The kinetics and mechanisms of amorphous calcium carbonate (ACC) crystallization to calcite, via vaterite.
TL;DR: The kinetics and mechanisms of nanoparticulate amorphous calcium carbonate crystallization to calcite, via vaterite, were studied at a range of environmentally relevant temperatures using synchrotron-based in situ time-resolved Energy Dispersive X-ray Diffraction (ED-XRD) in conjunction with high-resolution electron microscopy, ex situX-ray diffraction and infrared spectroscopy.

TL;DR: In this paper, high resolution transmission electron microscopy (HRTEM) observations point to polymorph selection by physicochemical (kinetic) factors (high supersaturation) and stabilization by organics, both connected with bacterial activity.

Precipitation of Calcite by Indigenous Microorganisms to Strengthen Liquefiable Soils
TL;DR: In this article, enrichment for indigenous microorganisms capable of hydrolyzing urea in the presence of CaCl2 was performed on potentially liquefiable saturated soils in both the laboratory and in situ.

TL;DR: A series of tests are documented in this article that demonstrate that natural indigenous bacteria can also be stimulated to induce calcite precip- itation with measurable changes in geotechnical properties.
Journal ArticleDOI
Cementation of porous materials using calcite
TL;DR: In this paper, a technique of cementing porous materials artificially using calcite is presented, which depends on flushing a mixture of chemical solutions through a porous medium, leading to precipitation of calcite due to reaction of the solution ingredients.

The solubilities of calcite, aragonite and vaterite in CO2-H2O solutions between 0 and 90°C, and an evaluation of the aqueous model for the system CaCO3-CO2-H2O
TL;DR: In this paper, the authors compared the solubility of calcite, aragonite, and vaterite in CO2-H2O solutions between 0 and 90°C using the Debye-Huckel individual ion activity coefficients.
Journal ArticleDOI
Electrolyte crystal growth mechanisms
TL;DR: In this article, it was shown that the rate of integration at a kink is of the order of one thousandth of the speed of dehydration of the cation, which is due to the activation energy of diffusion, as an ion, in order to integrate, must dehydrate and make a diffusional jump.

Vaterite growth and dissolution in aqueous solution. I, Kinetics of crystal growth
TL;DR: In this article, the growth kinetics of vaterite (CaCO3) from aqueous solution between about 10 and 45°C and at ionic strengths from 15mM to 315mM were determined by recording pH as a function of time and analysing these data by a BASIC computer program, correcting for complexes and using activity coefficients.
