Platinum‐free hydrogen photocatalysis is achieved using dibenzothiophene‐S,S‐sulfoxide‐based conjugated polymers, self‐assembled into nanoparticles via nanoprecipitation. Through side chain engineering and donor–acceptor design, these materials reach a hydrogen evolution rate of 209 mmol g⁻¹ h⁻¹. The structure–function insights presented here establish

High Ionic Seebeck Effect in Natural Leaves
This work reveals a role of natural leaves as thermoelectric biomaterials, capable of converting heat into electricity through the ionic Seebeck effect. The leaves exhibit significant and reproducible thermopower under both moderate temperature gradients and photothermal conditions.

This work demonstrates a strategy to spatially control supramolecular chirality by leveraging spontaneous twist self‐assembly in liquid crystal materials. It is generated by periodic zigzag line defects that define alternating enantiomeric domains, stabilized by a polymer network. This approach enables precise defect engineering, tunable chirality, and

High‐Performance Air‐Stable Polymer Monolayer Transistors for Monolithic 3D CMOS logics
A fibrillar polymer monolayer with a self‐confinement effect is demonstrated, in which aligned chains parallel the nanofiber axis. Employing a top‐gate CYTOP dielectric, this monolayer transistor achieves high mobility (7.12 cm2 V−1 s−1) and exceptional stability over 1260 days in air.

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Fe(III)‐Mediated Formation of Cu Nanoinclusions and Local Heterojunctions in CuWO4 Photoanodes
Fe(III) mediates the self‐assembly of CuWO4 nanostructures into core–shell architectures with Cu inclusions and WO3‐rich shells, enabling local p–n junction formation. This nanostructural transformation enhances charge separation and enables dual activity: oxygen evolution under photoelectrochemical operation and reactive oxygen species (ROS ...

Freestanding TiN–Au vertically aligned nanocomposite (VAN) thin films are fabricated by dissolving a Sr3Al2O6 sacrificial layer and releasing from the substrates. Freestanding VAN films combine flexibility with strong plasmonic resonance properties, providing a versatile platform for future applications in flexible photonics, plasmonics, and integrated

How to Manufacture Photonic Metamaterials
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
