Water transport control in carbon nanotube arrays
Based on a recent scaling law of the water mobility under nanoconfined conditions, we envision novel strategies for precise modulation of water diffusion within membranes made of carbon nanotube arrays (CNAs). In a first approach, the water diffusion coefficient D may be tuned by finely controlling the size distribution of the pore size. In the second approach, D can be varied at will by means ...
متن کاملOsmotic water transport through carbon nanotube membranes.
We use molecular dynamics simulations to study osmotically driven transport of water molecules through hexagonally packed carbon nanotube membranes. Our simulation setup comprises two such semipermeable membranes separating compartments of pure water and salt solution. The osmotic force drives water flow from the pure-water to the salt-solution compartment. Monitoring the flow at molecular reso...
متن کاملMechanomutable carbon nanotube arrays
Here we present atomistic-based multi-scale simulation studies of a magnetically active array of carbon nanotubes to illustrate the concept of mechanomutability. We show that applying external fields, it is possible to change the nanostructure and to induce a desired mechanical response. Direct numerical simulations are reported that illustrate this concept via mechanical testing through nanoin...
متن کاملCarbon Nanotube Arrays
This colorized, perspective SEM image shows aligned arrays of single-walled carbon nanotubes grown on a quartz substrate in two sequential cycles of chemical vapor deposition (red and blue), as reported by John Rogers and co-workers. The gold line depicts an electrode contact to the array. The SEM image in the background shows regions of dual and single growth on the left and right, respectively.
متن کاملTransport of a Liquid Water-Methanol Mixture in a Single Wall Carbon Nanotube
In this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (SWCNT) is reported. Methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. Some physical properties of the methanol-water mixture such as r...
