Scanning Transmission X-ray Microscopy as a tool for examining chemical changes in wood cell walls due to enzymatic activity
2014 - IRG/WP 14-20556
As development of techniques for examining enzymatic activity on solid, complex biological materials, is considered to be an important factor in further development of enzyme applications and for understanding the decay of plant materials, this study explores applicability of Scanning Transmission X-ray Microscope (STXM) for determining chemical changes in enzymatically treated samples at the cell...

Development of a new characterization method to analyse Cypermethrin penetration in wood material by immunolabelling
2015 - IRG/WP 15-30674
The preservative efficacy of organic biocides is strongly related to their capacity of penetration and retention within wood tissues. The specific detection of the pyrethroid insecticide cypermethrin is currently obtained after extraction followed by chemical analysis by chromatography techniques. However visualizing the insecticide molecule within the wood structure requires specific probes toget...

Effect of Furfurylation on Shear Strength of Bond Line and Screw Withdrawal Resistance of Beech and Fir Wood
2016 - IRG/WP 16-40757
The aim of this study was to investigate the effects of furfurylation on shear strength of bond line and screw withdrawal resistance of beech (Fagus orientalis) and fir (Abies alba) species. In this regard, specimens with two different values of furfurylation i.e. low (fir 14% and beech 20%) and high (fir 38% and beech 65%) levels were prepared and evaluated in comparison with untreated specimens....

Hibernation or spring awakening? – The research on wood durability and protection in marine environment
2018 - IRG/WP 18-10929
Wooden structures in marine applications are exposed to severe degradation conditions caused by mechanical loads and wood degrading organisms. The present paper presents the use of wood in marine environments in Europe from a wood protection perspective and gives an overview over relevant research topics. It compiles the most relevant literature with an emphasis on new wood protection methods and ...

Degradation of Eucalyptus transmission poles varies across regions in Zambia
2018 - IRG/WP 18-30727
Evidence from literature shows that Eucalyptus poles treated with creosote last over 30 years before replacement. However, in Zambia, the life span of such poles has reduced to 5-10 years. The aim of this study was to investigate factors associated with degradation of treated Eucalyptus poles and how these varied across regions in the country. A total of 1200 poles were assessed in three differen...

In-line quality control of the film thickness in industrial coating processes for exterior cladding
2018 - IRG/WP 18-40835
The production of industrially coated wood cladding has been strongly increasing in Scandinavia during the last years. In the beginning of this development, industrial coating processes included solely the application of pigmented primers; these however provide only a short protection of the wood surface and the application of a top coat is required during the first 6 to 12 months after mounting t...
