Dielectric Characterization of H2O and CO2 Uptake by Polyethylenimine Films

April 10, 2024
Author(s)
Jan Obrzut, Jennifer Clark, Avery Baumann, Jack F. Douglas
This study investigates the dielectric properties of branched polyethylenimine (PEI) films in relation to their interaction with moisture and CO2. The dielectric measurements were carried out using a non-contact resonant microwave cavity testing method

Assessing Composite Structure in Metal-Organic Framework-Polymer Mixed-Matrix Membranes

March 15, 2024
Author(s)
Avery Baumann, Peter Beaucage, Richard Vallery, David Gidley, Ryan Nieuwendaal, Chad R. Snyder, Jan Ilavsky, Fu Chen, Christopher Stafford, Christopher Soles
Metal-organic frameworks (MOFs) are renowned for their tunable structure, porosity, and internal chemistry with demonstrated applications in molecular separations, storage, and conversion. While they are widely usable, the powdery characteristics of MOF

Phosphate-Functionalized MOF-808 for High Performance Li-S Batteries

May 8, 2023
Author(s)
Bingqian Liu, Avery Baumann, Megan Butala, V. Sara Thoi
Lithium–sulfur batteries are promising candidates for next-generation energy storage devices due to their outstanding theoretical energy density. However, they suffer from low sulfur utilization and poor cyclability, greatly limiting their practical

Reproducible Sorbent Materials Foundry for Carbon Capture at Scale

September 22, 2022
Author(s)
Austin McDannald, Howie Joress, Brian DeCost, Avery Baumann, A. Gilad Kusne, Kamal Choudhary, Taner N. Yildirim, Daniel Siderius, Winnie Wong-Ng, Andrew J. Allen, Christopher Stafford, Diana Ortiz-Montalvo
We envision an autonomous sorbent materials foundry (SMF) for rapidly evaluating materials for direct air capture of carbon dioxide ( CO2), specifically targeting novel metal organic framework materials. Our proposed SMF is hierarchical, simultaneously
