Self-assembled hierarchical solid surfaces are very interesting for wetting phenomena, as observed in a variety of natural and artificial surfaces. Here, we report single-walled (SWCNT) and multi-walled carbon nanotube (MWCNT) thin films realized by a simple, rapid, reproducible, and inexpensive filtration process from an aqueous dispersion, that was deposited at room temperature by a dry-trans...

The common aggregation of single-wall carbon nanotube (SWCNT) in solution is the critical obstacle to elucidate their unique physico-chemical characteristics and biological properties. Therefore, it is very important to overcome this barrier through manipulation of the weak interaction of small molecules with nanotube surface limited interface. A highly dispersed SWCNT system was achieved by bi...

The functionalization of single wall carbon nanotubes (SWCNTs) is a very actively discussed topic in contemporary nanotube literature because the planned modification of SWCNT properties is believed to open the road towards real nanotechnology applications. In this contribution, some recent results are reported on the subject. Covalent attachment of functional groups, their influence on tube-tu...

In this article, numerical simulations of the rotational flow water-based magnetohydrodynamic (MHD) nanofluid containing single-wall carbon nanotube (SWCNT) and hybrid single- multiple-wall (SWCNT-MWCNT) over a stretching sheet are performed. The primary goal is to improve thermal transport efficiency due CNTs extraordinary conductivity. 3D governing equations for microorganism concentration, e...

The role of water in carbon feed on the surface-guided growth of horizontally aligned single-walled carbon nanotubes (HA-SWCNTs) was investigated. It is shown that the amount of water can be optimized to favor HA-SWCNT growth, which is proposed to be due to selective etching of carbon deposits at carbon–metal interface. Without water, nanotube–nanotube interaction and carbon accumulation at the...

The interaction between some heavy metal ions such as of Pb(II), Cd(II) and Cu(II) ions from aqueous solution adsorbed by single walled carbon nanotube (SWCNTs) and carboxylate group functionalized single walled carbon nanotube (SWCNT-COOH) surfaces were studied by atomic absorption spectroscopy. The effect of contact time, pH, initial concentration of ion, ionic strength and temperature on the...

Single wall carbon nanotube modified glassy carbon electrode (SWCNT/GCE) was used for flow-injection analysis (FIA) for phenolic compounds (phenol (P), 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorphenol (TCP) and pentachlorophenol (PCP)). Experimental variables such as the detection potential, flow rate and pH of the carrier solution, 0.1 M sodium acetate, were optimized. Under...

We present single-wall carbon nanotube (SWCNT) incorporated liquid crystal elastomer (LCE) nanocomposites that demonstrate strong, reversible photoactuation. The matrix nematic LCEmaterial possesses reversible thermal deformation, while SWCNTs perform photothermal energy conversion and local heat dissipation upon irradiation. The resultant SWCNT–LCE nanocomposites exhibit effective photoactuati...

Carbon nanotubes have unique properties like high stability, high surface to mass ratio and so on which make them suitable for medicinal purpose applications. Treatment of cancer by organoplatinum agents like Cisplatin has become unresponsive in most cases due to low distribution of drug in biological fluids, inability of drug to cross cellular membranes and low stability in biological environm...
