Article Synopsis
- A molecular dynamics simulation was used to create a structural model of ED-20 epoxy resin cured with triethylenetetramine, focusing on its hardening process.
- The model incorporated cross-links between amino groups and epoxide carbon atoms, successfully replicating the experimentally observed glass transition temperature of 360-364 K.
- The study analyzed how changes in the macromolecular structure, glass transition temperature, and cross-linking affect the epoxy resin's physical properties, particularly during the transition from a glassy to a viscoelastic state with increasing temperature.
Crocus sativus (Iridaceae) or saffron is important for its flavoring properties in the food industry and its medicinal properties in the pharmaceutical industry. Real saffron must meet the quality requirements set to FDA or ISO specifications, and in addition, must be safe and non-toxic. An "autumn crocus" or scientific name Colchicum spp.

The systematic search for prevalent conformational state of the cation was carried out by computer simulations in combination with one- and two-dimensional NMR experiments. For that purpose, we proposed a novel algorithm for the generation and selection of conformers based on molecular dynamics and clustering in the space of principal components.
