Discrete element method for investigating the borehole wall rock failure process based on the enhancement effect of microbial drilling fluids

Petroleum
Borehole wall instability in unconsolidated formations is a critical challenge in drilling engineering and requires urgent attention. Microbially induced calcium carbonate precipitation (MICP) is a promising solution for reinforcing unstable formations ...

Dopamine-Induced Mineralization of Calcium Carbonate Vaterite Microspheres

, 2016
Two biogenic materials from mussels are attracting attention from scientists: calcium carbonate (CaCO3), the most widely studied biomineral that composes the shell, or nacre, of mussels, and dopamine, a small catechol-containing biomimetic molecule of ...

Hydrothermal Synthesis and Characterization of Ideal Vaterite-Type Lanthanide Orthoborates

Single crystals of lanthanide orthoborates containing Nd, Sm, Eu, Gd, and Tb, which crystallize in the vaterite structure, were synthesized via a subcritical hydrothermal method. NdBO3 has not previously been reported in the vaterite structure, and other

Research Progress on Vaterite Mineral and Its Synthetic Analogs

As the most unstable crystalline form of calcium carbonate, vaterite is rarely found in nature due to being highly prone to phase transitions. However, its high specific surface area, excellent biocompatibility, and high solubility properties have led to

Vaterite: a mineralization product of the hard tissues of a marine organism (Ascidiacea)

, 1975
X-ray diffraction and infrared absorption spectra show that the spicules of the common tropical ascidian, Herdmania momus, are mineralized with vaterite. These are the first strictly marine organisms known to normally precipitate vaterite.
