Heterostructures of Cut Carbon Nanotube-Filled Array of TiO₂ Nanotubes for New Module of Photovoltaic Devices

Nanomaterials, 2022
In this work, a new photovoltaic device was prepared. The device uses titanium (Ti) foil/TiO2 nanotubes as the photoanode and multi-walled carbon nanotubes (MWCNTs) as a photosensitizer.

Carbon nanotube based 3-D matrix for enabling three-dimensional nano-magneto-electronics [corrected]. [PDF]

PLoS ONE, 2012
This letter describes the use of vertically aligned carbon nanotubes (CNT)-based arrays with estimated 2-nm thick cobalt (Co) nanoparticles deposited inside individual tubes to unravel the possibility of using the unique templates for ultra-high-density ...

Unidirectional and bi-directional growth of carbon nanotubes on the catalytic Co–Zr–N-(O) material

Journal of Materials Research and Technology, 2021
In this paper we have demonstrated the possibility of the MWCNT growth on initially amorphous Co–Zr–N–O alloy thin film which was crystallized during heating followed by formation of Co particles on the surface.

Diffusion of dilute gas in arrays of randomly distributed, vertically aligned, high-aspect-ratio cylinders

Beilstein Journal of Nanotechnology, 2017
In this work we modelled the diffusive transport of a dilute gas along arrays of randomly distributed, vertically aligned nanocylinders (nanotubes or nanowires) as opposed to gas diffusion in long pores, which is described by the well-known Knudsen ...

DISPERSION AND FLOATING PERCENTAGE AS A SIMPLE INDICATOR OF THE AMOUNT OF AMORPHOUS CARBONS IN CARBON NANOTUBE ARRAYS

Journal of Advanced Materials in Engineering, 2021
Carbon nanotubes contain impurities and deamorphization is one of the methods of their purification. In this study, for the first time, a solution of piranha with a ratio of 3:1 (30 ml sulfuric acid + 10 ml hydrogen peroxide) as well as microwave ...

Effect of Enhanced Thermal Stability of Alumina Support Layer on Growth of Vertically Aligned Single-Walled Carbon Nanotubes and Their Application in Nanofiltration Membranes

Nanoscale Research Letters, 2018
We investigate the thermal stability of alumina supporting layers sputtered at different conditions and its effect on the growth of aligned single-walled carbon nanotube arrays.

Comparison of Synchrotron and Laboratory X-ray Sources in Photoelectron Spectroscopy Experiments for the Study of Nitrogen-Doped Carbon Nanotubes

Quantum Beam Science, 2023
The chemical composition and stoichiometry of vertically aligned arrays of nitrogen-doped multi-walled carbon nanotubes (N-CNTs) were studied by photoelectron spectroscopy using laboratory and synchrotron X-ray sources. We performed careful deconvolution

Ordered Arrays of Carbon Nanotubes: From Synthesis to Applications

Nano Biomedicine and Engineering, 2012
Carbon nanotubes are well known for their unique physical properties, which depend on the dimensions of the nanotubes. It is imperative to develop methods for positioning, orienting, and controlling the diameter and length of CNTs before they can be used

Sliding on carbon nanotube arrays

Philosophical Magazine Letters, 2008
Adhesion, friction and wear of Single-Walled Nanotube (SWNT) and multi-walled nanotube arrays have been investigated. SWNT arrays exhibit lower adhesion and friction values on account of the lower van der Waals’ forces resulting from lower packing density and higher flexibility. Wear tests show that both arrays do not wear.
