Bio-vaterite formation by glycoproteins from freshwater pearls

Micron, 2010
A 48 kDa acidic and putative calcium-binding glycoprotein was isolated from pearls of the freshwater mussel Hyriopsis cumingii. This protein was compared with a related 46 kDa polypeptide, obtained from the nacreous shell of the same species. Separation by two-dimensional gel electrophoresis revealed that the difference in molecular weight is due to ...

Biotechnological Mineral Composites via Vaterite Precursors

MRS Proceedings, 2012
ABSTRACTVaterite is one of the thermodynamically less stable polymorphs of calcium carbonate. Under ambient conditions it transforms into calcite, the most stable form of calcium carbonate. Organisms are able to stabilize minerals such as vaterite by means of organic molecules.

Gallstone of Unusual Composition: Calcite, Aragonite, and Vaterite

Science, 1968
A gallstone of almost perfect octahedral symmetry was composed of a mixture of crystallites of the three polymorphous forms of calcium carbonate: calcite, aragonite, and vaterite.

Synthesis and Surface Modification of Birefringent Vaterite Microspheres

Langmuir, 2009
This paper reports on the synthesis of birefringent vaterite microspheres with narrow size distribution using a seeded growth method. In a post-treatment the microspheres were stabilized and functionalized through coating with a combination of organosilica and silica.

Vaterite from Ballycraigy, Larne, Northern Ireland

Mineralogical Magazine and Journal of the Mineralogical Society, 1960
SummaryVaterite, the third unstable polymorph of CaCO3, is recognized by optical and X-ray powder techniques as a major constituent in a carbonated calcium silicate hydrogel complex formed from larnite at Ballycraigy, Lame, Northern Ireland. Re-indexed X-ray powder data obtained on synthetic vaterite are provided indicating a hexagonal unit cell with ...
