One of the directions of nanotechnology is the production of nanopowders (NPs). Nanopowders, according to the currently widely used classification of nanomaterials, belong to zero-dimensional systems in which the limitation of wave functions occurs in all three directions. Biological methods are considered the most environmentally friendly way to synthesize NPs, but the possibility of biological contamination with mutated microorganisms cannot be ruled out.This book presents a new method for producing simple and complex metal oxide and fluoride NPs, based on the “evaporation-condensation” process using pulsed electron beam evaporation. It presents the results of more than 10 years of study of the characteristics of NPs produced using the aforementioned method. This eco-friendly method ensures the production of clean NPs, which are mesoporous and suitable for use in various applications such as medicine, spintronics, optoelectronics, dosimeters, photocatalysis, semiconductors, and ultraviolet and blue lasers. Importantly, these NPs have the potential to be used as a drug delivery system and in the creation of new nanostructures that do not contain noble metals. The book will be useful for the researchers in macromolecular science, nanotechnology, chemistry, biology, and medicine, especially those with an interest in drug delivery or cancer therapy.

The development of the technique of generating high-voltage nanosecond pulses based on the effect of a nanosecond opening switch in semiconductor diodes gave the prerequisites for the development of nanosecond electron accelerators with a pulse-periodic operation mode. Such accelerators generate high-intensity large beams that have a strong biological effect. However, to create industrial accelerators and implement highly efficient radiation technologies, it is necessary to provide the required range of beam parameters, high reliability, and long life of accelerators.This book describes the principles and design of repetitive nanosecond electron accelerators, as well as the development technologies and specific radiation technologies based on them. It discusses the application of the created accelerators in various branches of science and technology, in particular, for radiation sterilization and disinfection of medical and food products, correction of defects in solids, and radiation-chemical technologies. The book also covers the issues encountered in measuring the parameters of electron beams, monitoring parameters, and automating the control of accelerators.
