[193] In addition to prismatic calcite, sea urchin teeth represent another example with multiple crystalline features, where the polycrystalline calcite matrix show higher modulus, hardness, and crack resistance than the single-crystal calcite fibers and plates; higher concentrations of Mg in the polycrystalline matrix also contributed to the property enhancement.

Biomineralized composites, which are usually composed of microscopic mineral building blocks organized in 3D intercrystalline organic matrices, have evolved unique structural designs to fulfill mechanical and other biological functionalities. While it has been well recognized that the intricate architectural designs of biomineralized composites contribute to their remarkable mechanical performance, the structural features within and corresponding mechanical properties of individual mineral building blocks are often less appreciated in the context of bio-inspired structural composites. The mineral building blocks in biomineralized composites exhibit a variety of salient intracrystalline structural features, such as, organic inclusions, inorganic impurities (or trace elements), crystalline features (e.g., amorphous phases, single crystals, splitting crystals, polycrystals, and nanograins), residual stress/strain, and twinning, which significantly modify the mechanical properties of biogenic minerals. In this review, recent progress in elucidating the intracrystalline structural features of three most common biomineral systems (calcite, aragonite, and hydroxyapatite) and their corresponding mechanical significance are discussed. Future research directions and corresponding challenges are proposed and discussed, such as the advanced structural characterizations and formation mechanisms of intracrystalline structures in biominerals, amorphous biominerals, and bio-inspired synthesis.

“…Such materials could be used for bone implants, for example, and in the long term, could represent a sustainable alternative to the energy-intensive ceramic processes. In this project, the newly developed biomimetic synthesis approach, a layer-by-layer process, is particularly suited to generate analogous crystallographic gradients and bioactive coatings for biomedical implants in an energy efficient synthesis [ 33 , 34 , 35 ].…”

Biomimetic research has increased over the last decades, and the development process has been systemized regarding its methods and tools. The aim of biomimetics is to solve practical problems of real-life scenarios. In this context, biomimetics can also address sustainability. To better understand how biomimetics research and development can achieve more sustainable solutions, five projects of applied research have been monitored and analyzed regarding biological models, abstracted biological principles, and the recognition of the applied efficiency strategies. In this manuscript, the way in which sustainability can be addressed is described, possibly serving as inspiration for other projects and topics. The results indicate that sustainability needs to be considered from the very beginning in biomimetic projects, and it can remain a focus during various phases of the development process.

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.
