The Slovenian Research Agency approved funding for a 3-year research project titled "Effects of lignin degradation on paper-based materials in extreme conditions". The project will explore the effect of lignin degradation on cellulose-based materials in two “extreme” contexts: during composting and long-term environmental degradation. The variables affecting the degradation pathways as well as the degradation [...]

Researchers from the Faculty of Chemistry and Chemical Technology of the University of Ljubljana and the National Museum of Slovenia recently published the paper Non-Destructive Detection of Pentachlorophenol Residues in Historical Wooden Objects. As a natural material wood is important in many heritage collections. Because of its susceptibility to biodegradation, it has often been chemically [...]

Ageing of historical objects often results in changes in the optical properties of the constituent materials. Imaging spectroscopy (IS) can be a valuable tool for monitoring of such changes although it has so far rarely been used in a quantitative manner. The purpose of research presented in this paper is to evaluate its detection limit [...]
