Summary: This study investigates how small changes in the lower size range of AuNPs affect the photoactivity of Au/TiO2, aiming to maximize the performance of low-metal-loading photocatalysts. Au/TiO2 photocatalysts prepared by precipitation-deposition methods and a speciation-controlled incipient wetness impregnation method exhibited significantly higher NOx elimination capacity than pristine TiO2. Among the photocatalysts, the speciation-controlled incipient wetness impregnation method achieved the highest gold dispersion and Au-TiO2 contact perimeter, providing the most active photocatalysts, confirming the positive effect of AuNPs size reduction. Additionally, it is proposed that the adsorption of nitrogen oxides species on gold plays a relevant role in the NO photooxidation process.

Summary: Super-oleophobic TiO2/SiO2 composite coatings were achieved through a simple spraying method, with dendritic structures playing a critical role in providing the re-entrant geometry required for oleophobic surface. The introduction of micron-scale TiO2 particles and nano-scale SiO2 particles provided a dual-scale rough structure for the coating, resulting in superior repellence to high and low surface tension liquids as well as long-term durability. This design strategy may offer useful guidance for the fabrication of particle-based spray-coated super-oleophobic surfaces.

Summary: This study investigated the photocatalytic degradation of rhodamine B and phenol using TiO2/SiO2 composite nanoparticles under visible-light irradiation. The results showed that the composite material achieved 100% and 43.19% degradation of rhodamine B and phenol, respectively, within 210 minutes. The major reactive oxygen species involved in the photocatalytic degradation were found to be O-2(-), h(+) and e(-) for rhodamine B, and ?OH radicals for phenol. The TiO2/SiO2 composite catalyst demonstrated stable degradation efficiency after five cycles of reuse.

Summary: The study explored the effects of CO2 exposure on TiO2-incorporated Portland cement, revealing that while the incorporation of TiO2 positively impacted the hydration process and early strength development, it did not significantly enhance strength at a later age. Additionally, exposure to CO2 led to a reduction in the NOx-removal performance of the samples, as the TiO2 particles on the surface were covered by calcium carbonate formed during carbonation.

The use of anatase titanium di-oxide with a high percentage of {001} facets improved the antipollution properties compared to similar sols based on P25. The treated titania nanosheets showed improved photocatalytic activity and effectively reduced concentrations of NOx, soot, and organic dyes under simulated sunlight radiation.

Summary: Accordion-like Ti3C2Tx MXene was successfully prepared via chemical etching, and TiO2 nanocrystals were grown on Ti3C2Tx nanosheets by in-situ oxidation using a powerful alkaline solution. The ratio of Ti3C2Tx and TiO2 was optimized, resulting in TiO2/Ti3C2Tx composites with excellent photocatalytic activity, especially for NO removal. The microstructure of TiO2/Ti3C2Tx composites contributed to the improvement of the separation and transfer efficiency of photogenerated carriers. The composite sample synthesized at 75 degrees Celsius showed the best NO removal efficiency, removing 70% of NO at a concentration of 600 ppb. This study offers a new approach for preparing high-performance MXene-based photocatalysts.

Summary: Single-phase oxygen stoichiometric LaMnO3 and doped La(0.8)A(0.2)MnO(3) (A = Ca, Sr, Ba) perovskites were prepared by a simple one-step auto-combustion method. Cation-deficient LaMnO3+delta and La(0.8)A(0.2)MnO(3+delta) were obtained by calcination of the former samples in air at 750 degrees C. The catalytic activity of these oxides is influenced by the Mn4+/Mn3+ molar ratio on the surface of the samples and the cation-deficiency of the bulk perovskite structure.

Summary: Many concrete structures in need of repair and protection can be treated using silane-based impregnation treatments, which produce silica and C-S-H gels and can be modified to create multifunctional treatments that also protect from water ingress. However, standard material validation may not always be representative of on-site application due to substrate properties and changes over time. In this study, three innovative silane-based impregnation treatments, two of which have superhydrophobic properties, were evaluated on mockup specimens that simulate the properties of cementitious materials from different heritage structures in Europe. The treatments showed compatibility, minimal aesthetic alterations, and improved mechanical properties.

Summary: Hydrophobic mortars are produced by combining a silane-based admixture with the pre-treatment of the aggregates with an alkoxysilane-ended fluoropolymer. A comparative study is conducted to evaluate the impact of different components and curing conditions on the hydrophobicity, mechanical performance, composition, and micro-structure. The combination of both strategies allows achieving hydrophobic properties under varying curing conditions, compensating for the limitations of silane admixtures.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
