Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

Advanced Science, EarlyView.
An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

The Phase Space Density Evolution of Radiation Belt Electrons under the Action of Solar Wind Dynamic Pressure

Magnetochemistry, 2023
Earth’s radiation belt and ring current are donut-shaped regions of energetic and relativistic particles, trapped by the geomagnetic field. The strengthened solar wind dynamic pressure (Pdyn) can alter the structure of the geomagnetic field, which can ...

Foam Injection Molded Stereocomplex PLA: Processing, Thermal Behavior and Foam Structure

Journal of Applied Polymer Science, EarlyView.
The processing of stereocomplex poly(lactic acid) (sc‐PLA) via continuous compounding followed by thermoplastic foam injection molding is investigated. A controlled two‐stage cooling strategy effectively promotes sc‐dominated crystallization of the granulates.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Importance of electron distribution profiles to chorus wave driven evolution of Jovian radiation belt electrons

Earth and Planetary Physics, 2018
Wave-particle interactions triggered by whistler-mode chorus waves are an important contributor to the Jovian radiation belt electron dynamics. While the sensitivity of chorus-driven electron scattering to the ambient magnetospheric and wave parameters ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
