Chemical features domains

Whereas natural monomers like terpenes and sugars constitute building blocks for a limited number of macromolecular structures, associated with their own peculiar chemical features, the realm of furan polymers bears a qualitatively different connotation in that it resembles the context of petrol refinery, that is, it is open to a whole domain of monomers, whose only specificity is the fact that they all incorporate the furan heterocycle in their structure. This state of affairs stems from the fact that, as in petroleum chemistry, saccharide-based renewable resources are used to produce two first-generation furan derivatives, which constitute the substrates capable of being converted into a vast array of monomers and hence a correspondingly large number of macromolecular structures associated with materials possessing different properties and applications [34].

Chemical descriptors are used widely in chemoinformatics research to map the chemical features of compounds into the domain of numerical and statistical analysis.Once molecular features are expressed numerically, or as enumerated factor sets (e.g., structural keys), the tools for numerical and statistical analysis can then be applied to analyze and compare molecular similarity or diversity of compound collections. 

To solve the problems of representation and control, we will employ the framework of the branch-and-bound algorithm, which has been used to solve many types of combinatorial optimization problems, in chemical engineering, other domains of engineering, and a broad range of management problems. Specifically, we will use the framework proposed by Ibaraki (1978), which is characterized by the following features ... 

This book is the first attempt to provide a detailed description of scientific basis of the method of semiconductor chemical sensors which are presently widely applied in various domains of industry and in everyday life. The major feature of this book (which distinguishes it from the literature published up to date) is that it mainly examines the use of the method of semiconductor sensors in fine physical and chemical studies. 

Dynamic parameters for heterogeneous systems have been explored in the liquid, liquid like, solid like, and solid states, based on analyses of the longitudinal or transverse relaxation times, chemical exchange based on line-shape analysis and separated local field (SLF), time domain 1H NMR, etc., as summarized in Figure 3. It is therefore possible to utilize these most appropriate dynamic parameters, to explore the dynamic features of our concern, depending upon the systems we study. 

The aim of this chapter is to discuss chemical reactivity and its application in the real world. Chemical reactivity is an established methodology within the realm of density functional theory (DFT). It is an activity index to propose intra- and intermolecular reactivities in materials using DFT within the domain of hard soft acid base (HS AB) principle. This chapter will address the key features of reactivity index, the definition, a short background followed by the aspects, which were developed within the reactivity domain. Finally, some examples mainly to design new materials related to key industrial issues using chemical reactivity index will be described. I wish to show that a simple theory can be state of the art to design new futuristic materials of interest to satisfy industrial needs. 

With regard to the chemical domain, the attitudes of chemical engineers were not as unambiguously favorable as might be expected at first (1 5). This is not to say that indifference or even hostility to chemistry were dominant features of chemical engineering, but the existence of these currents of...
