The sol-gel technique was employed to synthesise Sm3+-doped Cu-MgFe2O4 spinel ferrites, confirming the samples’ cubic spinel structure. X-ray diffraction analysis confirmed a single-phase cubic spinel structure, with Rietveld refinement indicating that Sm3 + ions occupy octahedral sites, leading to lattice deformation and improved crystallinity. With increasing Sm3 + concentration, both grain and particle sizes decreased. The mechanical parameter indicated that the surface area varied between 29.645 and 31.606 (m2/g). The SEM and TEM images showed that each particle had a spherical morphology. FESEM illustrations indicated grain sizes between 58.16 and 62.15 nm. The compositional verification was conducted using EDS analysis, which confirmed the presence of components in appropriate proportions. UV-vis analysis identified a direct band gap ranging from 1.85 to 1.67 eV, suggesting semiconducting properties of the materials. Sm3 + doping enhanced the dielectric constant through its effects on space charge polarisation and charge hopping, with conductivity following a Debye-type relaxation mechanism. DC electrical conductivity studies further confirmed the semiconducting nature of these materials. Magnetic measurements were conducted using VSM, revealing that the saturation magnetisation decreased from 26.826 to 22.542 emu/g upon the introduction of the Sm3+ ions. The MR/MS ratio for all ferrites is below 0.5, confirming their ferromagnetic isotropy and their functioning as magnetic semiconductors.
The current study used the citrate sol-gel auto-combustion method to fabricate Yb3+-doped Cu0.7Mg0.3Fe2O4 (Cu0.7Mg0.3Fe2-xYbxO4; x = 0.00, 0.004, 0.008, 0.012, 0.016, 0.020) ferrite nanoparticles. The P-XRD observations confirmed the presence of nano-spinel crystallites with sizes between 35.84 nm and 37.92 nm. According to FE-SEM and TEM data, Yb3+ doping improved grain dispersion and slightly increased grain size. All the FE-SEM micrographs showed spherical, well-structured, polycrystalline particles believed to consist of multiple grains. FT-IR measurements identify the two ferrite characteristic bands, upsilon 1 (similar to 386-401 cm(-1)) and upsilon(2) (similar to 510-574 cm(-1)). Additional Yb3+ doping decreased the optical band gap from 3.35 to 2.81 eV. As the temperature increases, the DC resistivity decreases in both the ferromagnetic and paramagnetic regions. CMYF nano-ferrites exhibit standard dielectric behaviour in terms of dielectric constant, dielectric loss, and AC conductivity. A lower loss tangent in Yb-doped Cu-Mg nano-ferrite materials is beneficial for deflection coupling and high-frequency applications. Coercivity (Hc) increased, and saturation magnetisation (Ms) decreased in proportion to the addition of Rare-Earth Yb3+ ions. The highest coercivity (204.441 Oe) and the lowest saturation magnetisation (21.799 emu/g) of CMYF-5 make it suitable for high-frequency, microwave, and magnetic recording applications, as well as magnetoelectric composite applications, where magnetic stability and reduced loss are essential.
Wastewater treatment is a crucial global concern with substantial environmental and public health ramifications. The degradation of carcinogenic impurities from industrial and domestic effluents has become challenging with conventional methods. Titanium dioxide-carbon dots (TiO2@CDs) nanocomposite was synthesized from bulk TiO2 employing Ananas comosus as carbon source via simple ultrasonication for photocatalytic degradation of pollutants. The present work highlights the tailored bandgap of TiO2@CDs specifically tuned to 2.31 eV, making it suitable for utilizing visible light radiation. The structural, electrochemical and optical characteristics of the synthesized TiO2@CDs nanocomposite were characterised using Ultraviolet-visible spectroscopy, X-ray photoelectron spectroscopy, Scanning electron microscopy, Fourier-transform infrared, and X-ray diffraction. Results showed that TiO2@CDs nanocomposite achieved 81% photocatalytic degradation of MB dye in 120 mins. Thus, this study opens a new possibility for developing effective semiconductor nanoparticles for applicability in photo-catalysis.
Nano particles prepared via biological extracts show diverse properties, leading to wide range of applicability in many areas. This study provides the comparative properties of ZnO nanoparticles (ZnO NPs) synthesised using extracts of Honey and Nigella sativa seeds, by the sol-gel route. The XRD revealed a hexagonal wurtzite structure, and the crystallite size for Nigella sativa seed-based ZnO (B) was 32.25 nm, whereas honey-based ZnO (H) was 25.31 nm. The Zn-O bond stretching and other vibrations were confirmed through FTIR spectra. The absorption edge and optical properties were verified by UV-visible spectroscopy and absorption peaks were observed at 350 nm for (ZnO (H)) and 352 nm for (ZnO (B)). Raman spectra exhibited broadened phonon bands for ZnO (H), probably due to phonon confinement, and for ZnO (B), a blue shift was observed due to organic residues in Nigella sativa seeds. SEM-EDX revealed the spherical morphology for both biological extracts-based nanoparticles, and the exclusive presence of Zn and O elements attests to the purity of the samples. The synthesised ZnO nanoparticles were applied for latent fingerprint development using the dusting method. ZnO (H) NPs showed proficient visibility of fingerprints and ridge characteristics on different surfaces. Antimicrobial activity was done through the agar well diffusion method on ZnO NPs for the gram-positive, gram-negative bacterial strains and fungal strains. The ZnO (H) sample showed a maximum inhibition zone for Minimum Inhibition Concentration (MIC) of 0.5
Kalki Cheruvu, a freshwater ecosystem, was investigated to understand the relationship between phytoplankton diversity and physico‑chemical parameters. Phytoplankton distribution is closely regulated by hydrochemical and physical variables, which directly influence population dynamics and community composition. Monthly sampling was conducted from 2023 TO 2024, following APHA (2005)[1] protocols, to analyse parameters such as temperature, pH, carbonates, bicarbonates, total hardness, chlorides, phosphates, nitrates, nitrites, silicates, dissolved oxygen, biological oxygen demand, and organic matter. Four algal groups were identified: Chlorophyceae, Cyanophyceae, Bacillariophyceae, and Euglenophyceae. Among these, Chlorophyceae was the most dominant, followed by Cyanophyceae, Bacillariophyceae, and Euglenophyceae, reflecting the ecological status of the lake. The study revealed significant seasonal variation in water quality parameters, though most values remained within permissible limits, indicating good water quality. Overall, the findings suggest that Kalki Cheruvu supports a healthy phytoplankton community and provides water suitable for drinking purposes. This work highlights the importance of continuous monitoring of freshwater ecosystems to ensure ecological balance and sustainable utilisation
