Summary: Novel humidity sensors based on montmorillonite, kaolinite, and composite films coated on micro-cantilevers were prepared to measure the relative humidity values. The humidity-sensing properties were investigated and a linear correlation between humidity change and deflection was observed for montmorillonite, kaolinite, and the mixed-clay mineral film. Montmorillonite showed better sensitivity compared to kaolinite, with the mixed-clay mineral film falling in between. This research provides a feasible and effective approach to constructing high-performance micro-cantilever humidity sensors based on clay minerals at room temperature.

Summary: In recent years, researchers have extensively studied multifunctional inorganic-organic hybrid materials to determine their potential effects on reactivity. This study designed and characterized a hybrid material by combining photocatalytic TiO2 nanoparticles with sodium surfactin (SS), a biosurfactant with high affinity for metal cations and antimicrobial properties. The synthesis methodologies and different TiO2:SS weight ratios were investigated to understand their effects on colloidal, physicochemical, and functional properties. The breaking point between TiO2 and SS single-component trends was identified and different ranges of applicability were determined. At low SS contents, the hybrid material showed preserved photocatalytic properties and additional antimicrobial effects, while at high SS contents, TiO2 photoactivity was inhibited and the hybrid material could be used as a UV blocker. Around the breaking point, the hybrid material exhibited high surface area, NOx depletion, and improved adhesion for antibacterial coatings, making it suitable for water/soil remediation applications.
