Electric‐Fish‐Inspired Thin Hydrogel Electrocytes Achieve High Power Density and Environmental Robustness

Advanced Science, EarlyView.
This study presents thin, environmentally stable hydrogel power sources inspired by electric fish. Made using layer‐by‐layer spin‐coating with glycerol‐enhanced solutions, they offer precise layer control, long‐term hydration, and anti‐freezing stability.

Active Thermal Metasurfaces Enable Superscattering of Thermal Signatures Across Arbitrary Shapes and Thermal Conductivities

Advanced Science, EarlyView.
This study proposes a thermal superscatterer capable of manipulating thermal scattering signatures far exceeding the actual scale of objects. Utilizing transformation thermotics and active thermal metasurfaces, the device reproduces the thermal scattering signature of the enlarged thermal scatterer.

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation

Advanced Science, EarlyView.
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

Flexible Thermoelectrics for Wearable Electronics: Trends and Benchmarks in Solid‐State and Ionic Materials, Textile Architectures, Interface Engineering, and Device Performance

Advanced Electronic Materials, EarlyView.
Thermoelectric generators (TEGs) convert waste heat into electricity for self‐powered and wearable electronics. This review highlights advances in flexible, hybrid, and ionic thermoelectric materials, emphasizing ionic thermopower control, textile integration, and hybrid TEG–supercapacitor systems for combined harvesting, sensing, and storage.
