Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to gain a solid appreciation for the special significance of the world of modern biomimetics as well as the rapid and exciting evolution and expansion of extreme biomimetics and its applications in modern technology and medicine. This Special Issue is planned as a source on extreme (psychrophilic and thermophilic) as well as forced biomineralization, the solvothermal and hydrothermal chemistry of metal oxides and nanostructured composites, and bioinspired materials science for research in a variety of areas. Special attention will be paid to communities of organisms that survive extreme environmental conditions such as in Antarctic waters, hydrothermal vents, and geothermal pipelines. The discussion of the principles of extreme biomimetics with respect to the carbonization of biological scaffolds as well as metallization of chemically and thermally stable biopolymers is also welcome. For the first time, such current concepts as hierarchical organization of hydrothermally or psychrophilic obtained biocomposites, structural bioscaffolds, biosculpturing, biomimetism, and bioinspiration as tools for the design of innovative materials can be critically analyzed from both a biological and materials science point of view using numerous unique examples from nature and the lab.

Biological substrates catalyze the nucleation and growth of sparingly soluble salts however, the underlying mechanism is largely unknown. In the present study, the growth of calcium carbonate (CaCO3), on Acutodesmus obliquus (AO) microalgae was investigated. The test microalgae favored the growth of CaCO3 from solutions supersaturated with respect to calcite (7.94 < SRcalcite < 104.71). The precipitation of calcite on AO was not preceded by measurable induction times, and the rates of calcite crystal growth were higher for higher microalgae cell concentrations. The presence of the microalgae cultivation medium and illumination of the supersaturated solutions accelerated the precipitation of CaCO3, increasing the rate by 75% in comparison with the respective value in its absence. AO cultures, air dried at 25 °C yielded higher precipitation rates, in comparison with the respective rates in the presence of active AO cultures. At 70 °C, nucleation and growth were suppressed, due to the destruction of the molecular structure of the microalgae. The CaCO3 precipitation rates on calcite precipitated on air-dried AO culture, were doubled in comparison with the respective rates obtained with the respective quantities of each component of the composite substrate.
