Mediation of Oxidation and Spin States of Fe/P‐CoO2 Core–Shell Structures Catalysts for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...

Material Composition Gradient Controls the Autonomous Opening of Banksia Seed Pods in Fire‐Prone Habitats

Advanced Functional Materials, EarlyView.
The seed pod valves of Australian Banksia attenuata plants are not simply bi‐layers which bend when dry. These experiments and models reveal complex mechanics, which allow seed release only after several steps of seed pod opening. Stiffness gradients prevent delamination of the valves during loading, and a shape‐memory function protects the seeds ...

Electroplating of Wear‐ and Corrosion‐Resistant CrCoNi Medium‐Entropy Alloys beyond Hard Chromium Coatings

Advanced Functional Materials, EarlyView.
The electroplating of a CrCoNi medium‐entropy alloy is achieved using a mixture of an ionic liquid and an aqueous solution containing metal salts. The CrCoNi medium‐entropy alloy thin film exhibits high wear and corrosion resistance superior to conventional hard chromium coatings. Abstract High‐entropy alloys (HEAs) and medium‐entropy alloys (MEAs) are

Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6

Advanced Functional Materials, EarlyView.
This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

Covalent On‐Cell Conjugation of Biomaterials Through Oxidative Phenolic Coupling Regulates Stem Cell Fate via Intracellular Biophysical Programming

Advanced Functional Materials, EarlyView.
On‐cell covalent crosslinking of hydrogel matrix to the membrane of a single cell using droplet microfluidics enables mechanotransduction and influences stem cell fate. This newly established approach influences stem cell fate, independent of YAP/TAZ mechanotransduction and non‐covalent reversible binding ligands yet by various intracellular ...

Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates

Advanced Functional Materials, EarlyView.
The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Picosecond lifetimes of hydrogen bonds in the halide perovskite CH$_3$NH$_3$PbBr$_3$ [PDF]

arXiv
The structures and properties of organic-inorganic perovskites are influenced by the hydrogen bonding between the organic cations and the inorganic octahedral networks. This study explores the dynamics of hydrogen bonds in CH$_3$NH$_3$PbBr$_3$ across a temperature range from 70 K to 350 K, using molecular dynamics simulations with machine-learning ...

2D Covalent Moiré Superlattice from Fluorinating Twisted Bilayer Graphene

Advanced Functional Materials, EarlyView.
A novel class of moiré materials, termed covalent moiré superlattice is proposed, which can be synthesized by functionalizing moiré van der Waals materials. By fluorinating twisted bilayer graphene, the weak van der Waals interactions between twisted graphene layers are transformed into strong covalent bonds, making the moiré superlattice effects ...
