This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for medium voltage electrical switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using

Security for IEEE P1451.0-Based IoT Sensor Networks

November 13, 2021
Author(s)
Eugene Song, Kang B. Lee, Ke Zhou, Jun Wu
The challenges of the Internet of Things (IoT) sensor networks include connectivity, interoperability, security, and privacy. The Institute of Electrical and Electronics Engineers (IEEE) P1451.0 standard is being revised based on these challenges and

Spatially Resolved Potential and Li-Ion Distributions Reveal Performance-Limiting Regions in Solid-State Batteries

October 19, 2021
Author(s)
Elliot Fuller, Evgheni Strelcov, Jamie Weaver, Michael Swift, Joshua Sugar, Andrei Kolmakov, Nikolai Zhitenev, Jabez J. McClelland, Yue Qi, Joseph Dura, Alec Talin
The performance of solid-state electrochemical systems is intimately tied to the potential and lithium distributions across electrolyte–electrode junctions that give rise to interface impedance. Here, we combine two operando methods, Kelvin probe force

Metal-Insulator transition in Doped Barium Plumbate

September 16, 2021
Author(s)
Andreza M. Eufrasio, Ian L. Pegg, Nikolaus Deems, Biprodas Dutta, Winnie Wong-Ng, Qingzhen Huang
Solid solutions in the Ba(Pb1−xSrx)O3−z system were prepared by aliovalent substitution of Pb4+ by Sr2+ ions to investigate the effect of cation stoichiometry on thermal and electrical properties as x was varied between 0 and 0.4, in the temperature range

Reference Correlation for the Thermal Conductivity of Ethane-1,2-diol (Ethylene Glycol) from the Triple Point to 475 K and Pressures up to 100 MPa

September 14, 2021
Author(s)
Marko Mebelli, Danai Velliadou, Marc Assael, Konstantinos D. Antoniadis, Marcia L. Huber
We present a new wide-ranging correlation for the thermal of ethane-1,2-diol (ethylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point
