Expandable Nanocomposite Shape‐Memory Hemostat for the Treatment of Noncompressible Hemorrhage

Advanced Science, EarlyView.
A nanocomposite‐coated shape memory foam rapidly expands, accelerates clotting, and reduces blood loss in vivo. Its fast volumetric expansion and strong procoagulant activity make it a promising hemostat for treating deep, noncompressible hemorrhage.

Lewis Pair‐Engineered CuMnOx as Cold‐Adapted Multinanozyme for Cooperative Hydrolytic and Oxidative Degradation of Raw Corn Stalk

Advanced Science, EarlyView.
A Lewis pair site design strategy was established to construct Cu‐doped Mn‐based amorphous nanozymes, where Mn and oxygen vacancies generate cooperative acid‐base pairs. The resulting multinanozyme integrates glycosidase‐, oxidase‐, and cold‐adapted enzyme‐mimicking activities, enabling cooperative depolymerization of cellulose and hemicellulose ...

Quantitative Stain Mapping in X‐Ray Virtual Histology

Advanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach
