Tailoring the Reversible Phase Transition of Perovskite Nanofiber Electrodes for High-Performance and Durable Reversible Solid Oxide Cells

Nano-Micro Letters (2025)

Chaofan Yin Jiaming Yang Jiangyuan Feng Yueyue Sun Zhengrong Liu

Abstract Reversible solid oxide cells (RSOCs) are capable of converting various energy resources, between electricity and chemical fuels, with high efficiency and flexibility, making them suitable for grid balancing and renewable energy consumption. However, the practical application of RSOCs is still limited by the insufficient activity and stability of the electrodes in different operating modes. Herein, a highly efficient symmetrical electrode composed of La 0.3 Sr 0.6 Ti 0.1 Co 0.2 Fe 0.7 O 3− δ (LSTCF) nanofibers and in situ exsolved Co 3 Fe 7 nanoparticles is developed for boosting the performance of RSOCs. The reversible phase transition, high activity and stability of the electrode have been confirmed by a combination of experimental (e.g., transmission electron microscopy and X-ray absorption fine structure) and computational studies. Electrolyte-supported RSOCs with the symmetrical electrode demonstrate excellent catalytic activity and stability, achieving a high peak power density of 0.98 W cm −2 in the fuel cell mode using H 2 as the fuel (or 0.53 W cm −2 using CH 4 as the fuel) and a high current density of 1.09 A cm −2 at 1.4 V in the CO 2 electrolysis mode (or 1.03 A cm −2 at 1.3 V for H 2 O electrolysis) at 800 °C while maintaining excellent durability for over 100 h.

Ascorbic Acid‐derived New Polymer Spheres via Ternary Copolymerization for Highly Effective Activation of B Cells

Advanced Functional Materials (2024)

Gengxu Han Fangshen Li Bin Yu Yumeng Liu Jiaming Yang

Abstract Lymphocytes are crucial to defend against harmful pathogens and sustain adaptive immunity. Developing immunomodulating materials to activate lymphocytes is imperative to induce effective and enduring immune responses. Here, a new polymer serving as a highly efficient activator of B cells is reported and corresponding polymer spheres are synthesized through a droplet‐assisted ternary copolymerization process of ascorbic acid, ethylenediamine, and glyoxal. In‐depth studies are conducted on the polymerization mechanisms and polymer spheres ranging from 250 to 1200 nm with various surface functional groups are synthesized. These prepared polymer materials exhibit remarkable immunomodulatory functions correlated to the polymer spheres' size and surface functional groups, and effective activations on B cells are observed in vivo and in vitro. Through cell phagocytosis experiments and RNA sequencing analysis, it is proposed that the selective phagocytosis of B cells and the presence of CD21 on the B cell membrane contribute to the activation of B cells. This work has extended the realm of immunological research from a unique perspective of chemical synthesis, further substantiating the fundamental research and application potential of designing immunomodulating polymers.

Healable Ionic Conductors with Extremely Low‐Hysteresis and High Mechanical Strength Enabled by Hydrophobic Domain‐Locked Reversible Interactions

Advanced Materials (2023)

Tianqi Li Xiang Li Jiaming Yang Haoxiang Sun Junqi Sun

Extremely low hysteresis, high mechanical strength, superior toughness, and excellent healability are essential for stretchable ionic conductors to enhance their reliability and meet for cutting-edge applications. However, the fabrication of stretchable ionic conductors with such mutually exclusive properties remains challenging. Herein, extremely low-hysteresis and healable ionic conductors with a tensile strength of ≈8.9 MPa and toughness of ≈23.2 MJ m-3 are fabricated through the complexation of 4-carboxybenzaldehyde (CBA) grafted poly(vinyl alcohol) (PVA) (denoted as PVA-CBA) and poly (allylamine hydrochloride) (PAH) followed by acidification and ion-loading steps. The acidification step generates the PVA-CBA/PAH ionic conductors with in situ formed dynamic hydrophobic domains that lock and stabilize noncovalent interactions. This significantly minimizes the energy dissipation of the ionic conductors during cyclic mechanical loading (≤200% strain), resulting in ionic conductors with extremely low hysteresis (≈5%). The fractured ionic conductors can be healed at 60 °C to restore their original properties. Because of the extremely low hysteresis, the PVA-CBA/PAH ionic conductors show a highly stable and reproducible electrical response over 5000 uninterrupted loading-unloading cycles at a strain of 200%. The ionic conductor based sensors exhibit a high sensitivity to a wide range of strains (1-500%).
