Influence of Hydrocarbon Moiety of DMMP on Flame Propagation in Lean Mixtures

July 7, 2016
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Viswanath R. Katta, Fumiaki Takahashi
Phosphorus-containing compounds (PCCs) have been found to be significantly more effective than CF3Br for reducing burning velocity when added to stoichiometric hydrocarbon-air flames. However, when added to lean flames, DMMP (dimethylmethylphosphonate) is

Interconversion of Peptide Mass Spectral Libraries Derivatized with iTRAQ or TMT Labels

July 7, 2016
Author(s)
Zheng Zhang, Xiaoyu Yang, Yuri A. Mirokhin, Dmitrii V. Tchekhovskoi, Weihua Ji, Sanford P. Markey, Pedatsur Neta, Bowen A. Michael, Stephen E. Stein
Derivatizing peptides with isobaric tags such as iTRAQ and TMT is widely employed in proteomics due to their ability to multiplex quantitative measurements. We recently made publicly available a large peptide library derived from iTRAQ 4-plex labeled

Local coexistence of VO2 phases revealed by deep data analysis

July 7, 2016
Author(s)
Evgheni Strelcov, Anton Ievlev, Alex Belianinov, Alexander Tselev, Andrei A. Kolmakov, Sergei Kalinin
We report a synergistic approach of micro-Raman spectroscopic mapping and deep data analysis to study the distribution of crystallographic phases and ferroelastic domains in a defected Al-doped VO2 microcrystal. Bayesian linear unmixing revealed an uneven

An Informatics Infrastructure for the Materials Genome Initiative

July 6, 2016
Author(s)
Alden A. Dima, Sunil K. Bhaskarla, Chandler A. Becker, Mary C. Brady, Carelyn E. Campbell, Philippe J. Dessauw, Robert J. Hanisch, Ursula R. Kattner, Kenneth G. Kroenlein, Adele P. Peskin, Raymond L. Plante, Guillaume Sousa Amaral, Zachary T. Trautt, James A. Warren, Sharief S. Youssef, Sheng Yen Li, Pierre Francois Rigodiat, Marcus W. Newrock
A materials data infrastructure that enables the sharing and transformation of a wide range of materials data is an essential part of achieving the goals of the Materials Genome Initiative. We describe two high-level requirements of such an infrastructure

Rheology of clustering protein solutions

July 5, 2016
Author(s)
Vishnu Dharmaraj, P. Douglas Godfrin, Yun Liu, Steven Hudson
High viscosity is a major challenge with protein therapeutics at extremely high concentration. Understanding the relationship between the concentration of a protein solution and its viscosity as a function of shear rate and temperature is therefore

How to Evaluate Ventilation in IAQ Studies

July 4, 2016
Author(s)
Andrew Persily, Paul Wargocki
Currently, many indoor air quality studies fail to adequately describe ventilation in the space or building being studied. In other cases, ventilation rates are provided with limited or no descriptions of how the measurements were made or no estimates of

Pros and Cons of Egress Drills

July 4, 2016
Author(s)
Steve Gwynne, Karen E. Boyce, Erica D. Kuligowski, Daniel Nilsson, Amanda Robbins, Ruggiero Lovreglio
This article explores how egress drills are currently employed, their impact, and the insights gained from them. By investigating their strengths and limitations, this article suggests opportunities for enhancement through the use of other egress models to

Implementing the ISO 15746 Standard for Chemical Process Optimization

July 3, 2016
Author(s)
Guodong Shao, Peter O. Denno, Albert T. Jones, Yan Lu
Integrating advanced process control solutions with optimization (APC-O) solutions, within any factory, enables more efficient production processes. Currently, vendors who provide the software applications that implement control solutions are isolated and

Addressing Pressing Cybersecurity Issues through Collaboration

July 1, 2016
Author(s)
William J. Fisher
The National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology addresses businesses’ most pressing cybersecurity problems with practical, standards-based solutions using commercially available technologies

Certification Report for the Reference Materials ERM-AE142 and ERM-EB400 A pure Pb solution and a bronze material, both certified for their Pb isotope amount ratios

July 1, 2016
Author(s)
Jochen Vogl, Dorit Becker, Maren Koenig, Yong-Hyeon Yim, Kyoung-Seok Lee, Heidi Goenaga-Infante, Dmitriy Malinowskiy, Sarah Hill, Tongxiang Ren, Jun Wang, Robert D. Vocke Jr., Karen E. Murphy, Naoko Nonose, Olaf Rienitz, Janine Noordmann
Lead isotope analysis is often applied in various fields such as archaeology, geochemistry and forensic science. Despite this, only the 3 primary isotopic reference materials NIST SRM; 981, NIST SRM 982 and NIST SRM 983 are available, whereby NIST SRM 981

Data Acquisition and Analysis Software for Gamma Coincidence Spectrometry

July 1, 2016
Author(s)
Martin Girchis Shetty, Dagistan Sahin
Coincidence counting in neutron activation analysis has well-known advantages, such as enhancement of signal and reduction in background. One obstacle to the wider use of this technique is the complexity of the data acquisition and reduction systems that

Dimensional Measurement Uncertainty from Data. Part 2: Uncertainty R&R

July 1, 2016
Author(s)
Theodore D. Doiron
While check standards will eventually give the most accurate uncertainty for a calibration procedure, the time and expense can be discouraging. Another common method, standard Gage Repeatability and Reproducibility study does not produce anything like the

Direct time-domain observation of attosecond final-state lifetimes in photoemission from solids

July 1, 2016
Author(s)
Zhensheng Tao, Cong Chen, Tibor Szilvasi, Mark W. Keller, Manos Mavrikakis, Henry C. Kapteyn, Margaret M. Murnane
Attosecond spectroscopic techniques have made it possible to measure differences in transport times for photoelectrons from localized core levels and delocalized valence bands in solids. We report the application of attosecond pulse trains to directly and

Electron Enhanced Growth of Crystalline Gallium Nitride Thin Films at Room Temperature and 100 C Using Sequential Surface Reactions

July 1, 2016
Author(s)
Alexana Roshko, Jaclyn Sprenger, Andrew S. Cavanagh, Steven George, Huaxing Sun, Kathryn J. Wahl
Low energy electrons may provide mechanisms to enhance thin film growth at low temperatures. In this work, gallium nitride (GaN) films were deposited over areas of ~5 cm2 at room temperature and 100 C using electrons with a low energy of 50 eV from an
