Abstract Dodonea viscosa -zinc oxide (DV-ZnO) nanocomposite was synthesized and characterized using Fourier transform infrared (FTIR), thermal gravimetric method (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). The most abundant compounds in the plant extract were explored gas chromatography-mass spectrometry (GC-MS). FTIR indicated existence of different functional groups, XRD showed that has hexagonal wurtzite shape ZnO nanoparticles, SEM-EDS a size 50 nm, elemental analysis depicts elements extract, which confirms, along with TGA results, formation DV-ZnO nanocomposite. synergistic effect examined for anticorrosion capabilities gravimetric, electrochemical, surface methods. Both exhibited corrosion inhibition abilities. However, incorporation increased efficiency by 20 %. Weight loss electrochemical methods concluded an 80 % is due to adsorption inhibitor on carbon steel surface, verified photoelectron (SEM). found follow both Langmuir Temkin isotherms. Surface examination atomic force (AFM) roughness decreased from sample submerged uninhibited medium (Sa = 121.20 nm) when adding 22.95 DV 54.73 nm).

In recent years, the world scientific community has shown increasing interest in rare earth metals general and their nanoparticles particular. Medicine pharmaceuticals are no exception this matter. review, we have considered main opportunities potential applications of metal (gadolinium, europium, ytterbium, holmium, lutetium, dysprosium, erbium, terbium, thulium, scandium, yttrium, lanthanum, neodymium, promethium, samarium, praseodymium, cerium) biomedicine, with data ranging from single reports effects found vitro to numerous independent vivo studies, as well a number challenges for wider application. The areas application metals, including future, diagnosis treatment malignant neoplasms, therapy infections, use antioxidant regenerative properties nanoparticles. These determined both by themselves need search new approaches solve urgent biomedical public health problems. Oxide forms lanthanides most often used biomedicine due greatest biocompatibility nanoscale size, providing penetration through biological membranes. However, existing contradictory or insufficient on acute chronic toxicity still make widespread difficult. There various modification methods (addition excipients, creation nanocomposites, changing morphology particles) that can reduce these effects. At same time, despite some representatives clinical practice, further studies establish full range pharmacological toxic effects, modify remain relevant.

The application of nanotechnology offers a promising solution to improve fertilizer utilization efficiency by mitigating the losses and volatilization conventional fertilizers, contributing sustainable agriculture. In this study, core–shell nanocarbon-based slow-release foliar (CN@mSiO2-NH2@Urea@PDA) was synthesized using nanocarbon (CN) as core, amino-functionalized mesoporous silica (mSiO2-NH2) shell, polydopamine (PDA) coating layer. BET analysis revealed 3.5-fold 1.9-fold reduction in material porosity after PDA encapsulation, confirming successful synthesis. controlled-release performance enhanced, with 24% decrease release rate prolonged nutrient delivery duration. Hydrophobicity tests demonstrated 20° increase contact angle, indicating improved adhesion. Seed germination assays validated biosafety, while field trials showed 69.94% choy sum (Brassica rapa) yield, 21.64% higher nitrogen efficiency, 22.21% reduced loss. increased plant use 18.37%. These findings highlight potential CN@mSiO2-NH2@Urea@PDA an advanced fertilizer, providing strategic approach promote nanomaterial applications agriculture enhance acceptance functional fertilizers among farmers.

There is a growing need for an economical and efficient method capable of removing heavy metals from residual water. The current contribution aimed to evaluate the capacity onion peel, abundant agroindustrial waste product, remove divalent cobalt (Co2+) aqueous solutions. Onion peel was submitted proximal chemical analysis, various operational factors involved in biosorption were tested. most suitable temperature (30 °C), pH (7.0), biosorbent particle size (300–800 µm) found. With initial Co2+ concentration 380 mg L−1, maximum removal 59.88 g−1 120 min. pseudo-second order Langmuir models provided best fit experimental kinetics equilibrium biosorption, respectively. thermodynamic study evidenced exothermic, non-spontaneous, favorable reaction (ΔH0 = −5.78 kJ mol−1; ΔS0 −21.13 J mol−1 K−1), suggesting formation stable bonds biosorbent-Co2+ complex. carbonyl hydroxyl groups apparently play fundamental role removal, electrostatic attraction, ion exchange, chemisorption are principal mechanisms. Thus, by has potential as economical, eco-friendly, efficient, sustainable treatment wastewater.
