This book summarizes some recent developments in the area of high-energy high-density (HEDM) materials. Rather than being comprehensive in scope, emphasis is given to structural and bonding features of highly energetic - terials with possible applications as high explosives (secondary explosives) or propellants. In this book we do not focus on primary explosives (e.g. lead azidereplacements)sincebyde?nitiontheexplosiveperformance(detonation velocity and detonation pressure) of such materials - although very sensitive -are much less energetic than secondary (high) explosives. Modern HEDMs derive most of their energy (i) from oxidation of the c- bon backbone, as in traditional energetic materials, (ii) from ring or cage strain, or (iii) from their very high positive heat of formation. Examples of the?rstclassare traditionalexplosives, suchasTNT, RDXand HMX.Modern nitro-compounds, such as CL-20 or the recently reported hepta- and octa- trocubanes, belong to the second group of explosives and possess very high densities and enhance the energies utilizing substantial cage strain. Members of the third class of compounds are high-nitrogen compounds (up to 85% - trogencontent), such as aminotetrazole and nitrotetrazolederivatives, which show the desired remarkable insensitivity to electrostatic discharge, friction and impact, while having very high positive heats of formation and therefore very high explosive powers. The synthesis of energetic, non-nuclear materials for military application has been a long-term goal in various academic and military research groups worldwide. Some of the current challenges that face HEDMscientists are: Demandforenvironmentallycompatibleandtoxicologicallyacceptable- plosives and propellants. Examples are replacements for TNT, RDX and HMXsince nitro-explosivesper se, aswellastheir environmental transf- mation products, are toxic."

Chemistry of High-Energy Materials continues in this new and revised 6th edition to provide fundamental scientifi c insights into primary and secondary explosives, propellants, rocket fuels and pyrotechnics. It expands with new research developments, including new melt casts, reactive structure materials, a computational study on the detonation velocity of mixtures of solid explosives with non-explosive liquids, calculation of craters after explosions. This work is of interest to advanced students in chemistry, materials science and engineering, as well as to all those working in military and defense technology.

For a chemist who is concerned with the synthesis of new energetic compounds, it is essential to be able to assess physical and thermodynamic properties, as well as the sensitivity, of possible new energetic compounds before synthesis is attempted. Various approaches have been developed to predict important aspects of the physical and thermodynamic properties of energetic materials including (but not limited to): crystal density, heat of formation, melting point, enthalpy of fusion and enthalpy of sublimation of an organic energetic compound. Since an organic energetic material consists of metastable molecules capable of undergoing very rapid and highly exothermic reactions, many methods have been developed to estimate the sensitivity of an energetic compound with respect to detonationcausing external stimuli such as heat, friction, impact, shock and electrostatic discharge. This book introduces these methods and demonstrates those methods which can be easily applied.

This book discusses methods for the assessment of energetic compounds through heat of detonation, detonation pressure, velocity and temperature, Gurney energy and power. The authors focus on the detonation pressure and detonation velocity of non-ideal aluminized energetic compounds. This 2nd Edition includes an updated and improved presentation of simple, reliable methods for the design, synthesis and development of novel energetic compounds.

Fur viele Menschen ist die Chemie eine schwer verstandliche Wissenschaft, und die Hemmschwelle, sich mit ihr auseinanderzusetzen, ist entsprechend gross. Insbesondere der Einstieg wird erschwert durch physikalische und mathematische Modelle und Grundlagen, die eher abschrecken als erklaren. Wie gut ware es, ein Buch zu haben, welches auf die detaillierte Beschreibung dieser komplexen Modelle zu Beginn verzichtet und diese erst ins Spiel bringt, wenn sie zum weiteren Verstandnis notwendig werden?

Das vorliegende Buch besticht nicht nur durch den klaren und leicht verstandlichen Schreibstil der Autoren, der auch junge Menschen anspricht, sondern durch einen ganz neuen didaktischen Ansatz. Der Einstieg in die spannende Welt der Chemie erfolgt uber die anorganische Stoffchemie, und die andernorts meist schwer verstandlichen physikalischen und mathematischen Grundlagen werden erst behandelt, wo sie in direktem Zusammenhang zum Thema stehen. So kannder Leser nach und nach in die Materie "hineinwachsen" - Aha-Erlebnisse nicht ausgeschlossen -, ohne gleich zu Beginn abgeschreckt oder gar frustriert zu werden.Dadurch wird dieses Buch der ideale Begleiter fur Studierende der Chemie im Bachelor- und Lehramtsstudiengang, aber auch fur Studierende mit Nebenfach Chemie und fur all diejenigen, die sich gezwungenermassen mit Chemie auseinandersetzen mussen. Lehrer der gymnasialen Oberstufe konnen Anregungen fur ihre Unterrichtsgestaltung gewinnen, und Schulern kann das Werk eine Entscheidungshilfe bei der Suche nach dem richtigen Studienfach sein. Vielleicht ist es ja doch Chemie?"
