Aminating the surface of ZIF-8 is allowed for the conjugation of folic acid (FA). Several spectroscopic studies characterized the newly fabricated DTX-encapsulated folic acid-embedded ethylene diamine (ED) ZIF-8 nanocomposites (DTX/FA@ED-ZIF-8). It has excellent chemical stability and high drug-loading efficiency. DTX from the folic acid-embedded aminated ZIF-8 (FA@ED-ZIF-8) is three-fold more efficient under acidic pH (5.0) than in physiological settings (pH 7.4), according to in vitro drug release tests. DTX/FA@ED-ZIF-8 exhibited cytotoxicity of 76.8% in an MTT experiment conducted in A549 and H1299 cells. Cell morphological and nuclear staining were investigated in the fabricated samples to support the MTT experiments. Further, the apoptosis mode of cell death was examined using Annexin V-FITC and PI by flow cytometry. These findings indicate that FA@ED-ZIF-8 holds great potential as a drug carrier for precise dosing.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"2018 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140590756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The crystal structure, morphology and properties of the catalyst were fully characterized, and the photocatalytic performance of the catalyst was investigated by photodegradation of tetracycline hydrochloride (TCH). The crystalline structure of CdS/MgFe<sub>2</sub>O<sub>4</sub> is dominated by the cubic spinel structure of MgFe<sub>2</sub>O<sub>4</sub> with a hollow cage morphology. CdS and MgFe<sub>2</sub>O<sub>4</sub> form a tight-binding S-scheme heterostructure, which can accelerate the recombination of ineffective charge carriers and promote the separation of the effective charge carriers via the internal electric field, enabling CdS/MgFe<sub>2</sub>O<sub>4</sub> to maintain an optimal redox potential. Compared with pure CdS and MgFe<sub>2</sub>O<sub>4</sub>, CdS/MgFe<sub>2</sub>O<sub>4</sub> is more effective on degradation of TCH.

The resulting membranes were characterized regarding their morphological and structural properties, permeation performance, rejection of reference solutes and an emerging contaminant, and antifouling performance. Scanning electron microscopy, contact angle determination, Fourier transform infrared spectroscopy, and filtration tests were accomplished for that.

It is found that, unlike the existing shells or plates with spiral structures, a smaller spiral angle is of great significance to coordinate the contradiction between strength and toughness of beam materials. As the angle changes (small spiral angle), the full-field distribution of each stress component will undergo significant changes, leading to a transformation of the key stress components that dominate the damage and failure behavior. By adjusting the spiral angle, certain normal stress components inside can be reduced to improve the strength, and certain shear stress components can be increased to improve the toughness.
