“…Complex structures found at the surfaces of leaves and butterfly wings are synthesized by chemical routes [4]. Xu et al [5] reviewed the biomimetic growth of inorganic materials and discussed the generation of complex structures with a specific size, shape, orientation, composition and hierarchical organization under ambient conditions in aqueous environments. Koumoto et al [6] summarized the bioinspired patterning of the ceramic thin films by surface modification techniques.…”

We review the solvothermal synthesis, using a mixture of ethylene glycol (EG) and water as the solvent, of zinc oxide (ZnO) particles having spherical and flower-like shapes and hierarchical nanostructures. The preparation conditions of the ZnO particles and the microscopic characterization of the morphology are summarized. We found the following three effects of the ratio of EG to water on the formation of hierarchical structures: (i) EG restricts the growth of ZnO microcrystals, (ii) EG promotes the self-assembly of small crystallites into spheroidal particles and (iii) the high water content of EG results in hollow spheres.

“…Calcite is a calcium carbonate (CaCO 3 ) polymorph important in many fields of science and technology ranging from being a component in animal skeletons [1][2][3], applications as fillers in polymers [4] or pigments in paints, and use as a catalysts [5] or substrates in chemical engineering. For many technological applications a precise control over the particle size, morphology and specific surface area would be highly desirable.…”

a b s t r a c tMolecular dynamics simulations were used to investigate possible explanations for experimentally observed differences in the growth modification of calcite particles by two organic additives, polyacrylic acid (PAA) and polyaspartic acid (p-ASP). The more rigid backbone of p-ASP was found to inhibit the formation of stable complexes with counter-ions in solution, resulting in a higher availability of p-ASP compared to PAA for surface adsorption. Furthermore the presence of nitrogen on the p-ASP backbone yields favorable electrostatic interactions with the surface, resulting in negative adsorption energies, in an upright (brush conformation). This leads to a more rapid binding and longer residence times at calcite surfaces compared to PAA, which adsorbed in a flat (pancake) configuration with positive adsorption energies. The PAA adsorption occurring despite this positive energy difference can be attributed to the disruption of the ordered water layer seen in the simulations and hence a significant entropic contribution to the adsorption free energy. These findings help explain the stronger inhibiting effect on calcite growth observed by p-ASP compared to PAA and can be used as guidelines in the design of additives leading to even more marked growth modifying effects.

“…Biomimetic approaches incorporating inorganic compounds and biological macromolecules are a driving force in development of novel advanced composite materials which exhibit unique physicochemical and material properties [1][2][3][4]. Biologically induced mineralization is based on selection and utilization of proper biomacromolecules which play a crucial role in nucleation, thermodynamic and kinetic crystal growth; and also can be used as a soft templates for inorganic structures [1].…”

range of uses. Here, chitin-based scaffolds isolated from the skeleton of marine demosponge Aplysina aerophoba were used as a template for the in vitro formation of iron oxide from a saturated iron(III) chloride solution, under hydrothermal conditions (pH~1.5, 90 °C). The resultant chitin-Fe 2 O 3 three dimensional composites, prepared for the first time via hydrothermal synthesis route, were thoroughly characterized using light, fluorescence and scanning electron microscopy; as well as with analytical methods like Raman spectroscopy, electron diffraction and HR-TEM. The results show that this versatile method allows for efficient chitin mineralization with respect to hematite. Additionally, we demonstrate that chitin nanofibers template the nucleation of uniform Fe 2 O 3 nanocrystals.
