Determination of Carbon Nanotube Modification by TG-MS and Pyrolysis-GC/MS
… were thermogravi me try-mass spectrometry (TG-MS) and pyrolysis-gas chromatography/mass spectrometry (GC/MS). Samples were heated while the gasses evolved were monitored to determine their identities. The soluble SWNTs were less stable than the non-soluble SWNTS. In addition, they also had much …

Organisch-geochemische Untersuchungen der Oberflächengewässer aus dem Einzugsgebiet der Sielacht Esens (Ostfriesland)
… from the catchment area of the Sielacht Esens. Pyrolysis-GC/MS with TMAH (tetramethylammonium hydroxide) was used to characterize the DOM fractions on a molecular level. The obtained results are compared with the oxidative degradation by cupric oxide (CuO). Ratios of lignin-derived compounds are …

Evaluation of management practices and remediation techniques for improving water quality in agricultural systems
… and TSS (R2 = 0.42-0.87, P < 0.001). The pyrolysis-GC/MS analysis of the runoff sediments indicated higher intensity of lignin-derived compounds in the BR treatment than in the RR and SR treatments. Polysaccharide-derived compounds, dominated by levoglucosan, tended to decrease over the …

Co-Pyrolysis and Co-Combustion of Coal and Biomass
… fuels. Laboratory scale data on synergies in co-pyrolysis is conflicting. Characterisation of co-pyrolysis products from coal and biomass pyrolysis has received limited attention and the data is conflicting. Therefore this thesis seeks to understand possible interactions occurring during …
