Theoretical Basis of the Experimental Tools

Research is seeing what others have seen and thinking what nobody has thought. 

The equations used in our study of the thermodynamics and kinetics of thermal electron reactions using the ECD and NIMS are presented. The ECD and NIMS methods were developed in our laboratories. These are used to determine the rate constants, electron affinities, partition function ratios, and bond dissociation energies of molecules and energies for the formation of complexes of anions. The general kinetic model for the ECD and negative-ion mass spectrometry is presented. Molecules will be classified using example data. 

The electron affinities of many of the molecules determined in the ECD or NIMS have been verified by half-wave reduction potentials and charge transfer complex data. These methods were developed in the 1960s but have been significantly improved. The relationship between the electronegativity and the electron affinities and ionization potentials for aromatic hydrocarbons can be used to support the Ea. The use of the ECD model and these techniques to estimate the electron affinities of aromatic hydrocarbons are illustrated for selected compounds. We will also describe the use of charge transfer complex data to obtain the electron affinities of acceptors.

In this work, we have demonstrated that modern QSPR modeling methods are becoming an important tool for computer-aided designs of new metal binders. Further developments depend not only on new data-mining techniques and descriptors applied, but also on the quality of the experimental data used for the training and validation of the models. Thus, both theoretical and experimental chemists should make an effort to build a basis for predictive structure-property modeling that will accelerate the development of target molecules and materials. 

It is interesting to note that the different contributors to this session covered several aspects of living organisms from innovative viewpoints on the basis of new experimental and theoretical tools for understanding the response of stressed organisms under extreme conditions. 

NMR-SIM can be seen as a software tool to analyse separately the effects on a NMR spectrum of different experimental variables such as spin system, pulse sequence and experimental parameters. The simulation program reduces the number of experimental parameters to a minimum to resemble as closely as possible a real experiment. This reduction in the number of variable parameters is a basic principle of scientific research because often the relationship between only a limited number of parameters can be interpreted unambiguously. The parameter reduction also speeds up calculation time. As illustrated in Fig. 4.1 the NMR spectrometer, represented by the magnet and computer, can be replaced by a computer plus software and the NMR sample by a defined theoretical spin system. Such an "ideal spectrometer" is the basis of the NMR-SIM or NMR experiment simulator software tool. 

The target of the work was to improve the level of detail in the analysis of the experimental resjmnse function. Pitting the theoretical (but not the Electrochemical Equivalent Circuits-based) frequency response function to the experimental data is shown to provimetal-insulator interface. On these basis, changes in surface dif-fusivity values might be effectively used to track the evolution of the interface under T H tests, thereby providing a novel tool to predict adhesion failure. 

MCFCs based on natural gas fuel have been commerciaUzed across the world. In general, natural gas MCFCs are economically inferior to coal power electricity. More economic fuels such as decomposition gas of organic waste and coal gas, and so on, are required for wide scale use of MCFC. To investigate the validity of a new fuel, performance analysis tools should be prepared. The methods in this work can be utilized, but some improvements are also necessary. One is the establishment of a theoretical and experimental basis of the AC impedance method for the performance analysis of MCFCs. The strong point of convenient measurement of the method has been weakened by its obscure analytical basis. Another one is the verification of the relationships among the measurement tools listed in this work. 

This electro-optical effect, commonly observed as transient changes in optical birefringence of a solution following application, removal, or reversal of a biasing electric field E(t), has been used extensively as a probe of dynamics of blopolymer solutions, notably by O Konski, and is a valuable tool because it gives information different in form, but related to, results from conventional dielectric relaxation measurements. The state of the subject to 1975 has been comprehensively presented in two review volumes edited by O Konski (25). The discussion here is confined to an outline of a response theory treatment, to be published in more detail elsewhere, of the quadratic effect. The results are more general than earlier ones obtained from rotational diffusion models and should be a useful basis for further theoretical and experimental developments.
