Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...

Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Supervariate Gel Transforms into Various Biominerals in Salt Solutions

open access: yesAdvanced Functional Materials, EarlyView.
It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

Au@h‐BN Core–Shell Nanostructure as Advanced Shell‐Isolated Nanoparticles for In Situ Electrochemical Raman Spectroscopy in Alkaline Environments

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.

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 ...

Low‐Temperature Exsolution of Cobalt From Perovskite Nanoparticles via Bead Milling for Enhanced Electrocatalytic Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
High‐temperature requirements and complex synthesis limit the practical use of perovskite‐based metal exsolution catalysts. This study addresses these limitations by employing bead milling, enabling efficient metal exsolution at a significantly lower temperature (300 °C) from La0.6Sr0.4CoO3‐δ nanoparticles. Consequently, the catalytic mass activity for
