Summary: In this study, three deep eutectic mixtures (DES) were used as mediums to synthesize glucose laurate and glucose acetate. Lipases from Aspergillus oryzae (LAO), Candida rugosa (LCR), and porcine pancreas (LPP) were employed as catalysts. The results showed that DES did not deactivate the lipases when used as medium. For transesterification reactions, combining LAO or LCR with DES 3 resulted in efficient production of glucose laurate, while LPP performed best in DES 2 for glucose acetate synthesis. Substituting vinyl laurate with vinyl acetate led to different behaviors, with LCR and LPP showing better catalytic activity in DES 1 for glucose acetate production. LAO had lower activity, with only around 40% product yield in DES 3. These findings highlight the potential of biocatalysis combined with greener solvents for the synthesis of differentiated sugar fatty acid esters.

Summary: The shift towards lesser-polluting and carbon-efficient energy systems has made biodiesel an attractive option for sustainable bioenergy. However, the lack of feedstock flexibility and reliance on vegetable oils for production poses a challenge in resource allocation, leading to potential competition with food supply. Exploring low-grade non-edible oil sources and improving catalyst selection for glycerolysis reactions are key factors in enhancing biodiesel profitability and sustainability in the future.

Summary: Polyphenols, bioactive compounds commonly found in plants, have high antioxidant power and are correlated to many health benefits. Traditional and novel extraction methods have been investigated for the extraction of polyphenols. The optimal extraction temperature for subcritical water extraction (SWE) can reach as high as 100-200 degrees C, leading to high yields and antioxidant capacities. The main factors affecting the extraction of polyphenols include thermal degradation, formation of Maillard reaction products, selection of plant matrix, and extraction conditions. The correlation between total phenolic content (TPC) and antioxidant activity lacks consensus.

Summary: The industrial sector consumes about 40% of global energy, and a significant amount of waste energy is discarded at low temperatures. Thermochemical heat transformers (THT) can recover this low-temperature waste heat by storing and releasing it at a higher temperature. This allows for waste heat reintegration into industrial processes, improving energy efficiency and reducing greenhouse gas emissions.

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.
