Hydrogen‐Induced Amorphization of Superlattice Cerium Nickel Intermetallics Enabling Efficient Alkaline Oxygen Evolution Reaction

Advanced Science, EarlyView.
A gaseous hydrogen engineering strategy is employed to induce the amorphization of superlattice‐structured CeNi3 intermetallic, facilitating alkaline OER‐driven phase reconstruction and enhancing catalytic performance. ABSTRACT Transforming intermetallics with highly ordered structures into amorphous forms to unlock their superior oxygen evolution ...

Wastewater sewage sludge leaching and alkaline stabilization

, 2006
The constantly growing amount of unutilised wastewater sewage sludge (SS) remains an unsolved environmental problem in Lithuania. SS can serve efficiently as a renewable feedstock in agriculture for the production of composts, for recultivation of exhausted lands and for woodland soil improvement in forestry.

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Degradation Mechanism of Phosphate‐Based Li‐NASICON Conductors in Alkaline Environment

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The presence of water in the cathode of a Li‐air battery shifts reactions to produce LiOH, creating a corrosive, alkaline environment. This study investigates the alkaline stability of the common Li‐NASICON solid‐state conductor chemistries through a systematic experimental study combined with computational modeling to understand the degradation ...

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.

Compositional Tuning and Surface Restructuring Synergistically Enhance Perovskite Ferrite Catalysts for Hydrogen Evolution in a Membrane‐Less Electrolyzer

Advanced Energy Materials, EarlyView.
In this work, a self‐restructuring Fe‐based perovskite catalyst is developed, leveraging in situ amorphization to achieve a “self‐improving” behavior for hydrogen evolution. When integrated into a custom‐built membrane‐less electrolyzer, the system demonstrates a record‐breaking 1000 h stability, providing a robust and practical pathway for the ...
