Defect‐Engineered Multi‐Intermetallic Heterostructures as Multisite Electrocatalysts for Efficient Water Splitting

Advanced Science, EarlyView.
A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability

Advanced Atomic Layer Modulation Based Highly Homogeneous PtRu Precious Metals Alloy Thin Films

Advanced Science, EarlyView.
A unique idea of atomic layer modulation (ALM) that sequentially pulses DDAP and Ru(TMM)(CO)3, two precursors with one counter reactant O2 to produce ALM‐PtRu homogeneous PtRu bimetallic alloys at the nanoscale. It smartly adjusted precursor pulse time and temperature, ensuring stoichiometric and compositionally atomistic controlled highly ...

Ultrasound‐Responsive Piezoelectric Membrane Promotes Osteoporotic Bone Regeneration via the “Two‐Way Regulation” Bone Homeostasis Strategy

Advanced Science, EarlyView.
Patients with osteoporosis face a higher risk of bone injury, mainly due to weakened osteogenic differentiation and bone formation, along with increased osteoclast differentiation and bone resorption activity, leading to bone homeostasis imbalance.

Magnesium‐Mediated Electrochemical Synthesis of Ammonia

Advanced Science, EarlyView.
This study demonstrates a lithium‐free, magnesium‐mediated electrochemical process for converting nitrogen (N₂) to ammonia (NH₃) under mild conditions. Using abundant materials, the system achieves ≈27% Faradaic efficiency at lower voltages than Li‐ and Ca‐mediated systems.
