The fundamentals of astrochemistry in the gas phase are relatively well established, in contrast to the special relevance attributed to processes involving interstellar dust grains - the solid component of matter diffused among the stars. This book presents the state of the art in relation to the ways grains interact with gases, the catalytic role played by dust that allows key molecular species (H2 as well as many complex, possibly prebiotic species) to be formed on its surface - which cannot be obtained efficiently by any other mechanisms, and the interaction between solids (dust grains, icy mantles, cometary nuclei, satellites of the giant planets and minor bodies in the Solar system) in space and energetic agents such as UV photons and fast particles. The presence and importance of PAH, which may represent the smallest component of the grains, is considered in relation to possible astrobiological pathways and the ever-present mystery of the ubiquitous presence of Diffuse Interstellar Bands and their carriers.
Synthesis, Structure, and Properties of Selected Oxides and Sulfides
The subject matterofsolid state chemistry lies within the spheres ofboth physical and inorganic chemistry. In addition, there is a large overlap with solid state physics and materials engineering. However, solid state chemistry has still to be recognized by the general body ofchemists as a legitimate subfield ofchemistry. The discipline is not even well defined as to content and has many facets that make writing a textbook a formidable task. The early studies carried out in the United States by Roland Ward and his co workers emphasized the synthesisofnew materials and the determination oftheir structure. His work on doped alkaline earth sulfides formed the basis for the development of infrared phosphors and his pioneering studies on oxides were important in understanding the structural features of both the perovskite oxides as well as the magnetoplumbites. In 1945, A. F. Wells published the first edition of Structural Inorganic Chemistry. This work attempts to demonstrate that the synthesis, structure, and properties of solids form an important part of inorganic chemistry. Now, after almost 50 years during which many notable advances have been made in solid state chemistry, it is still evident that the synthesis, structure determination, and properties of solids receive little attention in most treatments of inorganic chemistry. The development of the field since the early studies of Roland Ward (early 1940s) has been rapid.

"Solid-State Theory - An Introduction" is a textbook for graduate students of physics and material sciences. Whilst covering the traditional topics of older textbooks, it also takes up new developments in theoretical concepts and materials that are connected with such breakthroughs as the quantum-Hall effects, the high-Tc superconductors, and the low-dimensional systems realized in solids. Thus besides providing the fundamental concepts to describe the physics of the electrons and ions comprising the solid, including their interactions, the book casts a bridge to the experimental facts and gives the reader an excellent insight into current research fields. A compilation of problems makes the book especially valuable to both students and teachers.
The advent of quantum mechanics in the early twentieth century has
fundamentally improved our understanding of the physics of matter in general
and of the solid state in particular. Consisting of a very large number of atoms,

Solid state physics is the branch of physics that is primarily devoted to the study of matter in its solid phase, especially at the atomic level. This prestigious serial presents timely and state-of-the-art reviews pertaining to all aspects of solid state physics. - Continuation of prestigious serial - Covers cutting edge research and topics in solid state physics
mechanical state, taken to be a deformed state, the amount of deformation is
measured with respect to the reference state. The choice of the reference state is
in general arbitrary and for many problems it is convenient to take it as the ...
