Journal ArticleDOI
Electrospinning of chitin nanofibers directly from an ionic liquid extract of shrimp shells
TL;DR: High molecular weight chitin fibers were electrospun in a one-pot process directly from a 1-ethyl-3-methylimidazolium acetate solution of chitIn extracted from dried shrimp shell to obviate the need for the many chemicals and the energy used in industrial isolation of Chitin from crustacean shells.
Journal ArticleDOI
Surface modification of ionic liquid-spun chitin fibers for the extraction of uranium from seawater: seeking the strength of chitin and the chemical functionality of chitosan
Patrick S. Barber,Steven P. Kelley,Chris S. Griggs,Chris S. Griggs,Sergei Wallace,Robin D. Rogers +5 more
TL;DR: Overall, a platform has been developed for the surface modification of chitin fibers that provides both the physical properties ofChitin and the functional properties of Chitosan, resulting in an advanced material from a biorenewable resource with reduced chemical input.
Journal ArticleDOI
Coagulation of chitin and cellulose from 1-ethyl-3-methylimidazolium acetate ionic-liquid solutions using carbon dioxide.
Patrick S. Barber,Chris S. Griggs,Chris S. Griggs,Gabriela Gurau,Zhen Liu,Shan Li,Zengxi Li,Xingmei Lu,Suojiang Zhang,Robin D. Rogers,Robin D. Rogers +10 more
TL;DR: The use of CO2 chemisorption as an alternative coagulating process has the potential to provide an economical and energy-efficient method for recycling the ionic liquid.
Journal ArticleDOI
Pulping of Crustacean Waste Using Ionic Liquids: To Extract or Not To Extract
Julia L. Shamshina,Julia L. Shamshina,Patrick S. Barber,Gabriela Gurau,Chris S. Griggs,Robin D. Rogers,Robin D. Rogers +6 more
TL;DR: Compared to a previously reported IL extraction using 1-ethyl-3-methylimidazolium acetate, [C2mim][OAc], these less expensive ILs can achieve comparable chitin yields and purity, at up to ten times the biomass loading, although potentially result in lower molecular weight chitIn.
Journal ArticleDOI
Graphene and Graphene Oxide Can “Lubricate” Ionic Liquids based on Specific Surface Interactions Leading to Improved Low-Temperature Hypergolic Performance†
Parker D. McCrary,Preston A. Beasley,Spencer A. Alaniz,Chris S. Griggs,Rachel M. Frazier,Robin D. Rogers +5 more
TL;DR: Graphene and graphene oxide (r-GO) can strongly improve the low-temperature performance of hypergolic ionic liquids by reduction of viscosity by match the graphene type to the specific ionic-liquid functionality.
