Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

A Host‐Guest, Zeolite/Organocation Material With Isotropic Zero Thermal Expansion
The use of selected organic structure directing agents for the hydrothermal synthesis of targeted zeolites exhibiting negative thermal expansion provides a straightforward strategy to obtain a new class of host‐guest, nanostructured, crystalline zero thermal expansion materials made of light and abundant elements.

This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries
Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.
