Summary: In this study, polyaniline/poly(styrene sulfonate) (PANI/PSS) nanocomposite and polyaniline center dot silver (PANI center dot Ag) nanohybrid thin films were successfully prepared for gas sensing of sexual pheromones from the neotropical brown stink bug. Both nanosensors showed similar sensitivities, but the PANI center dot Ag nanohybrid nanosensor had a lower limit of detection, making it a promising candidate for the detection of sexual pheromones. UV-vis and FTIR analysis confirmed the incorporation of Ag nanoparticles in the nanohybrid sensing layer, which contributed to the improved detection performance.

Summary: By using inter-facet edge (IFE) rich WO3 arrays in an electrolyte containing CO32-, reactive oxygen species (ROS), H2O2, and OH. are efficiently generated by water oxidation with total Faraday efficiencies of more than 90%. The IFE favors the adsorption of CO32- and reduces the adsorption energy of OH., while suppressing surface hole accumulation. In situ selective oxidation of benzyl alcohol using the formed OH. achieves a benzaldehyde production rate of approximately 768 μmolh(-1) with near 100% selectivity. This work provides a promising approach to enhance the efficiency and value-added product of oxidation reactions in aqueous solar fuel systems.

Summary: Wastewater containing dye can be effectively treated by using modified biochar (Biochar-FexOy) with a high adsorption capacity of 85.1 mg/g for methylene blue (MB) dye at pH 8. The enhanced adsorption performance of Biochar-FexOy can be attributed to its increased surface area, porosity, and deposition of metal ions. The adsorption mechanism involves electrostatic attraction, hydrogen bonding, & pi;-& pi; interactions, and possible cationic exchange. The adsorption capacity of Biochar-FexOy remains high even after 4 regeneration cycles, indicating its potential for practical dye wastewater treatment.

The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
