Carbon Nanotubes & Nanofluids

The green house effect is considered as one of the most important environmental problems that hu- manity faces. CO2 is acknowledged as the most conspicuous greenhouse gas, with its atmospheric concentration being continuously increased. More than 30 billion tons of CO2 are being produced every year with fossil fuel power plants along with the increasing number of all kinds of vehicles to be the main releasing sources. The high amounts of CO2 increasingly dispersed in the atmosphere have motivated academia and industry to develop new technologies for CO2 sequestration and storage. To support the development of the Nanogreen Gas Filter - Carbon Nanotubes Gas Filter for CO2 filtration, which has attracted the interest of major manufacturers with (potential) impact on global scale (UK Patent 2479257-A, US Patent 20130042762 A1) we have performed a number of Molecular Dynamics studies to shed light on carbon adsorption from single- and multi-walled CNTs.

Projections of CO2 distributions in (8, 8), (12, 12), (16,16) and (20,20) single-walled nanotubes at T= 300 K and P = 20 bar.
