The reactions of dolomite with portlandite have been studied at well-spaced temperatures between 20 degrees C and 85 degrees C using XRD Rietveld, TG and SEM methods. The results show quantitatively the faster rates of reaction at higher temperature. Isoth ...
We present a series of molecular dynamics simulations of the shock compression of copper matrices containing a single graphite inclusion: these model systems can be related to some specific carbon-rich rocks which, after a meteoritic impact, are found to c ...
Calcium-containing slag material is produced in iron- and steelmaking worldwide, including Finland. One process route utilizing this calcium, being developed towards large-scale application, is the so-called slag2pcc concept. Using ammonium salts, up to 50 ...

Species of Haliotis (abalone) show high variety in structure and mineralogy of the shell. One of the European species (Haliotis tuberculata) in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Microbial Induced Calcite Precipitation (MICP) is an innovative technique for soil grouting in which injected bacteria supplemented with chemicals lead to calcite precipitation in soils. A comprehensive research work is carried out to better understand and ...
Calcite is among the most abundant minerals on earth and plays a central role in many environmental and geochemical processes. Here we used amplitude modulation atomic force microscopy (AFM) operated in a particular regime to visualize single ions close to ...
A BaCO3 slurry, containing radioactive C-14, is produced during the reprocessing of spent nuclear fuel. This slurry is encapsulated in a Portland-blastfurnace slag composite cement. The effect of BaCO3 on the hydration of OPC and Portland-blastfurnace slag ...
Species of Haliotis ~abalone! show high variety in structure and mineralogy of the shell. One of the European species ~Haliotis tuberculata! in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
ABSTRACT Scleractinian corals begin their biomineralization process shortly after larval settlement with the formation of calcium carbonate (CaCO3) structures at the interface between the larval tissues and the substrate. The newly settled larvae exert var ...
Deep saline aquifers have a great potential for geologic carbon dioxide (CO2) sequestration and proper assessment of host and cap rock is needed to guarantee that the procedure is safe. Temperatures and pressures at which most of the possible host rocks ex ...
