Stochastic transport through carbon nanotubes in lipid bilayers and live cell membranes
Jia Geng,Kyunghoon Kim,Jianfei Zhang,Artur Escalada,Ramya H. Tunuguntla,Luis R. Comolli,Frances I. Allen,Anna V. Shnyrova,Kang Rae Cho,Dayannara Munoz,Y. Morris Wang,Costas P. Grigoropoulos,Caroline M. Ajo-Franklin,Vadim A. Frolov,Aleksandr Noy +14 more
TL;DR: It is shown that short CNTs spontaneously insert into lipid bilayers and live cell membranes to form channels that exhibit a unitary conductance of 70–100 picosiemens under physiological conditions, thereby establishing these nanopores as a promising biomimetic platform for developing cell interfaces, studying transport in biological channels, and creating stochastic sensors.
Journal ArticleDOI
Ultrafast proton transport in sub-1-nm diameter carbon nanotube porins
TL;DR: The results illustrate the potential of small-diameter carbon nanotube porins as a proton conductor material and suggest that strong spatial confinement is a key factor in enabling efficient proton transport.
Journal ArticleDOI
Self-Assembly and Transport Limitations in Confined Nafion Films
Miguel A. Modestino,Miguel A. Modestino,Devproshad K. Paul,Shudipto K. Dishari,Stephanie A. Petrina,Frances I. Allen,Michael A. Hickner,Kunal Karan,Kunal Karan,Rachel A. Segalman,Rachel A. Segalman,Adam Z. Weber +11 more
TL;DR: In this article, a combination of transport-property measurements and structural characterization is used to demonstrate that confinement of Nafion in thin films induced thickness-dependent proton conductivity and ionic-domain structure.
Journal ArticleDOI
Morphology of Hydrated As-Cast Nafion Revealed through Cryo Electron Tomography
Frances I. Allen,Frances I. Allen,Luis R. Comolli,Luis R. Comolli,Ahmet Kusoglu,Ahmet Kusoglu,Miguel A. Modestino,Miguel A. Modestino,Andrew M. Minor,Andrew M. Minor,Adam Z. Weber,Adam Z. Weber +11 more
TL;DR: In this article, a nanoscale study of dry versus hydrated as-cast 100 nm Nafion membranes using analytical transmission electron microscopy (TEM) and cryogenic TEM tomography, respectively, is presented.
Journal ArticleDOI
Synthesis of hierarchical TiO2 nanowires with densely-packed and omnidirectional branches
Daeho Lee,Yoonsoo Rho,Frances I. Allen,Frances I. Allen,Andrew M. Minor,Andrew M. Minor,Seung Hwan Ko,Seung Hwan Ko,Costas P. Grigoropoulos +8 more
TL;DR: A parametric study of the DSSC efficiency showed that branched TiO2 DSSCs can achieve nearly four times the efficiency of non-branchedTiO2 nanowire D SSCs, and up to 170% the efficiency
