研究室紹介
Professor Hojin Ryu's research lab specializes in advanced functional materials for energy and environmental applications, with a focus on high-entropy alloys for fusion energy materials and carbon-based nanomaterials for sustainable technologies. The lab develops novel conductive nanocomposites using carbon nanotubes and graphene to enhance electrical performance in stretchable electronics and energy storage devices. A key research direction involves optimizing carbon nanotube dispersion and integration in electrodes for capacitive deionization, aiming to improve desalination efficiency for high-salinity water. The lab also investigates structural and mechanical properties of refractory metal-based alloys for extreme environment applications.

Selected Papers
15TaTiVCr high-entropy alloy with 32at.% of tungsten (W) and its derivative alloys with 42 to 90at.% of W with in-situ TiC were prepared via the mixing of elemental W, Ta, Ti, V and Cr powders followed by spark plasma sintering for the development of reduced-activation alloys for fusion plasma-facing materials. Characterization of the sintered samples revealed a BCC lattice and a multi-phase structure. The selected-area diffraction patterns confirmed the formation of TiC in the high-entropy alloy
Carbon nanotubes (CNTs) and graphene are known to be good conductive fillers due to their favorable electrical properties and high aspect ratios and have been investigated for application as stretchable composite conductors. A stretchable conducting nanocomposite should have a small fraction of conductive filler material to maintain stretchability. Here we demonstrate enhanced electrical networks of nanocomposites via the use of a CNT-graphene hybrid system using a small mass fraction of conduct
