ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction

Advanced Science, EarlyView.
The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.

Effective Solvent‐Engineered All‐Inorganic CsPbI2Br Perovskite Solar Cells

Advanced Science, EarlyView.
All‐inorganic CsPbI2Br perovskite composition has gathered a lot of attention in recent years due to its thermal robustness, convenience for space applications as well as for the all‐perovskite triple junction applications as a top cell due to its wide‐bandgap (1.9 eV) nature.

Sublattice‐Resolved Magnetoelastic Coupling and Opposing Pressure Responses in the Frustrated Magnetocaloric GdMn2O5

Advanced Science, EarlyView.
In GdMn2O5, sublattice‐resolved EXAFS and diffraction analysis reveal pronounced spin‐phonon coupling and an unexpected opposing pressure response: the Mn‐driven Néel temperature slightly decreases while the Gd‐sublattice ordering temperature rises under pressures up to 0.86 GPa.

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.

Mechanisms of Temperature‐Dependent Hysteresis in Freestanding BaTiO3/MoS2 Heterostructures

Advanced Science, EarlyView.
Freestanding ferroelectric BaTiO3 membranes are combined with monolayer MoS2 into 2D field‐effect transistors. At room temperature they provide ultrahigh‐κ gating with steep subthreshold swing and minimal hysteresis. Upon cooling, strong ferroelectric switching produces two stable memory states with long retention times.

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

Advanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.

Improving High‐Temperature Operational Stability of Inverted Perovskite Solar Cells Through MXene Heat‐Dissipating Layers

Advanced Science, EarlyView.
MeO‐2PACz‐functionalized MXene nanosheets create a thermally conductive buried interface in inverted perovskite solar cells. The interface improves heat spreading, suppresses defects and ion migration, and strengthens charge extraction, extending T80 at 65°C from 141 to 687 h while maintaining competitive efficiency.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.
