摘要： Disclosed are partially deactivated metal catalysts useful for modifying structures of nanomaterials. The present invention is also directed to a method for preparing the partially deactivated metal catalysts, which comprises patterning a substrate with micelles containing iron nanoparticles, removing the micelles from the patterned substrate to deposit the iron nanoparticles thereon, nitriding the iron nanoparticles using a nitrogen plasma, and exposing the nitrided iron nanoparticles to a mixture of ethanol and nitric acid to remove iron from the surface of the nitrided nanoparticles. The iron nitride metal catalyst with a nano-size according to the present invention comprises a core that includes deactivated iron nitride and an active shell surrounding the core. Thus, when preparing a carbon nanotube, the metal catalyst can be effectively used to control the number of walls formed in the carbon nanotube.

摘要： An electromagnetic control valve having a permanent magnet and a needle are fitted in a cylindrical valve body, and a coil, and first and second yokes are mounted on an outside circumferential surface of the valve body. There are first and second ports in the valve body for making an outside space and an inside space of the valve body in communication. There is an orifice in the valve body for making the first and the second ports in communication. The needle is disposed at a position opposite to a side of the orifice, for moving in an up/down direction when a current is applied to the coil. Direction and amount of movement of the needle are dependent on a direction and an intensity of the current applied to the coil. When the needle moves, a tip of the needle varies an opened area of the orifice linearly, according to which a flow rate of the fluid passed through the orifice is controlled according to a position of the needle.
