Abstract: According to an embodiment of the present invention, an emergency core cooling system (ECCS) valve provided between a reactor vessel of a system-integrated modular advanced reactor (SMART) and a small containment vessel formed to surround the reactor vessel so that a coolant is filled in a space between the reactor vessel and the small containment vessel in the event of a loss of coolant accident (LOCA) includes an outer shell connected to the reactor vessel and formed to protrude toward the small containment vessel and having a connector formed therein so as to communicatively connect an inside of the reactor vessel to an inside of the small containment vessel, an inner shell provided inside the outer shell at a preset distance from an inner wall of the outer shell, a piston movably constrained and inserted through a piston opening formed in the inner shell at a position facing the connector of the outer shell to open and close the connector, and a spring provided on an outer circumferential surface of the p

Abstract: An inductor includes a first magnetic body having a toroidal shape and having a ferrite; and a second magnetic body configured to be different from the first magnetic body and including a metal ribbon, wherein the second magnetic body includes an outer magnetic body disposed on an outer circumferential surface of the first magnetic body and an inner magnetic body disposed on an inner circumferential surface of the first magnetic body, and each of the outer magnetic body and inner magnetic body is wound in a plurality of layers in a circumferential direction of the first magnetic body.

Abstract: Provided are a method for fabricating a human nasal turbinate-derived mesenchymal stem cell-based 3D bioprinted construct, and a use thereof, wherein the human nasal turbinate-derived mesenchymal stem cell-based, 3D bioprinted construct is advantageous over conventional mesenchymal stem cell-based, 3D bioprinted constructs in that the former can survive and proliferate stably in vitro and/or in vivo and shows high osteogenic differentiation ability as well, therefore is expected to make a great contribution to the practical use of cellular therapeutic agents.

Abstract: Nanoreactors having a metal precursor in a carrier are provided. In some embodiments, upon exposure to heat, the metal precursor forms nanoparticles that can be detected, e.g., by detecting a color change in the nanoreactor and/or by detecting the number and/or size and/or size distribution and/or shape of the nanoparticles. The nanoreactors can be used, in some embodiments, as time-temperature indicators for perishable goods.

Abstract: Methods of detecting very low levels of targets, such as cells, are provided. In some embodiments, for example, the methods can detect bacteria present in a sample at concentrations less than 25 cells/mL. The method involves detecting nanoparticle aggregation in the absence of the target.
