“…3, several continuous peaks present the bond vibrations of the ZrO 2 and C-N/ZrO 2 -x (x = 1, 2, 3, 4, 5) composites at 410.8 cm À1 , 501.5 cm À1 , 580.5 cm À1 , and 762.8 cm À1 , which correspond to the stretching modes of Zr-O-Zr vibrations. 29,30 The broadband around 3433 cm À1 indicates the stretching of O-H bonds. In contrast with ZrO 2 , two exclusive infrared absorption peaks of composites appear at 1556.4 cm À1 and 1621.0 cm À1 , which are the stretching vibration peaks of the carbon-nitrogen aromatic heterocyclic ring.…”

“…According to the obtained results, it can be found that both PNFs and CaNFs play important role in guiding the crystal nucleation and final formation of ZrO 2 NPs during the biomimetic mineralization of the hybrid materials. Compared with other methods for the preparation of ZrO 2 NPs, such as hydrothermal synthesis [ 39 ], sol-gel synthesis [ 40 ], and microwave-assisted combustion [ 41 ], the biomimetic mineralization method in this work has the advantages of simplicity, economy, and green, and shows more application prospects in many fields.…”

Carbon nanofibers (CaNFs) exhibit promising applications in the fields of environmental science and nanotechnology, and self-assembled peptide nanofibers (PNFs) are useful for the biomimetic synthesis of organic-inorganic hybrid nanomaterials and the fabrication of functional hybrid membranes for the removal of various pollutants from water. In this work, we report the biomimetic synthesis of hybrid nanomaterials by the interweaving of CaNFs and PNFs. Using the biomimetic mineralization properties of PNFs, ZrO2 nanoparticles were synthesized along the nanofiber surface, and then functional nanohybrid porous membranes were prepared by the vacuum filtration technology. For the fabrication of membranes, the amount of PNFs and ZrO2 precursors in the hybrid membrane were optimized. The designed organic-inorganic hybrid membranes exhibited high removal performance for fluorine ion (F−) from water, and the removal efficiency of the fabricated membranes towards F− ion-containing aqueous solution with a concentration of 50–100 mg/L reached more than 80%. In addition, the nanofiltration membranes revealed good adsorption capacity for F− ions. It is expected that the strategies shown in this study will be beneficial for the design, biomimetic synthesis, and fabrication of nanoporous membranes for economic, rapid, and efficient water purification.

“…[3][4][5][6][7] Because of its tetragonal structure, 3 mol% yttria-stabilized ZrO 2 (3YSZ) has excellent mechanical properties, and its room temperature bend-ing strength has reached 1000 MPa or more. 8,9 With the development of nanotechnology, the refinement of nano-ZrO 2 ceramic grains promotes the number of grain boundaries greatly, improving the strength, toughness, and plasticity of the material. Nano-ZrO 2 is called "ceramic steel" due to its high strength corresponding with metal.…”

This paper introduces a new method for adjusting the particle size of ZrO 2 powder through the electric field effect of tourmaline. The 3 mol% yttriastabilized ZrO 2 (3YSZ) powder was prepared by using ZrOCl 2 •8H 2 O, YCl 3 •6H 2 O, NaOH, and nano-tourmaline powder as raw materials through direct precipitation. The powder was characterized with thermogravimetric-differential scanning calorimeter, X-ray diffraction, Brunauere-Emmette-Teller, Fourier transform infrared, scanning electron microscope, and transmission electron microscope, and the mechanism of tourmaline in the process of powder preparation was also discussed. Findings demonstrate that the electric field generated by spontaneous polarization of tourmaline can control the size of ZrO 2 crystal grains, improve the dispersibility of the powder, and promote the stability of ZrO 2 in the tetragonal phase. When the electric intensity of tourmaline is 9.02 × 10 6 V/m, and the addition amount is 2.5 vol%, tourmaline/3YSZ powders are mainly tetragonal phase, and the grain size is the smallest, with an average crystallite size of 19 nm. Then the mechanical properties of tourmaline/3YSZ ceramics were tested. Compared with 3YSZ ceramics without tourmaline, the flexural strength and fracture toughness were improved by 39.5% and 35.8%.
