Mechanical strength of amorphous CaCO3 colloidal spheres.
Amorphous glassy CaCO3 colloidal spheres of monomodal size distribution were studied by high-resolution Brillouin light scattering. The Young modulus of 37 GPa and shear modulus of 14 GPa of glassy CaCO3 at a density of 1.9 g/cm3 were extracted from the particle vibration frequencies by employing acoustic wave scattering cross-section calculations. The line shape of the low-frequency modes is a...
متن کاملMixing Precipitation of CaCO3 in Natural Waters
The mixing precipitation of CaCO3 in natural waters was theoretically studied by the methods of chemical equilibrium calculation. Results show that mixing precipitation of CaCO3 can be produced by mixing between two unsaturated water samples with respect to CaCO3, two oversaturated water samples, an unsaturated water sample and an oversaturated water sample. Mixing precipitation can be classifi...
متن کاملInhibition by glycosaminoglycans of CaCO3 (calcite) crystallization.
Of a range of glycosaminoglycans, heparin and heparan sulphate were the most effective inhibitors in vitro of CaCO3 (calcite) crystallization as assayed by conductimetric measurements. The possible role of such glycosaminoglycans in modulating calcium-salt crystallizations in vivo is discussed.
متن کاملSimulation of Structural Transformation in Aragonite CaCO3
The structural transformation in aragonite CaCO3 is simulated by molecular dynamics. The simulations are based on the potentials calculated from the Gordon-Kim modified electron gas formalism. We found two phase transitions in aragonite at high temperature.
