“…5). The interfacial free energy between the cluster and a solution is usually larger than that between the cluster and a solid substrate, resulting in crystal nucleation at solid surfaces rather than within the solution itself (De Yoreo and Velikov, 2003). If the atomic structure of a substrate matches a particular plane of the nucleating phase (e.g.…”

a b s t r a c t a r t i c l e i n f oIn this paper, we review the current understanding of biomineralization in perforate foraminifera. Ideas on the mechanisms responsible for the flux of Ca 2+ and inorganic carbon from seawater into the test were originally based on light and electron microscopic observations of calcifying foraminifera. From the 1980s onward, tracer experiments, fluorescent microscopy and high-resolution test geochemical analysis have added to existing calcification models. Despite recent insights, no general consensus on the physiological basis of foraminiferal biomineralization exists. Current models include seawater vacuolization, transmembrane ion transport, involvement of organic matrices and/or pH regulation, although the magnitude of these controls remain to be quantified. Disagreement between currently available models may be caused by the use of different foraminiferal species as subject for biomineralization experiments and/or lack of a more systematic approach to study (dis)similarities between taxa. In order to understand foraminiferal controls on element incorporation and isotope fractionation, and thereby improve the value of foraminifera as paleoceanographic proxies, it is necessary to identify key processes in foraminiferal biomineralization and formulate hypotheses regarding the involved physiological pathways to provide directions for future research.

“…Likely, the disinclination to heterogeneously nucleate on substrate surfaces resulted from the higher nucleation energy barrier of smooth surfaces. [18] Therefore, we designed a new growth method based on a cavitation-triggered asymmetrical crystallization (CTAC) strategy, which would promote heterogeneous nucleation by providing enough energy to overcome the nucleation barrier. Briefly, we introduced a very short ultrasonic pulse (~ 1 s) to the solution when it reached a low supersaturation level with antisolvent vapor diffusion (See Experimental Session).…”

“…Soluble additives can strongly influence calcite morphologies through preferential association with the acute or obtuse step edges, or pinning of step movement. 43 45 The effect of Asp on calcite growth has been particularly well studied, where preferential binding to the acute step edges ultimately gives rise to elongated particles with highly roughened sides, that are capped at each apex with three, smooth {104} faces. 13, 46 At higher supersaturations and additive concentrations calcite can also form polycrystalline particles.…”

Soluble additives are widely used to control crystallization, leading to definition of properties including size, morphology, polymorph and composition. However, due to the number of potential variables in these experiments, it is typically extremely difficult to identify reaction conditions -as defined by solution compositions, temperatures and combinations of additives -that give the desired product. This article introduces a high throughput methodology which addresses this challenge and enables the streamlined preparation and characterization of crystalline materials. Using calcium carbonate precipitated in the presence of selected amino acids as a model system, we use well plates as micro volume crystallizers, and an accurate liquid handling pipetting workstation for sample preparation. Following changes in the solution turbidity using a plate reader delivers information about the reaction kinetics, while semi automated scanning electron microscopy, powder XRD and Raman microscopy provide structural information about the library of crystalline products. Of particular interest for the CaCO3 system is the development of fluorescence based protocols which rapidly evaluate the amounts of the additives occluded within the crystals. Together, these methods provide a strategy for efficiently screening a broad reaction space, where this can both accelerate the ability to generate crystalline materials with target properties, and develop our understanding of additive directed crystallization.
