Abstract: Disclosed is a method for manufacturing a 3D printing structure, the method including: producing a molded body by performing 3D printing on paste including printing powder in a coagulation bath including a hydrogel; hardening the molded body produced in the coagulation bath; and removing the hydrogel in the coagulation bath. A method for manufacturing a 3D printing structure, which is provided according to an aspect of the disclosure, does not require printing of a separate support, and thus it is possible to save time and costs. A post-processing process for removing a support is not required. Thus, a process is further simplified, and there is no risk of damage to a structure.

Abstract: A method of manufacturing a p-type MOSFET includes depositing a channel material to form a channel region, forming a source region and a drain region on each side of the channel region along a first direction, depositing a gate oxide layer on the channel region along a second direction crossing the first direction, and depositing a gate electrode on the gate oxide. The channel material includes a group IV element or III-V semiconductor compound and have a diamond or zincblende cubic crystal structure. A <001> direction of the crystal structure is parallel to the second direction. Two adjacent atoms on an out-most atomic layer of the channel region along the first direction are connected to each other via a single intervening atom, and an interface between the gate oxide layer and the channel region has a surface roughness of 1 angstrom or lower.

Abstract: A composition includes a hydrogel that includes a plurality biodegradable natural polymer macromers crosslinked with a first agent and optionally a plurality of cells dispersed in the crosslinked macromers, the microgels are capable of being crosslinked with a second agent that is different than the first crosslinking agent.

Abstract: The present invention provides an ionically cross-linkable alginate-grafted hyaluronate compound containing alginate and hyaluronate, the alginate and the hyaluronate forming a covalent linkage. The use of the compound can easily provide a cross-linked hyaluronate by adding a divalent cation without using a chemical cross-linking agent. The present invention also provides a method for cell transplantation that includes preparing a composition comprising the compound of claim 1 and cells for transplantation, and administering to a subject in need thereof the composition.
