Monitoring Protein Complexation with Polyphosphazene Polyelectrolyte Using Automated Dynamic Light Scattering Titration and Asymmetric Flow Field Flow Fractionation and Protein Recognition Immunoassay

April 21, 2023
Author(s)
Michael Lueckheide, Alexander Marin, Harichandra Tagad, Nicholas Posey, Vivek Prabhu, Alexander Andrianov
Polyphosphazenes represent a class of intrinsically flexible polyelectrolytes with potent immunoadjuvant activity, which is enabled through non-covalent self-assembly with antigenic proteins by charge complexation. The formation of supramolecular complexes

Correlating the Diffusion of Water in Model Polyamides with Controlled Crosslink Densities to the Performance in Reverse Osmosis Membranes for Desalination

April 18, 2023
Author(s)
Velencia Witherspoon, Kanae Ito, Chad R. Snyder, Madhusudan (Madhu) Tyagi, Tyler Martin, Peter Beaucage, Ryan Nieuwendaal, Richard Vallery, David Gidley, Jeffrey Wilbur, Dean Welsh, Christopher Stafford, Christopher Soles
To elucidate robust design cues for improving the active polyamide (PA) filtration layers in reverse osmosis (RO) membrane for desalination, we systematically reduce the cross-link density of a PA network based on m-phenylene diamine by substituting a

Synergistic Fire Resistance of Nanobrick-wall Coated 3D Printed Photopolymer Lattices

March 16, 2023
Author(s)
Thomas Kolibaba, Callie Higgins, Zack Buck, Dash Weeks, Jason Killgore
Photopolymer additive manufacturing has become the subject of widespread interest in recent years due to its capacity to enable fabrication of difficult geometries that are impossible to build with traditional modes of manufacturing. The flammability of

Effect of Aging on Unidirectional Composite Laminate Polyethylene for Body Armor

March 8, 2023
Author(s)
Amy Engelbrecht-Wiggans, Ajay Krishnamurthy, Amanda L. Forster
Ballistic-resistant body armor has increasingly been using flexible unidirectional (UD) composite laminates that comprise multiple layers in the armor construction. Each UD layer contains high-performance fibers held in place using very low modulus binder

Solvent Transport Model for Polyamide Nanofilm Membranes Based on Accurate Hansen Solubility Parameters

February 21, 2023
Author(s)
Min Gyu Shin, Wansuk Choi, June Huh, William Mulhearn, Jung Sun Hwang, Christopher Stafford, Jeong F Kim, Jung Hyun Lee
Polyamide (PA) nanofilm membranes for solvent filtration are widely used in various industries. However, reliable models that can describe solvent transport in PA membranes have yet to be developed owing to measurement challenges associated with the highly

Community Resource for Innovation in Polymer Technology (CRIPT): A Scalable Polymer Material Data Structure

February 20, 2023
Author(s)
Dylan Walsh, Weizhong Zou, Ludwig Schneider, Reid Mello, Michael Deagen, Joshua Mysona, Tzyy-Shyang Lin, Juan de Pablo, Klavs Jensen, Debra Audus, Bradley Olsen
Polymeric materials are integral components of nearly every aspect of modern life. However, developing cheminformatic solutions for polymers has been difficult since they are large stochastic molecules with hierarchical structures spanning multiple length

Quantitative relationships between film morphology, charge carrier dynamics, and photovoltaic performance in bulk-heterojunction binary vs. ternary acceptor blends

February 7, 2023
Author(s)
Weigang Zhu, Guoping Li, Subhrangsu Mukherjee, Natalia Powers-Riggs, Leighton Jones, Eliot Gann, R Joseph Kline, Andrew Herzing, Jenna Logsdon, Lucas Flagg, Charlotte Stern, Ryan Young, Kevin Kohlstedt, George Schatz, Dean DeLongchamp, Michael Wasielewski, Ferdinand Melkonyan, Antonio Facchetti, Tobin Marks
Addressing pertinent and perplexing questions regarding why nonfullerene acceptors (NFAs) promote higher power conversion efficiencies (PCEs) than traditional fullerenes and how photoactive bulk heterojunction (BHJ) film morphology, charge photogeneration

Sustainable Additive Manufacturing of Polyelectrolyte Photopolymer Complexes

January 29, 2023
Author(s)
Thomas Kolibaba, Jason Killgore, Callie Higgins
Polyelectrolyte complexes (PECs), assemblies of oppositely charged polymers with powerful properties and wide-ranging applications, are currently not melt-processable via any conventional means and have been limited commercially to applications only as
