Additions of high modulus nano particles to Aluminum alloys offer the potential to develop a lightweight composite with high mechanical properties. It is extremely difficult to disperse nano-sized ceramic particles uniformly in molten metal. In order to investigate the effect of nano-alumina on the microstructure and mechanical properties of composite, a new method was used in stir casting to a...

Temperature distribution is a key function for analyzing and optimizing the thermal behavior of various process equipments. Moving bed reactor (MBR) is one of the high-tech process equipment which tries to improve the process performance and its energy consumption by fluidizing solid particles in a base fluid. In the present study, thermal behavior of MBR has been analyzed through mathematical ...

in the present study, we investigate the potentiometric behavior of cu2+ carbon paste electrodes based on two mercapto compounds 2-ethylmino-5-mercapto-1,3,4-thiadiazole (eamt) and 2-acetylamino-5-mercapto-1,3,4-thiadiazole (aamt) self-assembled on gold nano-paricle (gnp) as ionophore. then, the results obtained from the modified electrodes are compared. the self-assembled ionophores exhibit a ...

– The Wigner equation taking into account both the non-local potential operator and a scattering operator represents a suitable physical model for carrier transport in nano structures. In this paper a new Monte Carlo method is proposed for the solution of the stationary Wigner equation. Scattering can be included at the level of the semi-classical Boltzmann scattering operator, whereas coherent...

biopolymer based nano-complex is a category of nano-carriers which are produced by interaction between protein and polysaccharide. they can carry hydrophobic nutriciuticals in aqueous solutions and also cause to increase of protection and bioavailability of encapsulated active materials. in this research, gellan-caseinate complexes containing omega3 were produced by adding gellan solutions to c...

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 new magnetophoresis method to determine the magnetic susceptibility of single nano/microparticles was developed by applying Brownian motion analysis to determine the size of the particle. This method could measure simultaneously both the magnetophoretic velocity and the radius of the identical single nano/microparticles, which are necessary for the determination of the magnetic susceptibility...
