Equations of State for n-Hexadecane and n-Docosane

August 5, 2022
Author(s)
Raffaela Romeo, Eric W. Lemmon
Equations of state for n-hexadecane (C16H34) and n-docosane (C22H46) have been developed as functions of the Helmholtz energy with independent variables of temperature and density. The equations were developed based on experimental values of density, speed

Microstructure changes during failure of PVDF-based photovoltaic backsheets

July 21, 2022

The structure, powder diffraction patterns and band gap measurements of a series of manganese- and tungsten-containing alkaline-earth double perovskites (CaxSr2-x)MnWO6 (x=0.25, 0.5, 0.75, 1.5, 1.75) have been investigated. Powder X-ray diffraction

Two TE market approaches and impact on grid and customer flexibility

April 27, 2022
Author(s)
David Holmberg
This presentation covers simulation research evaluating two approaches to communicating value of electricity to customers. The first communicates day ahead prices to customers and allows customers to purchase forecast load at those prices with actual

Multimodal X-ray Probing of the Capacity Fade Mechanisms of Nickel Rich NMC - Progress and Outlook

April 22, 2022
Author(s)
Cherno Jaye, Daniel A. Fischer, Calvin Quilty, Patrick West, Wenzao Li, Mikaela Dunkin, Garrett Wheeler, Steven Ehrlich, Lu Ma, Esther Takeuchi, Kenneth Takeuchi, David Bock, Amy Marschilok
NMC is a commercially successful Li-ion battery cathode due to its high energy density; however, its delivered capacity must be intentionally limited to achieve capacity retention over extended cycling. To design next-generation NMC batteries with longer

Potentiometric Rotating Ring Disk Electrode (RRDE) Study of Interfacial pH during CO2 Reduction and H2 Generation in Neutral and Weakly Acidic Media

April 21, 2022
Author(s)
Thomas P. Moffat, Nicole Ritzert, David Raciti, Brian Tackett, Nicholas Brady
Electrocatalytic reduction of CO2 to CO in aqueous media offers an important path to more sustainable carbon utilization. Optimization of this process relies on a detailed understanding of the dynamics of boundary layer chemistry, e.g., pH, adjacent to the

Improved capacity and reversibility of solid-state Li-O2 battery through water-vapour-assisted cathode reaction

April 8, 2022
Author(s)
Cherno Jaye, Daniel A. Fischer, Mokwon Kim, Hyunpyo Lee, Hyuk Jae Kwon, Seong-Min Bak, Gabin Lee, Jung O. Park, Dong-Hwa Seo, Song Bok Ma, Dongmin Im
The development of a cathode for solid-state lithium-oxygen batteries has been hindered in practice by a low capacity and limited cycle life despite their potential for high energy density. Here, a previously unexplored strategy is proposed wherein the

New International Formulation for the Thermal Conductivity of Heavy Water

March 9, 2022
Author(s)
Marcia L. Huber, Richard A. Perkins, Marc Assael, Stella Monogenidou, Robert Hellmann, Jan Sengers
The International Association for the Properties of Water and Steam (IAPWS) has adopted a new formulation for the thermodynamic properties of heavy water. This manuscript describes the development of a new correlation for the thermal conductivity of heavy

Nanoscale Photoexcited Carrier Dynamics in Perovskites

Samuel Berweger, Fei Zhang, Bryon Larson, Andrew Ferguson, Axel Palmstrom, Obadiah Reid, Thomas Mitchell (Mitch) Wallis, Kai Zhu, Joseph Berry, Pavel Kabos, Sanjini Nanayakkara
The excellent optoelectronic properties of lead-halide perovskite thin films are complemented by their tolerance to broad compositional variations and associated strain, which allows tuning of desired properties such as the optical bandgap. On the other

Color-Temperature Dependence of Indoor Organic Photovoltaic Performance

March 5, 2022

Boya Zhang, Justin Bonner, Lakshmi Murthy, Thien Nguyen, Fong-Yi Cao, Yen-Ju Cheng, Behrang Hamadani, Julia Hsu
Organic materials are uniquely suited for indoor light energy harvesting because they absorb mostly in the visible spectrum and the absence of ultraviolet light minimizes their degradation. However, the performance of photovoltaic devices under indoor

Elucidating Cathode Degradation Mechanisms in NMC811/Graphite Cells Under Fast Charge Rates Using Operando Synchrotron Characterization
