Nanoporous polymer networks can help advance the next generation of catalytic technologies. In a paper authored by Dr. Keira Culley, in which I assisted with X-ray scattering experiments, we see the realm of possibilities offered by highly ordered lyotropic networks. Cubic networks made of lyotropic materials, as evidenced by previous work, can exhibit size-discrimination. If…

The next generation of batteries and energy generation devices require both precise, size-controlled engineering and renewable materials sources. My good colleague Dr. Ruiqi Dong and I aimed to accomplish both of these goals in a study published in ACS Materials Letters. The article, linked here, showed that we can rapidly conduct potassium through a polymer…

The Vagelos Institute for Energy Science and Technology at the University of Pennsylvania gave me the opportunity to meet some of the most talented scientists I have had the pleasure of working with. Myself, Dr. Ranadeb Ball, and Lizhu Zhang explored the fundamentals of ion transport in nanopores, using the lyotropic mesophase system that had…

The following is the abstract of work published in Advanced Materials Interfaces, which I performed as a co-first author with Dr. Patrick Li. This was my first scientific paper, and I had a lot of fun during it. We made films that were resilient to acid, and were the first example to our knowledge of…
