Adding lime to agricultural soils can remove CO2 from the atmosphere, rather than cause CO2 emissions, claims new research.

One type, however, known as a pallasite meteorite is very different. They are made of olive-green crystals that are composed ...

It’s certainly not an obvious choice as a source for battery materials. But that’s exactly how it’s viewed by a group of New Zealand engineers. Christchurch-based Aspiring Materials has developed a ...

Salt silicate is a family of inorganic compounds composed of differing ratios of salt oxide (Na ₂ O) and silicon dioxide (SiO ...

Astronomers have observed thick, mineral-rich clouds, potentially containing iron, enveloping the young exoplanet YSES-1b, leading to the possibility ...

Magnesium silicate hydrate cement (MSHC), as an innovative low-carbon cementitious material, is considered a potential substitute for ordinary Portland cement (OPC). However, uncertainties in the ...

The US Food and Drug Administration is seeking information about the health risks of talc, or hydrous magnesium silicate, in food and drugs. Manufacturers voluntarily removed the common mineral ...

The scientists also exposed the wet samples of calcium silicate and magnesium oxide directly to air, which has a much lower concentration of CO2 than pure CO2 from a tank.

In a lab test where the calcium silicate and magnesium oxide were exposed to water and pure CO 2, the two materials transformed into carbonate minerals with carbon trapped inside within just two ...

Stanford researchers developed a scalable method to permanently remove CO2 from the atmosphere using heat-activated minerals. Their kiln-based process transforms silicates into materials that ...

Kanan and his colleague Yuxuan Chen, also at Stanford University, have developed a way to produce magnesium oxide and calcium silicate using a process inspired by cement production.
