The conceptual connection between cluster and solid-state chemistries is the unifying theme of the first seven chapters. Complementary empirical connections between cluster and solid-state chemistries are emphasized in this final chapter. That is, the synthesis of solid-state materials from molecular precursors including clusters permits the strengths of molecular synthesis to be used in the development of new materials. On the other hand, the utilization of Zintl clusters as novel reagents in solution permits the advantages of thermodynamically driven solid-state synthesis to be transferred to the production of clusters in solution. Most of the examples discussed could have been included in earlier chapters, but are gathered here to serve as a review as well as a stimulus to creative thought for future research in cluster and materials chemistries. 

Dielectric polarizabilities are useful for prediction of dielectric constants of new materials and compounds whose dielectric constants have not been measured, and in calculations of energies of the formation and migration of defects. In addition, deviations from the polarizability additivity rule are useful in understanding certain physical properties such as thermodynamic functions and ionic and electronic conductivity." ... 

The thermal stability of compounds is able to be evaluated by discussion based on the thermodynamic data and/or the electronic structures. As for the search of new materials, one can get information on the electronic structure using either the molecular orbital or the band calculations, though the thermodynamic data may not be obtainable in some cases. 

Solid-state electrochemistry is an important and rapidly developing scientific field that integrates many aspects of classical electrochemical science and engineering, materials science, solid-state chemistry and physics, heterogeneous catalysis, and other areas of physical chemistry. This field comprises - but is not limited to - the electrochemistry of solid materials, the thermodynamics and kinetics of electrochemical reactions involving at least one solid phase, and also the transport of ions and electrons in solids and interactions between solid, liquid and/or gaseous phases, whenever these processes are essentially determined by the properties of solids and are relevant to the electrochemical reactions. The range of applications includes many types of batteries and fuel cells, a variety of sensors and analytical appliances, electrochemical pumps and compressors, ceramic membranes with ionic or mixed ionic-electronic conductivity, solid-state electrolyzers and electrocatalytic reactors, the synthesis of new materials with improved properties and corrosion protection, supercapacitors, and electrochromic and memory devices. 

The method of MD, with variations and extensions, is one of the principal tools in the computer simulation of polymers. In contrast to any form of MC method, in which some elements of a statistical nature are introduced, MD is deterministic and gives a direct way to study both equilibrium properties and time evolution. It calculates the time-dependent behavior of a model system and provides detailed information on the fluctuations, conformational changes, and thermodynamics of synthetic polymers, proteins, and nucleic acids. It may be used as an aid for analysis of experimental data, and more ambitiously as design tools in the development of new materials. 

Ordered mesoporous materials are of significant industrial interest, especially in fields of catalysis, novel adsorbents, nanoparticles/nanocomposites, and sensor applications. Hence, it becomes necessary to understand the various fundamental thermodynamic aspects related to the mesoporous material, which in turn will facilitate better design of new material for intended industrial application. 

Accurate prediction of materials properties and their optimization with respect to composition and structure prior to s)mthesis is a key challenge in computational materials science. Some of the main challenges for the design of new materials based on atomic scale computer simulations are the prediction of crystal structures and thermodynamic stabilities [1], and the assessment of properties at larger length and time scales than those accessible to atomic scale modeling approaches [2].
