Bio-inspired synthesis and bio-activity of ruthenium nanoparticles from Tridax procumbens (Dagadi Pala) leaf extract.

Herein, ruthenium nanoparticles (RuNPs) were synthesized using Tridax procumbens leaf extract as a reducing and stabilizing agent. The synthesis was optimized by adjusting temperature, leaf extract concentration, and reaction time. The synthesized RuNPs were characterized using UV-visible, XRD, EDAX, FTIR spectroscopy, SEM, and TEM, revealing uniform size and morphology.

Studies on Photocatalytic and Antioxidant Efficacy of Ag-Embedded ZnO Nanocomposites.

This study focuses on the synthesis and characterization of Ag-embedded ZnO nanocomposites with varying silver (Ag) contents (1, 3, and 5 wt %) to evaluate their photocatalytic and antioxidant activities. The nanocomposites were synthesized using a sol-gel method, followed by thermal decomposition, and characterized by XRD, SEM, BET, Raman, EDS, TEM, FTIR, and UV-vis spectroscopy. The photocatalytic degradation of the rhodamine 6G (R6G) dye was tested under UV light, and its antioxidant capacity was evaluated using DPPH, ABTS, FRAP, and FIC assays.

Bio-inspired preparation of Ag NPs, rGO, and Ag/rGO nanocomposites for acoustical, antioxidant, and plant growth regulatory studies.

Acoustical properties are essential for understanding the molecular interactions in fluids, as they influence the physicochemical behavior of liquids and determine their suitability for diverse applications. This study investigated the acoustical parameters of silver nanoparticles (Ag NPs), reduced graphene oxide (rGO), and Ag/rGO nanocomposite nanofluids at varying concentrations. Ag NPs and Ag/rGO nanocomposites were synthesized via a Bos taurus indicus (BTI) metabolic waste-assisted method and characterized using advanced techniques, including XRD, TEM, Raman, DLS, zeta potential, and XPS.

Synthesis of a Ag/rGO nanocomposite using urine for nitroarene reduction and biological activity.

The elemental composition analysis reveals the presence of Ag, O and C elements.

Bos taurus (A-2) urine assisted bioactive cobalt oxide anchored ZnO: a novel nanoscale approach.

In this study, a novel synthetic method for cobalt oxide (CoO) nanoparticles using Bos taurus (A-2) urine as a reducing agent was developed. In addition to this ZnO nanorods were produced hydrothermally and a nanocomposite is formed through a solid-state reaction. The synthesized materials were characterized through modern characterization techniques such as XRD, FE-SEM with EDS, DLS, zeta potential, FT-IR, Raman spectroscopic analysis, and TGA with DSC.

Herein we have synthesized silver nanoparticles (Ag NPs) using liquid metabolic waste of Bos taurus (A-2 type) urine. Various bio-molecules present in cow urine, are effectively used to reduce silver (Ag) ions into silver nanoparticles in one step. This is bio-inspired electron transfer to Ag ion for the formation of base Ag metal and is fairly prompt and facile.
