However, the potential toxicity of metallic substances presents an obvious drawback. In this paper, magneto-optical bifunctional Fe₃O₄/Gd₂O₃:Tb³⁺@SiOx nanocomposites were synthesized via co-precipitation and polyol method. The biocompatibility and dispersibility of Fe₃O₄/Gd₂O₃:Tb³⁺ were improved by covering the outer side with a layer of SiOx. The effects of various synthesis temperatures on the properties of the composites were investigated. It was found that with the increase of synthesis temperature, the average particle size of Fe₃O₄/Gd₂O₃:Tb³⁺@SiOx crystal increased from 15 to 23 nm and the saturation magnetization decreased from 13.734 to 10.623 emu/g. Higher luminescence and magnetic intensity are observed in the nanocomposites synthesized at 25 °C due to the enhanced crystallinity and size uniformity. Finally, in vitro cytotoxicity and in vivo MR images in SD mice demonstrated the excellent biocompatibility and high-resolution MR imaging of Fe₃O₄/Gd₂O₃:Tb³⁺@SiOx.</div></div>","PeriodicalId":18233,"journal":{"name":"Materials Science and Engineering: B","volume":"316 ","pages":"Article 118162"},"PeriodicalIF":3.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 paper, the relevant data obtained by machine learning are screened and combined with the development concept of high efficiency and environmental protection; the lead-free Cs₂NaB’Cl₆ (B’ = In, Cr, Y, and Tb double-halide perovskite) is selected as the research object from the perspective of bandgap and energy. The structure and optoelectronic properties of the system are investigated using the first-principles density functional theory method. In terms of electrical performance, Cs₂NaInCl₆ and Cs₂NaCrCl₆ can be used for wide-bandgap perovskite batteries because of their bandgaps of 2.81 and 2.86 eV, while Cs₂NaYCl₆ and Cs₂NaTbCl₆ have bandgaps of 5.05 and 5.19 eV, which can be used for detectors. In terms of optical performance, the reflectivity of Cs₂NaB’Cl₆ (B’ = In, Cr, Y, Tb)-halide perovskite is all less than 11 %, with low reflection loss and no metallic luster, so the material system has high transmittance and can be used for research and development of high-transmittance applications. CsNaCrCl₆ shows a significant absorption peak in the visible light range, and the three materials show a significant absorption peak in the ultraviolet region. It is found that Cs₂NaCrCl₆ has broad application prospects in the field of tandem solar photovoltaic power generation and photovoltaic building integration because of its appropriate bandgap value, low reflectivity, and excellent light absorption performance.

Diamond wire saw technology has shown great potential in cutting ZTA ceramics. This paper conducted experiments on diamond wire sawing of ZTA ceramics to analyze the effects of wire speed and feed speed on surface morphology, surface roughness, and the peak-to-valley (PV) value of saw marks. An image processing method was used to investigate the variation of the number and area of these depressions with changing of processing parameters. It was shown that diamond wire saw machining of ZTA ceramics resulted in material removal mainly by brittle fracture, and that the processing parameters had a significant effect on surface quality. The surface roughness improved as the wire speed increases from 1000 m/min to 1400 m/min and the feed speed decreases from 0.3 mm/min to 0.1 mm/min, while the PV increased with both. Large depressions were commonly observed on the sawn surface, with both their number and area increasing as wire speed decreased and feed speed increased. As the ratio of feed speed to wire speed increased, the number and area of depressions generally showed an increasing trend, the variation was influenced by multiple factors, not just the speed ratio.

Structural, morphology, and optical properties were studied using advanced instruments. The formation of a monoclinic WO₃ phase in all synthesized samples was confirmed through X-ray diffraction (XRD) analysis. Optical studies revealed that Cu-doped WO₃ nanoparticles exhibit a narrowed bandgap energy, facilitating the generation of free radicals capable of effectively degrading textile effluent dye molecules.
