Originating as a theoretical prediction in the 1940s, with experimental isolation from graphite in 2004 ... and positioning of the Raman bands in the graphene spectrum. This article demonstrates ...

Our instrument is especially optimized for fast hyperspectral imaging of complex samples and materials, where a full Raman spectrum is collected at every pixel. This technique, combined with advanced ...

"Evidence suggests these 'diamonds' formed by shock compression of the initial graphite," the team wrote in their paper. "It was noted from Raman spectroscopy that a few areas within some grains ...
