Where Can Aluminum Go When Batteries Die?

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
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.

Type II Hot Corrosion of Two Mo‐Si‐Ti Alloys and Mo‐Si‐B With a Salt Deposit of Mixed Na2SO4 and NiSO4

open access: yesMaterials and Corrosion, Volume 77, Issue 2, Page 177-187, February 2026.
Schematic drawings of the hot corrosion mechanisms of (a) Mo‐9Si‐8B (at.%), (b) Mo‐21Si‐34Ti (at.%) and (c) Mo‐20Si‐52.8Ti (at.%) with a NiSO4/Na2SO4 deposit at 700°C in a SO2‐containing atmosphere. ABSTRACT To enhance turbine efficiencies by increasing gas inlet temperatures, new materials must be developed which can withstand harsh corrosive ...

Vibrational Analysis of Steelmaking Ladles: Findings from Industrial and Laboratory Studies for Model Development and Stirring Optimization

open access: yessteel research international, Volume 97, Issue 2, Page 1098-1108, February 2026.
Vibration signals are generated by argon gas injection in molten metal and are measured in both industrial and laboratory ladles. Distinct frequency bands are identified, corresponding to bubble formation and rupture. The results demonstrate that vibration analysis can provide valuable insights into bubble dynamics and support optimization of gas ...

Dispersed Nickel on Gallium Liquid Metal for Nitrate Reduction to Ammonia

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
Developing sustainable catalytic systems for green ammonia synthesis is essential to achieving net‐zero emission targets. This study introduces a liquid Ni–Ga alloy catalyst with dispersed Ni sites for efficient nitrate‐to‐ammonia conversion with exceptional Faradaic efficiency and considerable production rate.

Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Floating zone growth of high‐purity MgO substrate single crystals

open access: yesActa Crystallographica Section B, Volume 82, Issue 1, Page 2-13, February 2026.
High‐purity MgO substrate crystals grown by the optical floating zone technique are demonstrated, which can serve as a foundation for the development of novel device concepts based on epitaxially grown thin films.MgO single crystals with diameters between 3.5 and 5 mm and lengths up to 40 mm were grown by the optical floating zone technique (OFZ ...

Semidiaphanam Tremuli Narcissuli Ideam Lacteam1: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

open access: yesArchaeometry, Volume 68, Issue 1, Page 120-131, February 2026.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
