Carbon Nanotube Membranes Allow Super-fast Fluid Flow

Summary:
Membranes made with carbon nanotubes permit a fluid flow of 10,000 to 100,000 times the speed that conventional fluid flow theory would predict, researchers at the University of Kentucky report in the Nov. 3 issue of Nature. They attribute the speed to the nearly friction-free surface of carbon nanotubes.

Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes' nearly friction-free surface, researchers at the University of Kentucky report in the Nov. 3 issue of Nature.

In their study, Mainak Majumder, Nitin Chopra and Bruce J. Hinds of UK's Chemical and Materials Engineering Department, and Rodney Andrews of UK's Center for Applied Energy Research found the flow dynamics of carbon nanotube (CNT) membranes with pores measuring 7 nanometers in diameter permit a fluid flow exceeded the flows predicted by conventional hydrodynamic predictions.

In their study "Enhanced Flow in Carbon Nanotubes," the researchers note an "aligned CNT membrane has fast transit approaching the extraordinary speed of biological channels. The membrane fabrication is scalable to large areas, allowing for industrially useful chemical separations.

"(E)ach side of the membrane can be independently functionalized. These advantages make the aligned CNT membrane a promising large-area platform to mimic protein channels for sophisticated chemical separations, trans-dermal drug delivery and selective chemical sensing," the researchers say.

Chameleon Camouflage to Give Tanks Cloaking Capabilities

Reuters - Innovations Video Online (Oct. 22, 2014) — Inspired by the way a chameleon changes its colour to disguise itself; scientists in Poland want to replace traditional camouflage paint with thousands of electrochromic plates that will continuously change colour to blend with its surroundings. The first PL-01 concept tank prototype will be tested within a few years, with scientists predicting that a similar technology could even be woven into the fabric of a soldiers' clothing making them virtually invisible to the naked eye.
