Ultrafast Mechanochemical Synthesis of Plasmonic Transition Metal Nitride Nanoparticles

open access: yesSmall, EarlyView.
Mechanochemistry enables ultrafast synthesis of plasmonic transition metal nitride nanoparticles in minutes rather than hours without external heat supply. The resulting mono‐ and mixed‐metal nitrides display tunable plasmonic absorption, demonstrating a potentially scalable route to refractory plasmonic materials.

Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

open access: yesSmall, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

open access: yessteel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...
