摘要： A hydrogel for cell-laden bioprinting, bioink, and a preparation method and an application thereof, relates to the technical field of biomedical polymer hydrogels. The hydrogel for cell-laden bioprinting is polymer gel formed by adding a cell-specific material into a matrix of alginate and gelatin and crosslinking and curing, wherein the cell-specific material is polypeptide selected according to different laden cells. The structures printed using the hydrogel may have the advantages such as adjustable mechanical properties, adjustable porosity, high biocompatibility, high printing accuracy, and high customizability, which may widely support the printing of human tissues and organs such as spinal cord, cartilage, and heart, and has good prospects for applications in tissue repair, organ transplantation and so on.

摘要： A method of rapid constructing human cerebral cortical organoids by 3D bioprinting and an application including preparing microfluidic chips, preparation of hydrogel of human cerebral cortical organoids, and printing of human cerebral cortical organoids. The microfluidic chip comprises a mixed-flow channel layer, liquid pool layer, microporous array layer, human cerebral cortical organoid culture layer, and culture medium recovery layer; the human cerebral cortical organoid hydrogel has gelatin, alginate, and hyaluronic acid; printing directly human cerebral cortical organoids in microfluidic chips by FRESH printing method, obtaining human cerebral cortical organoid chips after packaging. The application directly constructs large-scale human cerebral cortex-like with three layers of mutually connected structures in situ in organ chip through 3D bioprinting, simulates cerebrospinal fluid circulation through perfusion culture.

摘要： An alumina-based ceramic tool material with low thermal expansion and a preparation process thereof, accordingly, the ceramic tool material may have both the high hardness of alumina ceramics after the hot pressing sintering, and reduces the thermal expansion coefficient of the overall ceramic material by adding the Sc2W3O12 as the negative thermal expansion phase, which improves the thermal shock resistance of ceramic tools in high-speed cutting engineering and meets the requirements of large temperature range during the machining of nickel-based superalloys. Moreover, the composite material does not use metal binder and has strong thermal stability even in the high-speed machining under extreme heat-force-chemistry coupling, so it has a high machining compatibility for nickel-based superalloys.
