Summary: This paper analyzes the pottery assemblages from the site of Arslantepe in Turkey using thin-section petrography and X-ray wavelength dispersive fluorescence techniques. The study reveals the presence of both continuity and change during the Late Bronze and Iron Age periods. The use of volcanic-based recipes for painted vessels shows continuity, while increased exploitation of geological deposits and standardization of paste recipes indicate changes. Importantly, the study also highlights extra-regional exchanges during both the Late Bronze Age and Middle Iron Age levels.

Summary: This study investigates the preservation of the Imperial Roman Baths in Sagalassos, Turkey. Through comprehensive characterization and multiscale assessment of bricks and mortars, the research explores effective preservation methods. Experimental results indicate that although the interface between building materials weakens over time, individual materials still maintain a higher strength. Finite element modeling is used to understand the damage mechanism, showing that brick failure is caused by accumulated tensile stresses at the brick-mortar interface. Global sensitivity analysis reveals that thicker bricks result in better confinement and smaller tensile stresses.

Summary: The R-3 test was applied to validate the chemical reactivity of supplementary cementitious materials (SCMs). The study found a strong correlation between cumulative heat release and bound water determined by the R-3 test method. While conventional SCMs followed a similar trend in mortar compressive strength development, highly reactive calcined kaolinitic clays were an exception. The study suggests proposing reactivity threshold values for classification of SCMs based on the R-3 test results.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.
