Determining the minimum water vapor permeability of exterior wood coatings by means of hygrothermal and decay models
2024 - IRG/WP 24-20717
The objective of this study was to determine the minimum water vapor permeability of exterior wood coatings for log homes using hygrothermal and decay modeling. The approach is based on a worst-case scenario assumption, namely a moisture trap at a given wood moisture content in a coated wall log. The minimum limit of vapor permeability of the coating system was determined by simulating the time re...

Screening of fungi capable of degradation of β-aryl ether bond from lignin model compounds by using highly fluorescent-emitting detection
2025 - IRG/WP 25-11081
Lignin is an aromatic polymer and composed of phenylpropane units polymerized by dehydrogenases in cell walls. Lignin has a complex chemical structure with C-C and C-O-C bonds, and it is difficult to decompose lignin structure by microorganisms in natural conditions. For the microbial degradation of lignin structure, wood decay fungi can non-specifically degrade the lignin polymeric structure by o...
