The resulting nanocomposites with different TiO₂/ZnO molar ratios (90:10 and 50:50) are examined for their cytotoxic effects on colon cancer HT29 cell lines using MTT assay and flow cytometry analysis, taking into consideration the tumor selectivity, potency selectivity expression, apoptosis, necrosis, and viability of the cells. The results obtained show that the TiO₂/ZnO (50:50) nanocomposite with fine crystallite size and clustered morphology is able to significantly reduce the percentage of viable cells (28.79 ± 2%) compared to the control sample (99.4 ± 5.4%) at ultralow concentrations (≤ 10 µg/ml). Meanwhile, the late apoptosis, early apoptosis, and necrosis values of the cells are found to be 12.86 ± 1.1%, 58.25 ± 0.3%, and 0.10 ± 0.05%, respectively. Accordingly, the TiO₂/ZnO nanocomposite with high cytotoxicity can be used as an appropriate candidate for medical applications in order to effectively eliminate the colorectal cancer cells.</p></div>","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"35 8","pages":"6546 - 6560"},"PeriodicalIF":4.9,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study has the objective to observe the influence of SiO₂ and La-substitution on dielectric, magnetic in addition to structural parameters of W-type hexagonal lattice. All the samples sintered at 1000 °C have hexagonal crystal structure as observed by X-ray Diffraction patterns, in addition, the diffraction peaks of SiO₂ were not observed due to its amorphous nature. Fourier transform infrared spectroscopy provides indication of co-existence of SiO₂ along with two typical absorption bands for hexa-ferrites. The grain sizes and microstructures of all samples were observed by scanning electron microscopy that have range in nanometers. Vibrating sample magnetometer was used to determine the magnetic parameters including remanence (M_r), saturation magnetization (M_s), coercivity (H_c), anisotropy constant, magnetic moments (n_B) and anisotropy field. The measured AC susceptibility of hexagonal ferrites was observed to decrease with increasing temperature and shows a minimum value at Curie temperature (T_c). After substituting lanthanum (La) and adding SiO₂ in the samples, the reduction in T_c was also observed which might be due to the nonmagnetic nature of these constituents. The values of dielectric constant and dielectric loss were observed to decrease when frequency was increased and increased with increase in temperature following the Maxwell Wagner model. The addition of SiO₂ and La-substitution in hexaferrites increased DC resistivity to make these materials suitable for high frequency microwave devices such as dielectric resonators etc.</p></div>","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"35 6","pages":"4368 - 4382"},"PeriodicalIF":4.9,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, it is proposed to introduce oxygen vacancies and Cl ion doping to synergistically enhance the photocatalytic activity of SnO₂ degradation of MO under solar irradiation. This article describes the rapid preparation of efficient SnO₂ photocatalysts through a simple solid-phase reaction method, utilizing SnCl₂·2H₂O and hydrogen peroxide disinfectant (with H₂O₂ as the reactive substance) powder as raw materials. The physicochemical properties of the synthesized SnO₂ were investigated using powder X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Diffuse Reflectance Spectroscopy (DRS), and Photoluminescence (PL), et al. The results indicate that the mixture of SnCl₂·2H₂O and H₂O₂ reacted rapidly to form SnO₂ after simple stirring for more than ten times. XRD analysis revealed the formation of amorphous SnO₂. SEM and TEM results demonstrated that the samples consisted of numerous nanocrystalline grains with an average size of 10 nm. FT-IR results indicated the presence of abundant hydroxyl groups in the samples. XPS characterization confirmed the presence of many hydroxyl groups, oxygen vacancies and small amounts of Cl ion doping in SnO₂. DRS results showed that the synthesized SnO₂ samples exhibited good light absorption capabilities in the visible light region. Additionally, compared to the bandgap width of SnO₂ reagent, the bandgap width of the synthesized samples significantly decreased. The bandgap value of SnO₂ reagent was as high as 3.64 eV. That of the sample with the best performance obtained after optimizing the raw material ratio decreased to 2.52 eV. Its specific surface area reached 149.4 m²/g. The PL results indicate the presence of a great amount of oxygen vacancies in the synthesized SnO₂ sample. At the same time, it can suppress the recombination of photo generated electron hole pairs and improve the separation efficiency of photo generated charge carriers. The prepared SnO₂ photocatalyst demonstrated excellent photocatalytic degradation capabilities. Under simulated sunlight irradiation, the sample with the best performance can completely degrade methyl orange within 6 min.
