Size effect in ion transport through angstrom-scale slits
A. Esfandiar, B. Radha, F. C. Wang +6
It has been an ultimate but seemingly distant goal of nanofluidics to controllably fabricate capillaries with dimensions approaching the size of small ions and water molecules. We…
Complete steric exclusion of ions and proton transport through confined monolayer water
K. Gopinadhan, S. Hu, A. Esfandiar +7
It has long been an aspirational goal to create artificial structures that allow fast permeation of water but reject even the smallest hydrated ions, replicating the feat achieved…
Molecular transport through capillaries made with atomic-scale precision
B. Radha, A. Esfandiar, F. C. Wang +13
Nanometre-scale pores and capillaries have long been studied because of their importance in many natural phenomena and their use in numerous applications. A more recent development…
Ballistic molecular transport through two-dimensional channels
A. Keerthi, A. K. Geim, A. Janardanan +8
Gas permeation through nanoscale pores is ubiquitous in nature and plays an important role in a plethora of technologies. Because the pore size is typically smaller than the mean f…
Anomalously low dielectric constant of confined water
L. Fumagalli, A. Esfandiar, R. Fabregas +10
The dielectric constant of interfacial water has been predicted to be smaller than that of bulk water (= 80) because the rotational freedom of water dipoles is expected to decrease…
Long-term memory and synapse-like dynamics in two-dimensional nanofluidic channels
P. Robin, T. Emmerich, A. Ismail +8
Fine-tuned ion transport across nanoscale pores is key to many biological processes such as neurotransmission. Recent advances have enabled the confinement of water and ions to two…
Sieving hydrogen isotopes through two dimensional crystals
M. Lozada-Hidalgo, S. Hu, O. Marshall +6
One-atom-thick crystals are impermeable to atoms and molecules, but hydrogen ions (thermal protons) penetrate through them. We show that monolayers of graphene and boron nitride ca…
Fast water flow through graphene nanocapillaries: a continuum model approach involving the microscopic structure of confined water
M. Neek-Amal, A. Lohrasebi, M. Mousaei +3
Water inside a nanocapillary becomes ordered, resulting in unconventional behavior. A profound enhancement of water flow inside nanometer thin capillaries made of graphene has been…
