In-situ thermo-mechano-chemical transformation and consolidation of Sm-Co powders via a single-step route for bulk magnet fabrication

Nature Communications
The demand for high-performance permanent magnets continues to grow across a wide range of advanced technologies. However, conventional powder metallurgy routes for rare-earth magnets such as Sm–Co are limited by the intrinsic brittleness of the powders,

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

Archaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Chemical Prelithiation of Silicon Powder and its Role as Anode Material for All‐Solid‐State Batteries

Batteries &Supercaps, EarlyView.
This article explores a carrier‐type approach for the chemical prelithiation of silicon (Si) powder and investigates the integration of prelithiated silicon (LixSi) as electrolyte‐free anode in sulfide‐based all‐solid‐state batteries. In comparison to a Si anode, the LixSi anodes showed improved cycle stability at 2 C, but revealed kinetic limitations ...

Unlocking the Potential of Electrolyte Recovery from Battery Waste: A Promising Path to Sustainable and Safe Li‐Ion Batteries

Batteries &Supercaps, EarlyView.
Due to several challenges, electrolyte recovery from spent battery waste has been less explored compared to electrode materials. This study presents various strategies for recovering electrolytes from spent battery waste. Electrolyte recovery can prevent hazardous chemicals from being released into the environment.
