Collective Dynamics of Urease‐Based Nanomotors in a Chemical Gradient
Small, EarlyView.This study investigates the collective migration of urease‐based nanomotors in a urea gradient. It identifies three governing mechanisms: density‐driven convection, chemotactic response to urea, and a coupling effect arising from ion–gel interactions.

Kinetic Insights into the Supramolecular Polymerization of Perylenediimide‐Appended Dipeptides
Small, EarlyView.The synthesis of dipeptide‐functionalized PDIs 1 and 2 has been accomplished, and their self‐assembly properties investigated. The dipeptide linkers facilitate the formation of diverse metastable monomeric species. However, these species have minimal influence on the supramolecular polymerization of PDIs 1 and 2.

Small Science, EarlyView.A modular hybrid membrane is constructed via a layer‐by‐layer strategy, integrating glucose oxidase/horseradish peroxidase or glucose oxidase/nanozyme‐loaded microreactors within alternating polyelectrolyte layers on a calcium carbonate core. This hierarchical design enables precise spatial confinement of catalytic units, facilitating efficient cascade
