■ Hong Byung-hee/ Professor of Chemistry at Seoul National University The 55th protagonist! Dr. Hong Byung-hee! The graphite used in pencil leads is a structure in which honeycomb-shaped hexagonal 'graphene' is stacked in layers. Graphene has been called a dream new material because it theoretically has more perfect characteristics than any other material that has appeared so far, and it was first realized by a Russian scientist in 2004, and it was thought that commercialization was just around the corner. However, the graphene realized from graphite was too small to be commercialized. To overcome this limitation, Dr. Hong Byung-hee created graphene in a new way through chemical methods. As a result, graphene could be produced in large quantities, and the production efficiency increased by about 40 times compared to before. Since this technology he developed was the first of its kind, he obtained numerous patents not only in Korea but also overseas. Dr. Hong Byung-hee started application research in a new field by utilizing the characteristics of graphene, which is made up of only carbon. Dr. Hong Byung-hee believes that graphene will create a platform to create another industry, just as one industry was created with a material called silicon. Dreaming alone won't make it happen, but let's take a look at his story of realizing his dream through endless challenges. A look into the research and lives of scientists leading science in Korea and cheering them on (Bravo K-SCIENTIST) #Graphene #NewMaterials #NewRenewableEnergy #KAIST #TechnologyDevelopment #NewTechnology #NobelScientist #Paper #NaturePaper #AppliedChemistry #LGChemicals [YTN Science Original Article] https://science.ytn.co.kr/program/pro...
