The effects of pressure on immiscibility in metallic, core‐forming liquids: Implications for protoplanetary differentiation

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 720-738, April 2026.
Abstract Mechanisms for metal core formation in rocky planetesimals and planetary embryos remain poorly constrained, in part due to complexities arising from immiscibility in core‐forming liquids at low pressures. To assess the pressure dependence of immiscibility and its role in protoplanetary differentiation, we performed experiments at 3 and 5 GPa ...

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.

Tendencies of Soil Microbial NO Emissions During HI‐SCALE as Predicted by a Nitrification/Denitrification Scheme

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Many atmospheric chemical processes, including the formation of secondary organic aerosol (SOA), are strongly modulated by the reactions of NO and NO2NOx ${\text{NO}}_{2}\ \left({\text{NO}}_{x}\right)$. Though NOx ${\text{NO}}_{x}$ is controlled by anthropogenic emissions near urban areas, in rural areas soil microbes can be a significant ...
