Impact of Extrusion and Direct Calendering on Dry‐Coated Cathodes for Sulfidic All‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
This work demonstrates a parameter optimization for a scalable dry coating process of sulfidic ASSB cathodes (82 wt% CAM, 0.5 wt% PTFE binder) in dry room atmosphere. High‐shear extruder mixing and calendering are used to form a cathode film based on PTFE fibrillation.

Thermoelectric Performance and Morphological Stability of Thin Titania: Carbon Black Hybrid Films Against Humidity and Light Irradiation

Advanced Energy and Sustainability Research, EarlyView.
Nanostructured titania:carbon black hybrid films, fabricated via water‐based slot‐die coating, show stable thermoelectric performance under light irradiation but degrade under high humidity. Operando grazing incidence small‐angle X‐ray scattering reveals humidity‐induced morphological changes correlating with reduced Seebeck coefficients.

Volatility analysis and forecasting of vegetable prices using an ARMA‐GARCH model: An application of the CF filter and seasonal adjustment method to Korean green onions

Agribusiness, EarlyView.
Abstract The vegetable market experiences significant price fluctuations due to the complex interplay of trend, cyclical, seasonal, and irregular factors. This study takes Korean green onions as an example and employs the Christiano–Fitzgerald filter and the CensusX‐13 seasonal adjustment methods to decompose its price into four components: trend ...
