In this review article, the implementation of nanomaterials such as metal oxides and their composites, carbon nanotubes, dendrimers, and polymer nanocomposites in wastewater decontamination have been discussed. Nanomaterials have a lot of potentials, due to their high pollution sensing ability and larger surface area. Nanomaterials are ideal for eliminating harmful heavy metals and eradicating severe […]
Quantum Dots are a group of semiconductors nanomaterials whose size is about less than 10 nm exhibiting unique optical and electric properties which impart different advantages in terms of wide and continuous absorption spectra, narrow emission spectra, high quantum yield, long fluorescence lifetimes, and high photostability. Based on the unique properties of quantum dots have a variety of […]
The effect of milling process on TiO2 nanopowders and functional properties of TiO2 coated cotton fabric was investigated. The XRD analysis reveals that the milled TiO2 nanopowders reduce its size in Nano scale when milling time increases. SEM analysis reveals that the milled TiO2 powder shows a seed-like structure. FTIR spectra show the presence of […]
In the current study, a novel S-scheme heterojunction photocatalyst was fabricated through a simple hydrothermal method from CeO2 nanoparticles and WO3 nanoplates in presence of tragacanth mucilage as natural surfactant. The prepared heterojunction photocatalyst was used for degradation of Nitenpyram insecticide under visible light irradiation. The successful synthesis of the heterojunction samples was confirmed by […]
Recently, with the increase in diseases caused by bacterial and viral infections, the need for antibacterial agents has widely increased. On the other hand, with the development of drug resistance to organic groups of antibiotics, new antibiotics have attracted the attention of researchers because new methods are needed to reduce the activity of bacteria. Nanotechnology […]
In this study, we report the synthesis of magnetite (Fe3O4) nanoparticles using Catha Edulis plant leaf extract as bioreducing agents and investigation of its efficiency as an adsorbent for hexavalent chromium Cr(VI) removal from aqueous solutions. The synthesized NPs were characterized using X-ray diffraction (XRD) spectroscopy, Fourier Transforms Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), […]
In this paper, we optimize the electrical characteristics of Nano-scale symmetric double-gate metal oxide semiconductor field effect transistors (DG-MOSFETs) for digital applications using a genetic algorithm. We use a single-objective genetic algorithm to optimize the threshold voltage (Vth) with a distinct analytical relationship. The optimization of the threshold voltage is accomplished for three cases with […]
In this report, we intend to synthesize iron oxide (Fe2O3), erbium oxide (Er2O3), and a composite of erbium oxide/iron oxide (Er2O3/Fe2O3) nanoparticles (NPs) by a microwave irradiation technique. After the synthesis, we explore the various physicochemical properties of the sample with the help of various systematic characterization techniques. First, the prepared sample has been subjected […]
