Magnetic Fe3O4 nanoparticles coated with thiol functionalized mesoporous silica (TFMS) were prepared and usedas a novel adsorbent for Pb2+ and Ag+ removal. FTIR spectra confirmed the Fe3O4 nanoparticle cores coated with mesoporous silica and indicated the presence of thiol groups on the surface. XRD analyses showed that synthesized adsorbent has a face-centered cubic magnetite phase […]
This study evaluated the light transmission characteristics of a single modular fiber with a cylindrical microchannel using the FDTD method. To this end, various microchannel diameters (4-11μm) were explored. The SMF included a silica core (n=1.4) coated by a nanodiamond layer with a refractive index of 2.42. The impact of Fabry-Perot resonance was evidently detected […]
In this research, a new organic–inorganic hybrid photocatalyst (TCMP@TiO2) was successfully synthesized through supporting tetrachloromenthoxyphosphor (III) (TCMP) on titanium dioxide (TiO2) for elimination of methyl violet (MV) color from water media. The hybrid inorganic-organic catalyst of this nanocomposite was characterized by 1H-NMR, 31P-NMR, 13C-NMR, UV-Vis, IR, SEM, and mass spectrometry methods. The maximum dye elimination […]
Magnetic nanoparticles have received much attention in synthesizing organic compounds due to their unique properties such as high contact surface, recyclability, and easy separation. In this study, Rice husk ash (RHA), an agriculture waste, was used as a silica source for MCM-41 synthesis. Ag2S/RHA-MCM-41 nanocomposite synthesized and characterized with FT-IR, SEM, and XRD. Prepared nanocomposite […]
The electrical and thermal properties of polymer composites are enhanced by the incorporation of nano and micron fillers. Reported work on polymer composites with the combination of micro and nano sized fillers like silicon dioxide, alumina, silicon carbide, molybdenum disulphide, and graphite are limited. In this investigation, the AC conductivity of composites with the combination […]
In the last decade, the bio-assisted synthesis of nanoparticles has been significantly exploited seeing the shortfall of chemical synthesis and urgent need to find the substitution. The chemical synthesis of nanoparticles is a rapid process, which might be appealing in various frontiers but has got some serious issues to take care of. In pursuit of […]
Full adder cells are the major fundamental elements of larger arithmetic circuits, which are mostly located along the critical path of circuits. Therefore, the design of low-power and high-speed full adder cells is critical. In this paper, there are two new inexact full adder cells proposed based on Carbon Nanotube Field Effect Transistor (CNFET) technology. Using the HSPICE simulator […]
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 […]
A successful drilling operation depends strongly on a useful drilling fluid system. Using nanoparticles (NP)s to formulate intelligent drilling fluids gives them a wide range of optimal properties under different operating conditions and resolves any operational problems. In this study, in order to provide an effective solution for improving the rheological and high pressure/high temperature […]
Green synthesis of metal nanoparticles (MNPs) is attracting the attention of chemists as it is cost effective and environment benign technique. Hence it is preferred to methods which use toxic reagents in the synthesis of MNPs. In. In this study, copper oxide nanoparticles (Cu2ONPs) were synthesized using Allium cepa (AC) and Raphanus sativus (RS) aqueous […]
