Adsorption of CO2 on the surface of Single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (SWCNTs) were studied through using density functional theory (DFT) calculations. Optimizations of geometric were performed at the B3PW91 level of 6-311++G** method standard basis set using GAUSSIAN 03 package of program [1]. Structural models were optimized and adsorption energies, band […]
This article reports an experimental study of heat transfer characteristics of multi-walled carbon nanotubes (MWCNTs). These nanofluids, consisting of water with different weight concentrations of nanofluid (0.0.1–0.145% wt.), have flown in counter flow plate heat exchanger under turbulent conditions (the range of Reynolds numbers 2500-6500) for cooling applications. The nanofluid was prepared by dispersing MWCNT […]
In this present work, MWCNTs modified NiFe2O4 NPs (M-MWCNT) were successfully fabricated based on a hydrothermal route, and then utilized to Pb(II) sorption from an aqueous solution. The M-MWCNT was characterized and analyzed by SEM, TEM, FTIR, XRD, and VSM techniques. TEM image demonstrated that the size of NiFe2O4 nanoparticles in the structure of MWCNT […]
