In this work crystallization kinetics of hydroxyapatite (HAP) were investigated in the presence of a biodegradable, environmentally friendly polysaccharide-based polycarboxylate, carboxymethyl inulin (CMI), under strictly controlled temperature, pH, and atmospheric conditions. The constant-composition method has been used to study the influence of biopolymers of crystal growth of HAP, on HAP seed crystals at pH 7.4 and 37°C. The results indicate that polymer concentration and the larger number of negatively charged functional groups markedly affect the growth rate. Biopolymer affects the coherence length of the crystalline domain. The decrease in growth rates was substantiated by SEM which showed smaller crystal sizes as a function of increasing carboxylation degree of the CMI and its concentration.

“…This is true for both ordered and amorphous calcium carbonate phases (39). Changes in the organic surface charge (38,40), degree of structural similarity to the crystal (41), and ordering of water molecules adjacent to the surface (42) can each alter the interfacial energy of the template, and change the dynamics of nucleation. The presence of Na and Mg at the organic template surface can influence each of the surface properties that contribute to interfacial energy.…”

Plankton, corals, and other organisms produce calcium carbonate skeletons that are integral to their survival, form a key component of the global carbon cycle, and record an archive of past oceanographic conditions in their geochemistry. A key aspect of the formation of these biominerals is the interaction between organic templating structures and mineral precipitation processes. Laboratory-based studies have shown that these atomic-scale processes can profoundly influence the architecture and composition of minerals, but their importance in calcifying organisms is poorly understood because it is difficult to measure the chemistry of in vivo biomineral interfaces at spatially relevant scales. Understanding the role of templates in biomineral nucleation, and their importance in skeletal geochemistry requires an integrated, multiscale approach, which can place atom-scale observations of organic-mineral interfaces within a broader structural and geochemical context. Here we map the chemistry of an embedded organic template structure within a carbonate skeleton of the foraminifera Orbulina universa using both atom probe tomography (APT), a 3D chemical imaging technique with Ångström-level spatial resolution, and time-of-flight secondary ionization mass spectrometry (ToF-SIMS), a 2D chemical imaging technique with submicron resolution. We quantitatively link these observations, revealing that the organic template in O. universa is uniquely enriched in both Na and Mg, and contributes to intraskeletal chemical heterogeneity. Our APT analyses reveal the cation composition of the organic surface, offering evidence to suggest that cations other than Ca 2+ , previously considered passive spectator ions in biomineral templating, may be important in defining the energetics of carbonate nucleation on organic templates. biomineralization | templating | foraminifera | geochemistry | paleoceanography

“…Hydrophilic anion groups such as OH -and COOH -in biomacromolecules on the cell wall surface can improve the mineralization ability of yeast cells and regulate crystal nucleation and growth [45]. In fact, hydrophilic anion groups also exist inside the yeast cell, and they are from nucleic acid and proteins.…”

Its capacity is far higher than the capacity of unsubstituted LFP and LVP in the same wide voltage range. The energy density of this cell is about 4 times higher than that of modern commercial lithium-ion batteries (157 Wh kg -1 ). The wide voltage range not only increases the discharge capacity and energy density of cathode materials, but also could expand the range of its applications in electronic equipment.3
