Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

We experimentally demonstrate the use of a multi-plane light converter (MPLC) as a non-mode selective (de)multiplexer for converting Hermite-Gaussian (HG) modes into a Hadamard matrix of fundamental Gaussian spots and vice versa.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Analysis of Optical Bottle Generation by Coherent Beam Combining
The study evaluates the feasibility of generating a closed optical trap (“optical bottle”) using coherent beam combining. A semi-analytical model, based on paraxial wave optics and truncated Gaussian beam approximation, was employed. Proposed configurations include: (1) simple bifocal tilt, (2) bifocal tilt + polarization switching, (3) bifocal tilt +

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Chitin‐Derived Carbon‐Metal Functional Materials
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Enhanced Supermode Stability in Weakly Anti-Guided Dual-Cavity Photonic Crystal VCSEL Arrays
We report on 940 nm dual-cavity photonic crystal vertical-cavity surface-emitting laser (VCSEL) arrays fabricated at a commercial foundry. These arrays leverage an anti-guided design enabled by reduced electrical resistance between optically coupled ...

Combined UV–vis transmittance and wavelength‐dependent photo‐assisted DC I–V analyses reveal defect‐induced optical instability and a high density of deep donor‐like subgap traps in La‐doped SrSnO3. The resulting MOSFET achieves one of the highest on/off ratios reported for ABO3 perovskite devices, demonstrating the promise of stannate perovskites as ...
