Summary: Consolidation improves the cohesion of stones and preserves stone-built heritage. However, it also modifies other characteristics that affect stone vulnerability to salt crystallization, especially in porous limestones. This study evaluates the compatibility of alkoxysilanes and phosphate-based treatments with a historic porous limestone in both short-term and medium/long-term perspectives. The findings reveal the potential risks of salt entrapment and development of subflorescences when using consolidants, highlighting the importance of addressing consolidation of damaged stones with proper compatibility.

Summary: Using superhydrophobic coatings can prevent the undesired translocation of marine microorganisms during sailing and excessive ship hull repairment due to biofouling. However, the anti-microbial performance of existing non-wettable materials is still in its early stages when exposed to underwater currents and colonizing activity. This study evaluates the potential of two mechanically durable water-repellent soot coatings in inhibiting bacterial proliferation in real-life outdoor conditions for the first time. The observed selective anti-fouling behavior is attributed to differences in cell envelopes, oxidative stress, and soot-mediated formation of toxic ammonia molecules.

Summary: This research aimed to evaluate the changes in surface properties of functional clothing materials with water-repellent finishes after washing. The results showed significant changes in the properties, depending on the material composition, structure, and type of finish. The PFC-free finish was found to be the least resistant to washing, and increasing washing frequency led to a gradual decrease in water repellency.

Summary: Graffiti vandalism is a harmful phenomenon for buildings and cultural heritage, and new non-invasive chemical approaches are being explored to combat this issue. This study tested two commercial anti-graffiti products on natural building materials and found that the nanotechnological product Ector was more effective, although its permanent nature limits its applicability to cultural heritage. The less effective Nord Resine could be used in cultural heritage protection due to its sacrificial properties.

Summary: This study proposes a method to achieve high sensitivity and long-term stability of metal-oxide gas sensors in highly humid environments, by increasing surface area, adding catalyst, and altering operation temperature. The use of PFOTS coating on porous SnO2 film results in superhydrophobicity and maintains this morphology under high humidity conditions and operating temperature, improving sensor performance.

Summary: In this study, the potential use of rice husks from different regions of Tanzania via supercritical water gasification (SCWG) was investigated. The physical and chemical characteristics of the rice husks were evaluated and correlated with their geographical factors. SCWG was conducted using a specific temperature, feed concentration, residence time, and catalyst loading. The results showed that the fabricated catalyst was suitable for the simultaneous production of gaseous and liquid biofuels from rice husks through the SCWG process.

Summary: In this study, four types of ZnO SPS were fabricated using different zinc sources, with ZnO nanoribbons SPS showing the longest delayed icing time at -5°C. However, the anti-icing ability of ZnO nanoribbons SPS decreased significantly with decreasing temperature. This work provides practical application for enhancing the anti-icing ability of Cu-based PCB in electronic packaging.

Summary: Myths and legends related to geological phenomena or stunning landscapes in the Ardennes Massif represent an important intangible geo-cultural heritage, adding an extra dimension to the holistic experience of geoheritage. Legends about characters like Emperor Charlemagne and Saint Remacle, as well as mythical figures like the Four Sons of Aymon, are rooted in the local geology and have even given their names to official geological formations. Other folktales involving creatures like dwarfs and witches have indirect links with geological curiosities, presenting a rich potential for geotourism development.

Summary: This study compared the bioreceptivity of two Lutetian limestones and their restoration stone, finding that Savonnieres stone had a weaker bioreceptivity for bacteria than Lutetian stones, but was more susceptible to colonization by other microorganisms. The results suggest that Savonnieres stone may experience more severe bioweathering compared to Lutetian stones.

Summary: This study characterized limestone lithotypes from Bizerte region in extreme North of Tunisia to investigate their weathering resistance and damage from thermal shock cycles. Infrared thermography (IRT) monitoring was conducted to assess the correlation between cooling rate index (CRI) and physical or chemical characteristics of the rocks. Statistical clustering identified four classes based on porosity values. The study highlighted the validity of CRI as an indirect parameter for estimating low porous stones properties undergoing thermal weathering.

Summary: Phototrophic microorganisms can easily grow in underground heritage sites, causing biofilm growth. This study aims to limit biofilm growth on chalk substrates using biocidal treatments based on POM-ILs. The experiments show that POM-IL coatings are more effective than commercial biocidal treatments and can sustain prevention of biofilm growth on wet chalk.

Summary: Rock-based materials exposed to outdoor environments are often colonised by microorganisms, causing damage to the stone. This study examined the use of biocidal coatings to prevent biocolonisation of calcareous stones. The experiments found that the coatings did not affect the porosity or water vapour transfer of the stones, and were effective in preventing colonisation by algal biofilms. However, fungal mycelium and phototroph colonisation was still observed on both coated and uncoated stones. The correct concentration of the coatings is important for achieving a balance between porosity, color variation, and long-term biocidal effects.

Summary: The study compared pre-Columbian cultural affiliations in the Lesser Antilles by analyzing three ceramic series from Guadeloupe, revealing the differences in inclusions and suggesting a gradual diffusion of grog temper use from the Guianas. This challenges the commonly accepted idea that Troumassoid developed smoothly from locally present Saladoid ceramic series without external influence.
