Fast crystallization altered microlite and melt composition in a Hunga bomb
This research indicates that fast microlite crystallization can create compositional trends in melt that may look like pre-eruptive fractional crystallization, making some volcanic samples unreliable for reconstructing reservoir processes.

Heteroleptic carbones show varied bond strength changes
This research indicates that heteroleptic carbones can have bent or, in two cases, linear equilibrium structures, and that their bond strengths relative to homoleptic species do not follow a direct bond-length correlation.
