Comments on Contemporary Methods of Oxygen and Nitrogen Free Radical Detection... 

Due to plasma treatment the radicals (R, free spin) are generated on polymer chain. Not only C-H but also C-C bonds are likely to brake, the later leading to fragmentation of polymer chain. The radical concentration determined by EPR method is in Table 3. The concentration of free radicals R decreases during the aging to about quarter of the initial after 80 days. The decrease of R is a result of radical recombination [h]. Detailed comment of EPR observation ( aging of radicals) is described too [79]. 

Comment. In this example we see that two distinct zones are present. Situations may be encountered where even another zone may be present. For example, if the entering liquid contains insufficient reactant, a point is reached in the tower where all this reactant is consumed. Below this point physical absorption alone takes place in reactant-free liquid. The methods of these examples, when used together, deal in a straightforward manner with this three-zone situation and van Krevelens and Hoftijzer (1948) discuss actual situations where these three distinct zones are present.

Molecular simulations are used most often for modeling proteins and nucleic acids. We mention the methods here only because they are methods for computing a free energy directly. However, they are rather complex calculations, so we will keep our comments brief. Molecular dynamics simulations give information about the variation in structure and energy of a molecule over an interval of time (78,79). In MD, each atom moves according to Newton s equations of motion for classical particles ... 

Comments This method could obviously be applied to other than just metallic powders but the necessary pre-requisite is that the powder is free-flowing so that it will flow through the specified 2.5 mm or 5 mm orifice. The density measured is the bulk density of the material as poured under the specified conditions, and this will probably be lower than other bulk densities like the tap density.
