Oil shale is an important potential energy source, consisting of an inorganic mineral matrix containing organic matter. The organic matter is generally divided into two fractions: bitumen and kerogen. Kerogen is insoluble in normal organic solvents
Mechanism of Natural Lacquer Film-Making Processes by Pyrolysis Gas-Chromatography/Mass Spectra，万云洋，Miyakoshi Tetsuo，Natural lacquer is a complex mixture and the film-making processes are rather complicated. Many mechanisms of it existed but contradi
Light-emitting silicon nanocrystals are prepared by the pyrolysis of silane and subsequent controlled size-reduction by chemical etching. These nanocrystals show luminescence tunable through the full visible spectral region. The luminescence rate inc
The pyrolysis of coal of different ranks has been examined by chromatographic technique. The results obtained reveal that the ratio of C2H4/CH4 in gaseous products is linearly related to the content of volatile fraction of coal. This fact suggests th
