Enhanced rock weathering on managed land could become a meaningful carbon dioxide removal pathway before 2040, but only if removals can be verified. The difficulty is structural: durable removal is in...

Environmental policy; Environmental technology; Materials application

Soils show promising potential for carbon sequestration, with the capacity to store carbon in both organic (SOC) and inorganic (SIC) forms over extended timescales. Approaches including biochar additi...

Anelasticity in MgAl2O4 spinel due to cation order-disorder, Redfern, Simon, Walsh, Joanna

The structure of perovskite underpins materials from as deep as 2,900 kilometres in the Earth to those fundamental to modern technology, as Simon Redfern explains.

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...
