The Atlanta Business Journal lists another example of businesses wanting to get closer to Georgia Tech's research. Graphenano, a Spanish company hoping to make a lot of graphene – a thin yet ultra-strong carbon-based substance that could lead to better batteries and composite materials – may move its North American headquarters to Atlanta. Georgia Tech is a leader in graphene research, and the story cites a May study on a potentially more efficient way to make graphene from School of Physics Professor Uzi Landman and Bokwon Yoon, a research scientist with the school. Both are with the Center for Computational Materials Science; Landman is its director.
