Experimental and Computational Micro-Characterization Techniques in Wood Mechanics

Research Institute


Description

Metla's mission is to promote, through research, the ecologically, economically and socially sustainable development of the forests and forestry. Metla conducts research and generates research information about the forest nature and environment, the different uses of forests, and about forestry and the forest cluster.

Research is organised into problem-oriented projects and multi-disciplinary research programs. Metla also carries out commissioned projects to meet the information requirements of its customers. In recent years, the overall budget of the Finnish Forest Research Institute has been about 40 million €.

My research team at Metla uses the facilities of The Wood Laboratory at the Vantaa Research Unit, which is equipped with polarizing and fluorescence microscopes and image analysis system (Image-Pro software with colour digital video cameras) and laser diffraction equipment to study wood structure. Standard methods are used to determine growth ring width, earlywood-latewood ratio, moisture content, basic density and strength of wood. Modern analytical instruments are available in Vantaa Research Unit to study wood components (TLC, GC, HPLC, GLC-MS, NIR/FTIR).

Collaboration have been done with the group of Prof. Ritva Serimaa at the Helsinki University Department of Physcis, which has available modern rotation anode and sealed x-ray tube based wide and small angle x-ray scattering setups (WAXS, SAXS) at Division of x-ray physics and ultrasonic testing with Electronics lab. Research using synchrotron radiation has been carried out in Hasylab, Hamburg, and ESRF, Grenoble. Collaboration is also going on with Helsinki University of Technology to use confocal Raman microscopy.
