Summary: Monodispersed micrometer-sized Cholesteric liquid crystal (CLC) droplets were prepared using a flow-focusing microfluidic device for the detection of protein bovine serum albumin (BSA). The PVA/SC12S stabilized micro-sized CLC droplets (CLCPVA/SC12S) exhibited flashing spots with red reflection, and the configurational change from red reflection flashing spots to a central spot of red reflection was effective in detecting BSA in an aqueous solution with a limit of detection of 0.15 μM. The electrostatic interaction caused by the adsorption of negatively charged BSA on the positively charged CLC droplets was found to change the arrangement of CLC molecules in droplets from flashing spot to central spot reflection.

Summary: The heteroprotein complex formed by bovine serum albumin and lysozyme at the air-water interface was studied under varying subphase pH conditions. The research found that a more stable film was formed at a pH close to 9.2, with unique morphological changes. This suggests that pH close to 9.2 is the optimal condition for the formation of stable protein complexes.

Summary: This study investigated the impact of phosphate buffer concentration on the surface tension of bovine serum albumin solutions. The results showed that lower buffer concentrations slowed down the relaxation of surface tension and increased the equilibrium surface tension, while higher buffer concentrations accelerated the relaxation and decreased the equilibrium surface tension. Additionally, the dynamic surface tension of BSA solutions relaxed the slowest at a buffer concentration of 0.3 mM.

Summary: Excess nitrate in water is a challenge for ecosystem and human health. This study used bovine serum albumin (BSA) as a supplementary material to improve the rate of sulfur autotrophic denitrification. The experiment showed that a larger amount of BSA significantly increased the denitrification rate. In a packed bed reactor, sulfur particles with 1% BSA had a faster start-up and better denitrification performance compared to the control group.

Summary: It was found that bovine serum albumin (BSA) and glycosylated bovine serum albumin (GBSA) prepared in a nature deep eutectic solvent system show stronger interactions with kaempferol (Kae). GBSA-Kae nanoparticles (NPs) exhibited higher zeta-potential values, lower polydispersity index (PDI), higher encapsulation efficiency (EE), and loading capacity (LC) compared to BSA-Kae NPs. Structural characterization and stability analysis confirmed the stability of GBSA-Kae NPs. This study provides a theoretical foundation for improving the solubility and stability of Kae during its delivery and transport.

Summary: This study aimed to investigate membrane fouling characteristics and determine control strategies for concentrating liquid desiccants using membrane distillation. Two different desiccants, lithium chloride and potassium formate, were tested. Results showed that water flushing was the most effective method for controlling membrane fouling. Air backwashing and membrane spacer had limited cleaning effects. Therefore, combining water flushing with membrane spacer can maintain high flux and low fouling tendency.

Summary: Premature failure of AFC chains due to corrosion is a significant cause of unplanned downtime on longwall equipment. The impact of reverse osmosis (RO) water treatment on the corrosion of AFC chains is unclear. This study investigates the direct effects of RO water on AFC chain corrosion and finds that although dam water has higher levels of calcium, chloride, sulphate, sodium, and magnesium, RO water more vigorously dissolves calcium carbonate scales, leading to increased corrosion of AFC chains.

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.
