Where Can Aluminum Go When Batteries Die?
Advanced 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.

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...

Mullite production by valorization of a hydrodesulphurization catalyst waste
Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Due to its high alumina and silica content, Ni–Mo catalyst waste is a suitable, amorphous raw material for producing aluminosilicate phases. Thermal treatment of the waste at 1200°C for 30 min yields a material containing 50 wt.% mullite and exhibiting 96% overall crystallinity. The addition of amorphous silica significantly enhances mullite formation:
