The chemistry and genesis of opaque minerals in kimberlites

International Kimberlite Conference Extended Abstracts: 1973, 1975
Abstract Detailed electron-microprobe analyses of zonal trends in the spinel mineral group in kimberlites show that the early formed spinels are either highly enriched in the series picrochromite-chromite, or alternatively in the series MgAl2O4FeAl2O4; in both compositional types, progressive enrichment trends induced by solid-liquid or solid-gas ...

Coralline algae in a naturally acidified ecosystem persist by maintaining control of skeletal mineralogy and size [PDF]

, 2016
To understand the effects of ocean acidification (OA) on marine calcifiers, the trade-offs among different sublethal responses within individual species and the emergent effects of these trade-offs must be determined in an ecosystem setting.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.
