    About the Course. This 3-day class introduces basic principles, techniques, and equipment for the most commonly-used physical and analytical tests on polymeric materials, including: mechanical properties, chemical analysis, combustibility, instrumental analysis, electrical properties, and thermal aging.   1. Introduction. Chemically reactive molecules containing oxygen are termed reactive oxygen species (ROS). Reactivity may be due to the presence of unpaired electrons, but there are also reactive nonradical species such as hydrogen peroxide (H 2 O 2).Examples of ROS are shown in Figure 1 and include peroxides and free oxygen ions generated during the normal metabolism of oxygen via Cited by:
