Zinc oxide nanoparticles were prepared and subsequently deposited onto the surface of the cotton fiber by ultrasonic irradiation. The optical, structure and morphology of the coated and un-coated cotton were examined by UV, fourier transform infrared spectroscopy, X-ray diffraction analysis (XRD) and...
CB25 and CB500 represent the carbon-black nanoparticles before and after annealing at 500 °C, respectively. Results and discussion Analysis of crystal structure Figure 1a,b presents the XRD patterns of the carbon-black NPs before and after annealing at 500 °C, respectively. Both raw data ...
Antibacterial activity of zinc oxide nanoparticles (ZnO-NPs) has received significant interest worldwide particularly by the implementation of nanotechnology to synthesize particles in the nanometer region. Many microorganisms exist in the range from hundreds of nanometers to tens of micrometers. ZnO-NPs...
3.9.3 Zinc Oxide Nanoparticles (ZnONPs) Zinc oxide nanoparticles have fascinating applications in the field of photonics and nanoelectronics (Yi et al., 2005). The industrial applications of ZnONPs are: dye-sensitized solar cells, pigments (Senthil et al., 2014), photocatalysts (Suliman et...
(1) zinc oxide nanoparticles (ZnO NPs)-induced cell death involves ferroptosis; (2) ZnO NPs-triggered ferroptosis is associated with elevation of reactive oxygen species (ROS) and lipid peroxidation, along with depletion of glutathione (GSH) and downregulation of glutathione peroxidase 4 (GPx4); ...
SEM and TEM analysis shows that the zinc oxide nanoparticles prepared were poly dispersed and the average size ranged from 25 to 40 nm. The particles obtained have been found to be predominantly spherical and the particle size could be controlled by varying the concentrations of leaf broth ...
Zinc oxide nanoparticles (ZnO-NPs) have wide biological applications, which have raised serious concerns about their impact on the health and environment. Although, various studies have shown ZnO-NP toxicity on different cells under in vitro conditions, sufficient information is lacking regarding toxicit...
Zinc nanoparticles (Zn NPs) and zinc oxide nanoparticles (ZnO NPs) are among the most studied nanoparticles. The unique physicochemical, structural, and ph... MA Gacem,V Terzi,A Ould-El-Hadj-Khelil 被引量: 0发表: 2021年 Comparative Study between the Use of Bulk and Nanoparticles of Zinc...
Zinc oxide nanoparticles (ZnO NPs) are considered as very significant and essential material due to its multifunctional properties, stability, low cost and wide usage. Many green and biogenic approaches for ZnO NPs synthesis have been reported using various sources such as plants and microorganisms. ...
andAspergillus niger. Mechanism of action has been ascribed to the activation of zinc oxide nanoparticles by light, which penetrate the bacterial cell wall via diffusion. It has been confirmed from SEM and TEM images of the bacterial cells that zinc oxide nanoparticles disintegrate the cell membrane...
