A method for producing a metal catalyst having an inorganic film deposited thereon by means of an atomic layer deposition (ALD) process, and a metal catalyst according to the method are disclosed. More specifically, the method includes a step of inducing selective adsorption of reactants to a portion having a low coordination number on the surface of the catalyst in the ALD process, thereby being intended to induce interaction between the catalyst and an inorganic film layer and maximally secure active sites of the catalyst.

An atomic layer deposition (ALD) method in an ALD reactor including a reaction chamber housing a substrate vessel, and an isolated vibration source outside of the reaction chamber or isolated within the reaction chamber. Particulate material within the substrate vessel is coated by self-saturating surface reactions using a top-to-bottom precursor flow passing through the substrate vessel, and movements are caused in the particulate material within the substrate vessel by the isolated vibration source while coating the particulate material.

Techniques are disclosed for systems and methods to provide magnetic carbon nanotube clusters configured to form electrically conductive coatings. A magnetic carbon nanotube cluster is formed by receiving a magnetic particle, forming a plurality of carbon nanotube catalyst nanoparticles on an outer surface of the magnetic particle, and forming a plurality of carbon nanotubes extending from the catalyst nanoparticles while the magnetic particle is levitated within a nanotube growth chamber to form the magnetic carbon nanotube cluster. A plurality of magnetic carbon nanotube clusters are suspended in a carrier fluid, the carrier fluid is flowed over a surface of an object, and a magnetic field is applied to the carrier fluid while it is flowing over the surface to cause the plurality of magnetic carbon nanotube clusters to form a coating on the surface of the object.

The electronic component has a protective film formed over the entire surface thereof, and the electronic component has elements and wirings formed on a base body. The protective film is formed by a CVD method, over an entire surface of the electronic component, by: arranging an electrode in a chamber; grounding one side of the chamber and the electrode; accommodating the electronic component in the chamber; supplying a raw material gas to the chamber; rotating or swinging the chamber and thereby moving the electronic component in the chamber; supplying high-frequency power to the other side of the chamber and the electrode; and generating a raw-material-gas-based plasma between the electrode and the chamber.

The manufacturing method for a graphene film includes steps of: providing a porous material powder; placing the porous material powder in an atomic layer deposition device; forming a porous material template having a metal catalyst layer in pores; and preparing the graphene film on the porous material template.

A powder coating apparatus includes: a reactor configured to rotate and improve reactivity of powder accommodated therein; a rotating unit including a roller positioned at a lower portion of the reactor and configured to rotate while in direct contact with the reactor and cause the reactor to rotate; and a chamber unit configured to at least partially accommodate the reactor and the rotating unit and create a predetermined environment for a deposition reaction of the powder inside the reactor. The chamber unit includes an openable/closable lid to allow the reactor to be replaced with a new reactor. Since a fastening portion is not present in the powder coating apparatus itself, full automation in which a mass production reactor is separated from the chamber unit and transferred to a holder by a robot arm is facilitated. Thus, time until a subsequent process is reduced, and product yield can be increased.
