In this paper, a novel ternary nanocomposite namely reduced graphene oxide/hydroxyapatite/silver (rGO/HAP/Ag) was prepared by a simple hydrothermal method using graphene oxide nanosheets, Ca(NO3)2, (NH4)2HPO4, and AgNO3 as starting materials. The as-prepared nanocomposite was characterized by using various photophysical techniques including Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, transmission […]
Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transformed Infrared Spectroscopy and Scanning Electron Microscopy. The formation of AuNPs and […]
The novel approach has been carried for the green synthesis of silver nanoparticles using leaf extract of Cinnamomum tamala and silver nitrate solution. The optimal condition for synthesizing Ag-NPs was obtained by varying the leaf extract concentration, temperature, AgNO3 concentration, effect of ratio of leaf extract to AgNO3 solution,pH and reaction time. The formation of […]
Plant mediated synthesis of silver nanoparticles (AgNPs) is considered as a representative approach in material synthesis for environmental benignity. In this paper, we report an eco-friendly (green) protocol for the preparation of AgNPs using fruit extract of Michelia champaca L. The color change in experimental solution from light brown to dark brown indicates the resonance […]
In this research, Zn2SnO4 nanorods were prepared and structural properties of the nanorods were characterized, developing of wide-range of the optical behavior of Zn2SnO4 nanorods and the antibacterial activity was also investigated using a microwave-assisted method. A zinc stannate (Zn2SnO4) nanorod was synthesized via facile microwave-assisted method using ammonia with cubic spinel structure. The crystallography […]
In-situ polymerization method was adapted to prepare a novel tin cerium phosphate-polyaniline nano composite ion exchange material. The physico-chemical properties of the material were determined using Fourier Transform Infra-Red (FTIR) Spectroscopy, Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), and X-ray diffraction (XRD). X-ray diffraction study showed that the composite material formed is highly crystalline in […]
This paper deals with the synthesis of copper oxide (CuO) nanoparticles by the plant-mediated method using copper acetate monohydrate and neem extract. The formation of nanoparticles was confirmed by UV-Visible spectral studies. P-XRD studies revealed that the average particle size of synthesized nanoparticles was 11.30 nm which was in good agreement with TEM results. Morphology […]
The present investigation evaluates the potential of aqueous seed extract of Abrus precatorius L. for the biosynthesis of silver nanoparticles (AgNPs). The structure of AgNPs was authenticated by the changes in colour as well as the UV-vis spectroscopy, which showed an absorbance maxima peak at 441 nm. The scanning electron microscope (SEM) investigation proved the […]
