Certification of SRM 2497: Standard Reference Concrete for Rheological Measurements

April 22, 2019
Author(s)
Nicos Martys, Max A. Peltz, William L. George, Blaza Toman, Edward J. Garboczi, Chiara Ferraris
Rotational rheometers are commonly used to determine the rheological properties of fluids such as viscosity and yield stress [Fer12]. Manufacturers generally recommend the use of a standard oil of known viscosity to verify that the instrument is operating

Chip-integrated visible-telecom entangled photon pair source for quantum communication

January 21, 2019
Author(s)
Xiyuan Lu, Qing Li, Daron Westly, Gregory Moille, Anshuman Singh, Vikas Anant, Kartik Srinivasan
Photon pair sources are fundamental blocks for quantum entanglement and quantum communication. Recent studies in silicon photonics have documented promising characteristics for photon pair sources within the telecommunications band, including sub-milliwatt

Energy-level statistics in strongly disordered systems with power-law hopping

July 16, 2018
Author(s)
Paraj T. Bhattacharjee, Victor L. Quito, Sergey V. Syzranov
Motivated by neutral excitations in disordered electronic materials and systems of trapped ultracold particles with long-range interactions, we study energy-level statistics of quasiparticles with the power-law hopping Hamiltonian $\propto 1/r^\alpha$ in a

Synthesis and Synchrotron X-ray characterization of two 2D Hoffman related compounds [Ni(p-Xylylenediamine)nNi(CN)4] and [Ni(p-tetrafluoroxylylenediamine)nNi(CN)4]

April 24, 2018
Author(s)
Winnie K. Wong-Ng, Jeffrey T. Culp, Daniel W. Siderius, Yu-Sheng Chen
Synchrotron X-ray single crystal structure studies of two closed 2D Hofmann-type related compounds, [Ni(p-Xylyenediamine)n-tetracyanonickelate] (abbreviated as Ni-pXdam) and [Ni(tetrafluoro-p-Xylyenediamine)n-tetracyanonickelate] (abbreviated as Ni-pXdamF4

Experimental Investigation of Firebrand Accumulation Zones in Front of Obstacles

December 1, 2017
Author(s)
Samuel L. Manzello, Sayaka Suzuki
It is well accepted that as structures are exposed to wind, stagnation planes are produced around structures. Past work by the authors demonstrated for the first-time that wind-driven firebrand showers may accumulate in these stagnation planes. While those

Quasi-Two-dimensional Phase Transition of Methane Adsorbed in Cylindrical Silica Mesopores

November 29, 2017
Author(s)
Daniel W. Siderius, William P. Krekelberg, Wei-Shan NMN Chiang, Vincent K. Shen, Yun Liu
Using Monte Carlo and molecular dynamics simulations, we examine the adsorption of methane in cylindrical silica mesopores in an effort to understand a possible phase transition of adsorbed methane in MCM-41 and SBA-15 silica that was previously identified

The Effects of Burial Diagenesis on Multiscale Porosity in the St. Peter Sandstone: An Imagine, Small-Angle, and Ultra-Small-Angle Neutron Scattering Analysis

November 4, 2017
Author(s)
Lawrence M. Anovitz, Jared T. Freiburg, Matthew J. Wasbrough, David F. Mildner, Kenneth C. Littrell, Vitaliy Pipich, Jan Ilavsky
To examine the effects of burial diagenesis on heirarchical pore structures in sandstone and compare those with the effects of overgrowth formation, we obtained samples of St. Peter Sandstone from drill cores obtained in the Illinois and Michigan Basins

High-Field Magnetization and Magnetic Phase Diagram of a-Cu 2 V 2 O 7

June 16, 2017
Author(s)
G. Gitgeatpong, M. Suewattana, Shiwei Zhang, A. Miyake, M. Tokunaga, P. Chanlert, N. Kurita, H. Tanaka, T. J. Sato, Yang Zhao, K. Matan
High-field magnetization of the spin-1/2 antiferromagnet α-Cu 2V 2O 7 was measured in pulsed magnetic fields of up to 56 T in order to study its magnetic phase diagram. When the field was applied along the easy axis (the a-axis), two distinct transitions

An Updated Security Analysis of PFLASH

June 4, 2017
Author(s)
Ryann Cartor, Daniel Smith-Tone
One application in post-quantum cryptography that appears especially difficult is security for low-power or no-power devices. One of the early champions in this arena was SFLASH, which was recommended by NESSIE for implementation in smart cards due to its

A Generalized Model of Flame to Surface Heat Feedback for Laminar Wall Flames

March 7, 2017
Author(s)
Isaac T. Leventon, Stanislav I. Stoliarov, Kevin T. Korver
In this work, experimental measurements of flame heat flux and sample mass loss rate are obtained as a flame spreads vertically upward over the surface of seven commonly used polymeric materials, two of which are glass reinforced composites. Using these
