Novel Sulfide‐Chloride Solid‐State Electrolytes with Tunable Anion Ratio for Highly Stable Solid‐State Sodium‐Ion Batteries

Advanced Materials, EarlyView.
A new family of Na‐Zr‐S‐Cl sulfide‐chloride Na SSEs with tailored anion compositions is explored. A high ionic conductivity is realized for both Cl‐rich and Cl‐deficient structures, attributed to the unique chloride bridging structure and low Na‐ion migration barrier.

Epsilon-Unfolding Orthogonal Polyhedra [PDF]

, 2006
An unfolding of a polyhedron is produced by cutting the surface and flattening to a single, connected, planar piece without overlap (except possibly at boundary points). It is a long unsolved problem to determine whether every polyhedron may be unfolded.

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials

Advanced Materials, EarlyView.
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Organic–Inorganic Hybrid Indium Halide Perovskites with Near‐Unity Photoluminescence Quantum Yield

Advanced Materials Interfaces, EarlyView.
The intrinsic low photoluminescence quantum yield (PLQY) of organic–inorganic hybrid halide perovskites has limited their applications in optoelectronic devices. In this work, novel (PMA)₄InCl₇·0.5H₂O single crystals are developed and a PLQY of approximately 100% through optimized antimony ion (Sb3⁺) doping is achieved. The light‐emitting diodes (LEDs)
