Kinetically Controlling Surface Atom Arrangements in Thermally Robust, Amorphous High‐Entropy Alloy Nanoparticles by Solvent Selection

Advanced Science, EarlyView.
This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...

Toward decarbonization of the titanium industry via hydrogen plasma smelting reduction

Advanced Science, EarlyView.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Where Can Aluminum Go When Batteries Die?

Advanced Science, EarlyView.
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.
