Effect of Atomic Layer Deposition of Ultra‐Thin Oxide on Reactivity and Durability of Perovskite Oxygen Electrodes

open access: yesAdvanced Materials, EarlyView.
This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

Cold Atmospheric Plasma‐Activated Decellularized Extracellular Matrix Gel as a Tumor‐Infiltrating Immunoactivation Platform for Post‐Surgical Cancer Immunotherapy

open access: yesAdvanced Materials, EarlyView.
An injectable cold atmospheric plasma‐activated decellularized tumor extracellular matrix hydrogel is introduced as a post‐surgical immunoactivation platform. The engineered gel attracts residual tumor cells and induces immunogenic cell death, reshaping the tumor microenvironment and eliciting systemic antitumor immunity. In combination with checkpoint
