Geopolymer as a fixation method for tannin-based wood preservatives
2023 - IRG/WP 23-30774
This study aims to test if a second step impregnation with a geopolymer solution can fix Colatan GT10, a commercial extract rich in tannins, to wood, reducing their leaching and improving their performance as wood preservatives. Scots pine sapwood specimens of 40×10×5 mm3 were impregnated with Colatan GT10 tannin mix, geopolymer, and as combined treatment Colatan GT10 with subsequent geopolymer ...

Hydrothermal liquefaction of spent mushroom substrate as a source of antifungals
2023 - IRG/WP 23-30791
The aim of this study was to characterize the chemical composition of hydrothermal liquefaction (HTL) products from the spent mushroom substrate (SMS) of Agaricus bisporus (Lange) Imbach and Pleurotus ostreatus (jacq.) P. kumm. using high-resolution 1H nuclear magnetic resonance (NMR), and assess the antifungal properties of these thermal decomposition liquids against wood decaying fungi (Coniopho...
