Applying Retail Markets and Transactive Resources for Grid Flexibility

September 28, 2026
Author(s)
David Holmberg, William Cox, Toby Considine
The electric grid faces strain driven by rapidly growing loads (for example, data centers, onshoring, and electrification), retiring dispatchable generation, and increasing intermittent renewables. Traditional utility mechanisms for managing customer

Reference Correlation of the Thermal Conductivity of Neon

June 30, 2026
Author(s)
Marc Assael, Sofia Sotiriadou, Monika Thol, Marcia Huber
A new wide-ranging correlation for the thermal conductivity of neon, based on the most recent ab-initio dilute gas theoretical calculations, a simplified crossover critical enhancement contribution, and critically evaluated experimental data, is presented

Origin of the voltage gap and recombination losses in all-perovskite tandem solar cells

March 19, 2026
Author(s)
Hurriyet Yuce Cakir, John Roller, Haoran Chen, Tingting Zhu, Susanna Thon, Yanfa Yan, Zhaoning Song, Behrang Hamadani
All-perovskite tandem solar cells with narrow and wide bandgap perovskite absorbers are promising candidates for low-cost and high efficiency photovoltaic applications. However, the open circuit voltage of typical tandem structures is generally smaller

Comparison of Electroluminescence and Photoluminescence Imaging of Mixed-Cation Mixed-Halide Perovskite Solar Cells at Low Temperatures

February 16, 2026
Author(s)
Hurriyet Yuce Cakir, Haoran Chen, Isaac Ogunniranye, Susanna Thon, Yanfa Yan, Zhaoning Song, Behrang Hamadani
Mixed-cation mixed-halide perovskites have emerged as promising candidates for high-performance solar cells. This study investigates the temperature-dependent optoelectronic properties of Rb0.05Cs0.05MA0.05FA0.85Pb(I0.95Br0.05)3 perovskite solar cells

The Strategic Role of 2D Nanomaterials in Grid Modernization

January 16, 2026
Author(s)
Matthew Glasscott, James Burgess, Peter Byrley, Maria Fernanda Campa, Mark Griep, Alexander Kirk, Stephanie Mack, Birgit Schwenzer, Ryan Welch, Elisabeth Mansfield
Two-dimensional (2D) nanomaterials are poised to catalyze the modernization of today's electrical grid into the Resilient Smart Grid (RSG) of the future. This Perspective explores the role of existing and projected 2D nanomaterial-enabled technologies in

Reference Correlation of the Viscosity of Argon

July 10, 2025
Author(s)
Sofia Sotiriadou, Konstantinos Antoniadis, Marc Assael, Marcia Huber
This paper presents a new wide-ranging reference correlation for the viscosity of argon, incorporating recent ab initio dilute gas calculations and critically evaluated experimental data. The correlation is designed to be used with a high-accuracy

Elucidating the thermal properties and anomalous transport in the 18R polytype of SnSe2

May 30, 2025
Author(s)
Oluwagbemiga Ojo, Wilarachchige D. C. B. Gunatilleke, Winnie Wong-Ng, Tieyan Chang, Yu-Sheng Chen, Joshua Martin, Adam Biacchi, George Nolas
The 18R polytype of SnSe2 possesses unique structural features that can directly impact the transport properties and potential applications of interest; however, a comprehensive understanding of the intrinsic physical properties is lacking. We grew large

Electrolytes that reduce electro-osmotic drag improve fast charging of lithium-ion batteries

May 13, 2025
Author(s)
Chang-Xin Zhao, Zeyi Wang, David Jacobson, Yue Li, Boris Khaykovich, Sean Fayfar, Jacob LaManna, Daniel Hussey, Lei Zheng, Gabriel Veith, Fu Chen, Chunsheng Wang
Fast charging (at rates greater than 4 C) is essential for high-energy lithium-ion batteries in electric vehicles yet remains challenging owing to a lack of understanding of fast-charging barriers. Conventional optimization strategies concentrate on

Tuning the Surface Electronic Landscape of Ultrathin (Al,Sn)Ox Electron Extraction Layers in Perovskite Solar Cells

April 10, 2025
Author(s)
Joshua Sraku Adu, Alice Sheppard, Raphael Agbenyeke, George Kwesi "Asare ", Behrang Hamadani, David Fermin, Helen Hejin Park
Power conversion losses at the electron transport layer (ETL) are key limiting factors in high-performance perovskite solar cells (PSC) and silicon-PSC tandem systems. Solution-processed nanoparticle tin dioxide (np-SnO2) films typically serve as ETLs in n

Impacts of household water demands and water heater delivery temperatures on opportunistic premise plumbing pathogens (OPPPs) in a residential setting

February 1, 2025
Author(s)
Alshae Logan, Jumana Aljafari, Visesh Uppoor, Tania Ullah, Jennifer Dootz
Efforts aimed towards water and energy conservation within residential buildings may create enhanced conditions for Opportunistic Premise Plumbing Pathogens (OPPPs) growth. To investigate this issue, a study was conducted to assess the effect of water

A Helmholtz Energy Equation of State for 3,3,3-Trifluoroprop-1-ene (R-1243zf)

January 15, 2025
Author(s)
Ryo Akasaka, Eric Lemmon
A new fundamental equation of state expressed as a function of the Helmholtz energy is presented for 3,3,3-trifluoroprop-1-ene (R-1243zf). The equation is valid from the triple point temperature (122.35 K) to 430 K at pressures up to 35 MPa. The expected

PVDF-based Backsheet Cracking: Mapping In Situ Phase Evolution by X-ray Scattering

December 15, 2024
Author(s)
Stephanie Moffitt, Sona Ulicna, Song-Syun Jhang, Po-Chang Pan, Michael Owen-Bellini, Peter Hacke, Michael Kempe, Jared Tracy, Kaushik Choudhury, Laura Schelhas, Xiaohong Gu
One of the most common polymers in commercial photovoltaic (PV) backsheets is polyvinylidene fluoride (PVDF). However, recent reports have shown the potential for PVDF-based backsheets to crack and fail prematurely. Previous work has suggested that polymer
