinki is a member of the League of European Research Universities. The Faculty of Science of the University of Helsinki undertakes research and teaching in the exact sciences, as well as in the applied fields of geography and geology. Faculty of Science has about 6,000 students pursuing their first degree and some 700 postgraduate students.

Department of Physics has a staff of about 210 employees and 28 professors and performs research in physics, meteorology and geophysics. Soft condensed matter physics, and biophysics are among the main areas of research within the Division of Materials Physics. Fundamental understanding of the X-ray based characterization techniques is utilized to explain the various macroscopic properties of novel materials. In addition to the versatile X-ray instrumentation in the laboratory, synchrotron radiation based experiments play a vital role in the research activities of the division.

Infrastructure

The Department of Physics has several modern x-ray scattering setups at its disposal. These setups include two small-angle x-ray scattering setups: one based in a conventional x-ray tube suitable e.g. for studies of particles in solutions and the other based on a rotating anode x-ray tube suitable for time-resolved studies. Both these setups include a two-dimensional detector and are appropriate for characterization of samples with preferred orientation of structural units. Conventional powder diffractometers are available for characterization of structures of both amorphous and polycrystalline materials. For structural studies at the micrometer level a new x-ray microtomography setup is available. For studies on the mechanical properties the division of materials physics has a mechanical testing device and ultrasonic setups.
