Modeling the apparent and intrinsic viscoelastic relaxation of hydrating cement paste

January 31, 2015
Author(s)
Xiaodan Li, Zachary Grasley, Edward Garboczi, Jeffrey W. Bullard
Finite element procedures combined with microstructure development modeling are integrated to quantitatively predict the viscoelastic/viscoplastic relaxation of cement paste due to intrinsic calcium silicate hydrate viscoelasticity and microstructure

Evaluating smoldering behavior of fire-blocking barrier fabrics

January 29, 2015
Author(s)
Shonali Nazare, William M. Pitts, Szabolcs Matko, Rick D. Davis
This study reports on the smoldering propensity of commercially available barrier fabrics (BFs) in a small-scale mock-up configuration. Most BFs are smolder resistant when tested alone over a standard flexible polyurethane foam (FPUF). However, when

Evaluating Smoldering Behavior of Fire-Blocking Barrier Fabrics

Author(s)
Shonali Nazare, William M. Pitts, Szabolcs Matko, Rick D. Davis
This study reports on the smoldering propensity of commercially available barrier fabrics (BFs) in a small-scale upholstered seating mock-up configuration. Most commercially available BFs are smolder resistant when tested alone over a standard flexible

Metrology Needs for Metal Additive Manufacturing Powders

January 29, 2015
Author(s)
John A. Slotwinski, Edward Garboczi
Additive manufacturing (AM) processes are capable of producing highly complex and customized parts, without the need for dedicated tooling, and can produce parts directly from the part design information. These types of processes are poised to

Probing electric field control of magnetism using ferromagnetic resonance

January 29, 2015
Author(s)
Ziyao Zhou, Morgan Trassin, Ya Gao, Yuan Gao, Diana Qiu, Khalid Ashraf, Tianxiang Nan, Xi Yang, Samuel R. Bowden, Daniel T. Pierce, Mark D. Stiles, John Unguris, Ming Liu, Brandon Howe, Gail Brown, Sayeef Salahuddin, Ramamoorthy Ramesh, Nian Sun
A question of fundamental importance in multiferroic materials, such as BiFeO3, is whether the canted moment arising from the Dzyalozhinski-Moriya coupling is switchable with the application of an electric field. Since this canted moment is weak, directly

Seebeck Coefficient Metrology: Do Contemporary Protocols Measure Up?

January 29, 2015
Author(s)
Joshua B. Martin, Winnie K. Wong-Ng, Martin L. Green
Comparative measurements of the Seebeck coefficient are challenging due to the diversity of instrumentation and measurement protocols. With the implementation of standardized measurement protocols and the use of Standard Reference Materials (SRMs®), for

A Logic Based Network Forensics Model for Evidence Analysis

January 28, 2015
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Many attackers tend to use sophisticated multi-stage and/or multi-host attack techniques and anti-forensic tools to cover their traces. Due to the limitations of current intrusion detection and network forensic analysis tools, reconstructing attack

CALPHAD and the High Entropy Alloy

January 28, 2015
Author(s)
Fan Zhang, Ursula R. Kattner
The name of High Entropy Alloy (HEA) first appeared in the paper by Yeh et al. (Advanced Engineering Materials, 6(5) (2004) 299.) published in 2004. The name was given because the authors found that when five or more components with equal/near equal atomic

Molecular Dynamics of a Model Dimerizing Fluid

January 28, 2015
Author(s)
Christopher E Bertrand, Yun Liu
A model dimer forming fluid has been investigated by continuous molecular dynamics simulations. This study emphasizes the volume fraction and temperature dependence of the static and dynamic properties of the systems, including the structure factor, self

Inducing Ferrimagnetism in Insulating Hollandite Ba 1.2 Mn 8 O 16

January 27, 2015
Author(s)
Amber M. Larson, Pouya Moetakef, Karen Gaskell, Craig Brown, Graham King, Efrain E. Rodriguez
Folded triangular lattices connecting magnetic metal centers can be realized in the so-called hollandite type structure, providing a new platform for multifunctional behavior in transition metal oxides. The microporous oxide BaMn 8O 16 has been tuned from
