Mineral bridges in nacre revisited

  title={Mineral bridges in nacre revisited},
  author={Antonio G. Checa and Julyan H. E. Cartwright and Marc Georg Willinger},
  journal={arXiv: Biological Physics},
We confirm with high-resolution techniques the existence of mineral bridges between superposed nacre tablets. In the towered nacre of both gastropods and the cephalopod Nautilus there are large bridges aligned along the tower axes, corresponding to gaps (150-200 nm) in the interlamellar membranes. Gaps are produced by the interaction of the nascent tablets with a surface membrane that covers the nacre compartment. In the terraced nacre of bivalves bridges associated with elongated gaps in the…

Biomineralization is the process by which living systems produce minerals. At theEuropean scale, this particular scientific field associates researchers of diverse horizons,ranging from zoology,

Trochidae (Gastropoda) from the Sarmatian Basin of the Eastern Paratethys

The gastropod family Trochidae from the Sarmatian deposits of the Eastern Paratethys is described in detail. Detailed faunal characteristics of 22 Sarmatian sections in Volyn–Podolia, Moldova,

Nacre formation by epithelial cell cultures from mantle of the black-lip pearl oyster, Pinctada margaritifera

This study shows that mantle epithelial cells in culture retain the ability to secrete nacre and can therefore form the basis for future studies on the biomineralization process and its application in development of sustainable pearl culture.

Mineral bridges of nacre and its effects

Nacre, or mother-of-pearl, is a kind of composites of aragonite platelets sandwiched between organic materials. Its excellent mechanical properties are thought to stem from the micro architecture

Does Abalone Nacre Form by Heteroepitaxial Nucleation or by Growth through Mineral Bridges

We present experimental support for a model of abalone nacre growth that is based on mineral bridges between successive aragonite tablets rather than on heteroepitaxial nucleation. Interlamellar

The key role of the surface membrane in why gastropod nacre grows in towers

It is hypothesize that in gastropod nacre growth core formation precedes that of the interlamellar membrane, and the tower-like growth of gastropods nacre becomes comprehensible.

Study on microstructure and thermodynamics of nacre in mussel shell

An electron microscope study of the formation of the nacreous layer in the shell of certain bivalve molluscs

An electron-microscopic study was made of nacreous shell growth in several species of marine molluscs, showing that the first step in crystal formation is the “polymerization” of part of the pallial fluid to form lamellae parallel to the surface of the epithelium.
