Carbon soot was generated by laser ablation under oxygen-free and regulated-temperature conditions at 300 K and 1500 K. The soot was significantly oxidised by being exposed to air in darkness. The degree of oxidation was determined to be 0.038±0.012 and 0.093±0.009 for the high temperature (HT) soot and the low temperature (LT) soot, respectively, on the basis of elemental analysis, XPS and Karl-Fischer...
This work deals with the energetics of inter- and intramolecular hydrogen bonds in some phenolic derivatives. It shows that the calorimetric measurement of the enthalpy of sublimation (or vaporization) of these compounds contributes efficiently to determine energy values of this kind of bonds and to understand the crystalline structure of these compounds. Have been estimated, in kJ mol - ...
