Solid State Astrochemistry

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.

Solid State Chemistry

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.

Chemistry

Structure and Dynamics

The Spencer text is the only text that is built on independently researched pedagogy on the best way to teach General Chemistry. Chemistry: Structure and Dynamics, 5th Edition emphasizes deep understanding rather than comprehensive coverage along with a focus on the development of inquiry and reasoning skills. While most mainstream General Chemistry texts offer a breadth of content coverage, the Spencer author team, in contrast, focuses on depth and reader preparation for future studies. The fifth edition is revised in keeping with our commitment to the chemical education community and specifically the POGIL (Process Oriented Guided Inquiry Learning) Project. This text reflects two core principles, first that the concepts that are covered are fundamental building blocks for understanding chemistry and second, that the concepts should be perceived by the readers as being directly applicable to their interests and careers. The authors further provide this "core" coverage using 1 of 3 models; data-driven, chemical theories and reader understanding, which allows for a more concrete foundation on which readers build conceptual understanding.

The Effects of Implementing the Cooperative Learning Structure, Numbered Heads Together, in Chemistry Classes at a Rural, Low Performing High School

Introductory Chemistry: An Active Learning Approach

Teach the course your way with INTRODUCTORY CHEMISTRY. Available in three flexible formats (a standard paperbound edition, a loose-leaf edition, and a hybrid edition). This text allows you to tailor the order of chapters to accommodate your particular needs, not only by presenting topics so they never assume prior knowledge but also by including any and all necessary preview or review information needed to learn that topic. The authors' question-and-answer presentation allows students to actively learn chemistry while studying an assignment. This approach is reflected in three words of advice and encouragement that are repeated throughout the book: Learn It Now! This edition integrates new features such as outstanding technological resources, coached problems in a two-column format, and enhanced art and photography, all of which dovetail with the authors' active learning approach. Even more flexibility is provided in the new edition by the Cengage YouBook, an electronic version of the text that features interactivity, integrated media, and additional algebra coverage. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.
