In the last years, several techniques have been proposed, attempted and even routinely tried on research on assessing the deterioration of stone of Cultural Heritage buildings and monuments. We test here the use of hand-held gamma-ray spectrometry (GRS) to assess the decay of stone in two Heritage buildings. GRS is a non-destructive technique widely used in mineral exploration that provides an estimate of the environmental gamma radiation dose but also of the content of some radioisotopes of uranium, thorium and potassium in rocks and minerals. Such radioisotopes are present in very variable contents depending on the rock type. They have a different behavior when a stone overcome weathering processes, being usually the K and U leaching, while Th tends to be considered as an immobile element. We have tested GRS on two historical buildings built with granite blocks of the Peninsula of Barbanza (Galicia, NW, Spain): Santiago de Lampón and San Cristovo de Abaqueiro. The studied buildings show a mild deterioration in some façades, being an interesting study case. Measurements were carried out on the four façades of both buildings at on ashlars located at heights of 0.5, 1.5 and 2 m, above the ground, for comparing the possible effect of capillary water from underground on the weathering degree of the ashlars. The comparison of the content in K, U, and Th provides interesting results, that seems to be useful to assess the degree of decay of ashlars in buildings that shows slight differences in decay, being a non-destructive tool.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"71 ","pages":"Pages 20-29"},"PeriodicalIF":3.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, numerous tremolite jade artifacts unearthed from archaeological sites exhibit various deterioration patterns due to natural weathering and human activities. Among these, powdering is the most detrimental form of degradation, significantly affecting the physical characteristics of artifacts, as well as archaeological research and museum exhibitions. This paper develops a novel hybrid siloxane oligomer as a potential consolidant for powdered tremolite jade artifacts and compares it with traditional consolidants, including acrylic resin and ethyl silicate. Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and X-ray fluorescence (XRF) analyses show that the jade samples used in the experiment are predominantly composed of tremolite. Various techniques are employed to evaluate and compare the effectiveness of the three consolidants, including color variation tests, open porosity tests, contact angle measurements, peeling tests, hardness tests, ultra-depth-of-field microscopy, and scanning electron microscopy (SEM). The novel hybrid siloxane oligomer demonstrates superior consolidation effects, with consolidated samples showing significant improvements in mechanical properties, reaching a Leeb hardness of 163 HL, while maintaining color variations within acceptable limits (ΔE = 3.87).

Despite the application of desalination, deacidification, and drainage treatments to archaeological wood following excavation, the effects of such environments on wood are irreversible. To understand the effects of moisture content, acidic environments, and insoluble salts (Fe₂S) on the mechanical properties of marine archaeological wood, this study employed molecular dynamics simulations to analyze the tensile performance of wood cell walls under various conditions. The results indicate that, compared to completely dry wood, water molecules can significantly enhance the tensile strength of wood cell walls. However, in systems with a 12 % moisture content, the tensile strength is lower than in systems with a 4 % moisture content. The worst tensile performance of wood cell walls occurs in acidic and salt-deposition conditions. This is mainly due to the fact that an appropriate amount of moisture enhances the interconnections between wood fibers, whereas acidic and salt deposition conditions disrupt these connections. Additionally, the impact of varying quantities of moisture molecules on the mechanical properties of wood also varies. Further exploring the optimal moisture content for the preservation of waterlogged wooden artifacts, using archaeological fir wood as an example, we constructed models of amorphous wood fibers and matrices with moisture content varying from 0 % to 36 %. The results indicate that the system with 8 % moisture content exhibits optimal mechanical performance. Specifically, the shear modulus and chain-direction elastic modulus reach 4.52 GPa and 12.93 GPa, respectively, representing an increase of 25.2 % and 45.1 % compared to completely dry systems. The molecular mechanism by which moisture content influence the mechanical properties of wood was analyzed through parameters such as mean square displacement, diffusion coefficient, and free volume. It is hypothesised that an appropriate amount of water molecules can fill the gaps between fibers, enhancing the inter-fiber bonding and stiffness, and thereby improving the mechanical properties of wood. However, as water molecules continue to be added, this positive effect diminishes. The objective of our study is to gain insight into the mechanical behavior of archaeological wood cell walls from a molecular perspective. This paves the way for multiscale studies to determine the optimal moisture content for preserving wooden artifacts and to identify environmental conditions that can maximize the mechanical performance of archaeological wooden objects.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"70 ","pages":"Pages 431-440"},"PeriodicalIF":3.5,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
