“…Figure a–c presents the internal cross-sectional structure of the imprint sample. The grayscale of the image corresponds to the X-ray absorption coefficient of the substance, and different phases can be distinguished according to the absorption coefficient; thus, the composition of different phases can be clearly observed through three-dimensional rendering. , Figure shows that the surface of the imprint sample had only one phase, and its internal cross-sectional structure showed the same state, which indicated that the density of the fabric imprint was close to the density of the soil beneath the imprint and the fabric had been completely soiled.…”

The extraction and identification of silk residues in tombs is of great significance for studying the distribution and spread of early silk. However, the complex organic matter in the tomb hinders the accurate identification of silk. In this study, a doubleantibody sandwich enzyme-linked immunosorbent assay (ELISA) based on immunomagnetic beads (IMBs) was developed for the rapid enrichment and detection of silk residues. The doubleantibody sandwich ELISA method established by pairing the IMBs prepared by the silk fibroin monoclonal antibody SF-3 and the silk fibroin monoclonal-labeled antibody bio-SF-1 had the highest detection sensitivity, with a linear detection range of 10 to 10 4 ng mL −1 and a detection limit of 5.12 ng mL −1 . This method was excellent in the extraction and analysis of silk residues from archaeological imprints and soil samples and successfully identified silk residues in samples at the final stage of silk degradation (physical invisible silk). The proteomics analysis results demonstrated the feasibility and practicability of this method.

“…The pore-clogging inhibits the vapour transport from inside to the external environment [5]. Furthermore, the non-adhesion of the polymer along the pore's surface does not reduce the interaction with water, which is retained and/or absorbed, representing a drawback for the stone protection [23]. This justifies why Fluoline HY significantly reduces the water vapour permeability of the stone, while also conferring poor water repellence.…”

A New Methodological Approach to Correlate Protective and Microscopic Properties by Soft X-ray Microscopy and Solid State NMR Spectroscopy: The Case of Cusa’s Stone

Hydrophobic treatment is one of the most important interventions usually carried out for the conservation of stone artefacts and monuments. The study here reported aims to answer a general question about how two polymers confer different protective performance. Two fluorinated-based polymer formulates applied on samples of Cusa’s stone confer a different level of water repellence and water vapour permeability. The observed protection action is here explained on the basis of chemico-physical interactions. The distribution of the polymer in the pore network was investigated using scanning electron microscopy and X-ray microscopy. The interactions between the stone substrate and the protective agents were investigated by means of solid state NMR spectroscopy. The ss-NMR findings reveal no significant changes in the chemical neighbourhood of the observed nuclei of each protective agent when applied onto the stone surface and provide information on the changes in the organization and dynamics of the studied systems, as well as on the mobility of polymer chains. This allowed us to explain the different macroscopic behaviours provided by each protective agent to the stone substrate.

“…The TwinMic beamline 20 at Elettra Sincrotrone Trieste (Trieste, Italy), which combines STXM in the 400-2200 eV energy range with low energy XRF (LEXRF) microscopy, 27,28 has attracted the interest of several scientific communities worldwide. [29][30][31][32][33][34][35][36][37] Since its first design and initial project, the TwinMic microscope has been conceived as a multi-modal/multi-technique instrument, 27,38,39 where for instance, STXM could be combined with full-field microscopy. In this paper, we focus on AFM integration within the existing TwinMic microscope.…”
