Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

open access: yesAdvanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Interfacial Acid Sites‐Mediated ZnO‐Based Electrocatalysts for Sustainable Dual‐Pathway H2O2 Production and Rechargeable Zn‐H2O2 Electrochemical Cell

open access: yesAdvanced Materials, EarlyView.
In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Magnetic‐Field Modulation of Charge Transport in Non‐Fullerene Semiconductors for Enhanced Hydrogen Evolution

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...
