Green Approach in Synthesis of Bio-Inspired Materials

摘要: In this Special Issue, we focus on biomineralization/pathological biomineralization systems and the synthesis of bioinspired materials. This Special Issue promotes the current trend of “green chemistry”, and, as such, in all published papers, only aqueous solutions and eco-friendly additives were used for the production of well-characterized bioinspired materials.This Special Issue contains four papers: three original research papers and one review. Here, a brief introduction of these papers is provided. Kontrec et al.[1] in their paper indicate a significant contribution of initial pH to the overall effect of all parameters relevant to precipitation processes and biomineralization. This paper reports on the influence of initial pH and type of stirring on the kinetics, phase composition, size, and morphology of spontaneously precipitated calcium carbonate (CaCO3). CaCO3 is one of the most widespread biominerals formed via biomineralization in calcifying organisms. Precipitation processes are the physicochemical basis of biomineralization. The main parameter controlling the precipitation of CaCO3 is supersaturation, but other parameters, such as the concentration of constituent ions and dissolved carbon dioxide (CO2)[2], the presence of additives [3, 4], temperature [5], pH [6], ionic strength [7] and hydrodynamics [8], are also known to influence and control CaCO3 precipitation and, consequently, together with the variety of biological constituents and processes, influence biomineralization. Bearing in mind that the supersaturation, ionic strength, and activity ratio of constituent ions a (Ca2+)/a (CO3 2−) influence the phase composition and morphology of the …
