Olivine/melt partitioning of the transition metal cations, Fe2+, Mn2+, Co2+, and Ni2+, together with Mg2+ and Ca2+, has been examined experimentally as a function of melt composition at ambient ...

Stanford figures out how to make rocks absorb carbon 1,000 times faster than nature The new process uses common minerals in kilns to absorb CO2 quickly and efficiently. Updated: Mar 03, 2025 08:25 ...

Specifically, the calcium silicate and magnesium oxide only needed two hours to complete their CO 2 extractions. Open Air test To test the new material in a more realistic environment. The team ...

The catch is that unlike magnesium-based minerals, calcium silicates aren’t naturally abundant. So, the researchers had to find an efficient way to make them. They combined calcium oxide (CaO) with ...

For a more realistic test, wet samples of calcium silicate and magnesium oxide were exposed directly to air, which has a much lower concentration of CO 2 than pure CO 2 from a tank. In this experiment ...

An article recently published in the journal Nature introduced an innovative method for removing atmospheric carbon dioxide (CO2) through thermal calcium/magnesium ion (Ca2+/Mg2+) exchange reactions.
