Calcium carbonate is a chemical compound with the formula CaCO 3 formed by three main
elements: carbon, oxygen, and calcium. It is a common substance found in rocks in all parts …

In this review we report the most recent applications of nanotechnology to the conservation
and restoration of the world's cultural heritage. Nanoparticles of humble calcium and …

Atomistic simulation techniques have been employed to investigate the effect of molecular
adsorption of water on the low-index surfaces of calcite, aragonite, and vaterite. Calculated …

Small block copolymers, consisting of a hydrophilic poly (ethylene glycol) block and a
second hydrophilic moiety which strongly interacts with alkaline earth ions, were employed …

Construction of organic− inorganic hybrid materials with controlled mineralization analogous
to those produced by nature is now of current interest for both organic and inorganic …

Spherical and polycrystalline particles of vaterite precipitated from solution has been shown
to grow by crystal growth of a spherulitic type, and not by aggregation of nano-sized …

Raman spectroscopy was used to study vaterite samples of biological, geological and
synthetic origin. The Raman band positions and the full width at half‐maximum (FWHM) of …

Crystallization of CaCO3 in the presence and the absence of half-generation poly
(amidoamine)(G n. 5 PAMAM) dendrimers was carried out by a double jet method to prevent …

The kinetics of transformation of vaterite to calcite in aqueous solution was studied at
temperatures between 25° C and 45° C and ionic strengths between 15 and 415 mmol dm …

Biogenic calcium carbonate derived from waste shells has received significant attention in
the last 2 decades as a replacement for limestone due to its contribution to reducing …
