Summary: Detection of volatile organic compounds (VOCs) in exhaled breath is important for health assessment and disease diagnosis, but current small-sized VOC detectors lack sensitivity to detect low levels of VOCs. A proposed gas concentrator can effectively concentrate VOCs from exhaled breath to be detected by commercial VOC detectors, showing potential for disease diagnosis when combined with a gas analyzer or detector.

Summary: By modifying bamboo tar through polymerization, it acts as a new adhesive for preparing bamboo-charcoal-derived molding activated carbon (MBAC). Compared with pristine tar and other adhesives, the aromatization of tar with phenol increases its molecular weight, oxygenic functional groups, and thermal stability, resulting in improved bonding and pyrolytic crosslinking effect between charcoal particles, leading to higher mechanical strength, specific surface area, pore volume, and amount of oxygenic functional groups for MBAC.

Summary: The removal of VOCs from coal-fired power plants is crucial in reducing emissions into the atmosphere. Adsorption on activated carbon is an effective method but can be affected by factors such as temperature and the presence of other gases. Competitive adsorption may occur when SO2, water vapor, and fly ash coexist, impacting the overall VOCs removal efficiency. Selecting activated carbon with large micropore volume and extending adsorption time can enhance the VOCs removal process.

Summary: The study aimed to determine the optimal conditions for the preparation of magnetic activated carbons (mACs) from Sargassum sp. as adsorbents and catalytic supports. The mACs showed better adsorption capacity and degradation efficiency for antibiotics when prepared by the post-impregnation method compared to the pre-impregnation method. The physicochemical properties of the mACs were characterized using various techniques, and the use of Sargassum sp. was found to be promising for the removal of organic pollutants from polluted waters.

Summary: The study explores the application of pressure swing adsorption (PSA) for removing and recycling VOCs, with a focus on nonequilibrium time, effective length, and enrichment ratio. Various experiments were conducted to investigate the mechanism and industrial parameters of PSA, revealing that factors such as kinetic diameter, polarity, pore size, and boiling point influence the efficiency of VOCs removal. Methanol and acetone showed shorter effective lengths for complete removal compared to toluene, and the desorption performance was found to be related to desorption activation energy and the boiling point of the adsorbate. Ultimately, the study found that acetone had the highest recovery ratio among the three VOCs studied, presenting new opportunities for VOCs removal and recovery.

Summary: Metal-organic framework (MOF) UTSA-16 (Co) was shaped into pellets with binders of activated carbon (AC), silica, and 8% polyvinyl butyral (PVB)/ethanol solution. Increasing the percentage of UTSA-16 (Co) in the AC and silica pellets led to an increase in CO2 adsorption capacity and CO2/N2 selectivity. The stability of the pellets was tested by exposing them to SO2 and NO2, and the performance was further evaluated using AC composite pellets with UTSA-16 (Zn). The long-term stability of the pellet composites was examined through CO2 adsorption-desorption cycles, and the pellets were characterized using SEM, TGA, and the BET method.

Summary: Although the characteristic skunky odor of cannabis has long been discussed, its cause has been mistakenly attributed to unspecified skunky terpenes. Recent research has corrected this misperception and identified 3-methyl-2-butene-1-thiol (321MBT) as the primary compound responsible for the skunky odor in both industrial hemp and cannabis.

Summary: This study investigated the different forms of phosphorus in soil after long-term application of broiler litter and ammonium nitrate. It was found that the use of broiler litter increased the extractable organic phosphorus content, but also led to the accumulation of organic phosphorus in soil.

Summary: The study proposes a concept of a mobile 'all-in-one' system for on-farm swine depopulation and pathogen inactivation, using vaporized CO2 and heat treatment to broaden options for off-site carcass disposal and cleanup. The user-friendly model developed based on engineering principles estimates the required CO2 amounts and times, providing practical information for effective depopulation and pathogen inactivation. The model allows for input of dump trailer size, pig number, weights, and environmental conditions, and could be adopted for routine or mass depopulation/treatment/disposal with single or fleet units.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
