Hydrogen‐Bubble Repellent Conjugated Polymeric Coating for Improving Electrochemical Hydrogen Evolution.

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogen‐bubble repellent conjugated polymeric coating improves an electrochemical hydrogen evolution reaction maintaining a lower overpotential, a highly electrochemically active surface area and smaller Tafel slope. While the hydrogen‐bubble repellence because of polyglycerol moiety ensures an early detachment of produced hydrogen gas bubbles, the ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

open access: yesAdvanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

Probing Early Particle‐Cell Membrane Interactions via Single‐Cell and Single‐Particle Interaction Analysis

open access: yesAdvanced Functional Materials, EarlyView.
The pre‐internalization phase of endocytosis remains poorly characterized at single‐cell levels. Single‐cell pre‐internalization mechanics are investigated using advanced robotic techniques. Cancer cells exhibit biphasic adhesion – rapid initial binding followed by reinforcement – while fibroblasts show gradual engagement.

Multifunctional Polyfluoride Ionogel‐Encapsulated Lithium Anodes for Durable and Safe Pouch Cells under Harsh Conditions

open access: yesAdvanced Functional Materials, EarlyView.
In this work, it is developed a multifunctional polyfluoride ionogel via in situ thermal polymerization to encapsulate lithium metal anodes, integrating flame‐retardant capability, hydrophobicity, dynamic self‐healing behavior, and high ionic conductivity.
