Flux growth of Yb6.6Ir6Sn16 having mixed valent ytterbium

Author(s)
Sebastian Peter, Udumula Subbarao, Sudhindra Rayaprol, Joshua Martin, Mahalingam Balasubramanian, Christos D. Malliakas, Mercouri G. Kanatzidis
The new compound Yb6.6Ir6Sn16 was obtained as single crystals in high yield from the reaction of Yb with Ir and Sn run in excess indium. Single crystal X-ray...

Morphological origin of charge transport anisotropy in aligned polythiophene thin films

Author(s)
Brendan T. O'Connor, Obadiah G. Reid, Xinran Zhang, Regis J. Kline, Lee J. Richter, David J. Gundlach, Dean DeLongchamp, Michael F. Toney, Nikos Kopidakis, Garry Rumbles
The morphological origin of anisotropic charge transport in uniaxially strain aligned poly(3-hexylthiophene) (P3HT) films is investigated. The macroscale field...

A study of shear banding in polymer solutions

Author(s)
Michael E. Cromer, Glenn Fredrickson, Gary Leal
In a recent letter (Cromer et al. Phys. Fluids 2013) we showed, for the first time, the existence of a steady shear-banded velocity profile for a polymer...

Quantifying Crystallinity in High Molar Mass Poly(3-hexylthiophene)

Author(s)
Chad R. Snyder, Ryan C. Nieuwendaal, Dean M. DeLongchamp, Christine K. Luscombe, Prakash Sista, Shane D. Boyd
We extend a recent comprehensive study of 3-hexylthiophene oligomers to high molar mass poly(3-hexylthiophene) (P3HT) fractions, such as those used in organic...

Algorithmic Framework for Quality Assessment of Phase Equilibrium Data

Author(s)
Vladimir Diky, Robert D. Chirico, Joe W. Magee, Chris D. Muzny, Andrei F. Kazakov, Kenneth G. Kroenlein, Michael D. Frenkel, Jeongwon J. Kang
Data quality assessment procedures for various types of phase equilibrium data are reviewed and analyzed. Experimental data for vapor-liquid equilibrium (VLE)...

BPMN Profile for Operational Requirements

Author(s)
Conrad E. Bock, Raphael Barbau, Anantha Narayanan Narayanan
An important aspect of systems and products is how they interact with their environment, including how they are operated. Behaviors external to systems usually...
