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...

using c2h2, 112 and as gases at 550'c, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by dc magnetron sputtering. aystamless steel andfe/cteal, by thermal chemical vapor deposition (tcvd) the surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the cnt's growth is cri...

the main objective of the present study is to investigate the feasibility of using carboxymethyl chitosan magnetic nanoparticles (ccmn) for the adsorption of cd2+. the study also reports important parameters, which affect the adsorption process, i.e., ph, adsorbent dose, contact time and concentration of cd2+, using box-behnken designs. firstly, functional carboxymethyl chitosan magnetic nanopa...

Nano-Sn/C composites are ideal anode materials for high energy and power density Li-ion batteries. However, because of the low melting point of Sn and the tendency of grain growth, especially during high temperature carbonization, it has been a significant challenge to create well-dispersed ultrasmall Sn nanoparticles within a carbon matrix. In this paper, we demonstrate an aerosol spray pyroly...

background: the presence of heavy metals in the environment especially in water supplies have caused many concerns because of their toxicity and non-degradability. hexavalent chromium (cr) is one of the most toxic metals which is used in many industries, so it is essential to remove it from industrial wastewater. in this study, we made a comparison between different adsorption isotherms in the ...

using a magnetic property measurement system (mpms), we measure magnetic susceptibility continuously at frequencies from 0 to 1000 hz for three different superparamagnetic (sp) grain sizes of magnetite (5nm, 7 nm and 10 nm) suspended in hydrocarbons (ferrofluids). our results confirm non-zero values of frequency-dependent susceptibility in the fine tail of nano-sized grains and provide new empi...

Development of nano and biotechnologies encouraged us to develop a concept of automated building, which will significantly reduce the many negative impacts of traditional construction on the environment. The paper describes the concept of Nanoto meter-scale building, a new way of building, which unfolds from the nano into the meter range. The concept is based on bionanorobots, producing buildin...

Carbon nanotubes (CNTs) have attracted attention for their remarkable electrical properties and have being explored as one of the best building blocks in nano-electronics. A key challenge to realize such potential is the control of the nanotube growth directions. Even though both vertical growth and controlled horizontal growth of carbon nanotubes have been realized before, the growth of comple...
