due to the high density and the low consumption power in the digital integrated circuits, mostly technology of cmos is used. during the past times, the metal oxide silicon field effect transistors (mosfet) had been used for the design and implementation of the digital integrated circuits because they are compact and also they have the less consumption power and delay to the other transistors. b...

Nowadays, utilisation of Nano-materials as one of the most recent methods of bitumen modification has attracted attention of many researchers. However, not enough research has been pursued on their mixing with bitumen, because of their dimensions and specific properties. In this study, the carbon Nano-tubes were mixed with bitumen using different mixers and some images were recorded employing a...

In this research by equilibrium adsorption isotherms of vitamin B2 (Ribo Flavin) on carbon nano-tubes having the multi wall through several discontinues method has been studied.with the help of spectro photometer (UV / VIS) adsorption chart based on the wavelength of vitamin B2 has been obtained, and the relevant graph is plotted .by considering factor of concentration, the concentration necess...

An explicit derivation of dispersion relations and spectra for periodic Schrödinger operators on carbon nano-structures (including graphene and all types of single-wall nano-tubes) is provided.

Due to the importance effect of magnetic field on the history of long-term radial and circumfer-ential creep strain and radial displacement for a three-phase nano-composite exposed to an internal pressure and placed uniform temperature, the present article subject has been pro-posed. Three-phase nano-composite made of single-walled carbon nano tubes (SWCNTs)/ glass fiber (GF)/vinylester used to...

At the first step CuFe2O4 nanoparticles were synthesized by a fast and facile microwave method. The obtained nanoparticles and modified carbon nano tubes were added to poly styrene matrix. The products were characterized through Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic be...

In this work, the nonlocal elastic waves in a fluid conveying armchair thermo elastic single walled carbon nanotube under moving harmonic load is studied using Eringen nonlocal elasticity theory via Euler Bernoulli beam equation. The governing equations that contains partial differential equations for single walled carbon nanotube is derived by considering thermal and Lorenz magnetic force. The...
