    🎉New Paper Published in ACS Materials Au

    Our paper, “Stoichiometry-Defined Phase Selection and Hydrophobic Molecular Sealing in Bioderived Deep Eutectic Solvents,” has been published in ACS Materials Au (Impact factor 9.1) In this work, we developed a moisture-resistant bioderived deep eutectic solvent (DES) by combining acetylcholine chloride and 3-phenylpropionic acid. The optimized eutectic composition exhibited significantly reduced moisture uptake, high ionic conductivity, a wide electrochemical window, and excellent biodegradabil …

    Invited Seminar at National Tsing Hua University (Mar 19)

    I visited National Tsing Hua University (Taiwan) and delivered an invited seminar hosted by the Institute of Nano Engineering and Micro Systems. In this talk, titled “Transient Ionics: Biodegradable Electronic Materials that Disappear After Use,” I introduced our recent work on the design and applications of biodegradable electronic materials that safely decompose after use. In particular, I discussed transient electronics based on bioderived ionic liquids, biodegradable metal electrodes, and se …

    My Paper Accepted by ACS Applied Materials & Interfaces!

    I’m excited to share that my latest research has been accepted for publication in ACS Applied Materials & Interfaces. In this study, we developed a biodegradable temperature sensor using sodium-doped choline lactate ionic gel. By enhancing intermolecular interactions, we significantly improved the sensor’s temperature coefficient of resistance (TCR), achieving high sensitivity and long-term degradability. This work contributes to the advancement of flexible, eco-friendly sensors for wearable …
