Carbon Nanotube Actuators

open access: yesScience, 1999
Electromechanical actuators based on sheets of single-walled carbon nanotubes were shown to generate higher stresses than natural muscle and higher strains than high-modulus ferroelectrics. Like natural muscles, the macroscopic actuators are assemblies of billions of individual nanoscale actuators.

Optical Absorption and Raman Spectroscopy Study of the Fluorinated Double-Wall Carbon Nanotubes [PDF]

open access: yes, 2006
Double-wall carbon nanotube (DWNT) samples have been fluorinated at room temperature with varied concentration of a fluorinating agent BrF3. Content of the products estimated from X-ray photoelectron data was equal to CF0.20 and CF0.29 in the case of ...

Carbon Nanoparticles-Decorated Carbon Nanotubes [PDF]

open access: yesScientific Reports, 2020
AbstractMulti walled carbon nanotubes (MWCNTs) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. Carbon nanospheres and MWCNTs were mixed by equal mass ratios for different durations. The products were characterized by Raman spectroscopy, thermal gravimetric analysis, nanoscanning electron microscopy, transmission ...

Simulation and fabrication of carbon nanotube–nanoparticle interconnected structures [PDF]

open access: yesMechanical Sciences, 2021
With the rapid development of nanotechnology, the size of a device reaches sub-nanometer scale. The larger resistivity of interconnect leads to serious overheating of integrated circuits.

Efficient carbon nanotube growth from pyrolysis of citric acid-based small organic molecules

open access: yesCarbon Trends, 2023
We prepare carbon nanotubes based on the cross-linking reaction between small organic molecules citric acid and amino urea or ethylenediamine. Factors affecting the yield of carbon nanotube are optimized and catalytic effect of hydrated metal nitrate on ...

Hydrogen Evolution on Hydrophobic Aligned Carbon Nanotube Arrays [PDF]

open access: yes, 2009
We investigate for the first time hydrophobic carbon nanotube-based electrochemical cells as an alternative solution to hydrogen sorting. We show that the electrically conducting surface of the nanotube arrays can be used as a cathode for hydrogen ...

Carbon Nanotubes in Biomedicine [PDF]

open access: yesTopics in Current Chemistry, 2020
Nowadays, biomaterials have become a crucial element in numerous biomedical, preclinical, and clinical applications. The use of nanoparticles entails a great potential in these fields mainly because of the high ratio of surface atoms that modify the physicochemical properties and increases the chemical reactivity.

Charge distribution of metallic single walled carbon nanotube–graphene junctions

open access: yesNew Journal of Physics, 2014
We report numeric and analytic calculations of the electrostatic properties for armchair carbon nanotube–graphene junctions. Using a semi-empirical method we first demonstrate that the equilibrium distance between a carbon nanotube and a graphene sheet ...
