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.

Flow conveying and diagnosis with carbon nanotube arrays [PDF]

, 2006
Dense arrays of aligned carbon nanotubes are designed into strips, nanowicks, as a miniature wicking element for liquid delivery and potential microfluidic chemical analysis devices. Liquid wicks away along the nanowicks spontaneously.

First-Principles Study of Chemisorption of Oxygen and Aziridine on Graphitic Nanostructures [PDF]

, 2009
Using ab initio plane wave pseudopotential calculations, we study the energetics and structure of adsorbed linear arrays of oxygen and aziridine on carbon nanotubes, graphitic ribbons, and graphene sheets.

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 ...

Inherent-opening-controlled pattern formation in carbon nanotube arrays [PDF]

, 2007
We have introduced inherent openings into densely packed carbon nanotube arrays to study self-organized pattern formation when the arrays undergo a wetting–dewetting treatment from nanotube tips.

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.

Gas Biosensor Arrays Based on Single-Stranded DNA-Functionalized Single-Walled Carbon Nanotubes for the Detection of Volatile Organic Compound Biomarkers Released by Huanglongbing Disease-Infected Citrus Trees. [PDF]

, 2019
Volatile organic compounds (VOCs) released by plants are closely associated with plant metabolism and can serve as biomarkers for disease diagnosis. Huanglongbing (HLB), also known as citrus greening or yellow shoot disease, is a lethal threat to the ...

Theoretical and Experimental Studies of Schottky Diodes That Use Aligned Arrays of Single Walled Carbon Nanotubes [PDF]

, 2010
We present theoretical and experimental studies of Schottky diodes that use aligned arrays of single walled carbon nanotubes. A simple physical model, taking into account the basic physics of current rectification, can adequately describe the single-tube
