Summary Report on NIST Smart Grid Testbeds and Collaborations Workshops

March 3, 2021
Author(s)
Avi Gopstein, Allen R. Goldstein, Dhananjay Anand, Paul A. Boynton
This report captures feedback from two workshops that NIST conducted to determine the challenges and opportunities in the use and design of Smart Grid Testbeds and Collaborations, which were held April 11, 2019, at the University of Tennessee, Knoxville

Tailoring electrode-electrolyte-interfaces in lithium-ion batteries using molecularly engineered functional polymers

February 22, 2021
Author(s)
Laisuo Su, Jamie Weaver, Mitchell C. Groenenboom, Nathan Nakamura, Eric Rus, Priyanka Anand, Shikhar Krishn Jha, Joseph Okasinski, Joseph Dura, B Reeja-Jayan
Electrode−electrolyte interfaces (EEIs) affect the rate capability, cycling stability, and thermal safety of lithium-ion batteries (LIBs). Designing stable EEIs with fast Li+ transport is crucial for developing advanced LIBs. Here, we study Li+ kinetics at

National Institute of Standards and Technology Environmental Scan 2020

Author(s)
Heather Evans, Kristen K. Greene, William M. Healy, Elizabeth Hoffman, Kate Rimmer, Anna V. Sberegaeva, Neil M. Zimmerman
The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses

Solar Cell Performance Measurements Under Artificial Lighting Sources

January 5, 2021
Author(s)
Behrang Hamadani
In recent years, there has been a growing interest in measurements of photovoltaic solar cells under ambient artificial lighting such as light emitting diode (LED) or fluorescent light sources. Certain classes of solar cells are considered very good

Characterization of Long-Term Sub-Hourly Thermal Comfort Performance Data

November 1, 2020
Author(s)
Hyojin Kim, Lisa Ng, Brian P. Dougherty, William V. Payne
Current thermal comfort standards do not provide guidelines on how to graphically characterize and benchmark long-term, sub-hourly, thermal comfort. In an effort to address this void, several statistical characterizations and advanced visualization methods

Crystal Chemistry, X-ray Diffraction Reference Patterns, and Band Gap Studies for (BaxSr1-x)2CoWO6 (x=0.1, 0.2, 0.3, 0.5, 0.7, 0.9)

September 11, 2020
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Yuqi Yang, Rola M. Derbeshi, Donald A. Windover, James A. Kaduk
X-ray reference powder patterns and structures have been determined for a series of cobalt- and tungsten-containing cubic alkaline-earth perovskites, (BaxSr1-x)2CoWO6 (x=0.1, 0.2, 0.3, 0.5, 0.7, 0.9). The structure of the end members of the series

Reversible Room-Temperature Fluoride-Ion Insertion in a Tunnel-Structured Transition Metal Oxide Host

July 6, 2020
Author(s)
Cherno Jaye, Wasif Zaheer, Justin L. Andrews, Forrest P. Hyler, Conan Weiland, David A. Shapiro, Jinghua Guo, Jesus M. Velazquez, Sarbajit Banerjee, Abhishek Parija, Daniel A. Fischer
An energy storage paradigm orthogonal to conventional Li-ion battery chemistries can be conceptualized by employing anions as the primary charge carriers. F-ion conversion chemistries show promise but have limited cyclability as a result of the significant
