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...

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)...

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...

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...

Experimental Study of Firebrand Transport

Author(s)
Samuel L. Manzello, Kuibin Zhou, Sayaka Suzuki
The NIST Firebrand Generator (NIST Dragon) has been used to quantify the vulnerability of structures to ignition by firebrand attack. The Firebrand Generator is...

Absorptive Limiter for Frequency Selective Circuits

Author(s)
Juan C. Collado Gomez, Eduard Rocas, James C. Booth, Jordi Mateu, J. M. O'Callaghan, J. Verdu, A. Hueltes
This paper describes a novel absorptive limiter for frequency selective circuits. The proposed circuit allows the design of absorptive limiters based on a bi...

Low carrier density epitaxial graphene devices on SiC

Author(s)
Yanfei Yang, Lung-I Huang, Yasuhiro Fukuyama, Fan-Hung Liu, Mariano Real, Paola Barbara, Chi-Te Liang, David B. Newell, Randolph Elmquist
Monolayer epitaxial graphene grown on a hexagonal silicon carbide (SiC) substrate is typically found to be heavily n-doped (10e13 cm-2) and in most devices made...

Phase Transitions in K-doped MoO2

Author(s)
L.M.S. Alves, B.S. de Lima, C.A.M. dos Santos, A. Rabello, S.H. Masunaga, J. J. Neumeier, Juscelino Leao
K 0.05MoO 2 has been studied by x-ray and Neutron diffractometry, electrical resistivity, magnetization, heat cpacity, and thermal expansion measurements. The...

Magnetic Ordering induced by Interladder Coupling in the Spin-1/2 Heisenberg Two-leg Ladder Antiferromagnet C9H18N2CuBr4

Author(s)
Tao Hong, K. P. Schmidt, K. Coester, F.F. Awwadi, M.M. Turnbull, Yiming Qiu, Jose Rodriguez Rivera, M. Zhu, X. Ke, C.P. Aoyama, Y. Takano, Huibo Cao, W. Tian, J. Ma, R. Custelcean, H.D. Zhou, M. Matsuda
We present specific-heat and neutron-scattering results for the S=1/2 quantum antiferromagnet (dimethylammonium)(3,5-dimethylpyridinim)CuBr 4. The material...
