Achieving low-cost, high-efficiency quantification of Fe³⁺ ion concentration in unknown solutions can guide environmental management decisions and optimize water treatment processes. In this study, by leveraging the rapid, real-time detection capabilities of nanopores and the specific chemical binding affinity of tannic acid to Fe³⁺, a linear relationship between the ion current and Fe³⁺ ion concentration was established. Utilizing this linear relationship, quantification of Fe³⁺ ion concentration in unknown solutions was achieved. Furthermore, ethylenediaminetetraacetic acid disodium salt was employed to displace Fe³⁺ from the nanopores, allowing them to be restored to their initial conditions and reused for Fe³⁺ ion quantification. The reusable bioinspired nanopores remain functional over 330 days of storage. This recycling capability and the long-term stability of the nanopores contribute to a significant reduction in costs. This study provides a strategy for the quantification of unknown Fe³⁺ concentration using nanopores, with potential applications in environmental assessment, health monitoring, and so forth.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 2","pages":"Article 110428"},"PeriodicalIF":9.4,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656938","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}

However, improving the efficiency of fluorescent CDs-based ELEDs remains challenging, primarily because it is difficult to utilize triplet excitons in the electroluminescence process. Therefore, enhancing the exciton utilization efficiency of CDs during electroluminescence is crucial. Based on this, we exploited the characteristic large exciton binding energy commonly found in CDs to develop exciton-emitting CDs. These CDs facilitate the radiative recombination of excitons during electroluminescence, thereby improving the electroluminescent efficiency. By rationally selecting precursors, we developed high quantum efficiency CDs and subsequently constructed CDs-based ELEDs. The blue-light device exhibited an external quantum efficiency of over 4 %.

However, the innate low energy level of lowest unoccupied molecular orbital (LUMO) in EC makes it incompatible with lithium metal, causing uncontrolled lithium growth and low Coulombic efficiency (CE). Herein, we introduced bis(2,2,2-trifluoroethyl) carbonate (TFEC), a carbonate with a strong electron-withdrawing effect (-CF₃), which enhances the stability of EC at electrode interface by reducing ion-dipole interactions between Li⁺ and EC. As the interaction between Li and EC weakens, TFEC and more PF_6⁻ anions coordinate with Li⁺, promoting the formation of contact ion pairs (CIPs) and aggregates (AGGs), thereby increasing the inorganic composition within the solid electrolyte interphase. Additionally, the distinct solvated sheath structure favors the decomposition of fluorinated solvents and PF₆₋ anions, forming inorganic-rich electrode-electrolyte interfaces (SEI and CEI), thereby ensuring high stability for both the Li anode and high-voltage cathode. Hence, when applied in the full-cell Li||LiMn_0.8Fe_0.2PO₄, it displays consistent cycling performance, exhibiting minimal capacity decay with a retention rate of 62.5% after 800 cycles, substantially surpassing that of cells using base electrolytes (29.8%).</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 1","pages":"Article 110385"},"PeriodicalIF":9.4,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592881","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}

Undoubtedly, comprehensively investigating of the dynamic crystal structure evolutions of Na_xTMO₂ associating with Na ions extraction/intercalation and then deeply understanding of the relationships between electrochemical performances and phase structures drawing support from advanced characterization techniques are indispensable. <em>In-situ</em> high-energy X-ray diffraction (HEXRD), a powerful technology to distinguish the crystal structure of electrode materials, has been widely used to identify the phase evolutions of Na_xTMO₂ and then profoundly revealed the electrochemical reaction processes. In this review, we begin with the descriptions of synchrotron characterization techniques and then present the advantages of synchrotron X-ray diffraction (XRD) over conventional XRD in detail. The optimizations of structural stability and electrochemical properties for P2-, O3-, and P2/O3-type Na_xTMO₂ cathodes through single/dual-site substitution, high-entropy design, phase composition regulation, and surface engineering are summarized. The dynamic crystal structure evolutions of Na_xTMO₂ polytypes during Na ion extraction/intercalation as well as corresponding structural enhancement mechanisms characterizing by means of HEXRD are concluded. The interior relationships between structure/component of Na_xTMO₂ polytypes and their electrochemical properties are discussed. Finally, we look forward the research directions and issues in the route to improve the electrochemical properties of Na_xTMO₂ cathodes for SIBs in the future and the combined utilizations of multiple characterization techniques.
