Mass Production of Waste PVC‐Mediated Bamboo‐Derived Hard Carbon for Ultra‐Long Life Sodium Storage

Carbon Energy, EarlyView.
By a scalable PVC‐mediated bifunctional strategy, pre‐carbonized micrometer bamboo powder is converted into a functionally partitioned hard carbon anode with distinct domains. Featuring abundant internal closed pores and surface sp2‐enriched graphitic regions, this anode delivers exceptional high‐rate long‐cycle stability, retaining 93% capacity after ...

Atmospheric Plasma Sprayed YSZ Coatings for Soilless Cultivation

Journal of Thermal Spray Technology
Abstract In this work, thermally sprayed coatings with sustainable spray additives are developed to allow the growth of drought-tolerant plants like moss, microclover and Chamomile. The specified spray additives are intended to imitate the powders obtained from recycled solid oxide fuel cells and dry alkaline batteries. These plants anchor to

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
