But he says that, after some time, they realized that many plastic polymers also contain atomic hydrogen. “If we end up with graphene, which is 100% pure carbon, where is all the atomic hydrogen locked in the plastic going?” he asked. They therefore set about trapping and studying the...
(Fig.5a) and the other in which we increase the light-matter coupling (Fig.5c). In the black traces of Fig.5d–f and Fig.5g–i, we plot the simulated population dynamics of the LP and the (6,5)/(7,5) CNTs, respectively. We also show the integrated population of the (7,5) ...
