Sodium‐based, geopolymer foamed composites reinforced with phosphate mine waste particulates and hemp/basalt fibers

Journal of the American Ceramic Society, EarlyView.
Abstract This study investigated the mechanical, microstructural, and thermal properties of Na‐based geopolymer foams (GPFs) reinforced with varying amounts of two types of reinforcements: raw phosphate mine waste rock (PMWR) as a particulate filler, and natural (hemp) or synthetic (basalt) fibers.

The Influence of Spatial Extent and Distance on Macroinvertebrate‐Environment Relationships in Conterminous USA Stream Sites

Journal of Biogeography, EarlyView.
ABSTRACT Aim The relationships between environmental variables and macroinvertebrate assemblages depend on spatial extent, but the relative importance of local and regional factors remains unclear. Understanding these scale‐dependent relationships is crucial for improving biodiversity assessments and ecosystem management.

Calibration, Validation and Evaluation of Machine Learning Thermobarometers in Metamorphic Petrology: An Application to Biotite and Outlook for Future Strategy

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Geothermobarometry provides crucial constraints on the physical conditions of metamorphism, offering insights into petrogenetic processes and providing key information on thermal regimes and metamorphic depths to other geological disciplines.
