Discontinuous shear thickening in the presence of

2017-3-16  In the presence of dispersant molecules currently used in cement industry and based on polyethylene oxide (PEO), we found a strong discontinuous shear thickening (DST) at high volume fraction in suspensions of calcium carbonate particles. The transition was reversible and the critical shear rate and shear stress for which this instability appears are reported versus

Carbonate Mineral - an overview ScienceDirect Topics

Six bonds are made between the calcium with two oxygens in each of three carbonate groups and three shorter bonds with the corner oxygens of three other carbonate groups. The pseudohexagonal array has stacking order along ‘ c ’ of A(CO 3 ) 1 –B(CO 3 ) 2 –A(CO 3 ) 1 –B(CO 3 ) 2 , which results in orthorhombic symmetry.

Impact of Anthropogenic CO2 on the CaCO3 System in the

Rising atmospheric carbon dioxide (CO 2) concentrations over the past two centuries have led to greater CO 2 uptake by the oceans. This acidification process has changed the saturation state ofthe oceans with respect to calcium carbonate (CaCO 3) particles.Here we estimate the in situ CaCO 3 dissolution rates for the global oceans from total alkalinity and chlorofluorocarbon
