A one-pot hydrothermal method was employed to synthesize Co-doped BiVO₄ nanostructures at varying dopant concentrations (5 % and 10 %) and to investigate their morphologies and structural characteristics using various analytical techniques. XRD patterns revealed the presence of monoclinic and tetragonal phases, resulting from the synergistic effects of Co-doping and percentage tuning during the synthesis process. FTIR spectra identified the metal oxygen vibrational modes. UV-Vis analysis revealed tunable optical band gaps, indicating improved electronic properties resulting from Co-doping. An electrochemical study, including cyclic voltammetry (CV) and Galvanostatic charge-discharge (GCD), of the BiVO₄ material revealed an impressive enhancement in supercapacitor performance following Co-doping. The 10 % Co-doped BiVO₄ electrode exhibited a specific capacitance (Cs) of 211.00 F/g under a 10 mV/s CV scan rate, which significantly outperformed that of the 5 % Co-doped (170.2 F/g) and undoped (34.00 F/g) counterparts. Although GCD investigations revealed that 5 % Co-doping yielded the longest discharge times at low current densities (∼70 s for 5 % Co compared to ∼47 s for 10 % Co at 0.5 mA/g), both doped samples significantly outperformed the undoped BiVO₄. The results show the significant impact of Co-doping on the structural and electrochemical properties of BiVO₄, establishing Co-doped BiVO₄ as an excellent candidate for energy storage devices.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"43 ","pages":"Article 101510"},"PeriodicalIF":5.45,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrochemical treatment was conducted under different potentials (10 V and 20 V) and durations (1 h and 2 h). Following anodization, samples underwent thermal treatment to transform the initially amorphous NT layers into crystalline phases. X-ray diffraction (XRD) confirmed the amorphous nature of the as-anodized surfaces, which crystallized into anatase and rutile phases after heating. Structural and microstructural features were analyzed via XRD, scanning electron microscopy (SEM), and atomic force microscopy (AFM), which were used to assess surface roughness, NT length, and diameter. Wettability and surface free energy were evaluated using the sessile drop contact angle method. This study investigates how anodization parameters and alloy composition affect the crystallinity, morphology, and surface properties of TiO₂ NTs. TN15 samples exhibited α-phase Ti with a mix of anatase and rutile, while TN40 samples showed dominant β-phase Ti and greater rutile content. NTs on TN15 were more uniformly aligned, whereas TN40 formed NTs in isolated domains. Longer anodization times and higher voltages increased NT length and diameter.

However, as it is shown here, floral models continue to be predominantly utilized within resource-limited research environments and remain largely underrepresented in mainstream biomedical investigations conducted by well-funded institutions in the developed world. The ability to delay the senescence of Orange Jubilee wildflowers was tested here on three types of nanoparticles: selenite-doped hydroxyapatite (HAp), citrate-stabilized HAp, and superparamagnetic iron oxide. Integration of selenite into the HAp crystal lattice produced a mild increase in the senescence rate relative to HAp. Iron oxide nanoparticles produced nil effects on senescence when added as powders and marginal effects when delivered as colloids. Colloidal stabilization of HAp nanoparticles with citrates significantly extended the flower viability, which was due to the ability of citrates to: (i) disperse the nanoparticles and thus facilitate their penetration into herbal tissues via their upward transfer along the xylem, and (ii) impart moderate acidity to the medium and thus intrinsically inhibit the growth of bacteria that block the flower stem and obstruct the water uptake. Orange Jubilee flowers prove as a solid, albeit pleiotropic model for assessing the biological barrier permeation and antibacterial activity of colloids and fine powders.

In our molecular dynamics experiments we simulated CM in a bimetallic Cu-Ag nanolayer using the embedded atom method. In particular, the kinetic dependencies of the potential term into the specific (per atom) internal energy, the sample sizes, the radial distribution function, and the volume concentration of both kinds of atoms were found to reveal and analyze sequential stages of CM. A special emphasis is made on employing the fractal dimension as an important and new descriptor of CM. A concept has been developed of the dynamic evaluation of the fractal dimension of instantaneous images of atomic configurations at all the stages of CM. A conclusion is made that kinetics of the fractal dimension and information entropy adequately reflects the growth of the conventional thermodynamic entropy during the CM process. The vacancy pore formation at the earliest stage of CM (before nucleation and growth of a liquid phase) was discovered thanks to employing, the Connolly algorithm used before to construct Connolly surfaces in organic materials only. Thus, for the first time, we observed a manifestation of the Kirkendall effect in the course of CM at the nanoscale.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"43 ","pages":"Article 101496"},"PeriodicalIF":5.45,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

KFS is essential for plant metabolism and stress tolerance, with FeS₂ known for its role in improving soil micronutrient availability and sulfur content. A simple green synthesis approach was used to produce KFS NPs with <em>Arachis hypogaea</em> peel as a fuel. The structural and morphological properties of the NFs were confirmed using advanced techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), as well as elemental analysis, EDAX and Fourier transform infrared spectroscopy (FT-IR). XRD patterns are strongly aligned with the standard JCPDS No. 71–53 of FeS_2, signifying that they belong to the cubic pyrite phase with all the sides of the crystal being equal to 5.4281 Å, associated with the Pa-3 space group.
