A method of preparing a carbon fiber including: preparing a precursor fiber for preparing a carbon fiber; and stabilizing the precursor fiber. The stabilization of the precursor fiber includes a first stabilization phase, a second stabilization phase, a third stabilization phase, and a fourth stabilization phase, which are set at four different temperatures between a temperature at which heat starts to be generated from the stabilization reaction of the precursor fiber and a temperature at which the generation of heat is maximized. Ozone gas is input while at least one phase of the third stabilization phase and the fourth stabilization phase is carried out.

A thermoelectric module that has excellent thermal, electric properties, can realize high joining force between thermoelectric elements and an electrode, and can maintain stable joining even at a high temperature.

Thermoelectric module

A thermoelectric module including at least a first and a second thermoelectric element comprising a thermoelectric semiconductor; an electrode connecting the first and second thermoelectric elements; and at least a first and a second joining layer, the first joining layer positioned between the first thermoelectric element and the electrode, and the second joining layer positioned between the second thermoelectric element and the electrode; and at least a first and a second barrier layer including an alloy including Cu, Mo and Ti, the first barrier layer positioned between the first thermoelectric element and the first joining layer, and the second barrier layer positioned between the second thermoelectric element and the second joining layer. The module prevents heat diffusion of the material of the joining layer, preventing the oxidation and deformation of the thermoelectric element under high temperature environment, and exhibiting improved operational stability due to excellent adhesion to a thermoelectric element.

The present invention relates to an organozinc-supported catalyst, a method for producing the same, and a method for preparing a polyalkylene carbonate resin using the catalyst. The organozinc-supported catalyst provided by the present invention includes a zinc dicarboxylate-based catalyst supported on a zinc compound layer formed on at least a portion of a support surface, and can be used repeatedly or continuously while exhibiting improved selectivity in the polymerization process for preparing a polyalkylene carbonate resin.
