The metal-supported reversible protonic ceramic cell (MS-rPCC) combines the dual advantages of metal support and proton conduction, enabling efficient low-temperature operation, high mechanical strength, and exceptional thermal cycling stability. However, a critical challenge in MS-rPCC fabrication lies in element diffusion from the metal support and the thermal expansion mismatch between the metallic and ceramic phases. To address this issue, a pure nickel metal support and a newly developed transition layer (80 wt.% NiO–20 wt.% BaZr0.1Ce0.7Y0.2O3-δ, BZCY) were employed to mitigate thermal expansion mismatch, thereby enhancing the performance and stability of the MS-rPCC. This work presents a novel approach to facilitate the commercialization and widespread application of MS-rPCC technology.

In this April 2025 issue of Translational Lung Cancer Research, a pioneering study, led by Professor Shuben Li from the First Affiliated Hospital of Guangzhou Medical University, revisits a classic but unresolved question in airway surgery: Should tracheobronchial anastomoses be routinely wrapped following resection and reconstruction?

The article, titled "Tracheobronchial resection and reconstruction: to wrap or not to wrap the anastomosis?"，presents a single-center experience to explore the relationship between wrapping the anastomosis after airway reconstruction and short-term surgical outcomes, and to investigate whether wrapping the anastomosis can reduce the incidence of postoperative adverse events.
