Here we report a strong affinity of amine-functionalised multi-walled carbon nanotubes for spider silk, with coating assisted by a water and mechanical shear method. The nanotubes adhere uniformly and bond to the silk fibre surface to produce tough, custom-shaped, flexible and electrically ...
Using large-scale DFT calculations, we have investigated the structural and electronic properties of both armchair and zigzag graphdiyne nanotubes as a function of size. To provide insight in these properties, we present new detailed calculations of the structural relaxation energy, effective electron/ho...
Carbon nanotubes have long been described as rolled-up graphene sheets. It is only fairly recently observed that longitudinal cleavage of carbon nanotubes, using chemical, catalytical and electrical approaches, unzips them into thin graphene strips of va
Based on different spinning methods, carbon nanotube fibers exhibit extremely rich assembly structures. Compared with its microstructure, the orientation, tightness and entanglement of carbon nanotubes in fibers, radial distribution of fibers, surface morphology and other structural properties further determine...
Structural peculiarities: shape, orientation, defects of catalyst particles and fillings of as-prepared specimens were studied using HRTEM analysis. It was shown that orientations of metal particles, located inside carbon nanotubes (nanofibers), along the longitudinal axis for fcc and bcc crystal ...
Structural and mechanical properties of armchair, zig-zag and chiral single-walled carbon nanotubes are computed by employing Molecular Dynamics simulation... MG Mashapa,SS Ray - 《Journal of Nanoscience & Nanotechnology》 被引量: 0发表: 2010年 Mechanical properties of carbon nanotube by molecular ...
reaction (sensitive to any condition changed), the setup in this work leads to a different mechanism of structural transition leading to the formation and stabilization of T-carbon NWs. The difference lies in the time scales of energy transfer from the laser to the MWCNTs and their subsequent ...
Carbon nanotubes (CNTs) are cylindrical-tubule structures made from graphite with exceptional physical properties that have been harnessed in biological applications such as drug delivery and biosensors14,15. They are capable of crossing plant cell walls and membranes due to their high aspect ratio, ...
10, the rotation of nanotubes toward the x-axis in the first stage decreased the angle from θ0 to θ1, and the interaction between CNT bundles was also enhanced. As the compression stress level increased, the rotation extent increased from θ1 to θ2. According to Eqs. (5), (6), ...
