The development of advanced materials with preselected properties is one of the main goals of materials research. Of especial interest are electronics, high-temperature and supemard materials for various applications, as well as alloys with improved wear, corrosion and mechanical resistance properties. The technical challenge connected with the production of these materials is not only associated with the development of new specialised preparation techniques but also with quality control. The energetic charged particle, electron and photon beams offer the possibility of modifying the properties of the near-surface regions of materials without seriously affecting their bulk, and provide unique analytical tools for testing their qUality. This volume includes most of the lectures and contributions delivered at the NATO-funded Advanced Study Institute "Application of Particle and Laser Beams in Materials Technology", which was held in Kallithea, Chalkidiki, in Northern Greece, from the 8th to the 21st of May, 1994 and attended by 73 participants from 21 countries. The aim of this ASI was to provide to the participants an overview of this rapidly expanding field. Fundamental aspects concerning the interactions and collisions on atomic, nuclear and solid state scale were presented in a didactic way, along with the application of a variety of techniques for the solution of problems ranging from the development of electronics materials to corrosion research and from archaeometry to environmental protection.
This book presents a system view of the digital scientific and technological revolution, including its genesis and prerequisites, current trends, as well as current and potential issues and future prospects. It gathers selected research papers presented at the 12th International Scientific and Practical Conference, organized by the Institute of Scientific Communications. The conference “Artificial Intelligence: Anthropogenic Nature vs. Social Origin” took place on December 5–7, 2019 in Krasnoyarsk, Russia. The book is intended for academic researchers and independent experts studying the social and human aspects of the Fourth Industrial Revolution and the associated transition to the digital economy and Industry 4.0, as well as the creators of the legal framework for this process and its participants – entrepreneurs, managers, employees and consumers. It covers a variety of topics, including “intelligent” technologies and artificial intelligence, the digital economy, the social environment of the Fourth Industrial Revolution and its consequences for humans, the regulatory framework of the Fourth Industrial Revolution, and the “green” consequences, prospects and financing of the Fourth Industrial Revolution.
Nanocomposite Structures and Dispersions summarizes the fundamentals and mechanistic approaches in preparation and characterization of colloidal nanoparticles and dispersions, providing the readers a systematic and coherent picture of the field. The book serves as an introduction to the interesting field of nanoscience based on polymer and metal colloidal nanoparticles, and also presents the basic knowledge of polymer colloids preparation. It places a special emphasis on polymer, inorganic and metal nanomaterials classified as nanoparticles, nanocrystals, nanorods, nanotubes, nanobelts, etc. deals with the chemistry of the reaction approaches by which polymer and metal particles are synthesized. The book explores both organic (synthetic and natural) and inorganic materials, as well as their hybrids. It describes in detail terms, definitions, theories, experiments, and techniques dealing with synthesis of polymer and metal particles. It also discusses a variety of synthetic approaches including emulsion, miniemulsion and microemulsion approaches, homogeneous and heterogeneous nucleation approaches under mild and high temperatures. There is also a chapter on modification and passivation of colloidal particles. This book would be of interest to chemical engineers, polymer chemists, organic chemists, colloid chemists, materials scientists and nanotechnologists. Although the text discusses nanoscience and nanotechnology from the viewpoint of a chemist, it would also appeal to those just entering the field and experts seeking information in other sub-fields. - Serves as a general introduction for those just entering the field and experts seeking information in other sub-fields - Variety of synthetic approaches is described including emulsion, miniemulsion and microemulsion approaches, hogeneous and heterogeneous nucleation approaches under mild and high temperatures - Focused on both the organic (synthetic and natural) and inorganic materials, and their hybrids

Selective Laser Sintering Additive Manufacturing Technology is a unique and comprehensive guide to this emerging technology. It covers in detail the equipment, software algorithms and control systems, material preparations and process technology, precision control, simulation analysis, and provides examples of applications of selective laser sintering (SLS). SLS technology is one of the most promising advances in 3D printing due to the high complexity of parts it can form, short manufacturing cycle, low cost, and wide range of materials it is compatible with. Typical examples of SLS technology include SLS manufacturing casting molds, sand molds (core), injection molds with conformal cooling channels, and rapid prototyping of ceramic and plastic functional parts. It is already widely used in aviation, aerospace, medical treatment, machinery, and numerous other industries. Drawing on world-leading research, the authors provide state of the art descriptions of the technologies, tools, and techniques which are helping academics and engineers use SLS ever more effectively and widely. - Provides instructions for how to accurately use SLS for forming - Analyses the numerical simulation methods for key SLS technologies - Addresses the use of SLS for a range of materials, including polymer, ceramic and coated sand powder
