Rapid terrestrial weathering of the CI1 carbonaceous chondrite find Oued Chebeika 002

Meteoritics &Planetary Science, Volume 61, Issue 2, Page 211-223, February 2026.
Abstract Alteration of historic CI1 meteorite falls during their curation demonstrates the susceptibility of smectite‐rich carbonaceous chondrites to terrestrial exposure. The discovery of Oued Chebeika 002 in Morocco in June 2024 presents a unique opportunity to document the earliest stages of weathering of a CI1 find.

A “Cool” Route to Battery Electrode Material Recovery

Advanced Energy Materials, Volume 15, Issue 46, December 9, 2025.
Ice‐stripping, a novel sub‐zero electrode delamination technique, enables >90% recovery of the electrode materials from manufacturing scrap and end‐of‐life batteries. Water is sprayed upon a porous electrode and quickly freezes when placed on a cold surface. The foil is peeled away, leaving behind the black mass with the morphology retained.

Restoration of human tooth enamel

BMEMat, Volume 3, Issue 4, December 2025.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...
