Abstract Biological materials have excellent mechanical properties due to their organized structures from nano- to macro-scale. Artificial manufacture of materials with anisotropic microstructures still remains challenging. We described a stress-induced method to fabricate anisotropic alginate fibers. Organic-inorganic composite fibers were obtained by incorporating aligned hydroxyapatite (HAP) nanowires into the alginate fiber. Detailed structural characterization revealed the bone-like structu...

Abstract A series of transparent ceramics with the composition of Al(8+x)/3O4−xNx (x = 0.299–0.575) were prepared without any sintering additives by presintering combined with hot isostatic pressing (HIP). The composition of the samples was accurately determined to investigate the effect of nitrogen content on optical properties in γ-AlON. The samples with x = 0.299–0.510 possessed excellent in-line transmittance (>80 %) from the visible light to middle-infrared wavelengths, which was attributed...

Abstract A new quaternary Li0.19Al2.72O3.64N0.36 transparent ceramic with the Vickers hardness of 17.91 ± 0.2 GPa at a load of 9.8 N and the in-line transmittance of 83.4% at 3.5 µm was prepared by hot isostatic press sintering (HIP) after pressureless sintering. The 7Li and 27Al magic-angle spinning (MAS) NMR spectra combined with the XRD Rietveld refinement was adopted to analyze the crystal structure. It is revealed that all the lithium ions are located in octahedra and the cation vacancies a...

ABSTRACT On the basis of the bond valence model, a new prediction model of thermal expansion coefficient for cubic inorganic crystals using a simple formula is presented. The bond linear thermal expansion coefficient is introduced as a parameter deduced by bond valence and bond length, and can directly describe the thermal expansion of chemical bonds. For cubic multibond crystal systems, the linear thermal expansion coefficient can be obtained by an average of the linear thermal expansion coeffi...

Tooth enamel is composed of arrayed fluorapatite (FAP) or hydroxyapatite nanorods modified with Mg-rich amorphous layers. Although it is known that Mg2+ plays an important role in the formation of enamel, there is limited research on the regulatory role of Mg2+ in the synthesis of enamel-like materials. Therefore, we focus on the regulatory behavior of Mg2+ in the fabrication of biomimetic mineralized enamel-like structural materials. In the present study, we adopt a bioprocess-inspired room-tem...

Abstract As one of the most delicate bioprocesses in nature, biosilicification is closely related to biosilica with various morphologies, and has provided abundant inspiration to materials synthesis. In the present study, to explore the biosilica formation process and fabricate silica with an exquisite microstructure for lithium-ion battery (LIB) electrodes, a bacterial phage (M13) is used as a biotemplate to synthesize silica with diverse morphologies: cylinders, hexagonal prisms, assemblies of...

Abstract null null The seven-layer B4C/TiB2-based graded composites was prepared with B4C and Ti–Al intermetallics through stepped laminating processing and transient liquid phase spark plasma sintering. The sintering strategy of the graded composites was proposed based on the sintering products of monolayer materials with different contents of Ti–Al intermetallics from 5 wt% to 60 wt%. The top three layers and bottom three layers were sintered respectively at 1650 °C and 1500 °C, and then the m...

Collagen fibrils present periodic structures, which provide space for intrafibrillar growth of oriented hydroxyapatite nanocrystals in bone and contribute to the good mechanical properties of bone. However, there are not many reports focused on bioprocess-inspired synthesis of non-native inorganic materials inside collagen fibrils and detailed forming processes of crystals inside collagen fibrils remain poorly understood. Herein, the rapid intrafibrillar mineralization of calcium fluoride nanocr...

Motility is significant in organisms. Studying the influence of motility on biological processes provides a new angle in understanding the essence of life. Biomineralization is a representative process for organisms in forming functional materials. In the present study, we investigated the biomineralization of iron oxides templated by Escherichia coli (E. coli) cells under oscillation. The formation of iron oxide minerals with acicular and banded morphology was observed. The surface charge of E....

Abstract Due to the application in transparent windows, armors and domes, it is essential to have a deep insight into the mechanical properties of spinel-type MgAlON solid solution. Mg5xAl23−5xO27+5xN5−5x were chosen for the investigation of composition-dependent mechanical properties via combining first-principles calculations with bond valence models. The calculated mechanical properties showed a consistence with experimental values, supporting the validity of the investigation. The simulated ...
