Abstract: The present invention relates to a manufacturing apparatus and method for customizing a H2/CO synthetic gas in a desired ratio by producing a synthetic gas in which H2 and CO are mixed through hydrolysis of both carbon dioxide and a nitrogen compound with low power. In a low-power electrochemical apparatus for producing a synthetic gas according to the present invention, by performing the reduction of the carbon dioxide at the cathode and the oxidation of the nitrogen compound at the anode at the same time, carbon dioxide conversion efficiency may be improved 30% or more compared to the conventional carbon dioxide conversion system, and a synthetic gas with a desired H2/CO ratio may be produced by controlling the H2/CO ratio of the produced synthetic gas, and by reducing a driving voltage, the corrosion problem of electrode materials may be inhibited and the durability of electrodes may be increased.

Abstract: The present application relates to a method of preparing urate oxidase (Uox) including a non-nature amino acid (NNAA) and Uox prepared thereby. The present application showed that the method of preparing Uox including an NNAA may be effectively used to prolong the half-life of a protein which is difficult to be linked to a carrier.
In addition, the Uox produced by the method may be effectively used for various biopharmaceuticals since its efficacy is maintained and drug persistency increases due to site-specific conjugation of a carrier, a risk of an immune response is reduced, and it is easily separated due to formation of uniform conjugate.-

Abstract: The present inventive concept relates to a battery-free gas sensor or humidity sensor comprising a metal-organic framework and a method of manufacturing the same. In a photodiode-type battery-free gas sensor or humidity sensor according to the present inventive concept, since photoelectron collection electrodes are formed at certain intervals between P-N junction layers, when gas is adsorbed thereon, the gas can be detected without an extra power source by change of photocurrent. Due to fine pores of the metal-organic framework, gas sensitivity may be increased and stability of catalysts may be improved. When catalysts are not provided, humidity may be detected. Therefore, a system that used the photodiode-type battery-free gas sensor and the photodiode-type battery-free humidity sensor together may be performed humidity correction to accurately measure an amount of a gas.

Abstract: Disclosed are a temperature measurement method using the fluorescence characteristic of an optical material having temperature dependence and a temperature sensor technology using the same. According to the present disclosure, the temperature measurement technology using the fluorescence signal intensity ratio has a self-compensation function to reduce optical signal noise caused by fluctuations in light source output and optical waveguide loss, and uses two fluorescence signals with a strong fluorescence signal intensity to solve the existing disadvantage of generating a lot of noise due to a low fluorescence signal.
