Phonon‐Driven Tetrahedral Tilts Enable Ultralow Bulk Thermal Expansion and Interstitial Oxide‐Ion Migration in Phenacite Solid Electrolytes

Advanced Science, EarlyView.
This work demonstrates a design paradigm of phonon‐driven negative‐thermal‐expansion (NTE) flexible framework that exploits the intrinsic lattice flexibility of NTE frameworks to simultaneously suppress thermal expansion and activate oxide‐ion conduction, offering a promising strategy to mitigate TEC mismatch in solid‐state ionic devices.

A Rigid–Foldable Kirigami‐Inspired Metamorphic Mechanism With Programmable Motion Modes and Self‐Locking

Advanced Science, EarlyView.
Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

Metal Active‐Site Exposure via Ligand Engineering Boosts CO2‐to‐Ethylene Conversion on Cu18 Nanoclusters

Advanced Science, EarlyView.
Through quantitative ligand stripping of [Cu18H17(PR3)10]+ nanoclusters via intramolecular interaction modulation, selectivity for CO2 electroreduction to C2H4 is significantly enhanced. The weakly coordinating ligand triggers dual‐ligand stripping (FEC2H4 = 70.59%), whereas the strongly coordinating ligand results in single‐ligand retention (FEC2H4 ...

Dimple‐Encoded Reprogrammable Origami

Advanced Science, EarlyView.
Local snap‐through of bistable dimples turns flat elastic sheets into reprogrammable origami structures. Interaction‐guided dimple arrays act as angle‐programmable hinge bands, enabling one sheet to morph into distinct polygonal and three‐dimensional configurations while retaining stable shapes for deployable and protective functions.

Simple offset algorithm for generating workpiece solid model for milling simulation

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
In the milling simulation of a large stamping die for an automobile part, a workpiece solid model is necessary as an input data. The initial shape of the workpiece is generally equivalent to an offset shape of the stamping die CAD model.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically
