Energies of the Adsorption of Functional Groups to Calcium Carbonate ...
网页2013年8月6日 · The adsorption energies for the alcohols are typical of chemisorption and indicate alcohol displacement of water from calcium carbonate surfaces. This explains why organisms favor biomolecules that contain alcohol functional groups (−OH) to control which polymorph they use, the crystal face and orientation, and …
Simulating the binding of key organic functional groups to aqueous ...
网页2021年11月30日 · In this study, the coordination of small organics that contain the two most relevant functional groups for biomineralisation of calcium carbonate, namely carboxylate and ammonium, with the corresponding mineral ions are examined in aqueous solution.
CaCO 3 products formed on various functional group substrates
网页Various functional groups have been suggested to play essential roles on biomineralization of calcium carbonate (CaCO3) in natural system. 2D and 3D models of regularly arranged...
Calcium carbonate crystallization controlled by functional groups…
网页2013年1月16日 · Various functional groups have been suggested to play essential roles on biomineralization of calcium carbonate (CaCO 3) in natural system. 2D and 3D models of regularly arranged functional groups have been established to investigate their effect on CaCO 3 crystallization. This mini-review summarizes the recent progress and the future ...
Calcium carbonate: controlled synthesis, surface …
网页In the process, calcite acted as a catalyst for the catalytic carbonization of biochar and contributed toward changes in yield, pH, texture, and the surface functional groups of the CaCO 3 –biochar composites. For the calcite–biochar composites, calcite formed a stronger bond with Pb under alkaline conditions.
网页ABSTRACT: Various functional groups have been suggested to play essential roles on biomineralization of calcium carbonate (CaCO3) in natural system. 2D and 3D models of regularly arranged...
Energies of the Adsorption of Functional Groups to Calcium Carbonate ...
网页2013年8月6日 · The adsorption energies of calcium carbonate, the main component of the calcareous deposits, are typical chemisorption for hydroxyl functional groups (-OH), resulting in the strong...
Two competitive nucleation mechanisms of calcium carbonate ...
网页2015年8月17日 · The present study presents a clear CaCO 3 biomineralization pathway by introducing biomimetic surfaces terminated with four types of common functional groups in nature. Ion adsorption mechanism is proved to be reasonable on strongly negative-charged −COOH surface in low calcium condition.
Ab initio and metadynamics studies on the role of essential functional …
网页2014年10月22日 · This paper presents ab initio and metadynamics studies of the interactions of Ca 2+, CO 3 2−, and water with the essential amino acids/functional groups, e.g. arginine/NH 2 +, aspartate or glutamate/COO −, aspartic or glutamic acid/COOH, and serine/OH, of protein/organic molecules that are likely to …
Thermal assisted self-organization of calcium carbonate
网页2018年12月6日 · Our results demonstrate that self-organized heterotextured architectures of calcium carbonate can be fully controlled with high level of complexity and precision.
