Characterization strategies behavioral

For the purpose of this article, fire tests are associated with the second strategy and defined as experimental methods to characterize the behavior of polymers under more severe thermal exposure conditions that are representative of the growth phase of a compartment fire. These conditions are simulated with a gas-fired or electrical heater or a large gas burner turbulent diffusion flame (flame length of the order of a meter or several feet). The incident heat flux to the specimen is primarily radiative when heaters are used, and mainly convective for flame exposure. Total incident heat flux varies from approximately 1 kW/m to more than 100 kW/m. Note that the maximum radiant heat flux from the sim on earth is approximately 1 kW/m. Polymers that are not treated with fire retardant chemicals typically ignite when exposed to heat fluxes of 10-20 kW/m in the presence of a small pilot flame or hot spark. 

The typical strategy employed in studying the behavior of nonlinear dissipative dynamical systems consists of first identifying all of the periodic solutions of the system, followed by a detailed characterization of the chaotic motion on the attractors.

Successfully developing a surface engineering strategy based on surfactant behavior at interfaces requires surface characterization techniques that can validate and quantify surface chemistry changes. This review describes the role of two surface chemistry analysis techniques that have proven highly successful in surfactant analysis x-ray photoelectron spectroscopy (XPS) and static secondary ion mass spectrometry (SSIMS). In Section II, the methods by which these techniques analyze surface chemistry are described. In Section III, recent examples of their application in surfactant-based surface engineering are described.
