DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Biomineralization refers to the biological process through which highly ordered inorganic materials with hierarchical structures are formed in living organisms. Currently, the mechanisms of biomineralization remains largely unknown. In this work, we used AFM  to track the mineralization process of magnesium containing amorphous calcium carbonate (MgACC). The lipid templating method was used to synthesize and stable the MgACC for more than fifteen hours. For a longer setting time of lipid-MgACC in the solution, high Mg-calcite was also observed. The XRD and FT-IR measurements showed that lipid-MgACC powder would transform to high Mg-calcite during the aging process without heating and solvent. HR-TEM and SAED were used to characterize the fringes of Mg-calcite in this aging process. The nano-sized crystallinities of Mg-calcite could self-assemble to form spherical particles of 20 m with aging. Focused ion beam milling and dark field TEM imaging were performed to observe the amorphous region and highly co-orientated nano-crystallites of Mg-calcite inside the microspheres. From Ca-L edge XANES and low temperature crystallization peak as revealed by the TGA-DSC measurements, we infer that lipids helped remove the structure water of Mg-ACC in the aging process. On the basis of all the experimental data, it is suggested that the Mg-calcite crystallization process occurred via the solid-state transformation pathway. We hypothesize that lipid bound Mg-containing nanoparticles were extruded with the structure water and formed the lecithin organogel fiber. The fibers were highly adhesive for the spherical Mg-calcite. As the aging time increased, the microspheres of Mg-calcite aggregated along the fiber and consequently fused to form the long spicule. Lastly, chiral morphology of calcium carbonate was obtained in agarose gel in the presence of aspartic acids, demonstrating the versatile morphology of calcium carbonate.
