The prepared oxides were characterized physicochemically by the FTIR, P-XRD, and SEM techniques to study their formation, structure, and morphology. The prepared oxide electrodes were tested for their electrochemical performance for oxygen evolution reaction by the cyclic voltammetry and the Tafel polarization techniques. The voltammograms of each oxide electrode showed two redox peaks, one cathodic peak (E<sub>pa</sub> = 170–245 mV) and another anodic peak (E<sub>pa</sub> = 541–603 mV). The electrocatalytic performance of oxide electrodes in 1 M KOH at 25°C was investigated using the Tafel polarization method. Doping nickel in the oxide matrix greatly enhanced the electrocatalytic activity for the oxygen evolution reaction (OER). The most active electrode in the current study was the 0.8-mol nickel substituted oxide electrode, which demonstrated a Tafel slope (b) of 88 mVdec<sup>−1</sup> and a current density (j) of 50 mA cm<sup>−2</sup> at 331 mV oxygen over potential.

Our key finding of comparative analysis highlights that gold nanoparticles yield promising outcomes even on historically challenging porous substrates due to their affinity for sweat and amino acids. Conversely, zinc oxide and titanium dioxide exhibit superior fluorescence-based contrast on non-porous surfaces such as glass and plastics, as well as some porous surfaces. The rest of the nanoparticles were able to achieve their success on porous and non-porous surfaces with some limitations. We also outline diverse methods employed by various researchers, including dusting, brushing, spraying, and fluorescence imaging, while emphasising the role of substrate texture and the functionalization of nanoparticles.

In response, this study presents the insecticidal potential of graphene materials in the form of nanopowders as new chemical and resistance free grain protectants. The influence of the grain types such as rice, maize, and wheat and graphene nanopowder characteristics on insectidicial efficacy against common grain insects was evaluated against three most destructive grain insects including: the rice weevil, <i>Sitophilus oryzae</i> (L.) (Coleoptera; Curculionidae), the maize weevil, <i>Sitophilus zeamais</i> Motschulsky (Coleoptera; Curculionidae), and the red flour beetle, <i>Tribolium castaneum</i> Herbst (Coleoptera; Tenebrionidae). Three industrially produced graphene nanopowders with distinct physicochemical properties (particle size, surface chemistry, hydrophobicity) were used at two dosage rates (500 and 1000 ppm). Mortality of insects was assessed after 7, 14, and 21 days of exposure, and progeny production was evaluated after 65 days. The results indicated that <i>S. oryzae</i> exhibited the highest susceptibility among the tested species, with rice grains experiencing the most significant insect mortality across all graphene concentrations (500 and 1000 ppm). Significant reductions in progeny with minor produced insects were observed, especially in maize, highlighting the long-term protective effects of graphene nanopowders. The insectidicial mode of action is attributed to a physical mechanism involving the adhesion of graphene particles to insect bodies, obstructing respiration and disrupting the cuticle. These findings suggest that graphene nanopowders, due to their unique structural, chemical and interfacial properties, have a strong potential to be used as new grain protectants, providing unique physical mode of action.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04359-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145240452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 recent years, there has been an exponential growth in exosome-related research because of their excellent biocompatibility ability, loading capacity and cellular internalization, making exosome to be one of the hotspots and a promising strategy in AD therapy research.

Ternary hybrid nanofluids have evolved to offer improved thermal efficiency compared to standard nanofluids. The current study involves a ternary hybrid nanofluid of copper oxide (CuO), titanium dioxide (TiO<sub>2</sub>), and silver (Ag) nanoparticles suspended in a base fluid of water-ethylene glycol (50–50%) (H<sub>2</sub>O–C<sub>2</sub>H<sub>6</sub>O<sub>2</sub>) to enhance thermal efficiency. This comprehensive analysis aims to provide insights into the heat transfer behaviour of a ternary hybrid nanofluid flow through a porous medium, considering the magnetic field effects in the momentum equation, exothermic/endothermic (Thermochemical) reactions in the energy equation, and activation energy in the concentration equation, respectively, on a rotating stretching sheet. Partial differential equations (PDEs) govern the flow problem. PDEs are converted to Ordinary differential equations (ODEs) using a suitable similarity transformation to aid solution. The linearised equations are solved numerically using MATLAB’s “bvp4c” boundary value problem solver. Variations in the velocity, temperature and concentration profiles due to various parameters are presented graphically. The results show that increasing M and Fr values increases <span>(theta )</span> profile by 1.2% and 0.85% respectively. Whereas the overall increase in the heat transfer is 6.65% and mass transfer is 1.86%, making this a substantial contribution to our work.
