Measuring the Dynamic Nanometric Contact Radius of a Single Microdroplet on an Electrified Microinterface

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Electrochemical measurements as single aqueous microdroplets collide with electrode interfaces reveal nanoscale wetting dynamics. By tuning electrostatic repulsion, we control contact formation and probe surface interactions well beyond the optical diffraction limit.

Slowing Down Zinc Electrodeposition Kinetics Can Maximize and Compromise Anode Stability: How Slow Is Too Slow?

open access: yesAngewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Zinc anode performance is maximized within an optimal deposition‐kinetic window. Additives that tune the deposition exchange current density (i0,Dep) suppress HER at intermediate values, but overly fast kinetics promote dendrites and overly slow kinetics accelerate corrosion/HER.
