Accelerating Mineral Carbonation Using Carbonic Anhydrase
Environmental Science & Technology, 2016Carbonic anhydrase (CA) enzymes have gained considerable attention for their potential use in carbon dioxide (CO2) capture technologies because they are able to catalyze rapidly the interconversion of aqueous CO2 and bicarbonate. However, there are challenges for widespread implementation including the need to develop mineralization process routes for ...

Carbon mineral ecology: Predicting the undiscovered minerals of carbon
American Mineralogist, 2016Studies in mineral ecology exploit mineralogical databases to document diversity-distribution relationships of minerals—relationships that are integral to characterizing “Earth-like” planets. As carbon is the most crucial element to life on Earth, as well as one of the defining constituents of a planet’s near-surface mineralogy, we focus here on the ...

Reviews in Mineralogy and Geochemistry, 2013
The discovery of the extreme antiquity of specific minerals through radiometric dating (e.g., Strutt 1910), coupled with Norman L. Bowen’s recognition of a deterministic evolutionary sequence of silicate minerals in igneous rocks (Bowen 1915, 1928), implies that Earth’s crustal mineralogy has changed dramatically through more than 4.5 billion years of ...

Mycorrhizae enhance reactive minerals but reduce mineral‐associated carbon
Global Change Biology, 2023AbstractSoil organic carbon (C) is the largest active C pool of Earth's surface and is thus vital in sustaining terrestrial productivity and climate stability. Arbuscular mycorrhizal fungi (AMF) form symbioses with most terrestrial plants and critically modulate soil C dynamics.

Ex Situ Aqueous Mineral Carbonation
Environmental Science & Technology, 2007The U.S. Department of Energy's National Energy Technology Laboratory (NETL) located in Albany, OR (formerly the Albany Research Center) has studied ex situ mineral carbonation as a potential option for carbon dioxide sequestration. Studies focused on the reaction of Ca-, Fe-, and Mg-silicate minerals with gaseous CO2 to form geologically stable ...

Lysozyme mediated calcium carbonate mineralization
Journal of Colloid and Interface Science, 2009Lysozyme, a major component of egg white proteins, has been speculated to participate in the calcification of avian eggshells. However, its detailed role during the eggshell formation is not well understood. In this work, the influence of lysozyme on the precipitation of CaCO(3) has been investigated using a combined study of FTIR, XRD, and SEM.

Carbon dioxide disposal in carbonate minerals
Energy, 1995Abstract We introduce a safe and permanent method of CO2 disposal based on combining CO2 chemically with abundant raw materials to form stable carbonate minerals. Substantial heat is liberated in the overall chemical reaction so that cost will be determined by the simplicity and speed of the reaction rather than the cost of energy.
