Post-Doc : Innovative bio-based methods for the preservation of waterlogged archaeological wood and iron artifacts (Neuchâtel)

Logo Universite Neuchatel

This project focuses on innovative bio-based methods for the preservation of waterlogged archaeological wood and iron artifacts. The research team will exploit the unique proper-ties of some bacteria or metabolites for anticipating the extraction of sulfur compounds from wood when it is still wet and in parallel for preventing iron artefacts from the for-mation of voluminous unstable corrosion products upon exposure to oxygen. To this pur-pose, three different strategies will be adopted: 1) oxidation of sulfur species, 2) com-plexation of iron species and 3) iron reduction.
