image: Compressed glassy carbon contains graphene?like, sp2 carbon atoms (black spheres) connected by diamond?like, sp3 carbon atoms (red spheres). The background shows a high?resolution transmission electron microscopy image with locally ordered, interconnected regions on the nanometer scale. This material relates to a paper that appeared in the June 09, 2017, issue of Science Advances, published by AAAS. The paper, by M. Hu at Yanshan University in Qinhuangdao, China, and colleagues was titled, "Compressed glassy carbon: An ultrastrong and elastic interpenetrating graphene network." view more
