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
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
Cellular mechanisms of neuropathic pain, morphine tolerance, and their interactions
TL;DR: In this article, a site of action involved in both hyperalgesia and morphine tolerance is found in the superficial laminae of the spinal cord dorsal horn, which may be interrelated at the level of the dorsal horn by common neural substrates.
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
Fabrication of a carbon nanotube-embedded silicon nitride membrane for studies of nanometer-scale mass transport
TL;DR: In this paper, a multwall carbon nanotubes embedded in a silicon nitride matrix was fabricated for fluid mechanics studies on the nanometer scale, and an upper limit of 2.4 × 10-8 mol/m2 s was determined, indicating extremely slow transport through the membranes.
