چکیده
Neste manuscrito, o desempenho de alguns aceleradores do tipo sulfenamidas foi avaliado quanto à vulcanização elastômeros. Dados teóricos, gerados através da modelagem moléculas das espécies químicas e suas reações no processo, foram confrontados com dados experimentais referentes a cura borracha natural copolímero estireno-butadieno. A complexidade envolvidas na vulcanização, assim como elastômero escolha composição são fatores que, aliados basicidade efeito estérico moléculas, dificultam uma correlação ideal entre previsibilidade comportamento verificado prática. No entanto, cálculo parâmetros moleculares princípio HSAB mostram-se úteis para aproximar qualitativamente teoria experimental.

متن کاملComputer Aided Molecular Modeling Of Membrane Metalloprotease
Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

Molecular Modeling
About 10,000 years ago, humans began to domesticate plants and animals. Now, it is time for us to domesticate molecules. In today’s polymer materials science, many scientists have synthesized a large number of synthetic polymers, which have been widely used in people’s lives. In a sense, natural polymers, like natural rubber, cellulose, etc., are of less importance than ever before. It is well ...
