PURPOSE: A microchannel is provided to prevent a quenching phenomenon in the microchannel and to increase exothermic reaction while minimizing heat loss. CONSTITUTION: A thermoconductive device comprises: a channel body(110) transferring flames of a combustion reaction in a longitudinal direction; a fuel supply part transferring the combustion reaction material to the channel body. The heat-insulating layer(113) which is extended in the longitudinal direction and formed to a tubular shape; and a heat transfer layer(111) formed on the upper side of the inner side of the insulative layer. The anisotropy of heat transfer of the heat transfer layer is higher than the anisotropy of heat transfer in the longitudinal direction of the heat transfer layer in the direction perpendicular to the longitudinal direction.

PURPOSE: A particle separating apparatus and a method thereof are provided to effectively separate particles without losing any particle by squaring a force receiving direction with a direction of particle separation. CONSTITUTION: A particle separating apparatus comprises a channel unit(200) and an electrode unit(400). A first fluid and a second fluid flow together in the channel unit. The first fluid includes more than two types of carbon nano-particles. The second fluid flows near the first fluid. The electrode unit forms an electric field by arranging in one side of the channel section. The electrode unit is arranged to be next to the second fluid. At least part of particles included in the first fluid is separated from the first fluid and flows with the second fluid.

PURPOSE: A gas separating apparatus and a gas separating film are provided to improve thermal, mechanical, and electrical performance of the apparatus and to function as a filter which is specialized for preventing the penetration of water molecules. CONSTITUTION: A gas separating apparatus includes a gas inlet(210), a gas separating film(220), and a gas outlet(230). First gas containing vapor is introduced into the gas inlet. The gas separating film suppresses the penetration of vapor from the first gas. The gas separating film discharges second gas through the gas separating film. The gas separating film is based on vertically grown carbon nano-materials. The carbon nano-materials are based on one or more selected from carbon nano-wires, single-walled carbon nano-tubes, dual-walled carbon nano-tubes, and multi-walled carbon nano-tubes.
