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.
Isosbestic behavior is a term used in spectroscopy, or the study of light and electromagnetic spectra, and references the specific wavelength in which the complete absorption of a solution is constant throughout the reaction, leading to a stable rate of absorbance throughout the entirety of the reaction. This type of behavior is typically viewed as an indicator that a chemical reaction has happened and the starting materials (reactants) have changed into the end materials (product) without any intermediates in between. However, researchers have found that this isn’t necessarily the case by using magic size clusters (MSCs) and precursors to reveal a relatively transparent intermediate involved in the reaction.
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.
Black soils, revered as the world's agricultural powerhouses, are rapidly deteriorating under mounting environmental and human pressures.
