And at times, we had no idea where it was going except to say lets try it, and thats really the fun part about Cornell. To our knowledge, this is at least the first method where now we are able to actually crystallize periodically ordered polymer-inorganic composite materials with a feature size of 10-20 nanometers, and yet several hundreds of micrometers thick, for example, in the bulk form, under five seconds and less. All are welcome. Can we use CO2 to make it directly into the precursors of monomers to form new polymers and use them in the structure formations? More often than not, other people who are not in your group might not spend the effort. Congratulations all! Multiple sequential partial cation exchange reactions can produce libraries of exceptionally complex heterostructured nanoparticles, but the first partial exchange reaction is responsible for defining the intraparticle frameworks, The lack of freshwater has been threatening many people who are living in Africa, the Middle East, and Oceania, while the discovery of freshwater harvesting technology is considered a promising solution. Recent advances in structured surface materials, metalorganic frameworks, hygroscopic inorganic compounds (and derivative materials), and functional hydrogels have demonstrated their potential as, Achieving kinetic control to synthesize metastable compounds is a challenging task, especially in solid-state reactions where the diffusion is slow.

Thank you, TTC, HKUST! We had a great time. May 2022. It was an honor that the work we have done, including at Cornell, was recognized. How can we recycle existing oxides or existing solids, get them back into the precursor forms, and use them to build new structures and new materials? The new composites, comprising carbon nanotubes embedded in bottlebrush polymer networks, are several orders of magnitude softer than comparable materials that involve linear polymer networks. So while Wiesner and Thompson had been the primary drivers of my research, I got to interact with other faculties materials science, chemistry, physics, and chemical engineering like Professor Lara Estroff, where I started to learn how biomaterials interact with polymers, and Professor Frank DiSalvo, whom is always kind to share his insights in the phase transitions of nanostructured materials.
