Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

Advanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Interfacial Reconstruction Enables Enhanced Thermoelectric Performance in Bismuth Telluride‐Based Alloys

Advanced Science, EarlyView.
Bismuth telluride‐based alloys are benchmark thermoelectric materials for near‐room‐temperature applications. Here, SnSe‐induced interfacial reconstruction simultaneously optimizes carrier and phonon transport in Bi0.4Sb1.6Te3, achieving a peak ZT of ∼1.38 at 363 K and a device efficiency of ∼6.47%, providing an effective strategy for high‐performance ...

Rapid Solidification Brings Ultralow Thermal Conductivity and Superior Thermoelectric Performance for Intrinsic GeTe Alloy

Advanced Science, EarlyView.
Rapid solidification with glass fluxing is first applied to the intrinsic GeTe alloy and achieves large undercooling within 2 h. This enables partial retention of the high‐temperature cubic phase at room temperature and forms a crystallographically oriented α+β dual‐phase structure and a hierarchical defect network.

Beyond Formate Trapping: A Mechanistic Framework for Homogeneous CO2‐to‐Methanol Conversion With First‐Row Transition Metals

Angewandte Chemie, EarlyView.
This review shows that converting CO2 into methanol with catalysts based on abundant first‐row metals requires more than overcoming formate formation. Success depends on balancing hydrogen activation, intermediate reactivity, product release, and catalyst stability.
