Adaptive Metafilm With Scalable Phase‐Tunable Emissivity for Energy‐Efficient Thermal Management

open access: yesSmall, EarlyView.
ABSTRACT Efficient thermal management of enclosed systems through controlled manipulation of radiative cooling power represents a key functionality of adaptive composite metamaterials. Such materials enable precise regulation of heat emission under varying environmental conditions while maintaining scalability and durability.

Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

open access: yesSmall, EarlyView.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

Enhanced Synthesis and Electrochemical Performance of Cobalt Hexacyanoferrate via Protonation‐Regulated Coprecipitation

open access: yesSmall, EarlyView.
A novel synthesis strategy is proposed which leverages the distinct acid–base equilibria of two hexacyanoferrate species for the rapid, chelator‐free production of low defect cobalt hexacyanoferrate (CoHCF). Despite a processing time of ∼15 min, the resulting CoHCF prepared via the protonation‐regulated coprecipitation exhibits excellent energy density

Scandium Doping and Coating for Improving O3‐NaNi1/2Mn1/2O2 Electrode in Sodium Battery

open access: yesSmall, EarlyView.
Scandium incorporation into O3‐Na[Ni1/2Mn1/2]O2 enhances cycling stability through distinct bulk and interfacial mechanisms. Bulk Sc3+ doping stabilizes the lattice and suppresses the O′3 phase, while Sc2O3 coating mitigates interfacial degradation. Together, these strategies markedly improve long‐term performance, offering a pathway to design durable ...
