This application relates to a hoisting tool for small-sized seedlings, belonging to the field of seedling hoisting. The device includes two symmetrical connecting rods, which are rotatably connected to a rotating rod via a pivot. The surfaces of the two rotating rods are rotatably connected via the pivot. A chain is provided on the rear side of each rotating rod, and a fixing block is provided at the top of the rear rotating rod. A slidable sliding pin is provided through the right side of the surface of the fixing block. One end of the chain is fitted onto the surface of the sliding pin. Circular columns are fixedly connected to both the front and rear sides of the sliding pin, and a circular block is fixedly connected to the bottom of the sliding pin. This application allows the connecting rods, rotating rods, and arc-shaped clamps to work together, enabling the two arc-shaped clamps to directly clamp small soil balls, wrap the chain around the surface of the tree trunk, and then, through the cooperation of hooks, sliding pins, and circular columns, the two ends of the chain are hooked onto the surfaces of the hooks and circular columns, thus securing the chain.

The present invention relates to a micelle complex and a drug carrier. By supporting hydrophobic manganese oxide particles in the micelles, the complex is stably protected in vivo and easily delivered to a tumor site. Further, the micelles have a hydrophilic portion and a hydrophobic portion bound by a reactive oxygen species (ROS) cleavable linker in order to be degraded in response to a reactive oxygen species of a target site, and thus can efficiently release the hydrophobic manganese oxide particles. The released hydrophobic manganese oxide particles generate oxygen and changes the microenvironment of the target site, and thus may enhance the therapeutic effect of a drug carried on the micelles.

The disclosure in the present specification relates to a fuel cell membrane humidifier comprising: a main housing; a hollow fiber membrane cartridge comprising a seal mount formed on an end of a cartridge housing so as to protrude, and a fixing layer for potting multiple membranes on both side ends of the body thereof, the hollow fiber membrane cartridge being installed inside the main housing; an inlet housing comprising a coupling portion mounted on a inlet connecting portion of the main housing, a seal ground portion formed inside the coupling portion, and a main chamber into which dry air is supplied through a cooler; an outlet housing comprising a coupling portion connected to an outlet connecting portion of the main housing, a gas inflow port through which gas is provided from a hydrogen fuel cell stack, a second chamber in which humid air formed through the membranes flows, and a cartridge insertion portion to which one side end of the cartridge housing is coupled; a variable seal comprising a body elastically grounded to the outer peripheral surface of the seal mount, and a rib elastically deformed with respect to the body portion and forced against the seal ground portion; and a back pressure passage extending between the main chamber and the seal ground portion. The ground pressure of the rib against the seal ground portion is formed to increase in response to the pressure of dry air in the main chamber introduced through the back pressure passage when the dry air is supplied.

The present invention relates to a metal nanowire having a core-shell structure, the metal nanowire being conductive and transparent while having excellent oxidation stability, and being capable of maintaining excellent oxidation stability even after a secondary process using the metal nanowire of the present invention. Specifically, the metal nanowire having a core-shell structure, according to the present invention, comprises a core containing copper, and a shell containing silver on the core, wherein the ratio (D / L) of the diameter (D) of the core to the thickness (L) of the shell is 10-60, the thickness of the shell is 5-40 nm, and the peak intensity (I1) of Ag 3d5 / 2 of silver and the peak intensity (I2) of Cu 2p3 / 2 of copper in the X-ray photoelectron spectrum satisfy the following Equation 1. I2 / I1≤0.2
