Geochemistry of Monazite within Carbonatite Related REE Deposits

open access: yesResources, 2017
Approximately >50% of global rare earth element (REE) resources are hosted by carbonatite related deposits, of which monazite is one of the most important REE minerals. Monazite dominates more than 30 carbonatite-related REE deposits around the world,

Recent Advances in Hafnium Oxide Nanomaterials: From Controlled Synthesis, Structure, and Surface Engineering to Biomedical Applications

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Hafnium oxide (HfO2) nanoparticles (NPs), derived from a rare‐metal element, have gained increasing attention as a versatile class of functional nanostructures with unique optical, dielectric, and surface properties that enable diverse biomedical applications. As a representative rare‐metal oxide, HfO2 NPs with well‐defined architectures offer

Fluorite Composition Constraints on the Genesis of the Weishan REE Deposit, Luxi Terrane

open access: yes
Fluorite, a key accessory mineral associated with rare earth element (REE) deposits, exerts a significant influence on REE migration and precipitation through complexation, adsorption, and lattice substitution within fluorine-bearing fluid systems.

The sympathoregulatory region of the mouse rostral brainstem relies on both GABA and glycine to generate inhibitory currents

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 2939-2957, 1 April 2026.
Abstract figure legend Our study demonstrates that both GABA and glycine mediate inhibitory postsynaptic currents in the ventrolateral/ventromedial medulla (VLM/VMM) and increasing the activity of inhibitory synapses facilitates glycine release. We found that presympathetic VLM/VMM neurons receive glycinergic inputs, which release both glycine and GABA,

A New Concept for an Integrated Mapping of Rare‐Earth Elements using Laser–Induced Fluorescence and Reflectance Spectroscopy

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
We introduce a new integrated line‐scan sensor system that combines hyperspectral and laser‐induced fluorescence imaging as a non‐invasive alternative characterization technique specifically suited for rare‐earth element (REE) mapping and identification. We investigate in detail the potential and limitations in comparison to state‐of‐the‐art approaches

Data‐Driven Insights into Rare Earth Mineralization: Machine Learning Applications Using Functional Material Synthesis Data

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 2, February 2026.
Hydrothermal synthesis records for rare‐earth compounds are repurposed to learn mineralization rules. An extreme gradient boosting model ingests precursors, additives, and engineered descriptors to predict product phases, crystallization temperature, and pH. Feature importance indicates dominant thermodynamic control with kinetic modulation, suggesting

PHOSPHATE-FLUORIDE-CARBONATE MINERALIZATION IN LAMPROITE ROCKS OF THE RYABINOVY PLUTON (CENTRAL ALDAN): MINERALOGICAL AND GEOCHEMICAL FEATURES AND ORIGIN [PDF]

open access: yesМинералогия, 2017
Carbonate and apatite-fluorite mineral assemblages are studied in lamproite rocks from high-K Ryabinovy intrusive (Central Aldan, Russia). It is concluded that these assemblages are genetically related and belong to the same apatite-fluorite-carbonate ...
