Description of method and materials

In this chapter, the fundamentals and the most common methods and techniques for the synthesis, processing, characterization, and modification of mac-romolecular materials are described briefly, as an introduction to the special Chaps. 3,4, and 5. The main emphasis is on the description of methods and techniques used in laboratories, but some examples from industrial practice are also mentioned. 

Methods submitted include single- and multi-analyte methods for parent compounds and for degradates of concern. Pesticide regulatory methods are needed for each type of environmental matrix fate methods may be designed for soil, water, plant tissue, animal tissue or air, but are predominantly for soil and water. Analytical methods need to include a complete description of the procedure, materials and equipment in order to be completely reproducible. The methods should be practical and rapid and, to the extent possible while maintaining other quality objectives, inexpensive (often State and local regulatory agencies with few available resources need to utilize them). 

Detailed description of all mentioned material processing tools can be found in special literature and handbooks2 [7-11]. In this chapter, only the most popular method of composite production the method of a material sputtering on a substrate [4,27] - will be discussed. 

Size-dependent structure and properties of Earth materials impact the geological processes they participate in. This topic has not been fully explored to date. Chapters in this volume contain descriptions of the inorganic and biological processes by which nanoparticles form, information about the distribution of nanoparticles in the atmosphere, aqueous environments, and soils, discussion of the impact of size on nanoparticle structure, thermodynamics, and reaction kinetics, consideration of the nature of the smallest nanoparticles and molecular clusters, pathways for crystal growth and colloid formation, analysis of the size-dependence of phase stability and magnetic properties, and descriptions of methods for the study of nanoparticles. These questions are explored through both theoretical and experimental approaches. 

A comprehensive description of the trial after its completion including a description of experimental methods (including statistical methods) and materials, a presentation and evaluation of the results, statistical analysis and a critical, ethical, statistical and clinical appraisal. 

SPECIFICATION A document or documents giving a description of a starting material, packaging material, intermediate, bulk or finished product in terms of its chemical, physical and (possibly) biological properties together with methods of test A specification normally includes descriptive clauses and numerical clauses, the latter starting standards and permitted tolerances. 

Developing a complete description of the methods and materials used to dean and maintain equipment, and when necessary, instructions for disassembling and reassembling each artide of equipment to ensure proper deaning and maintenance ...
