Book Description
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.

Book Description
Metal Oxide Nanoparticles in Organic Solvents discusses recent advances in the chemistry involved for the controlled synthesis and assembly of metal oxide nanoparticles, the characterizations required by such nanoobjects, and their size and shape depending properties. In the last few years, a valuable alternative to the well-known aqueous sol-gel processes was developed in the form of nonaqueous solution routes. Metal Oxide Nanoparticles in Organic Solvents reviews and compares surfactant- and solvent-controlled routes, as well as providing an overview of techniques for the characterization of metal oxide nanoparticles, crystallization pathways, the physical properties of metal oxide nanoparticles, their applications in diverse fields of technology, and their assembly into larger nano- and mesostructures. Researchers and postgraduates in the fields of nanomaterials and sol-gel chemistry will appreciate this book’s informative approach to chemical formation mechanisms in relation to metal oxides.

Book Description
Nanostructured Anodic Metal Oxides: Synthesis and Applications reviews the current status of fabrication strategies that have been successfully developed to generate nanoporous, nanotubular and nanofibrous anodic oxides on a range of metals. The most recent achievements and innovative strategies for the synthesis of nanoporous aluminum oxide and nanotubular titanium oxide are discussed. However, a special emphasis is placed on the possibility of fabrication of nanostructured oxide layers with different morphologies on other metals, including aluminum titanium, tantalum, tin, zinc, zirconium and copper. In addition, emerging biomedical applications of synthesized materials are discussed in detail. During the past decade, great progress has been made both in the preparation and characterization of various nanomaterials and their functional applications. The anodization of metals has proven to be reliable for the synthesis of nanoporous, nanotubular and nanofibrous metal oxides to produce a desired diameter, density, aspect ratio (length to diameter) of pores/tubes, and internal pore/tube structure. - Provides an in-depth overview of anodization techniques for a range of metals - Explores the emerging applications of anodic metal oxides - Explains mechanisms of formation valve metal oxides via anodization

Book Description
Synthesis of nanoparticles consisting of two major routes, namely physical and chemical routes. In physical route one may nsider ‘top-down’ approach which starts from solid and confining it to a limited size. On the other hand, one may consider ‘bottom-up’ approach which starts from molecular system and expands its size. In case of chemical route, the wet chemical technique for the synthesis of nanoparticles includes sol-gel, combustion, co- recipitation, hydrothermal, microwave etc. By conventional solid state route, it is not possible to obtain a nano sized powder because initial sizes of the reactants are much larger. A major challenge encountered in the synthesis of nanoparticles is the poor control over stoichiometry at the nano level. Although the solid state route is simple, this technique suffers from major drawbacks like weak reactivity of the startingmaterials and the poor homogeneity of the product.

Book Description
The experimental teaching of materials science and engineering (MSE) is important because the comprehensive applications and the practical knowledge of the professionals are not only an important way for undergraduate students to grasp the knowledge but also to understand the purpose of the study. In order to cultivate students' ability to solve complex engineering problems, more comprehensive experiments should be designed.Besides the essential basic experiments in the first few chapters, most of the experiments designed in this book are comprehensive, hence the title. This book breaks the boundaries in the experimental courses of MSE. The experiments in this book are modularized into five parts, including preliminary exploration of materials science and engineering, fundamentals of chemistry and crystallography, material properties, material preparation and treatment, and material applications. Besides the experiments, the appendices will describe the most relevant aspects of experimental safety, error, and data presentation in a general way. The contents and requirements of the experimental report are suggested. At the end of each chapter, a list of books, journal articles, and websites is provided for extended reading on the topics covered in the chapter.This book covers the main contents of experimental courses of MSE. The experiments cover the forefront of scientific research and the materials industry with appropriate modification. It intends to serve as a textbook for undergraduate students and aims to help teachers find a wide enough variety of experiments to construct in an experimental course.

Book Description
This indispensable handbook provides comprehensive coverage of the current state-of-the-art in inorganic, organic, and composite aerogels – from synthesis and characterization to cutting-edge applications and their potential market impact. Built upon Springer’s successful Aerogels Handbook published in 2011, this handbook features extensive revisions and timely updates, reflecting the changes in this fast-growing field. Aerogels are the lightest solids known to man. Up to 1000 times lighter than glass and with a density only four times that of air, they possess extraordinarily high thermal, electrical, and acoustic insulation properties, and boast numerous entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to incorporate non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal, and ceramic materials. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation, and household uses are being developed. Readers of this fully updated and expanded edition will find an exhaustive source for all aerogel materials known today, their fabrication, upscaling aspects, physical and chemical properties, and the most recent advances towards applications and commercial use. This key reference is essential reading for a combined audience of graduate students, academic researchers, and industry professionals.

Book Description
Recent studies indicate that China accounts for about 96 percent of the world's supply of rare earth materials (REMs). With REMs becoming increasingly important for a growing number of high-tech applications, appropriate action must be taken to mitigate the effects of a shortage of critical REMs in defense systems and components.Bringing together i
