Summary The chemical structure of lignin in normal and compression wood of spruce has been studied. Thioacidolysis using both methanethiol and ethanethiol as nucleophiles was used for degradation. The results showed that these nucleophiles work equal

Summary Bauer-McNett fractions of an aspen chemi-thermomechanical pulp showed a significant variation with respect to lignin content and sugar composition, and two of the fractions were found to be particularly rich in middle lamella and secondary wa

Summary Thioacidolysis, periodate oxidation and size exclusion chromatography (SEC) were used for the analysis of spruce lignin samples. The standard thioacidolysis method was modified by including a pre-swelling of the lignocellulosic sample before

The main objective of this project is to study the difference between aged and un-aged post-blast residues and non-blasted explosives. Sand from the post-blast scenes was subjected to accelerated aging (temperature, light and addition of water) over
