The crude leaf extract of Phragmanthera macrosolen L. has been utilized for the first time as an effective reducing, capping and stabilizing agent to synthesize silver oxide nanoparticles (AgO NPs) through a green approach. The prepared AgO NPs were analyzed by scanning electron-microscopy (SEM), High Resolution Transmission electron microscope (HR-TEM), X-ray diffractions (XRD), Fourier transforms infrared (FTIR) spectroscopy, energy dispersive spectroscopy (EDS), and Ultra-violet visible spectrometry (UV-Vis).

- Nanotechnology is increasingly vital for industries focusing on human well-being, leading to the synthesis of environmentally friendly SnO nanoparticles using Croton macrostachyus leaf extract.
- Characterization techniques confirmed a shift in UV absorbance to the visible spectrum, resulting in varied energy band gaps that enhance photocatalytic activity.
- The study demonstrates that these green-synthesized nanoparticles can effectively degrade common pollutants like rhodamine B and methylene blue under visible light, showcasing their potential for low-energy environmental remediation.
Article Synopsis
- The research focuses on using waste Ramie Root as a powdered filler in reinforced polyester composites, creating plates with varying percentages of the root and unsaturated polyester resin through a compression molding technique.
- The optimal mechanical properties were found in the composite with a 30:70 weight ratio of Ramie Root to polyester resin, showing improvements in glass transition temperature and bonding strength, which enhance dynamic mechanical properties.
- Thermo-gravimetric analysis indicated that incorporating Ramie Root powder raised the thermal deterioration peak from 370 °C to 418 °C, and the composites displayed high tensile strength and bending stiffness, making them suitable for light-load applications.
Drug repositioning is a method of using authorized drugs for other unusually complex diseases. Compared to new drug development, this method is fast, low in cost, and effective. Through the use of outstanding bioinformatics tools, such as computer-aided drug design (CADD), computer strategies play a vital role in the re-transformation of drugs.
