The Effect of Flavonoids on Colour and Spectral Changes of the Wood Surface Caused by Heat Treatment or Ultra-violet Irradiation
2006 - IRG/WP 06-40341
Both heat treatment and UV irradiation can cause discolouration and change in the spectral properties of wood surface. Some of the characteristic flavonols have significant role on colour and spectral changes, despite of their relative small quantities in wood.
Colour changes and spectral properties of natural and extracted black locust (Robinia pseudoacacia L.) and poplar (Populus nigra L.) were...

Effect of nanoparticle impregnation on the biological durability of wood
2022 - IRG/WP 22-30772
This study evaluated the efficacy of five different nanoparticles (zinc-oxide, zinc-borate, silver, copper-oxide, copper-borate) applied with different concentrations against the brown rot Coniophora puteana and the white rot Coriolus versicolor. The generally effective nanoparticle treatments were the combinations containing borate in its chemical structure. However, only zinc-oxide and silver na...
