Application of diverse hyperspectral imaging systems for evaluation of heritage objects
2020 - IRG/WP 20-10971
Advanced imaging techniques are able to non-invasively characterize, monitor and evaluate the impact of conservation treatments on cultural heritage (CH) objects. In this specific field, hyperspectral imaging (HI) allows non-destructive characterization of materials by identifying and characterizing colouring agents, binders and protective coatings as constituents of an object’s original constru...

Extraction, identification and antifungal activity of polar extractives originated from various wood species
2020 - IRG/WP 20-20673
Extractives are non-cell wall small molecules present in wood and other lignocellulosic materials that can be removed by solvents. Although they represent a minor fraction in comparison with the structural cell wall components, they are an important source of functional groups or molecules with bioactivity or antioxidant properties, that could be used in medicine, cosmetic or wood preservation. T...

Dynamics of fungi colonization on the surface of Scots pine wood during natural weathering in different European climate zones
2022 - IRG/WP 22-10984
Wood The presence of fungi leads to biomaterial decay and/or changes in aesthetical appeal. The start of fungi colonization as well as the following growth on wood are primarily influenced by four factors: ambient temperature, moisture history of the object, access to oxygen, and intrinsic properties of the exposed wood, considered here as a source of nutrients for microorganisms. A prevalence of ...
