Jain T, Rasera B, Guerrero R, Boutilier M, OHern S, Idrobo J, et al.
Nat Nanotechnol
. 2015 Oct;
10(12):1053-7.
PMID: 26436566
Graphene and other two-dimensional materials offer a new class of ultrathin membranes that can have atomically defined nanopores with diameters approaching those of hydrated ions. These nanopores have the smallest...

OHern S, Jang D, Bose S, Idrobo J, Song Y, Laoui T, et al.
Nano Lett
. 2015 Apr;
15(5):3254-60.
PMID: 25915708
Monolayer nanoporous graphene represents an ideal membrane for molecular separations, but its practical realization is impeded by leakage through defects in the ultrathin graphene. Here, we report a multiscale leakage-sealing...

OHern S, Boutilier M, Idrobo J, Song Y, Kong J, Laoui T, et al.
Nano Lett
. 2014 Feb;
14(3):1234-41.
PMID: 24490698
We report selective ionic transport through controlled, high-density, subnanometer diameter pores in macroscopic single-layer graphene membranes. Isolated, reactive defects were first introduced into the graphene lattice through ion bombardment and...

ACS Nano
. 2014 Jan;
8(1):841-9.
PMID: 24397398
Gas transport through intrinsic defects and tears is a critical yet poorly understood phenomenon in graphene membranes for gas separation. We report that independent stacking of graphene layers on a...

ACS Nano
. 2012 Oct;
6(11):10130-8.
PMID: 23030691
We report graphene composite membranes with nominal areas more than 25 mm(2) fabricated by transfer of a single layer of CVD graphene onto a porous polycarbonate substrate. A combination of...
