SEM observed the formation of well-shaped particles, and the presence of Mg, Ca, Ba, Nb, and O with the proper compositions was confirmed by EDS. TEM proved the polycrystalline nature of sample BaNb2O6. The metal oxides MgNb2O6, CaNb2O6, and BaNb2O6 showed band gaps of 2.19 eV, 2.13 eV, and 0.90 eV, respectively. The calculations of the total and partial density of states were carried out to examine the effects of atomic orbitals on the formation of bands. The BoltzTraP algorithm within the Wien2k code was used to study the novel transport properties. The productive values of the figure of merit suggest that the studied materials are suitable for thermoelectric applications.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"2 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140630295","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}

For the glass transition, two linear regions with different apparent activation energies (Ea,g) are distinguished by a critical heating rate of 2000 K/s: Ea,g decreases from 208.7 to 67.3 kJ/mol with the increase of heating rate. During the crystallization, the nucleation rate and crystal growth rate between Tg and Tm are calculated. According to their dependence on temperature, the contact angle for the nucleation of Ce crystals is estimated at 11–14 degrees. For the crystal growth, a maximum crystal growth rate of 0.03 m/s is found at 0.97 Tm. Moreover, the breakdown of the Stokes–Einstein equation in the deeply undercooled melt is observed, where the diffusivity is related to viscosity by D ∝ η−0.865.<h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"127 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140615233","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}

Silica coating was realized by the sol–gel process carried out in a vacuum evaporator at 60–70 °C. The most uniform and thin layer of silica coating was obtained by the Stöber method based on the hydrolysis of tetraethyl orthosilicate (TEOS) catalysed by an ammonia solution. Effective TiO2 coating was obtained by the immersion of EPS in the titania aqueous suspension and evaporation of water in a vacuum evaporator. Heating of EPS spheres coated by SiO2, TiO2 or SiO2–TiO2 at the temperatures of 120–140 °C resulted in a shrinkage of their volume. For the thick layer coating, a strong corrugation of EPS surface was observed.

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.<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/MgFe2O4 is dominated by the cubic spinel structure of MgFe2O4 with a hollow cage morphology. CdS and MgFe2O4 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/MgFe2O4 to maintain an optimal redox potential. Compared with pure CdS and MgFe2O4, CdS/MgFe2O4 is more effective on degradation of TCH. Moreover, magnetic separation, recovery, and recycling of the composite catalyst can be achieved without secondary contamination by using the magnetic properties of the CdS/MgFe2O4. <h3>Graphical abstract</h3> <img alt=\"\" src=\"https://static-content.springer.com/image/MediaObjects/43578_2024_1331_Figa_HTML.png\"/> ","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"59 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140590867","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}

In this study, membranes were produced using the phase inversion technique using polysulfone, polyvinylpyrrolidone, and Cyrene—a recently developed solvent, whose physicochemical profile is comparable to conventional ones, but is biodegradable, non-toxic, and eco-friendly. 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 was possible to use Cyrene to produce polysulfone-based membranes, in which the one with 5% polyvinylpyrrolidone was the membrane with the highest permeability. Conversely, the membrane without polyvinylpyrrolidone and with a 30-min heat treatment achieved 73% rejection of the emerging contaminant evaluated.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"13 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140316658","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}

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. These results will provide optimization strategies for the mechanical design of beam.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000The beam with an internal structure of spiral laminated fiber has been designed.
