The disclosed methods enable zirconium sulfophenyl phosphonate, zirconium sulfate, or zirconia sulfate, which has high performance as a proton conducting material and high catalytic activity, to be produced at low temperature by reaction by adding sulfophe...

Provided is a long-distance target detection camera system capable of detecting/tracking a target widely from a long distance to a short distance while simplifying the structure. The long-distance target detection camera system for detecting a long-distanc...

The subject of the present invention is to provide a nuclear reactor plant of which is a direct cycle nuclear reactor using a carbon dioxide as a coolant such that a heat evacuation for liquefying coolant is reduced while a compressive work is reduced by u...

A first reactive solution is made of a water solution composed of LiOH·7HO melted in distilled water, and a second reactive solution is made of a water solution composed of CoSO · 7HO melted in distilled water. Then, the first and the second reactive sol...

A blended solution is made by melting LiOH.H2O into distilled water, and then, Co metallic powders are added into the blended solution to make a reactive solution. The reactive solution is charged into an autoclave, and held at a predetermined temperature....

A reactive solution with an amount of 250 mL is made of distilled water and LiOH.H2O (4M) melted in the distilled water. Then, the reactive solution is put in a flow-type reactor, and is flown in between an anode electrode and a cathode electrode set in th...
