In the following sections, our first-principles bottom-up methodology will be described from a physical perspective (a full description on mathematical terms can be found in Ref. [7]). Then, the use of this methodology will be illustrated on the a-2-hydro nitronyl nitroxide [8] (hereafter called a-HNN), the simplest member of the nitronyl nitroxide family (R = H in Figure 1). The macroscopic magnetic properties and crystal structure of this compound are well known (its crystal structure is stored in the Cambridge Crystallographic Database [9] with refcode name TOLKEK).

A correlation [93] relating crystal entropy to metallic radius, atomic wei t, magnetic properties, and electronic structure has permitted the accurate calculation of unknown entropies for these elements. This approach does require a defined electronic structure in order to predict accurate entropy values. Thermodynamics for the transplutonium metals have been sumnmrized [94,95]. 

The crystal structures of the borides of the rare earth metals (M g) are describedand phase equilibria in ternary and higher order systems containing rare earths and B, including information on structures, magnetic and electrical properties as well as low-T phase equilibria, are available. Phase equilibria and crystal structure in binary and ternary systems containing an actinide metal and B are...

The second attractive feature of bimetallic nanoparticles is their magnetic property. In addition to the fact that the size control of bimetallic nanoparticles composed of noble and 3d-transition metals is easier than that of 3d-transition monometallic nanoparticles, recent technology makes it possible to control the compositions and crystal structures of such bimetallic nanoparticles. Some examples are provided in Section 11.3.2. 

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.
