Sustainable Synthesis of Edge‐Dominant Pyridinic Nitrogen‐Doped Carbon from Tannic Acid for High‐Performance Vanadium Redox Flow Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphitic carbon doped with an edge‐predominant pyridinic structure is synthesized using a sustainable, rapid microwave process. The material enhances vanadium redox reactions, improving energy efficiency and durability in VRFB electrodes, with a 94.12% discharge capacity retention over 1000 cycles.

Development of Coupled Electrochemical Systems for Metal Resource Recovery From Aqueous Metal‐Organic Complexes

open access: yesRare Metals, EarlyView.
ABSTRACT The past decade has witnessed a burgeoning demand of metals for global industrial development and infrastructure. Meanwhile, the depletion of mineral resources and the environmental damage caused by wastewater discharges pose significant threats to both economic and ecological sustainability. Fortunately, metal‐containing wastewaters also hold

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

open access: yessteel research international, EarlyView.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.
