Aniline Adsorption on the Surface of a BN Nanotube: A Computational Study [PDF]

open access: yesInternational Journal of New Chemistry, 2014
Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward aniline (C6H5NH2) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of aniline on ...

Investigation of carbon nanotube quantum dots connected to ferromagnetic leads [PDF]

open access: yes, 2015
The implementation of ferromagnetic contacts in complex nanoelectronic devices, e.g. in spin-valves bears great potential for applications and fundamental investigations. Spin-valves are structures with two magnetic contacts and a non-magnetic medium (

Convergence Gas Sensors with One-Dimensional Nanotubes and Pt Nanoparticles Based on Ultraviolet Photonic Energy for Room-Temperature NO2 Gas Sensing

open access: yesNanomaterials, 2023
Zinc oxide (ZnO) is a promising material for nitrogen dioxide (NO2) gas sensors because of its nontoxicity, low cost, and small size. We fabricated one-dimensional (1D) and zero-dimensional (0D) convergence gas sensors activated via ultraviolet (UV ...

Enhanced Antioxidant Activity under Biomimetic Settings of Ascorbic Acid Included in Halloysite Nanotubes

open access: yesAntioxidants, 2019
Antioxidant activity of native vitamin C (ascorbic acid, AH2) is hampered by instability in solution. Selective loading of AH2 into the inner lumen of natural halloysite nanotubes (HNT) yields a composite nanoantioxidant (HNT/AH2), which was ...

Spectroscopic detection of carbon nanotube interaction with amphiphilic molecules in epoxy resin composites [PDF]

open access: yes, 2005
Incorporation of carbon nanotubes into epoxy resin composites has the effect of increasing electrical conductivity at low percolation levels. An amphiphilic molecule such as palmitic acid has been used to increase the surface contact area and improve ...

Characterization and evaluation of carbon nanotube Bucky-Paper membranes for direct contact membrane distillation [PDF]

open access: yes, 2010
Self-supporting carbon nanotube (CNT) Bucky-Papers have unique structural and surface properties which can be utilised in many applications. In this work we characterised pure self-supporting CNT membranes, where CNTs were held together only by Van der ...
