Subliquidus glass-glass immiscibility along the albite-diopside join

, 1983
A calorimetric study has shown that glasses along the albite-diopside join in the system albiteanorthite-diopside have positive enthalpies of mixing.

Accounting for retarded weathering products in comparing methods for quantifying carbon dioxide removal in a short-term enhanced weathering study

Frontiers in Climate
Various approaches are currently used to quantify the carbon dioxide removal (CDR) associated with enhanced weathering (EW), which involves amending soils with crushed silicate minerals.

Cost effective red emitting Eu3+ doped natural sodium feldspar (NaAlSi3O8) powder and photophysical changes on transition to glassy state

Results in Optics, 2023
There is a need for low cost red emitting materials for commercial phosphor converted white light emitting diodes (pc-WLEDs) due to low color rendering index (CRI) and high correlated color temperature (CCT) of currently existing InGaN pumped YAG:Ce3 ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
