Abstract: The present invention relates to a method for manufacturing a melt-spun nonwoven fabric and a microfiber nonwoven web manufactured therefrom. The present invention relates to a method for manufacturing a melt-spun nonwoven fabric, in which fibers obtained by melt-spinning a thermoplastic polymer through a spinning nozzle including at least one nozzle hole are collected by high-speed air stream, wherein the melt-spun fibers are subjected to momentary local heating at a high temperature higher than a spinning temperature while same are caused to pass through a nozzle local heating provided directly under the spinning nozzle during spinning, so that the method can lower the melt flow index and spinline elongation viscosity of a thermoplastic resin discharged from the nozzle hole without reducing a molecular weight, thereby providing a microfiber nonwoven web formed by finely thin fibers, compared to the conventional spun-bond nonwoven fabric.

Abstract: The present invention relates to a culture vessel for three-dimensional cell cultivation and a three-dimensional cell co-cultivation method using the same. The culture vessel comprises a well formed by a column positioned thereon and at least one support protruding from the column within the well. In contrast to conventional techniques, the present invention allows cells to be cultured at a position spaced from a culture vessel, thus enjoying the advantage of smoothly supplying oxygen necessary for three-dimensional cell culture structures.

Abstract: Provided are an apparatus for producing inorganic powder, and a method of producing inorganic powder by using such. The apparatus includes a vaporization part where a condensed-phase precursor is vaporized to obtain a gas-phase precursor, a partial precipitation part where the gas-phase precursor obtained in the vaporization part is partially precipitated to a condensed phase, and a reaction part where the gas-phase precursor remaining after being partially precipitated to a condensed phase in the partial precipitation part reacts with a reaction gas to obtain inorganic powder. An equilibrium vapor pressure of the gas-phase precursor in the partial precipitation part is lower than a vapor pressure of the gas-phase precursor obtained in the vaporization part, and an equilibrium vapor pressure of the precursor in the reaction part is equal to or higher than a vapor pressure of the gas-phase precursor partially precipitated to a condensed phase in the partial precipitation part.
