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 multi-guest incorporation, despite the difficulty involved in its synthesis design, could provide fine-tuned and enhanced properties that are useful for a variety of applications.</p>","PeriodicalId":54252,"journal":{"name":"Bulletin of the Korean Chemical Society","volume":"45 9","pages":"724-737"},"PeriodicalIF":1.7,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142313263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By incorporating ultrasound, the effects of contact time, Makgeolli lees dosage, initial AO7 dye concentration, and initial pH of the dye solution were investigated and comprehensively compared with the same experiment using the stirring method. 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.

Elemental mapping analysis confirmed the Ag deposition on the AuNR surface, with Ag content measured at 26.7% for AuNR@Ag<sub>26.7</sub> with a 1-day incubation period and 34.8% for AuNR@Ag<sub>34.8</sub> with a 2-day incubation period.

A custom scoring function was employed during docking to identify an improved initial binding pose, and the linear interaction energy method with an optimized coefficient was used for binding affinity estimation. The protocol was validated with an external data set and applied to modafinil and its derivatives to rank their binding affinities to adenosine A2A receptors (ADORA2A) as a case study.
