Description Graphene oxide (GO) is an organic macromolecule that is only a couple of atoms thick but thousands of atoms wide (like a molecular-scale bed sheet). Koltonow and his colleagues are able to assemble these atomically-thin sheets into a solid, conductive foam with a high surface area. The foam can be used to create electrodes for batteries and supercapacitors, making such energy storage devices smaller and lighter. In this image, GO sheets (purple-orange) cast shadows from light that is scattered off the foam (green-yellow), creating an eerie effect.
These images stem from cutting-edge research on campus, winning our annual Scientific Images Contest which goes on display in galleries across Chicago.
Through partnerships with schools and community groups, we train Northwestern researchers to share their expertise and creativity in a community centered way. Sales from these images goes to support our education and outreach activities, connecting researchers to the wider community.
