The results of ab initio density functional theory calculations of molecular physisorption on a number of different adsorption sites on a graphene sheet and on a (10, 0) single walled carbon nanotube are discussed. Both the Vosko-Wilk-Nusair (VWN) local density approximation (LDA) functional and the Perdew-Wang (PW91) generalized gradient approximation (GGA) functional were employed in calculat...

wileyonlinelibrary.com internal/external surface sites of the nanostructure. Thus, the big challenge is in the nanostructure architecture where all of these parameters need to be optimized simultaneously. For the case of a supercapacitor, the nanostructure material is used as the framework to store and transport charges between two parallel electrodes. A conventional supercapacitor usually cons...

A single-walled carbon nanotube was exploited for its semi-flexible pseudo-one-dimensional nanostructure as a unique scaffold to display multivalent carbohydrate ligands, with a specific demonstration showing that galactosylated carbon nanotubes were effective in the capturing of pathogenic Escherichia coli in solution.

This paper describes the fabrication and characterization of a hybrid nanostructure comprised of carbon nanotubes (CNTs) grown on graphene layers for supercapacitor applications. The entire nanostructure (CNTs and graphene) was fabricated via atmospheric pressure chemical vapor deposition (APCVD) and designed to minimize self-aggregation of the graphene and CNTs. Growth parameters of the CNTs w...

Low cost disposable working electrodes are specifically desired for practical applications of electrochemical detection considering maturity of electrochemical stations and data collection protocols. In this paper double-sided conductive adhesive carbon tape with nanostructure was applied to fabricate disposable working electrodes. Being supported by indium tin oxide glass, the prepared carbon ...

Over the past decade, electrical detection of chemical and biological species using novel nanostructure-based devices has attracted significant attention for chemical, genomics, biomedical diagnostics, and drug discovery applications. The use of nanostructured devices in chemical/biological sensors in place of conventional sensing technologies has advantages of high sensitivity, low decreased e...

The effect of nanostructure on the thermal oxidation of atomized iron has been investigated. Above 500 o C atomized iron is oxidized in the presence of air. However, when iron is compacted with multiwalled carbon nanotubes (MWCNT) this oxidation is shifted by more than 100 o C. Iron is protected by the nanostructure environment A large number of compositions of atomic ratios of iron and MWCNT h...
