NaHSO3 as a Key Component in Developing Enhanced Performance Electrolytes for All‐Iron Redox Flow Batteries

Battery Energy, EarlyView.
A novel electrolyte for all‐iron redox flow batteries has been proposed with NaHSO3 as a key component. Even in small amounts, it significantly increases the plating/stripping processes occurring in the negative half‐cell (limiting step). Thanks to the formation of a FeHSO3+ intermediate, which acts as a very effective catalyst for the metallic iron ...

Nickel‐Doped h‐MoO3 Cathodes: A High‐Performance Material for Aluminum‐Ion Batteries

Battery Energy, EarlyView.
Nickel‐doped hexagonal molybdenum trioxide (h‐MoO₃) shows a promising improvement in the capacity and stability of aluminum‐ion batteries. This work utilizes a simple precipitation method to incorporate nickel into h‐MoO₃, combined with a urea‐based electrolyte, achieving higher discharge capacities and extended cycling stability.

Green Propolis Extract‐Mediated Synthesis of Biogenic Silver Nanoparticles: In Vitro Antileishmanial and Antibacterial Activities, Cytotoxicity and Ex Vivo Irritation Testing

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study describes the green synthesis, characterization, and biological evaluation of silver nanoparticles (AgNPs) obtained from green propolis (AgNPs‐PRO). Before nanoparticles synthesis, a hydroethanolic green propolis extract (GPE) was obtained through ultrasound‐assisted extraction and characterized by high‐performance liquid ...
