Sensitivity of Energetic Materials: Prediction and Measurement of Shock, Impact, Friction, and Spark Sensitivity provides an in-depth exploration of the sensitivity of energetic materials, including how compounds such as explosives, propellants, and pyrotechnics respond to various external stimuli (sparks, shocks, impacts, and friction). Starting from foundational principles, the book systematically builds toward advanced experimental techniques and state-of-the-art computational models that predict material sensitivity and behavior. Its primary objectives are to synthesize the latest research, present practical testing methods, and deliver predictive tools that support safer, more innovative work with energetic materials, making it an essential reference for the field. The topic is both significant and timely, given the ongoing development of new energetic compounds, the need for rigorous safety standards, and the growing application of computational and machine learning methods in analytical chemistry and material science. Key themes include the underlying science of sensitivity, experimental protocols, computational and machine learning models, and real-world case studies addressing both established and emerging materials (including nitramines, polynitro arenes, and ionic liquids). The book’s structure encompasses theoretical background, measurement techniques, predictive modeling, and practical applications. Its target audience includes academic researchers, postgraduate students, and industry professionals in chemistry, materials science, engineering, defense, aerospace, mining, and industrial safety.

The combustion properties of organic materials are used to assess their safety specifications. This knowledge is necessary to avoid potentially disastrous fires. The experimental determination of the combustion properties of a new organic compound is laborious and sometimes even impossible. This book describes methods for the determination and prediction of the combustion properties of organic compounds, along with some examples and exercises.

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.

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.

Due to the advances of various methods for the prediction of toxicity of organic compounds and ionic liquids (ILs), it is necessary to review these methods for scientists and students. It is essential to compare the advantages and shortcomings of these methods. Since many organic compounds and ILs are synthesized each year, this book introduces suitable models for the assessment of their toxicities. This book reviews the best predictive methods for the prediction of toxicity of organic compounds and ILs, which were derived by in vitro or in vivo experiments. Different available quantitative structure‐toxicity relationship (QSTR) models based on various descriptors have been discussed to predict toxicity parameters such as LD50 (50% lethal dose), EC50 (the concentration of the desired IL that produces mortality of 50 percent of the bacterial population) and log(IGC50-1) (logarithm of 50% growth inhibitory concentration of T. pyriformis) of various classes of organic compounds and ILs. The reliability of these methods is compared and discussed. Each chapter contains some complimentary problems with their answers, which can improve the experience of students and researchers. The introduced subjects are suitable for advanced students in chemistry, biochemistry, medicinal chemistry, and chemical engineering.

This publication addresses the critical need for chemists engaged in the synthesis of new energetic compounds to comprehensively evaluate physical and thermodynamic properties, as well as sensitivity to various stimuli.
