Background & objectives: Xylene, which can pollute the water sources, is widely used as a solvent in insecticide manufacture, dye and leather and other industries. Adsorption is one of the most common processes used to treat the contaminated aqueous solutions by xylene. Therefore, the aim of this study was to compare the xylene removal efficiency and adsorption isotherms of magnetic nanoparticl...
Iron-dextran nanoparticles functionalized with T cell activating proteins have been used to study T cell receptor (TCR) signaling. However, nanoparticle triggering of membrane receptors is poorly understood and may be sensitive to physiologically regulated changes in TCR clustering that occur after T cell activation. Nano-aAPC bound 2-fold more TCR on activated T cells, which have clustered TCR...
We show how the magnetization of nano-objects can be efficiently regulated. Several types of nanosystems are considered: magnetics nanomolecules, magnetic nanoclusters, polarized nanomolecules, and magnetic graphene. These nano-objects and the structures composed of them enjoy many common properties, with the main difference being in the type of particle interactions. The possibility of governi...
A bio-based magnetic nano-catalyst (Fe3O4@nano-dextrin/Ti(IV)) was synthesized via the preparation of Fe3O4@nano-dextrinas magnetic support and then its treatment with titanium tetrachloride (TiCl4). The properties of this catalyst were characterized by different kinds of techniques such as FT-IR, FESEM, TEM, ICP, XRF, VSM and TGA....
in this study, nonlocal nonlinear instability and the vibration of a double carbon nanotube (cnt) system have been investigated. the visco-pasternak model is used to simulate the elastic medium between nanotubes, on which the effect of the spring, shear and damping of the elastic medium is considered. both of the cnts convey a viscose fluid and a uniform longitudinal magnetic field is applied t...
Gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. High specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. They are made by addition a suitable gellant to liquid propellants. In this research, nano Al particles have been used in UDMH gel fuel. The gel...
