The organic residue produced in the laboratory from a hydrocarbon plasma was termed a quenched carbonaceous composite (QCC) by the Japanese chemist A. Sakata and his colleagues. They proposed that QCC, a possible component of  interstellar dust, might be the carrier of the 217.5-nm interstellar absorption feature ( UV absorption bump) and the origin of some of the infrared spectral features in the interstellar medium otherwise attributed to  polycyclic aromatic hydrocarbon molecules.
