April 24, 2018
Author(s)
Hui-Min Wen, Bin Li, Libo Li, Rui-Biao Lin, Wei Zhou, Guodong Qian, Banglin Chen
Extensive research has been devoted to develop new porous materials for high methane storage capacity. While great progress has been made in recent years, it still remains very challenging to target simultaneously high gravimetric and volumetric methane

Calibration of mobile manipulators using 2D positional features

April 24, 2018
Author(s)
Mili Shah, Roger V. Bostelman, Steven Legowik, Tsai H. Hong
Robotic manipulators are increasingly being attached to Automatic Ground Vehicles (AGVs) to aid in the effi-ciency of assembly for manufacturing systems. However, calibrating these mobile manipulators is difficult as the offset between the robotic manipulator

Cloud Computing Service Metrics Description

Author(s)
Frederic J. de Vaulx, Eric D. Simmon, Robert B. Bohn
With cloud computing in the mainstream, there is a preponderance of cloud based services in the market and the choices for consumers increase daily. However, comparing the service offerings between cloud service providers is not a straightforward exercise

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

Evaluating Predictors of Congestion Collapse in Communication Networks

April 23, 2018
Author(s)
Christopher E. Dabrowski, Kevin L. Mills
Researchers model congestion in communication networks using a percolation process, where congestion spreads minimally before a critical load and expands rapidly afterwards. Some studies identify precursor signals arising near critical load, but none

How measurement science can improve confidence in research results

April 23, 2018
Author(s)
Anne L. Plant, Chandler A. Becker, Robert J. Hanisch, Ronald F. Boisvert, Antonio M. Possolo, John T. Elliott
The concepts and methods of measurement science can help provide clarity in the definition of reproducibility and its role in the scientific process. The qualities of rigorous research include reproducibility as one component, but there are other important

Measured In-situ Mass Absorption Spectra for Nine Forms of Highly-absorbing Carbonaceous Aerosol

April 23, 2018
Author(s)
Christopher D. Zangmeister, Rian You, Elizabeth M. Lunny, Arne Jacobson, Mitchio Okumura, Michael R. Zachariah, James G. Radney
Mass absorption coefficient spectra were measured between λ = 500 nm and 840 nm for nine forms of highly-absorbing carbonaceous aerosol: five samples generated from gas-, liquid- and solid- fueled flames; spark-discharge fullerene soot; graphene and

Using Temperature to Reduce Noise in Quantum Frequency Conversion

April 23, 2018
Author(s)
Paulina S. Kuo, Jason S. Pelc, Carsten Langrock, M. M. Fejer
Quantum frequency conversion (QFC) is important in quantum networks to interface nodes operating at different wavelengths and to enable long-distance quantum communication using telecommunications wavelengths. Unfortunately, frequency conversion in actual

Adsorption of Polysorbate 20 and Proteins on Hydrophobic Polystyrene Surfaces Studied by Neutron Reflectometry

April 21, 2018
Author(s)
Zhenhuan NMN Zhang, Sara V. Orski, Ann Marie Woys, Guangcui Yuan, Isidro E. Zarraga, Norman J. Wagner, Yun Liu
Understanding adsorption of protein and surfactant to hydrophobic surfaces is key for storage stability and delivery of pharmaceutical liquid formulations, because many commonly-used devices, such as drug containers and syringes, have product-containing
