Multiwall carbon nanotubes (CNTs) and iron oxide impregnated carbon nanotubes (CNTs-iron oxide) were investigated for the adsorption of hazardous toluene and paraxylene (p-xylene) from aqueous solution. Pure CNTs were impregnated with iron oxides nanoparticles using wet impregnation technique. Various characterization techniques including thermogravimetric analysis, scanning electron microscopy...

Electrical sensitivity of a beryllium oxide nanotube (BeONT) was examined toward (C4H5N) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31(d) level, and it was found that the adsorption energy (Ead) of pyrrole on the pristine nanotubes is   a bout -48.58kcal/mol. But when nanotubes has been doped with S and P atomes , the adsorptio...

The formation of nanosized catalyst particles for the growth carbon nanotubes can be carried out during crystallization amorphous films consisting two metals, one which has higher free energy oxide. During annealing in presence oxygen, this metal is oxidized with reduction second metal, leads to nanoparticles embedded oxide first metal. This process been experimentally and theoretically studied...

Tungsten oxide/tungsten sulfide (W18O49@WS2) core-shell nanorods prepared via a controlled sulfidization reaction of W18O49 nanowhiskers showed hydrogen evolution reaction (HER) activity superior to WS2 nanotubes, indicating the critical role of a highly conductive oxide core in enhancing HER activity.

It is understood that nano-channels of graphene oxide membranes have a water flow mechanism which is similar to the water flow inside carbon nanotube pores. The water transport mechanisms recently proposed by various researchers suggest that membranes composed of graphene oxide laminates could be regarded as an assembly of many tiny carbon nanotubes stacked together with attached functional gro...

This paper reports a novel and efficient strategy for fabricating sub-100 nm metal ring arrays using a simple printing process. Vertically aligned carbon nanotubes that are supported by hexagonally ordered channels of alumina matrices are used as a stamp to print nanoscale ring patterns, which is a very unique stamping platform that has never been reported. Using this strategy, uniform nanoring...
