Macroscale nanotube separation

Macroscale Experimental Evidence of a Reduced- Mobility Non-bulk Polymer Phase in Nanotube- Reinforced Polymers

Because of their outstanding physical properties, the use of carbon nanotubes within a polymer matrix has been proposed as a means to fabricate multifunctional composite materials with outstanding mechanical, electrical, and thermal properties. To date, experimental work studying the mechanical response of a nanotube reinforced polymer (NRP) has typically focused on the effective elastic modulu...

Separation and liquid chromatography using a single carbon nanotube

Use of a single template-grown carbon nanotube as a separation column to separate attoliter volumes of binary mixtures of fluorescent dyes has been demonstrated. The cylindrical nanotube walls are used as stationary phase and the surface area is increased by growing smaller multi-walled carbon nanotubes within the larger nanotube column. Liquid-liquid extraction is performed to separate selecti...

Separation of ibuprofen drugs enantiomers by using chiral carbon nanotube with molecular dynamics simulation

Background: The separation of drug enantiomers in the pharmaceutical industry is of great importance since most organic compounds are chiral. The main purpose of this study was to calculate the binding energy of ibuprofen isomers interacting with the CNT, according to various adsorption configurations. Moreover, we have evaluated the performance of (16.4) chiral carbon nanotube for separation o...

Simulating macroscale brain circuits with microscale resolution

Macroscale Transformation Optics Enabled by Photoelectrochemical Etching.

Photoelectrochemical etching of silicon can be used to form lateral refractive index gradients for transformation optical devices. This technique allows the fabrication of macroscale devices with large refractive index gradients. Patterned porous layers can also be lifted from the substrate and transferred to other materials, creating more possibilities for novel devices.
