G11: Evaluation and conservation of cultural heritage
Main field of activity: Development and implementation of the most advanced procedures for monitoring – investigation – diagnosis – treatment on different elements, categories of cultural heritage and different materials (stone, pigments, paper, parchment, wood, etc.). Mission: – Research activities in the laboratory and in the conservation sites as a result of the new requirements coming from the restorers and the specialists dealing with the practical conservation; – Use of advanced investigative techniques applied to establish the stage and degree of degradation of works of art, and recommendations regarding restoration and conservation operations; – Measurements on: the quality of the surfaces of the investigated parts, the study of the surfaces of very fragile monuments in a stage of accelerated degradation and the concentration of pollutants on the surfaces. Evolution of research directions: development of diagnostic and treatment technologies for the conservation and revitalization of the archaeological components of the cultural heritage: (i) Development of new micro- and nano-materials, new methods and technologies; development of new investigation techniques; (ii) Selection and characterization of historical materials; (iii) Evaluation of in situ materials and sampling of samples taken; (iv) Development of cleaning treatments for selected surfaces; (v) Polymer gel systems applied in conservation / restoration; (vi) Anti-slip and antimicrobial mats; (vii) Polymeric waste recovery compositions with improved properties.
