Thermodynamic Interactions and Phase Behavior of Multicomponent Blends Containing Supercritical Carbon Dioxide, Styrene-Acrylonitrile Random Copolymer, and Deuterated Poly(methyl methacrylate)

November 7, 2014
Author(s)
Nicholas P. Young, Sebnem Inceoglu, Gregory M. Stone, Andrew J. Jackson, Steven R. Kline, Stephane Costeux, Nitash P. Balsara
Small-angle neutron scattering (SANS) was used to probe the phase behavior of multicomponent mixtures of supercritical carbon dioxide (scCO 2), styrene-acrylonitrile random copolymer, and deuterated poly(methacrylate). Homogeneous ternary mixtures phase

Aqueous Solubilization of Hydrophobic Supramolecular Metal-Organic Nanocapsules

June 1, 2014
Author(s)
Harshita Kumari, Steven R. Kline, Jerry L. Atwood
Micelles of metal-seamed C-alkylpyrogallol[4]arene-based (PgC nM) hexamers and dimers in water have been formulated and characterized using in situ scattering techniques. The aqueous solubilization of these hydrophobic nanocapsules is facilitated by the

Effect of Supercritical Carbon Dioxide on the Thermodynamics of Model Styrene-Acrylonitrile Copolymer-Poly(methyl methacrylate) Blends Studied by Small-Angle Neutron Scattering

July 25, 2013
Author(s)
Sebnem Inceoglu, Nicholas P. Young, Andrew J. Jackson, Steven Kline, Stephane Costeux, Nitash P. Balsara
Small-angle neutron scattering was used to study a binary blend of styrene-acrylonitrile copolymer (SAN) and deuterated poly(methyl methacrylate) (dPMMA), as wellas a multicomponent mixture of SAN, dPMMA, and supercritical carbon dioxide (scSO 2). The

Chemically Modifiable Fluorinated Copolymer Nanoparticles for 19F MRI Contrast Enhancement

December 27, 2012
Author(s)
Jessica L. Staymates, Mark M. Bailey, Steven R. Kline, Michael D. Anderson, Cory Berkland
Recently there has been interest in developing imaging contrast media for magnetic resonance imaging (MRI) that contain biologically rare, magnetically active nuclei such as fluorine. In principle, fluorinated contrast agents can be used to generate highly

Solution-phase and Magnetic Approach Towards Understanding Iron Gall Inks

August 13, 2012
Author(s)
Harshita Kumari, Steven R. Kline, Cindi L. Dennis, Andrew V. Mossine, Rick L. Paul, Carol A. Deakyne, Jerry L. Atwood
Crystallization of compounds of iron with polyphenols, such as iron gall inks, has been an ongoing challenge. As with iron-gall inks, iron complexes of 1,2,3-trihydroxphenol-containing marocycles have also proved difficult to crystallize. Despite this

Controlling the Self-Assembly of Metal-Seamed Organic Nanocapsules

January 3, 2012
Author(s)
Harshita Kumari, Andrew V. Mossine, Steven R. Kline, Cindi L. Dennis, Drew A. Fowler, Simon J. Teat, Charles L. Barnes, Carol A. Deakyne, Jerry L. Atwood
Puzzling out the intricacies associated with formation of supramolecular structures provides insight into and control of the self-assembly process. Such control may allow tailoring of these structures for specific applications. Herein we report the results
