LIG 3 (IMAGE) Rice University Caption Rice University graduate student Duy Xuan Luong suspends a three-dimensional block of laser-induced graphene atop two willows. The lab uses an industrial laser to transform inexpensive polyimide plastic into graphene foam at room temperature, and then binds the sheets to produce lightweight, conductive 3-D graphene.
