    Advances in porous organic polymers for efficient water capture

    Byun, Yearin ; Je, Sang Hyun ; Talapaneni, Siddulu Naidu ; Coskun, Ali

    In: Chemistry – A European Journal, 2019, vol. 25, no. 44, p. 10262–10283

    Desiccant driven dehumidification for maintaining the proper humidity levels and atmospheric water capture with minimum energy penalty are important aspects in heat pumps, refrigeration, gas and liquid purifications, gas sensing, and clean water production for improved human health and comfort. Water adsorption by using nanoporous materials has emerged as a viable alternative to...

    Perfluoroaryl‐elemental sulfur SNAr chemistry in covalent triazine frameworks with high sulfur contents for lithium–sulfur batteries

    Je, Sang Hyun ; Kim, Hyeon Jin ; Kim, Jiheon ; Choi, Jang Wook ; Coskun, Ali

    In: Advanced Functional Materials, 2017, vol. 27, no. 47, p. -

    In order to address the challenges associated with lithium–sulfur batteries with high energy densities, various approaches, including advanced designs of sulfur composites, electrolyte engineering, and functional separators, are lately introduced. However, most approaches are effective for sulfur cathodes with limited sulfur contents, i.e., <80 wt%, imposing a significant barrier in...
