Figure 21.5 Strategies for understanding nanomaterial enviromnental health and safely, toxicity and biological response include nanomaterial classihcalion, that is, compositional classification (metal, metal oxide, polymer, senticonductor, carbon-based, etc.) for a material that has one dimension between 1 and 100 mn chentical composition in terms of bulk and surface size considerations, primary and secondary (aggregate) sizes and geometric structure which includes shape and porosity.

In addition to the specific textural class of individual particles, the range of particle sizes common in naturally-occurring lake sediments necessitates use of an additional sediment mixture classification system to actually name the material. Several such systems are in common use (Fig. 2), and, as with sediment compositional classification systems, there is little uniformity of practice or nomenclature. 

Compositional classification avoids the difficulty of linking components to sources. As a compositional component, the Fe-Mn oxyhydroxide fraction is unambiguous even if its origin is uncertain (mixed allogenic, authigenic, and diagenetic), and we cannot, in practice, measure it with certainty. Nevertheless, this classification scheme is the one to keep most clearly in mind, as it can be used to infer origin, and can be deduced from data analysis and/or sequential extraction. 

Operational classification (by extraction agent, or procedure) has the advantage of being unambiguous (though not necessarily repeatable unless very strict conditions are adhered to). However, numerous schemes exist leading to problems with comparability. There is also the problem of what to call the fractions, and how the fraction labels link with the genetic and composition classifications. The fractions are operationally defined and should...

Abstract This chapter describes vegetable oil-based polymer nanocomposites. It deals with the importance, comparison with conventional composites, classification, materials and methods, characterisation, properties and applications of vegetable oil-based polymer nanocomposites. The chapter also includes a short review of polymer nanocomposites of polyester, polyurethanes and epoxies based on different vegetable oils and nanomaterials. The chapter shows that the formation of suitable vegetable oil-based polymer nanocomposite can be considered to be a means of enhancing many of the desirable properties of such polymers or of obtaining materials with an intrinsically new set of properties which will extend their utility in a variety of advanced applications. Vegetable oil-based shape memory hyperbranched polyurethane nanocomposites can be sited as an exampie of such advanced products. 

Chemical Composition. The composition classification describes synthetic adhesives as thermosetting, thermoplastic, elastomeric, or combinations of these. They are described generally in Table 7.9.

Chapters 6 and 7 are dedicated to the table s chemical content, especially the conceptual framework employed in its construction. Chapter 6 will deal with the classification s most general principle, the principle of classification according to composition. Classification according to composition is not a universal mode of chemical classification, but a historical one. Based on our principal discussion of the modem concept of chemical composition in part I, three of the historical preconditions of this classification will be studied in this chapter 1) the kind of chemical substances presupposed by this classificatory principle that is, pure chemical substances which became the subject of chemical practice in the early modem period 2) the demarcation of the modem notion of composition from earlier concepts of the constitution of substances and 3) the development of the analytical method of procuring certain knowledge of chemical composition.
