Abstract: An operating method is disclosed for a dehydrogenation reaction system. The method includes providing a system having: an acid aqueous solution tank including an acid aqueous solution; a dehydrogenation reactor including a chemical hydride of a solid state and receiving an acid aqueous solution from the acid aqueous solution tank to react the chemical hydride with the acid aqueous solution to generate hydrogen; and a fuel cell stack receiving hydrogen generated from the dehydrogenation reactor to be reacted with oxygen to generate water and simultaneously to generate electrical energy. The method also includes recycling the water generated from the fuel cell stack to one or all of the acid aqueous solution tank, the dehydrogenation reactor, and a separate water tank. The acid is formic acid and, in in the dehydrogenation reactor, the temperature is in a range of 10° C. to 400° C. and the pressure is in a range of 1 bar to 100 bar.

Abstract: Provided is a modular experiment automation system including a main computer, a material synthesis module, and a material analysis module. The main computer interacts with a material synthesis module and a material analysis module. Upon a start request, it provides synthesis instructions for a target material. Once synthesis is complete, it instructs the analysis module to analyze the material. Based on the analysis results, if the error exceeds a threshold, it generates a new synthesis condition and re-initiates synthesis.

Abstract: A self-healing conjugated polymer is disclosed. The self-healing conjugated polymer has hydrogen bonding functional groups introduced into its side chains. Due to this structure, the conjugated polymer is imparted with the ability to recover through self-healing while maintaining its inherent properties (for example, physical and electrical properties). Based on this effective self-healing ability, the conjugated polymer is expected to find application as a biomaterial, a pharmaceutical material, a nonlinear optical material or an organic electronic material.
