LaNiO3 nanotubes produced using a template assisted method
Synthesis and Characterization of Modified Carbon Nanotubes with Potassium salts of the Monosubstituted Keggin Polyoxometalates
A novel hybrid of potassium salts of the monosubstituted Keggin polyoxometalates/carbon nanotube nanocomposite is synthesised. Multiwalled carbon nanotubes (MWCNTs) were synthesised by the catalytic chemical vapour deposition method...
Cadmium ion sorption from aqueous solutions by high surface area ethylenediaminetetraacetic acidand diethylene triamine pentaacetic acid-treated carbon nanotubes
A novel and rapid microwave-assisted approach along with Friedel–Crafts acylation has been successfully
introduced for functionalization of carbon nanotubes (CNT) via aliphatic and aromatic carboxylic acids.
This green and efficient...
Purification of Multi-Walled Carbon Nanotubes Arrays by Using Inorganic Chemical Compounds
Carbon nanotubes (CNTs) have unique physical and chemical properties that open attractive possibilities in many applications [1-3]. Similarly, impurities, such as metal and amorphous carbon produced during the synthesis of the CNTs, reduce...
Frequency Analysis of Single-Walled Carbon using a Structural Mechanics Approach
This paper develops a structural mechanic model that analyzes the natural frequency of single-walled
carbon nanotubes (SWCNTs) subjected to fixed-fixed and free-fixed boundary conditions. The necessity of
desirable conditions...
Computer Simulation of Buckling Behavior of SiC Nanotubes via Molecular Dynamics Theory
In this paper the mechanical behavior of silicon carbide (SiC) nanotubes are investigated by molecular dynamics which an effective and accurate way of modeling the behavior of nanostructures. The interactions of atoms in SiCNT are described using...
Investigation of Longitudinal Products Variation in the Course of Carbon Nanotube Synthesis
precursor, which results in different carbon products along the reactor
in the course of carbon nanotube synthesis. The reaction products collected from different parts of the reaction zone, were characterized by scanning electron microscopy (SEM...
A simple recoverable titration method for quantitative characterization of amine-functionalized carbon nanotubes
A simple recoverable titration method is described for quantitative characterization of amine functions attached to the carbon nanotubes (CNTs). This titration is a two-step method, originated from the alkaline nature of amine functions. The amount...
