Cold plasma, green synthesis, and co-precipitation methods were employed to control the ZnO/ZnFe₂O₄ phase ratios, crystallite size, and oxygen vacancy density. Comprehensive characterization using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS), ultraviolet–visible spectroscopy (UV–Vis), Raman spectroscopy, and multivariate statistical analyses (principal component analysis (PCA), 3D-PCA, Pearson correlation, and hierarchical cluster analysis (HCA)) established clear synthesis–structure–function relationships. The cold plasma route yielded the most ZnO-rich and highly crystalline heterostructure (59% ZnO, 38 nm crystallites, 75.8% crystallinity), which exhibited superior antioxidant activity (FRAP: 327.8 µmol AAE/g; TAC: 401.2 µmol AAE/g; β-carotene/linoleic acid bleaching IC₅₀: 0.171 mg/mL) and the strongest inhibition of <i>Staphylococcus aureus</i> and <i>Pseudomonas aeruginosa</i> biofilms. The co-precipitation-derived sample achieved the highest photocatalytic degradation of Rose Bengal (87.4% in 120 min), followed by the cold plasma sample (84.3%) and the green-synthesized sample (81.2%), with the superior performance of the co-precipitated catalyst attributed to its higher grain-boundary density and greater surface active site availability. In contrast, the ferrite-rich co-precipitated sample (57% ZnFe₂O₄) demonstrated superior adsorption and removal of cationic Methylene Blue (88.4%), followed by the green-synthesized sample (87.5%), while the cold plasma sample achieved (82.5%). Statistical modeling revealed that ZnO abundance and crystallite size strongly correlate with biological performance (r &gt; 0.99), while photocatalytic efficiency is governed by dye-specific surface interactions. These findings highlight a synthesis-dependent divergence between biological redox activity and dye-selective photocatalysis, providing a rational design framework for advanced multifunctional oxide-based nanomaterials.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"120 2","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10971-026-07189-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, methyl orange (MO)-doped 45S5 silicate–phosphate glasses containing (0.02, 0.04, 0.06, and 0.08 wt. %) MO were synthesized via a low-temperature sol–gel route, and the effects of MO incorporation on their structural, morphological, compositional, and optical properties were systematically investigated. X-ray diffraction revealed variations in the relative amorphous and crystalline contributions of the glass matrix, accompanied by the appearance of a calcite (CaCO₃) phase in the MO-containing samples. FTIR spectroscopy revealed changes in the vibrational features of the silicate–phosphate network following MO incorporation, while SEM-EDX and elemental mapping provided complementary evidence for microstructural densification and the presence and spatial distribution of MO-associated elements within the analyzed regions. UV–Vis diffuse reflectance spectroscopy combined with the Kubelka–Munk approach revealed pronounced changes in the optical response of the doped samples. The optical band-gap energies estimated using Tauc analysis decreased from 5.86 to 4.82 eV for allowed direct transitions and from 5.54 to 4.18 eV for allowed indirect transitions with increasing MO concentration. The optical conductivity also exhibited systematic changes following MO incorporation. Photoluminescence measurements showed a gradual decrease in emission intensity with increasing MO concentration, while the main emission features remained at comparable spectral positions.

In this work, magnesium oxide (MgO) nanoparticles were synthesized via a green route using <i>Mangifera indica</i> peel extract and subsequently deposited onto Ti6Al4V substrates by electrophoretic deposition (EPD) to explore their potential as antibacterial coatings. Following thermal analysis, the synthesized powders were calcined at 500 °C (HT500) and 700 °C (HT700). XRD and Rietveld refinement confirmed the formation of crystalline cubic MgO, with phase purities of 82.01 wt.% and 98.72 wt.% for HT500 and HT700, respectively. Crystallite size increased with calcination temperature, reaching approximately 62 nm for HT700 according to Rietveld refinement. SEM analysis revealed a transition from highly agglomerated particles to more defined polyhedral morphologies at higher calcination temperatures. The antibacterial activity of HT700 nanoparticles was evaluated against <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>. A concentration-dependent reduction in bacterial viability was observed, with significant inhibition of <i>E. coli</i> from 3 mg/mL and <i>S. aureus</i> from 6 mg/mL onwards. The antibacterial effect was accompanied by an increase in culture medium pH, reaching values close to 10 at the highest nanoparticle concentrations. EPD successfully produced homogeneous MgO coatings on Ti6Al4V substrates, which showed a reduction in bacterial viability, particularly against <i>S. aureus</i>.

CZTSSe absorbers were fabricated using precursor solutions with and without MPA under different solvent environments (MOE: DMF solvent ratios of 50:50 and 25:75), followed by selenization. GIXRD and Raman analyses confirmed the dominant formation of kesterite CZTSSe absorbers, while the MPA-treated samples exhibited larger crystallite sizes, reduced microstrain, and improved local structural ordering. FESEM and AFM observations revealed that MPA incorporation promoted grain coalescence, reduced surface roughness, and produced more compact absorber layers. Conductive AFM further revealed that the MPA-treated films exhibited a more spatially connected current distribution, indicating improved local electrical connectivity and reduced defect-assisted charge transport. Hall effect measurements further showed an increase in carrier concentration from ~10¹⁴ to ~10¹⁹cm⁻³ and a corresponding reduction in resistivity, confirming improved charge transport after MPA incorporation. However, DMF-rich systems exhibited smaller crystallite sizes and greater electrical inhomogeneity than films prepared using balanced solvent compositions, suggesting that an excessive DMF fraction limits long-range crystallite development through changes in precursor coordination and film formation. Among all the samples, M5, prepared with MPA under balanced solvent conditions (MOE: DMF = 50:50), exhibited the most favorable combination of crystallinity, compact morphology, and electrical performance.
