Hidden pressure-stabilized lead reservoirs in Earth’s mantle - Nature Communications High-pressure Pb-S phases stable in Earth’s lower mantle provide a mechanism for long-term sequestration and episodic remobilization of lead, offering a plausible explanation for the missing lead para...

The "missing lead paradox" has been like having a history book with crucial pages torn out – we know something important is missing from our understanding of how Earth evolved.
In our new paper in Nature Communications, we propose a mineral-physics solution. www.nature.com/articles/s41...

Our latest research shows how calcium-based CO₂ sorbents degrade over time - crucial for scaling up carbon capture technology.
We found the sintering mechanisms limiting sorbent lifetime in calcium looping systems, paving the way for more durable materials.
