Polysulfide-Blocking Microporous Polymer Membrane Tailored for Hybrid Li-Sulfur Flow Batteries
Changyi Li,Changyi Li,Ashleigh L. Ward,Sean E. Doris,Sean E. Doris,Tod A. Pascal,David Prendergast,Brett A. Helms +7 more
TL;DR: It is shown here that size- and ion-selective transport can be achieved using membranes fabricated from polymers of intrinsic microporosity (PIMs), and significantly improved battery performance was demonstrated, even in the absence of LiNO3 anode-protecting additives.

Processable Cyclic Peptide Nanotubes with Tunable Interiors
Rami Hourani,Chen Zhang,Rob van der Weegen,Luis Ruiz,Changyi Li,Sinan Keten,Brett A. Helms,Ting Xu +7 more
TL;DR: The new design of such a cyclic peptide enables one to modulate the nanotube growth process to be compatible with the polymer processing window without compromising the formation of high aspect ratio nanotubes, thus opening a viable approach toward molecularly defined porous membranes.

Engineered Transport in Microporous Materials and Membranes for Clean Energy Technologies.
Changyi Li,Stephen M. Meckler,Zachary P. Smith,Jonathan E. Bachman,Lorenzo Maserati,Jeffrey R. Long,Jeffrey R. Long,Brett A. Helms +7 more
TL;DR: An overview of the microporous materials chemistry driving advanced membrane development, the clean-energy separations employing them, and the theoretical underpinnings tying membrane performance to membrane structure across multiple length scales is provided.
Mechanistic insight into the formation of cationic naked nanocrystals generated under equilibrium control.
TL;DR: It is found that cationic NC surfaces are transiently stabilized post-stripping by physisorbed anionic species that arise from the reaction of BF3 with native ligands, which allows polar dispersants to reach the NC surface before cation desorption can occur.
Sub-micron Polymer-Zeolitic Imidazolate Framework Layered Hybrids via Controlled Chemical Transformation of Naked ZnO Nanocrystal Films
Stephen M. Meckler,Stephen M. Meckler,Changyi Li,Changyi Li,Wendy L. Queen,Teresa E. Williams,Teresa E. Williams,Jeffrey R. Long,Jeffrey R. Long,Raffaella Buonsanti,Delia J. Milliron,Brett A. Helms +11 more
TL;DR: In this article, it was shown that the ZnO-to-ZIF chemical transformation can be performed in less than 30 min under microwave conditions using a solution of the imidazole ligand in N,N-dimethylformamide (DMF), water, or mixtures thereof.
