Understanding how to safely and effectively remove soot from cultural heritage objects is a pressing challenge—particularly in the aftermath of fires, where artworks, archives, and historic interiors may be exposed to layers of complex, highly variable residues. Within the EU Horizon MOXY project, researchers are developing an innovative cleaning method based on atmospheric, plasma-generated monoatomic […]

A new study by researchers from CNR-INO, in collaboration with colleagues from CNR-ISPC Catania and the Opificio delle Pietre Dure, has just been published in Talanta (Elsevier). The paper presents an advanced analytical workflow developed within the DIAGNOSE project to study and preserve daguerreotypes—the earliest photographic images, renowned for their unique beauty but exceptional fragility. Daguerreotypes often suffer from complex degradation phenomena that obscure […]
A recent study, “Spatially registered 3D and sequentially shifted Raman mapping for painted surface characterization“, presents a new platform that integrates 3D surface scanning with SSETM Raman mapping to analyse painted surfaces non-invasively and with high spatial accuracy. Designed for hardware-registered data acquisition, the system enables automated macro-Raman acquisition, ensuring precise focus and co-registration even […]
Published on Science of the Total Environment, May 2025 | DOI: 10.1016/j.scitotenv.2025.179494 Michelangelo’s “secret room” beneath the Medici Chapel in Florence has always fascinated visitors and scholars with its stunning charcoal sketches. But recently, something unexpected has caught researchers’ attention: a curious pink discoloration creeping across the lower parts of its walls.Was this a pigment? […]
