    Highly conductive phase change composites based on paraffin-infiltrated graphite panels for photo/electrothermal conversion and storage 

    Nishad, Safna; Kasak, Peter; Krupa, Igor ( Elsevier , 2023 , Article)
    The extensive utilization of phase change materials (PCMs) for thermal energy harvesting, storage, and thermal management is often constrained by their inadequate thermal and electrical conductivity, form instability, and ...

    Reverse osmosis silica fouling control with reactive micromixing 

    Bai, Weiliang; Xu, Ruizhe; King, Daniel; Boehnke, Adam; Krupa, Igor; Kasak, Peter; Popelka, Anton; Saleh, Navid B.; Kumar, Manish... more authors ... less authors ( Elsevier , 2024 , Article)
    Silica fouling is a major challenge in groundwater reverse osmosis (RO) desalination. Dissolved silica, upon concentration during RO, forms a difficult-to-clean glassy foulant layer on membranes, limiting recoveries from ...
