However, their further development is hindered by critical challenges, such as severe dendrite growth and side reactions. Meanwhile, the performance improvement of AZIBs using common single-function electrolyte additives is limited. In this study, a natural proline with dual functionality is introduced to regulate the electrochemical properties of the interface, guide uniform deposition of Zn, regulate the solvation structure of Zn<sup>2+</sup>, and induce exposure of the Zn (002) surface. After testing, the modified Zn symmetric cell exhibits exceptional durability of more than 1700 h at 4.0 mA h cm<sup>–2</sup>/1.0 mA cm<sup>–2</sup> and over 200 h at 50 mA cm<sup>–2</sup>/10 mA h cm<sup>–2</sup>. Furthermore, the Zn//MnO<sub>2</sub> full cell, which has a proline-containing electrolyte, demonstrates high specific capacity (294.3 mA h g<sup>–1</sup> at 0.3 A g<sup>–1</sup>) and outstanding cycle stability with a high-capacity retention of 60% after 2000 cycles, much better than that of ZIBs with the pristine ZnSO<sub>4</sub> electrolyte. Zn//MnO<sub>2</sub> pouch cell (3.8 × 1.3 cm) also exhibits excellent cycling stability with a retention of 53.6% after 1000 cycles at a current density of 3 A g<sup>–1</sup>. This research provides a multipurpose electrolyte additive that serves as an effective reference for advancing the capability of AZIBs.</p>","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"13 20","pages":"7395–7405 7395–7405"},"PeriodicalIF":7.1,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To help address this, three bioinspired surfactants (M8Flav, M12Flav, and D8Flav) were synthesized by modifying the core structure of flavylium, a plant-based pigment, by installing secondary and tertiary alkyl amines. Hydrophobic agglomeration of fine kaolinite (<i>D</i><sub>4,3</sub>: 10 μm) particles facilitated through the application of these bioinspired surfactants was examined. Spectroscopic, microscopic, and XRD (X-ray diffraction) analyses were performed to interrogate the association of flavylium with kaolinite including the elucidation of potential interactions and mechanisms for the changes in macroscopic properties of the kaolinite aggregates. The surface hydrophobicity of kaolinite was evaluated using the Washburn capillary rise method, with enhanced hydrophobicity observed after treatment with the surfactants. Real-time in situ aggregate size measurements under a controlled shear rate were conducted using an image-derived particle size measuring technique to systematically evaluate the impact of surfactant dosage and alkyl chain configuration on aggregate size and stability. Turbidity reduction of the supernatants and gravitational sedimentation under quiescent conditions of surfactant-treated kaolinite slurries were also examined. These findings reveal the applicability of flavylium-based surfactants, positioning them as valuable tools for improving techniques in clay separation and dewatering processes.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"3 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrating nonthermal plasma with catalysts makes it possible to produce acetic acid and methanol directly from biogas consisting mainly of CO<sub>2</sub> and CH<sub>4</sub>. Among various catalysts examined, plasma-reduced Cu/Al<sub>2</sub>O<sub>3</sub> with a flower-like morphology substantially enhances methanol formation. Adding a small amount of water vapor into biogas significantly enhances methanol production under cold plasma. In situ optical emission spectroscopy, probe tests with isotope-labeled D<sub>2</sub>O and H<sub>2</sub><sup>18</sup>O, and plasma desorption analysis provide clear evidence that water not only participates in and promotes the methanol-forming reaction but also facilitates methanol desorption from the catalyst surface under plasma. Increasing the plasma discharge power, however, can dramatically switch the liquid products from methanol-dominated to acetic acid-dominated oxygenates. These novel findings provide a new strategy for the direct conversion of biogas to chemicals and fuels.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"51 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Life-cycle assessment is conducted on five lignocellulosic feedstocks along with seven pretreatment techniques to produce biosugars as an important platform intermediate for producing bioproducts. The production of electricity using lignin with and without heat integration was also incorporated. In addition, seven bioproducts are analyzed for the estimation of the GHG emissions budget, which represents the emissions available to convert, separate, and upgrade biosugars into bioproducts within the 70% emissions reduction target. Corn stover-deacetylation and dilute acid pretreatment (CS-DDA) provide the lowest GHG emissions for biosugar (0.03 kg CO<sub>2</sub> eq/kg biosugar) and thereby the highest GHG emissions budget for the case of lactic acid production (3.76 kg CO<sub>2</sub> eq/kg lactic acid).
