Crystal Chemistry and Phase Equilibria of the CaO- 1/2Ho2O3-CoOz System at 885 degC in Air

July 2, 2020
Author(s)
Winnie K. Wong-Ng, William J. Laws, Qingzhen Huang, Jie Hou, James A. Kaduk, Saul H. Lapidus, Lynn Ribaud
The phase diagram of the CaO-½Ho2O3-CoOz system was determined at 885 ºC in air. This diagram offers detailed compatibility relationships in the ternary oxide system that are essential for processing and for the understanding of thermoelectric properties

Efficient hybrid mixed-ion perovskite photovoltaics: in situ diagnostics of the roles of cesium and potassium alkali cation addition

June 19, 2020
Author(s)
Ming Chun Tang, Yuanyuan Fan, Dounya Barrit, Ruipeng Li, Hoang X. Dang, Siyuan Zhang, Timothy J. Magnanelli, Nhan V. Nguyen, Edwin J. Heilweil, Christina A. Hacker, Detlet-M Smilgies, Kui Zhao, Aram Amassian, Thomas D. Anthopoulos
Perovskite photovoltaics have made extraordinary progress in efficiency and stability in the past few years owing to process and formulation developments like antisolvent drip and mixed-cation mixed-halide compositions. Perovskite solar cells performance

Energy Sector Asset Management: For Electric Utilities, Oil & Gas Industry

May 19, 2020
Author(s)
James J. McCarthy, Lauren Acierto, Jason Kuruvilla, Titilayo Ogunyale, Nikolas Urlaub, John Wiltberger, Devin Wynne
Industrial control systems (ICS) compose a core part of our nation’s critical infrastructure. Energy sector companies rely on ICS to generate, transmit, and distribute power and to drill, produce, refine, and transport oil and natural gas. Given the wide

Kelley, David Sinton, Edward H. Sargent
The carbon dioxide electroreduction reaction (CO2RR) provides avenues to the production renewable ethanol, a high-energy-density fuel. Unfortunately, until now, the ethanol Faradaic efficiency (FE) has lain below 27% in CO2RR studies reported at total

High-Throughput Exploration of Lithium-Alloy Protection Layers for High-Performance Lithium-Metal Batteries

February 13, 2020
Author(s)
Jamie L. Weaver, Kedar Manandhar, Yaoyu Ren, Drew Stasak, Huilong Hou, Dylan Kirsch, Suchismita Sarker, Apurva Mehta, Saydul Sardar, Muye Xiao, Carlos Le?n, Gus Hart, Takeshi Sunaoshi, John Lemmon, Ichiro Takeuchi
To realize high specific capacity Li-metal batteries, a protection layer for the Li-metal anode is needed. We are carrying out combinatorial screening of Li-alloy thin films as the protection layer which can undergo significant lithiation with minimum

Utica Shale Reactivity: CO2 Induced Pore Scale Changes in the Fracture Network and Matrix

January 3, 2020

Angela Goodman, Sean Sanguinito, Sittichai Natesakhawat, Patricia Cvetic, Barbara Kutchko, Andrew J. Allen
The Utica Shale is expected to be a substantial fossil fuel resource in the future. Currently, 663.5 billion cubic feet of natural gas and oil are being produced from the Utica in Eastern Ohio. In this work, we examined the Utica Shale and its reactivity

Structural and Optical Properties of Ba3(Nb6-xTax)Si4O26 (x=0.6, 1.8, 3.0, 4.2, 5.4)

December 5, 2019
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Weifang Liu, Yuqi Yang, Shouyu Wang, Yucheng Lan, James A. Kaduk
Structure and optical properties have been successfully determined for a series of titanium- and cobalt-containing layered alkaline-earth silicate compounds, Ba3(Nb1-xTax)Si4O26 (x=0.6, 1.8, 3.0, 4.2, 5.4). The structure of this solid solution was found to

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
