Journal ArticleDOI
Spontaneous Partition of Carbon Nanotubes in Polymer-Modified Aqueous Phases
TL;DR: A general rule governing CNT behaviors in aqueous phase is revealed and an extremely simple way to achieve spatial separation of CNTs by their electronic structures is provided.
Journal ArticleDOI
Comparison of the quality of aqueous dispersions of single wall carbon nanotubes using surfactants and biomolecules.
Reto Haggenmueller,Sameer S. Rahatekar,Jeffrey A. Fagan,Jaehun Chun,Matthew L. Becker,Rajesh R. Naik,Todd D. Krauss,Lisa J. Carlson,John F. Kadla,Paul C. Trulove,Douglas F. Fox,Hugh C. DeLong,Zhichao Fang,Shana O. Kelley,Jeffrey W. Gilman +14 more
TL;DR: A quantitative comparison of the relative ability of "wrapping polymers" including oligonucleotides, peptides, lignin, chitosan, and cellulose and surfactants such as cholates, ionic liquids, and organosulfates to disperse SWCNTs in water is reported.
Journal ArticleDOI
Isolation of specific small-diameter single-wall carbon nanotube species via aqueous two-phase extraction.
Jeffrey A. Fagan,Constantine Y. Khripin,Carlos A. Silvera Batista,Jeffrey R. Simpson,Erik H. Haroz,Angela R. Hight Walker,Ming Zheng +6 more
TL;DR: Aqueous two-phase extraction is demonstrated in this article to enable isolation of single semiconducting and metallic single-wall carbon nanotube species from a synthetic mixture, with remarkable tunability via modification of the surfactant environment set for the separation.

Isolation of Specific Small Diameter Single-Wall Carbon Nanotube Species via Aqueous Two-Phase Extraction
Jeffrey A. Fagan,Constantine Y. Khripin,Carlos A. Silvera Batista,Jeffrey R. Simpson,Angela R. Hight Walker,Ming Zheng +5 more
TL;DR: Aqueous two-phase extraction is demonstrated to enable isolation of single semiconducting and metallic single-wall carbon nanotube species from a synthetic mixture with remarkable tunability via modification of the surfactant environment set for the separation.
Journal ArticleDOI
Length fractionation of carbon nanotubes using centrifugation
TL;DR: In this article, the authors demonstrated the use of ultracentrifugation on single wall carbon nanotubes (SWCNTs) within a density gradient to produce a more facile and scalable, chirality separation.
