Summary: Adsorption of a cationic surfactant on montmorillonite encapsulated in alginate hydrogels composite reveals different adsorption conformational arrangements with increasing surfactant concentration, even in unexpanded clay. The presence of cationic and anionic biocides affects surfactant adsorption differently, with anionic contaminants having no impact. The composite material shows potential for water remediation due to easy extraction from aqueous media.

Summary: The research thoroughly investigated the adsorption mechanism of three chemically-diverse micropollutants on CPN, showing that both anionic and cationic exchange sites coexist on the CPN and can adsorb simultaneously without compromising each other. The adsorption of non-ionic micropollutants was enhanced in the presence of charged micropollutants due to a synergistic effect. The study also demonstrated the efficient filtration of effluent organic matter and micropollutants from TWW by CPN columns compared to granular activated carbon columns.

Summary: In this study, fungal hyphae/carbonized quinoa starch porous carbon materials were successfully prepared using a biological self-assembly method. The resulting materials showed higher specific surface areas and pore volumes compared to quinoa starch-based porous carbon. Adsorption experiments demonstrated that the fungal hyphae/carbonized quinoa starch porous carbon materials exhibited higher adsorption capacities for model pollutants compared to the quinoa starch-based porous carbon. The removal rates of the pollutants remained above 50% even after multiple cycles. This study highlights the advanced nature of the biological self-assembly method and provides a new direction for the research and development of other microorganism composites.

Summary: The mucus layer serves as a physiological barrier that defends against invading agents. Its permeability is controlled by the size filtering and interaction filtering mechanisms. The presence of functional groups on the mucin proteoglycans determines the mucoadhesive/muco-penetration potential of drug delivery systems. Drug delivery across the respiratory mucosa faces challenges from mucociliary clearance mechanisms.

Summary: Coagulation-flocculation is an important treatment method to reduce operational issues caused by cyanobacterial blooms in surface waters at Drinking Water Treatment Plants (DWTPs). The search for good coaguflocculants that do not release intracellular toxins is necessary for sustainable production. This study examines the interactions between clay and polymers to develop efficient composites for use as coaguflocculants for Microcystis aeruginosa (M. aeruginosa) suspensions.

Summary: This study demonstrates that the in situ application of cationic polymers like polydiallyldimethylammonium chloride (PDADMAC) can regenerate the capacity of filter media to remove short-chain PFAS. Additionally, the application of PDADMAC reduces the release of colloids and prevents the re-entry of adsorbed PFAS into water.

Summary: The study assessed the properties of agar-containing thermoplastic sago starch (TPSS) at different loadings. The results showed that adding agar significantly improved the mechanical properties and thermal stability of starch-based thermoplastic blends, but slightly increased moisture absorption. The TPSS/agar blend has the potential to be used as a biodegradable material.

Summary: In this study, cationic polymer poly-epichlorohydrin-dimethylamine was successfully immobilized on natural attapulgite to enhance dye adsorption capacities, particularly for anionic dyes. The modified attapulgite displayed high adsorption capacities for anionic dyes, with the potential to completely remove reactive dyes from effluents in column operation modes. The treatment capacities of the cation-modified attapulgite were more than three times larger than those of activated carbon, demonstrating its potential for effectively treating dye wastewaters.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. 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.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
