Organic-template-directed nucleation of strontium fluoride and barium fluoride: Epitaxy and strain

Observation of a two-step mechanism in the formation of a superstructure of cadmium-behenic acid Langmuir monolayer: Evidence of an intermediate structure

“…Experiments on mineralization driven by Langmuir monolayer templates have been performed from either supersaturated or dilute salt solutions of divalent cations. In the first case, many works focus on the growth of oriented crystals of specific morphology [10][11][12]; recent in situ structural studies have investigated the commensuration between the lattices of the organic monolayer and the mineral [7][8][9]. For dilute salt solutions and fatty acid monolayers as organic templates, superlattice structures have been evidenced in the case of chloride salts of cadmium, lead, manganese, and magnesium [13][14][15][16].…”

“…Several studies investigate the nanoarchitecture and mechanical properties of natural organic-inorganic assemblies, such as nacre [2][3][4]. Simultaneously, model systems have been developed for testing biomineralization processes [5][6][7][8][9]. Among them, monolayers of amphiphilic molecules (Langmuir monolayers) at the interface of air-aqueous solutions of metal ions allow a systematic study of the mechanisms of surfactantmediated nucleation of the inorganic layer.…”

Complementary Control by Additives of the Kinetics of AmorphousCaCO3Mineralization at an Organic Interface:In-SituSynchrotron X-Ray Observations

“…For example, it is still widely quoted that fatty acid monolayers on a liquid surface can exert sufficient control over calcium carbonate mineralization to select the vaterite polytype and to orient the a-b face against the monolayer [5]. But in-situ synchrotron grazing-incidence diffraction failed to identify oriented mineral crystals [6], while time-resolved reflectivity measurements proved that the calcite and vaterite polytypes of CaCO 3 could be kinetically selected against fatty acid monolayers with identical structures [7]. Kinetics, then, is of critical importance for biomimetic mineralization.…”

Orientation and morphology of calcite nucleated under floating monolayers: A magnesium-ion-enhanced nucleation study

“…Previous studies examining heneicosanoic acid on subphases containing barium fluoride, lead carbonate, and other salts have found supercellular lattice matches and strained interfaces [23,24]. Applying the same techniques to common biominerals could be extremely informative; however, not much data is available, as pointed out recently in Ref.…”
