Substance abuse and its social consequences are a major public concern for communities throughout the world. The motivations and consequences are deeply imbedded within the social and political structures of all countries, whether they be well-established democracies or developing nations.Every culture shapes the meaning of and responses to substances such as marijuana and heroin over time and across locations, but the broader drug issue has become universal. As the sphere of the problem expands, the experiences and solutions of each nation become more relevant to other countries. International concern over substance abuse has intensified as a result of the rise in production, use, and trafficking of illicit drugs all over the world. Therefore, the practical knowledge of policy development and abuse prevention and treatment strategies in the Middle East have increasing relevance for the rest of the world.

High-Entropy Alloys: Design, Manufacturing, and Emerging Applications presents cutting-edge advances in the field of these materials, covering their mechanics, methods of manufacturing, and applications, all while emphasizing the link between their structure/microstructure and functional properties.The book starts with a section on the fundamentals of high-entropy alloys (HEAs), with chapters discussing their thermodynamics, subgroups (transition metal; refractory; ceramics; metallic glasses and more), physical metallurgy, and microstructural characterization. The next section features chapters which look at manufacturing processes of HEAs, such as liquid metallurgy synthesis, in-situ synthesis, additive manufacturing, machine learning, friction stir welding, and fabrication of coatings for HEAs. The final section of the book covers applications of these materials, including their use as irradiation-resistant structural materials, catalyst materials, electrode materials, HEAs for solid hydrogen storage, and more. The book is a key resource for academic researchers, grad students, and industry professionals working with HEAs across a range of disciplines and applications including aerospace, functional materials, catalyst materials, gas storage, sensing, super-conducting materials, biomedical, civil engineering, energy storage, and energy materials.- Covers the mechanics, manufacturing, and applications of functionally-oriented high-entropy alloys (HEAs)- Discusses the metallurgical composition of HEAs, their microstructural characterization, thermal stability, and how to manufacture them via powder metallurgy, additive manufacturing, and friction stir welding- Reviews applications of HEAs such as for irradiation-resistant structural materials, in biomedical settings, as catalyst materials, for solid hydrogen storage, and more

Mechanics, Additive Manufacturing, and Applications of High-Entropy Alloys provides key insight into the mechanics, additive manufacturing, and application of high entropy alloys (HEAs). The book starts with chapters covering the dynamic mechanical and impact properties of these materials, theoretical models for strengthening HEAs and understanding various modes of failure, their low- and high-velocity impact behaviors, the design of lightweight HEAs, and much more. The book also features chapters outlining additive manufacturing techniques of HEAs, the effect of microstructures on their mechanical properties, and deformation mechanisms. The book concludes with chapters discussing the applications of HEAs, such as in lattice structures, high-energy absorption, nuclear energy, aerospace materials, as well as their recycling and sustainability.Emphasizes the relationship between the structure/microstructure of high entropy alloys (HEAs) and their dynamic mechanical propertiesOutlines techniques for adjusting the composition of HEAs based on certain applicationsCovers the additive manufacturing of HEAsProvides theoretical models for the dynamic-mechanical behaviors of HEAs
