Reversible Epitaxial Electrodeposition of Metals in Battery Anodes

November 1, 2019
Author(s)
Jingxu Zheng, Qing Zhao, Tian Tang, Jiefu Yin, Calvin D. Quilty, Genesis D. Renderos, Xiaotun Liu, Yue Deng, Lei Wang, David C. Bock, Cherno Jaye, Esther S. Takeuchi, Kenneth J. Takeuchi, Amy C. Marschilok, Lynden A. Archer
The propensity of metals to form irregular and non-planar electrodeposits at liquid/solid interfaces has emerged as a fundamental barrier to high-energy, rechargeable batteries that utilize metal anodes. We report an epitaxial mechanism to regulate

Transport properties of topologically non-trivial bismuth tellurobromides BinTeBr

September 9, 2019
Author(s)
Falk Pabst, Dean Hobbis, Alzahrani Noha, Hsin Wang, I.P. Rusinov, E.V. Chulkov, Joshua B. Martin, Michael Ruck, George S. Nolas
Temperature dependent transport properties of the recently discovered layered bismuth-rich tellurobromides BinTeBr (n = 2, 3) are investigated for the first time. Dense homogeneous polycrystalline specimens prepared for different electrical and thermal

Major improvement of ferroelectric and optical properties in Na-doped Ruddlesden-Popper layered hybrid improper ferroelectric compound, Ca3Ti2O7

August 20, 2019
Author(s)
Cong Hang, Wei Fang Liu, Winnie Wong-Ng, Ziongnan Zhang, Yao Jiang, Ping Wu, Baoyuan Tong, Hui Zhao, Shouyu Wang
Ruddlesden-Popper layered Ca3-xNaxTi2O7 (x=0 and 0.15) ceramics were successfully prepared by a conventional solid-state reaction process. The polarization and leakage currents were increased after Na doping. XPS spectra showed an increasing concentration

Situational Awareness for Electric Utilities

August 7, 2019
Author(s)
James J. McCarthy, Otis Alexander, Sallie Edwards, Don Faatz, Chris Peloquin, Susan Symington, Andre Thibault, John Wiltberger, Karen Viani
Through direct dialogue between NCCoE staff and members of the energy sector (comprised mainly of electric power companies and those who provide equipment and/or services to them) it became clear that energy companies need to create and maintain a high

Engineered Sulfur-MoS2-Graphene Heterostructure Cathodes for Diagnostics of Nanoscale Electrochemical Processes in High Energy Density Li-S Batteries

August 5, 2019
Author(s)
Vladimir P. Oleshko, William R. McGehee, Saya Takeuchi, Siyuan Zhang, Andrei A. Kolmakov, Jabez J. McClelland, Christopher L. Soles
Lithium-sulfur (Li-S) batteries have recently attracted enormous attention because of high theoretical specific energy (2600 Wh kg-1) and high specific capacity (1672 mAhg-1), as well as the low cost, natural abundance, and nontoxicity of elemental sulfur

Estimating real-time infiltration for use in residential ventilation control

June 18, 2019
Author(s)
Lisa Ng, Stephen M. Zimmerman, Jeremy Good, Brian Tool, Steven Emmerich, Andrew Persily
Minimum outdoor air ventilation rates specified in standards such as ASHRAE Standard 62.2 are generally based on envelope airtightness, building floor area, geographical location, and number of occupants. To meet ventilation requirements in practice

ELECTRON ENERGY-LOSS SPECTROSCOPY AND IMAGING

March 12, 2019
Author(s)
Vladimir P. Oleshko
This article describes electron energy-loss spectroscopy (EELS), energy-filtering transmission electron microscopy (EFTEM) and electron spectroscopic diffraction (ESD) in a transmission electron microscope (TEM) or in a scanning transmission electron

Carbon Capture and Storage Properties of Porous Octahedral Molecular Sieve

March 7, 2019
Author(s)
Matthew Lawson, Jarod C. Horn, Winnie Wong-Ng, Laura Espinal, Huong Giang Nguyen, James A. Kaduk, Saul H. Lapidus, Yongtao Meng, Steven L. Suib, Lan Li
Based on the experimentally determined framework structure of porous MnO2 octahedral molecular sieve (OMS)-5, we used density functional theory-based calculations to evaluate the effect of Na+ cation on pore dimensionality and structural stability, and the

Structural basis of CO2 adsorption in a flexible metal organic framework material

March 4, 2019
Author(s)
Andrew J. Allen, Winnie K. Wong-Ng, Eric J. Cockayne, Jeffrey T. Culp, Christopher Matranga
This paper reports the structural basis of CO2 adsorption in a representative model flexible metal organic framework (MOF) material, Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4] (NiBpene or PICNIC-60). NiBpene exhibits a CO2 sorption isotherm with
