Summary: A tubular porous borosilicate membrane contactor was studied for ozone gas/water mass transfer and removal of contaminants in water. Increasing the gas and liquid flow rate improved the mass transfer efficiency, with the main resistances being in the water phase boundary layer and the membrane. The contactor showed good feasibility in removing contaminants, but photocatalytic ozonation did not significantly enhance treatment performance.

Summary: In this study, Al2O3 ceramic membrane was modified to be hydrophobic by grafting 1H, 1H, 2H, 2H-per-fluorodecyltriethoxysilane, and its properties were characterized in detail. The CO2 capture performance of the modified ceramic membrane was investigated through experiments. Results showed that the wetting resistance of the modified membrane was significantly improved, and the contact angle increased from 49.8 to 130.9 degrees. With the use of ethanolamine (MEA) as an absorbent, the CO2 mass transfer rate and capture efficiency using the modified hydrophobic ceramic membrane were greatly increased compared to the original membrane. After 72 hours of immersion in MEA solution, the quality and pore size of the ceramic membrane did not show significant changes. This study provides valuable insights for the industrial application of gas-liquid membrane contactors with ceramic membranes for CO2 capture.

Summary: The study on the oxidation removal of nitric oxide in a ceramic hollow fiber membrane contactor showed that efficiency is influenced by various factors such as operating temperature, gas channel width, and effective membrane length. It is not recommended to improve reduction efficiency by increasing membrane tube diameter and operating pressure, while moderate changes in gas flow rate, absorbent concentration, and gas channel width are appropriate.

Summary: Ozonation processes using membrane contactors show promise for removing organic micropollutants, with good control of the transferred ozone. A 3-D model was developed to study ozone transfer in water through single and multi-fiber membrane contactors, and can be used to optimize bubbleless processes and scale up membrane contactor processes for ozonation applications. Hydrodynamics was found to be a crucial factor for ensuring good ozone distribution and pollutant treatment. The transferred ozone does not increase proportionally with increasing membrane length or residence time, necessitating a careful balance between contactor length and fibers number.

Summary: Membrane gas-liquid contactors are developed to enhance gas absorption process efficiency and reduce energy consumption, by combining membrane separation and amine absorption technologies. A major technical challenge is the wetting of membrane pores by solvent, which lowers mass transfer coefficient. However, factors like solvent selection and operational temperature are also crucial for success.

Summary: Aeration is a mass transfer process that disperses gas into a liquid, typically using a microporous device. The surface wettability of the gas/solid interface significantly affects bubble size, which is often overlooked. A superhydrophilic/superhydrophobic Janus aluminum foil fabricated by laser microstructuring improves gas dissolution rate and has broad applications in wastewater treatment, energy production, and aquaculture.

Summary: This study proposed an experimental method to estimate the relative membrane mass transfer resistance by comparing results obtained using HFMC with those obtained using WWC, successfully applied for determining optimal pore structure for increasing CO2 absorption. The results showed that R-m(HFMC) contribution ranged from around 90% to 27% of overall mass transfer resistance and was related to pore structure properties.

Summary: Casein hydrolysate (Pep) is found to be a dispersant for poorly water-soluble drugs and nutraceutical ingredients, forming two types of complexes based on permeability: hydrocolloids and non-hydrocolloids. The size and hydrophobicity of the molecules in the complexes determine their permeability, with pH values also affecting the permeability of certain complexes. Stoichiometry and association constants for complexes can be determined using fluorescence quenching method.

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.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. 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.
