In general, these are bulk heterojunction (BHJ) OPVs obtained through a solution process and the large-area OPV production is achieved via roll-to-roll process. In OPVs, the BHJ active layer consists of electron donor (D) and electron acceptor (A) materials blended together by dissolving them in a common organic solvent. The new low band gap non-fullerene based acceptors could be used as potential candidates for the fabrication of OPVs in combination with suitable donor polymers.

Li metal is considered as a promising anode material owing to their high capacity and low electrochemical potential. However, high reactivity of Li metal with conventional flammable liquid electrolytes easily forms Li dendrites, which may cause short-circuit and even catching fire, obstructing the wide application of Li metal batteries. Although non−/less-flammable solid electrolytes have replaced the conventional liquid electrolytes, solid-state Li metal batteries (SSLMBs) suffer from lower Li<sup>+</sup> conductivities, chemical/electrochemical incompatibilities toward Li metal, and inhomogeneous Li<sup>+</sup> flux at the interfaces. Therefore, many researchers have devoted themselves to solve these problems. For a better understanding on the current issues and recent advances, this article provides (1) a review on various solid electrolytes with high Li<sup>+</sup> conductivity and their interfacial issues in SSLMBs, and (2) recent progress in stabilization of the interface between the Li node and solid electrolytes, including an electrolyte modification (e.g., composition, additives) and introduction of an interlayer.</p>","PeriodicalId":54252,"journal":{"name":"Bulletin of the Korean Chemical Society","volume":"45 10","pages":"806-820"},"PeriodicalIF":1.7,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bkcs.12900","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142541089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To create dramatically enhanced properties and achieve unexpectedly high performances, it is necessary to incorporate multi-guests as well as control the guest-guest interaction. In the present review, we have summarized the multi-guest incorporation into LDH based on the supramolecular chemistry, which provides insights into non-covalent molecular interaction through host-guest chemistry. Four well-known intercalation methods in LDH, that is, coprecipitation, ion exchange, reconstruction, and exfoliation-reassembly, are generally applied to multi-guest intercalation. Combinative methods, in which two different intercalation approaches are combined, are also summarized.

The results consistently showed ultrasound not only enhances the excellent adsorption ability of Makgeolli lees but also accelerates the process compared to the stirring method. The Langmuir isotherm model best described the adsorption process for both methods, suggesting monolayer adsorption on the surface of Makgeolli lees, with maximum capacities of 25.13 mg/g for ultrasound at 40 kHz and 20.41 mg/g for stirring methods. Furthermore, the study showed that optimal dye removal efficiency can be achieved with ultrasound conditions at 28 kHz frequency, 125 W/L power density, and 100% ultrasound intensity.
