A Hexadecacationic Metal–Organic Cage for Anchoring Sulfonates: High‐Order Binding of Di‐ and Trisulfonates and High‐Performance Removal of Perfluorosulfonates from Water

open access: yesAdvanced Science, EarlyView.
Developing synthetic hosts that can bind sulfonate anions or sequester perfluorosulfonates is crucial in biological and environmental sciences. Here, a Zr‐based metal–organic cage (1) integrating electron‐deficient tripyridinium panels is designed and synthesized.

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

open access: yesAdvanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

A Multi‐Stimuli‐Responsive Pd2L4 Metallacage for Amino Acid Sensing

open access: yesAggregate, EarlyView.
A multi‐stimuli‐responsive metallacage was constructed via a bottom‐up design strategy, and its stimuli‐responsive behaviors were investigated in response to basic/acidic reagents, naphthalene disulfonate, and thiol‐containing amino acids, accompanied by remarkable structural transformations and fluorescence variations.
