Laser ablation Fourier transform ion cyclotron resonance mass spectrometry, FTIR and solid state 13 C NMR have been used to study bitumen-free raw Kukersite, Torbanite and Goynuk Oil Shale in an attempt to observe whether these materials might be used as fullerene precursors. Solid state 13 C NMR and FTIR spectra and elemental analyses indicated that, upon pyrolysis at 400°C...
Non-hydrolysable macromolecules were isolated from the marine green microalga Chlorella marina where they represent ca. 5% by weight of the dry biomass. Such resistant biomacromolecules, termed algaenans, were previously identified in numerous microalgae (mostly comprising freshwater species) and they were shown to play a major role in the formation of a number of source rocks and oil shales via...
