    　View Summary

    To create a coating of titanium nitride, atmospheric-controlled induction-heating fine particle peening using fine particles of pure titanium was conducted for low-alloy steel in a nitrogen atmosphere, and the surface characteristics of the treated specimens were investigated. The formation of hard titanium nitride coatings with a thickness of 100–200 μm was achieved by peening at 1373 K for 10 s and subsequent heating at 1373 K for 120 s. Titanium particles adhered to the treated surfaces during peening at the high temperature, which reacted with nitrogen in the atmosphere during the heating after peening. Ball-on-disk wear tests were conducted to examine the wear resistance of the specimens, and it was found that the created coating by AIH-FPP improved the wear resistance of low-alloy steel owing to its high hardness. The improvement was more significant at high testing temperatures because the high testing temperature and frictional heat caused oxygen in the air to react with titanium in the coating during the wear test. Immersion of the specimens into sodium chloride solution was also conducted to investigate the corrosion resistance, which revealed that the coating created improved corrosion resistance of low-alloy steel.

  • Metallic Vessel with Mesh Culture Surface Fabricated Using Three-dimensional Printing Engineers Tissue Culture Environment

    　View Summary

    Various culture devices have been developed as fundamental technologies for facilitating bioengineering studies. Culture devices are designed to prepare specific culture environments. Thus, both macrostructures and surface micromorphology should be considered in the device design. Although fabricating devices with elaborate designs incurs high production costs, disposable materials are typically used for culture devices. However, some metallic materials are strong, stable, and biocompatible. Bioengineers have not applied these materials to culture devices because of the difficulty of processing. An emerging technology using three-dimensional (3D) printing has been developed, which can produce complex designs using metal. We demonstrate the applicability and potential of metal 3D printing for fabricating culture devices toward the development of the bioengineering discipline. As a specific example, we fabricated metallic culture devices where the environment of cultured tissues can be improved. One of the biggest factors determining the culture environment is active media supply. To attain active media supply to the tissue, devices having culture surfaces with mesh structures having holes far larger than cells were proposed. Cell sheets were cultured as tissue models, realizing tissue culture with such structures. The cultured tissue showed increased metabolism, indicating enhanced media supply owing to mesh surfaces. The biocompatibility of the 3D printed metal device was confirmed by viability assays on cultured cells, and reusability of the device was confirmed by mechanical and biochemical evaluations. We believe this study serves as a reference for using metallic 3D printing as an option for fabricating culture devices, which will promote bioengineering research.

  • Titanium Culture Vessel Presenting Temperature Gradation for the Thermotolerance Estimation of Cells

    　View Summary

    Hyperthermia can be induced to exploit the thermal intolerance of cancer cells, which is worse than that of normal cells, as a potential noninvasive cancer treatment. To develop an effective hyperthermia treatment, thermal cytotoxicity of cells should be comprehensively investigated. However, to conduct such investigations, the culture temperature must be accurately regulated. We previously reported a culture system in which the culture temperature could be accurately regulated by employing metallic culture vessels. However, appropriate temperature conditions for hyperthermia depend on the cell species. Consequently, several experiments need to be conducted, which is a bottleneck of inducing hyperthermia. Hence, we developed a cell culture system with temperature gradation on a metallic culture surface. Michigan Cancer Foundation-7 cells and normal human dermal fibroblasts were used as cancer and normal cell models, respectively. Normal cells showed stronger thermal tolerance; this was because the novel system immediately exhibited a temperature gradation. Thus, the developed culture system can be used to investigate the optimum thermal conditions for effective hyperthermia treatment. Furthermore, as the reactions of cultured cells can be effectively assessed with the present results, further research involving the thermal stimulation of cells is possible.
