Radiation Synthesis Of Materials And Compounds

Researchers and engineers working in nuclear laboratories, nuclear electric plants, and elsewhere in the radiochemical industries need a comprehensive handbook describing all possible radiation-chemistry interactions between irradiation and materials, the preparation of materials under distinct radiation types, the possibility of damage of material

This book gives a progress report on the many and original contributions of radiation chemistry to the fundamental knowledge of the vast domain of chemical reactions and its applications. Radiation chemistry techniques indeed make it possible to elucidate detailed physicochemical mechanisms in inorganic and organic chemistry (including in space) and in biochemistry. Moreover, this comprehension is applied in materials science to precisely control syntheses by radiation, such as radiopolymerisation, radiografting, specific treatment of surfaces (textiles, paintings, inks, etc.), synthesis of complex nanomaterials, degradation of environmental pollutants and radioresistance of materials for nuclear reactors. In life sciences, the study of the effects of radiation on biomacromolecules (DNA, proteins, lipids) not only permits the comprehension of normal or pathological biological mechanisms, but also the improvement of our health. In particular, many advances in cancer radiotherapy, in the radioprotection of nuclear workers and the general population, as well as in the treatment of diseases and the radiosterilization of drugs, could be obtained thanks to this research. Abundantly illustrated and written in English by top international specialists who have taken care to render the subjects accessible, this work will greatly interest those curious about a scientific field that is new to them and students attracted by the original and multidisciplinary aspects of the field. At a time when radiation chemistry research is experiencing spectacular development in numerous countries, this book will attract many newcomers to the field.

This book presents the applications of high-energy beam radiation for synthesis and processing of polymeric materials. It addresses fundamental nature of high energy i.e., ionizing radiations and interaction with monomers and polymers leading to a wide variety of products such as tyres, textiles, shape memory polymers, polymers for aviation and space applications, polymeric biomaterials and natural rubber latex. It discusses general principles and techniques of preparation of polymeric materials including polymer blends, composites and nanocomposites. It also includes the topic of radiation-assisted recycling of polymers through breaking of covalent bonds. This book will be useful for students, researchers and professionals in the areas of polymers science and technology, radiation technology, electron beam technology, gamma radiation technology, advanced materials technology, biomaterials technology, nanotechnology, membrane science technology and environmental science.

This book presents a summary of the research progress in the field of petroleum radiation processing, which has produced technology that offers effective and economic solutions for some pressing oil refining challenges. It provides a systematic description of the most important experiments on radiation cracking for different types of petroleum feedstock, including crude oils, heavy oil residues, and bitumen. The book provides a detailed introduction to radiation methods based on radiation-thermal and low-temperature cracking of hydrocarbons, emphasizing high-viscous oil feedstocks that are difficult to process by conventional methods.

Biopolymer Grafting: Applications presents the latest research and developments in the practical application of these methods in industry, both to enable polymer scientists and engineers to keep up with the latest research trends, as well as to propose ideas for further research and application. Research into bio-based polymers has become increasingly prevalent. However, due to challenges related to the properties of these materials compared to synthetic polymers—such as their resistance to chemicals or weather—uptake has not dramatically increased yet. As a result, improvements in surface modification of bio-polymers through graft copolymerization are enormously important, because they will widen the scope of their applications. Relevant industries for application of these methods include automotive, construction, food, packaging, agriculture, textiles and paper. This book provides an overview of the developments made in the area of biopolymer-based graft polymers. Advantages, disadvantages and suggestions for future works are discussed, assisting materials scientists and researchers in mapping out the future of these new "green" materials through value addition to enhance their use. Helps researchers and product developers understand the applications and limitations of biopolymer copolymers or copolymers of natural polymers Offers a roadmap to future applications development in a range of different industries, including automotive, biomedical and packaging Increases familiarity with a range of biopolymer grafting processes, enabling materials scientists and engineers to improve material properties and widen the range of potential biopolymer applications

This collection of selected review papers focuses on topics such as digital radiation sensors and nanosensory systems for nanotechnology applications and integrated X-ray/PET/CT detectors; nanophosphors and nanocrystal quantum dots as X-ray radiation sensors; the luminescence efficiency of CdSe/ZnS QD and UV-induced luminescence efficiency distribution; investigations devoted to the quantum and multi-parametrical nature of disasters and the modeling thereof using quantum search and quantum query algorithms; sum-frequency-generation, IR fourier and raman spectroscopy methods; as well as investigations into the vibrational modes of viruses and other pathogenic microorganisms aimed at creating optical biosensory systems. This is followed by a review of radiation resistant semiconductor sensors and magnetic measurement instrumentation for magnetic diagnostics of high-tech fission and fusion set-ups and accelerators; the evaluation of the use of neutron-radiation, 10B-enriched semiconducting materials as thin-film, highly reliable, highly sensitive and fast-acting robust solid-state electronic neutron-detectors; and the irradiation of n-Si crystals with protons, which converts the “metallic” inclusions to “dielectric” ones in isochronous annealing, therefore leading to opto/micro/nanoelectronic devices, including nuclear radiation nanosensors. The book concludes with a comparative study of the nitride and sulfide chemisorbed layers; a chemical model that describes the formation of such layers in hydrazine-sulfide and water sodium sulfide solution; and recent developments in the microwave-enhanced processing and microwave-assisted synthesis of nanoparticles and nanomaterials using Mn(OH)2.
