Biological control agents are useful components in the enhancement of plant disease resistance and improvement of soil properties. Effect of biological control agents (BCAs) as a disease control method in plants is hampered by their vulnerability to environmental and edaphic conditions. This study entailed the use of chitosan-silica nanocomposites for delivery of BCAs. Effect of BCAs-nanocompos...

TiO2@SBA-15 mesoporous nanocomposite are of increasing interest as materials for photocatalytic applications. We report here an investigation on the characteristics of TiO2@SBA-15 prepared by introducing titanium by a grafting technique. The samples, having TiO2 loadings of 10%, have been characterized by XRF, XRD, FT-IR (CO adsorption), porosimetry, SEM, HRTEM, and UV-Visible diffuse reflectan...

The separation factor, aM-0= ( 1 8 0 / 1 6 0 ) magnetite/' ( 1 8 0 / 1 6 0 ) atmospheric oxygen, between the magnetite crust of iron meteorites and atmospheric oxygen has been determined to be 0.9946 ± 0.0005. It is concluded that this fractionation of the oxygen isotopes is the consequence of an equilibrium isotope effect at high temperatures. It can be assumed that this is also valid for cosm...

A semiconductor/metal nanocomposite is composed of a porosified silicon wafer and embedded ferromagnetic nanostructures. The obtained hybrid system possesses the electronic properties of silicon together with the magnetic properties of the incorporated ferromagnetic metal. On the one hand, a transition metal is electrochemically deposited from a metal salt solution into the nanostructured silic...

The present work reports development of a magnetic hydrogel adsorbent material based on the polysaccharide, gum acacia. This graft copolymer nanocomposite acacia and poly(3-chloro-2-hydroxypropylmethacrylate) has been made using microwave assisted technique. Magnetite nanoparticles have generated by in-situ method trapped in network structure. parent hybrid were evaluated as adsorbents for sequ...

Abstract The import marvel in multiferroic substances is the existence of spontaneous polarization and magnetization which enable these materials meet needs technological applications. Multiferroic BiFeO 3 nickel-doped magnetite was synthesized separately by flash co-precipitation methods, respectively. two phases were confirmed X-ray diffraction (XRD), scanning electron microscope (SEM) Fourie...

Outdoor electronic equipment such as signal stations, radar units, and cellular base stations would benefit from electromagnetic interference (EMI) shielding systems, but ice accretion on the surface of these facilities often causes critical challenges, especially in cold regions winter season. In this study, icephobic nanocomposite electrospun membranes were developed via a two-step process re...
