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

The Effect of Gravity on the Resolution of Small-Angle Neutron Diffraction Peaks

October 1, 2011
Author(s)
David F. Mildner, John G. Barker, Steven R. Kline
The resolution ellipses for neutron diffraction peaks at small vectors lie along lines that point to a position vertically above the beam center. This gravity effect is only noticeable for neutron beams at long wavelenghts and with large wavelength spreads

Formation of Kinetically Trapped Nanoscopic Unilamellar Vesicles from Metastable Nanodiscs

September 27, 2011
Author(s)
Mu-Ping Nieh, Paul Dolinar, Norbert Kucerka, Steven R. Kline, Lisa M. Debeer-Schmitt, Kenneth C. Littrell, John Katsaras
Zwitterionic long-chain lipids form onion-like structures, commonly known as multilamellar vesicles (MLVs), in aqueous solution. It is also known that the addition of short-chain lipids and charged long-chain lipids to zwitterionic longchain lipids leads

Ferrocene as a Hydrophobic Templating Agent with Pyrogallol[4]arenes

July 11, 2011
Author(s)
Andrew V. Mossine, Harshita Kumari, Drew A. Fowler, Andrew K. Maerz, Steven R. Kline, Charles L. Barnes, Jerry L. Atwood
Cocrystallization of C-methylpyrogallol[4]arene (PgC1) and ferrocene in a methanolic solution led to the formation of two distinct crystalline products featuring two substantially different host-guest environs . The first of these features an exclusively
