Journal ArticleDOI
Fast Mass Transport Through Sub-2-Nanometer Carbon Nanotubes
Jason K. Holt,Hyung Gyu Park,Hyung Gyu Park,Yinmin Wang,Michael Stadermann,Alexander B. Artyukhin,Costas P. Grigoropoulos,Aleksandr Noy,Olgica Bakajin +8 more
TL;DR: Gas and water flow measurements through microfabricated membranes in which aligned carbon nanotubes with diameters of less than 2 nanometers serve as pores enable fundamental studies of mass transport in confined environments, as well as more energy-efficient nanoscale filtration.
Journal ArticleDOI
Ultimate permeation across atomically thin porous graphene.
Kemal Celebi,Jakob Buchheim,Roman M. Wyss,Amirhossein Droudian,Patrick Gasser,Ivan Shorubalko,Jeong-Il Kye,Changho Lee,Hyung Gyu Park +8 more
TL;DR: Highly efficient mass transfer across physically perforated double-layer graphene is reported, having up to a few million pores with narrowly distributed diameters between less than 10 nanometers and 1 micrometer, in agreement with predictions of 2D transport theories.
Journal ArticleDOI
Ion exclusion by sub-2-nm carbon nanotube pores
Francesco Fornasiero,Hyung Gyu Park,Jason K. Holt,Michael Stadermann,Costas P. Grigoropoulos,Aleksandr Noy,Aleksandr Noy,Olgica Bakajin,Olgica Bakajin +8 more
TL;DR: It is shown that carbon nanotube membranes exhibit significant ion exclusion that can be as high as 98% under certain conditions, which strongly support a Donnan-type rejection mechanism, dominated by electrostatic interactions between fixed membrane charges and mobile ions.
Journal ArticleDOI
Nanofluidics in carbon nanotubes
Aleksandr Noy,Hyung Gyu Park,Hyung Gyu Park,Francesco Fornasiero,Jason K. Holt,Costas P. Grigoropoulos,Olgica Bakajin +6 more
TL;DR: In this paper, the authors proposed a water transport mechanism that has a distinct similarity to the transport mechanisms of biological ion channels and demonstrated the importance of nanotube structure in enabling ultra-efficient transport through the pore.
Journal ArticleDOI
Fast water transport in graphene nanofluidic channels
Quan Xie,Mohammad Amin Alibakhshi,Shuping Jiao,Zhi Ping Xu,Marek Hempel,Jing Kong,Hyung Gyu Park,Chuanhua Duan +7 more
TL;DR: It is shown that the hydraulic resistance and slippage of single graphene nanochannels can be accurately determined using capillary flow and a novel hybrid nanochannel design without estimating the capillary pressure.
