Manipulation of matter at the nanoscale level is the key factor in nanotechnology, and it is considered as a great driving force behind the current industrial revolution since it offers facile and feasible remedies for many problems. Because of the unique characteristic properties of nanomaterials, they can be employed in a wide variety of fields such as agriculture and food technology, catalysis, biomedical applications, tissue culture engineering, and fertilizers. In this regard, characterization of nanomaterials plays a significant role in determining their optical, thermal, and physicochemical properties. Many techniques have been used in nanomaterial characterization, and the most important techniques are discussed in detail in this book with their principles, basic operation procedures, and applications with suitable examples. In summary, this book offers broad content on the most important chemical and structural characterization techniques of nanomaterials. The book offers comprehensive coverage of the most essential topics, including the following: Provides a comprehensive understanding of physical and chemical characterization techniques of nanomaterials Includes details about basic principles of each characterization technique with appropriate examples Covers most of the important characterization techniques that should be known to undergraduate/early career scientists/beginners in materials chemistry Provides all the basic knowledge to understand and carry out the respective analysis of nanomaterials Fulfills the timely need of a book that covers the most important and useful characterization techniques in nanomaterial characterization Up to date, there are no other books/book chapters which discuss most of these nanocharacterization techniques in one segment with all the basic instrumentation details and narrated examples of nanomaterial characterization. In a nutshell, this book will be a great asset to undergraduates/early career scientists/beginners of material science as it provides a comprehensive and complete understanding of most of the techniques used in nanocharacterization tools in a short time. Intended audience is based on science education while specifically focusing on undergraduates/graduate students/early scientists and beginners of chemistry, materials chemistry, and nanotechnology and nanoscience.

With the recent development of in situ transmission electron microscopy (TEM) characterization techniques, the real time study of property-structure correlations in nanomaterials becomes possible. This dissertation reports the direct observations of deformation behavior of Al2O3-ZrO2-MgAl2O4 (AZM) bulk ceramic nanocomposites, strengthening mechanism of twins in YBa2Cu3O7−x (YBCO) thin film, work hardening event in nanocrystalline nickel and deformation of 2wt% Al doped ZnO (AZO) thin film with nanorod structures using the in situ TEM nanoindentation tool. The combined in situ movies with quantitative loading-unloading curves reveal the deformation mechanism of the above nanomaterial systems. At room temperature, in situ dynamic deformation studies show that the AZM nanocomposites undergo the deformation mainly through the grain-boundary sliding and rotation of small grains, i.e., ZrO2 grains, and some of the large grains, i.e., MgAl2O4 grains. We observed both plastic and elastic deformations in different sample regions in these multi-phase ceramic nanocomposites at room temperature. Both ex situ (conventional) and in situ nanoindentation were conducted to reveal the deformation of YBCO films from the directions perpendicular and parallel to the twin interfaces. Hardness measured perpendicular to twin interfaces is ~50% and 40% higher than that measured parallel to twin interfaces, by ex situ and in situ, respectively. By using an in situ nanoindentation tool inside TEM, dynamic work hardening event in nanocrystalline nickel was directly observed. During stain hardening stage, abundant Lomer-Cottrell (L-C) locks formed both within nanograins and against twin boundaries. Two major mechanisms were identified during interactions between L-C locks and twin boundaries. Quantitative nanoindentation experiments recorded during in situ experiments show an increase of yield strength from 1.64 to 2.29 GPa during multiple loading-unloading cycles. In situ TEM nanoindentation has been conducted to explore the size dependent deformation behavior of two different types (type I: ~ 0.51 of width/length ratio and type II: ~ 088 ratio) of AZO nanorods. During the indentation on type I nanord structure, annihilation of defects has been observed which is caused by limitation of the defect activities by relatively small size of the width. On the other hand, type II nanorod shows dislocation activities which enhanced the grain rotation under the external force applied on more isotropic direction through type II nanorod.

The techniques and methods that can be applied to materials characterization on the microscale are numerous and well-established. Divided into two parts, Characterization of Nanostructures provides thumbnail sketches of the most widely used techniques and methods that apply to nanostructures, and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. Section I: Techniques and Methods overviews the physical principles of the main techniques and describes those operational modes that are most relevant to nanoscale characterization. It provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The section covers both mainstream and less commonly used techniques. Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deals with the methods for materials characterization of generic types of systems, using carefully chosen illustrations from the literature. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterization. The volume concludes with a series of flow charts and brief descriptions of tactical issues. The authors focus on the needs of the research laboratory but also address those of quality control, industrial troubleshooting, and online analysis. Characterization of Nanostructures describes those techniques and their operational modes that are most relevant to nanoscale characterization. It is especially relevant to systems of different dimensionalities and functionalities. The book builds a bridge between generalists, who play vital roles in the post-disciplinary area of nanotechnology, and specialists, who view themselves as more in the context of the discipline.
