We used molecular dynamics simulations to determine the sucrose hydrogen bond network (HBN) in amorphous sucrose with 0–50% w/w water. We find that the onset of a percolated sugar HBN network (between 33% and 40%) coincides with the experimental observation of the decoupling of viscosity and probe diffusion for these mixtures. The analysis of the free volume (FV) in these mixtures shows a non-m...

The additives present in polyvinyl chloride (PVC) materials are the major source of organic by-products during PVC degradation. thermal stabilizer and plasticizer main that endow with required properties its processing. However, these two easily migrate when samples obtained by physical mixing PVC. This causes reduction sample efficacy increase formation radiolysis process. In this work, kinds ...
