Exploration of the role of heat activation in enhancing serpentine carbon sequestration reactions
…to an amorphous component that preferentially forms at higher temperatures. The aqueous carbonation reaction process was investigated for representative materials via in situ synchrotron X-ray diffraction. Magnesite was observed to form directly at 15 MPa…

Magnesium hydroxide extracted from a magnesium-rich mineral for CO2 sequestration in a gas-solid system
Magnesium hydroxide extracted from magnesium-bearing minerals is considered a promising agent for binding CO2 as a carbonate mineral in a gas-solid reaction. An efficient extraction route consisting of hydrothermal treatment on serpentine in HCl…

Sorption of nonpolar aromatic contaminants by chlorosilane surface modified natural minerals
…headgroups and chemical properties. Silanol groups of the diatomite and zeolite were modified by chemical reaction with the chlorosilanes resulting in a stable covalent attachment of the organosilanes to the mineral surface. The alteration of surface…
