Aragonite crystallization on functionalized styrene–butadiene copolymer

The inhibition of calcium carbonate crystal growth by the cysteine-rich Mdm2 peptide

“…The crystal surface contains active sites Table 3 Comparative data on the inhibition of calcite precipitation based on the ratio of the rate constants for adsorption and desorption, K aff = k a /k d with different energy such as kinks, steps, and terraces, but for the adsorption process only a small fraction of the available active sites are used with similar adsorption energy [22,32,[49][50][51]. The presence of Mdm2 in the supersaturated solutions only affect the crystallization kinetics of calcite, causing no changes in the mechanism of crystal growth or favoring the formation of another calcium carbonate polymorph such as aragonite [52], vaterite [53], or hydrated calcium carbonate [54,55]. Since Mdm2 peptide did not influence the crystallization of calcite, it is expected that it would cause a change in the electrokinetic parameters of calcite particles.…”

Effect of water chemistry on calcium carbonate deposition on metal and polymer surfaces

“…The sensitivity of aragonite formation to surface chemistry has been studied in the context of biomineralization. Researchers have selectively generated aragonite under Langmuir monolayers [45] and on polymer surfaces that have hydroxyl functionality [46][47][48]. While PP is not expected to form surface hydroxyls, some water will penetrate into the material and researchers have found weakened hydrogen bonding interactions between water molecules once they have diffused into PP [49].…”

Stabilities of crystal faces of aragonite (CaCO3) compared by atomic force microscopic observation of facet formation processes in aqueous acetic acid

“…3C was recorded for a wider area at a later stage of the dissolution. Troughs formed by (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) and (-112) facets were also observed. In total, four {112} facets were formed at the (001) surface.…”

“…[3][4][5][6] Aragonite is formed in shell nacre with (001) surface parallel to the substrates. 7 The processes can be partly mimicked by using synthetic polymers, 8,9 or thiol templates. 10,11 In inorganic and geological processes, aragonite is obtained when the solutions are alkaline, 12 the temperature is high, 13,14 the pressure is high, 15 Mg 21 concentration is high, [16][17][18] or when growth rates are high.…”
