Inhibition 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 کاملShock temperature in calcite (CaCO3) at 95^160 GPa
The temperatures induced in crystalline calcite (CaCO3) upon planar shock compression (95^160 GPa) are reported from two-stage light gas gun experiments. Temperatures of 3300^5400 K are obtained by fitting six-channel optical pyrometer radiances in the 450^900 nm range to the Planck gray-body radiation law. Thermodynamic calculations demonstrate that these temperatures are some 400^1350 K lower...
متن کاملSHOCK TEMPERATURES IN CALCITE (CaCO3): IMPLICATION FOR SHOCK INDUCED DECOMPOSITION
The temperatures induced in crystalline calcite upon planar shock compression (95-160 GPa) are reported from two-stage light gas-gun experiments. The temperatures are obtained fitting 6channel optical pyrometer radiances in the 450 to 900 nm range, to a Planck radiation law temperature varied from 3300 to 5400 K. Calculations demonstrate that the temperatures are some 400 to 1350 K lower than i...
متن کاملSHOCK INDUCED VAPORIZATION OF ANHYDRITE CaS04 AND CALCITE CaCO3
Discovery of abundant anhydrite (CaS04) and gypsum (CaS0+2HzO) in the otherwise carbonate sediments comprising the upper portion of the rocks contained within the Chicxulub impact crater has prompted research on the shock-induced vaporization of these minerals. We use a vaporization criterion determined by shock-induced entropy. We reanalyze the shock wave experiments of Yang [ 11. He shocked 3...
متن کاملPreparation of porous apatite granules from calcium phosphate cement.
A versatile method for preparing spherical, micro- and macroporous (micro: 2-10 and macro: 150-550 microm pores), carbonated apatitic calcium phosphate (Ap-CaP) granules (2-4 mm in size) was developed by using NaCl crystals as the porogen. The entire granule production was performed between 21 and 37 degrees C. A CaP cement powder, comprising alpha-Ca3(PO4)2 (61 wt.%), CaHPO4 (26%), CaCO3 (10%)...
