Polyphenol‐Based Biomaterials Against Cancer Radio/Chemotherapy‐Induced Intestinal Toxicity

Advanced NanoBiomed Research, EarlyView.
Radiotherapy/chemotherapy often causes intestinal toxicity, impairing cancer patients’ quality of life and treatment efficacy. Polyphenols protect against this injury via multiple mechanisms, but face oral use limitations. This review outlines their protective mechanisms and delivery challenges, highlighting recent oral delivery advances and future ...

Mechanism‐Guided Precision Hydrolysis of Early Transition Metals to Access (Mixed‐Metal) Oxo Clusters

Angewandte Chemie, EarlyView.
Precision hydrolysis enables the rational, room‐temperature synthesis of Zr and Hf oxo clusters with improved atom economy, sustainable solvents, and gram‐scale yields. By adding exactly 1.33 equivalents of water, Zr6, Hf6, and elusive bimetallic clusters are accessed, alongside new group 5 oxo clusters, providing a versatile and economical platform ...

Trapping a Metastable Node in an Amorphous Metal–Organic Framework

Angewandte Chemie, EarlyView.
Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.
