Materials science application fields

There already exist a few books written on field ion microscopy. Most of these either were published before 1970 when most works were concerned with techniques and methods, or are later ones which emphasize applications to materials science. While some of the basic principles of field ion microscopy remain unchanged from those twenty years ago, when Muller and I wrote a book on the subject, there have been many important new theoretical and technical developments and applications, and also many more detailed studies of a variety of problems in surface science and materials science. In the book just referred to, the subject of atom-probe field ion microscopy was only barely touched. This is of course where most of the new developments are made, and is also the instrument now most actively employed by investigators in the field. In the present volume I try to emphasize basic principles of atom-probe field ion microscopy, field ion emission and applications to surface science. As books emphasizing applications to materials science already exist, only selected topics in this area are presented here. They are used to illustrate the various capabilities of atom-probe field ion microscopy in materials science applications. 

This and many other fields, using both solid-state and solution-phase synthetic procedures, are expected to benefit significantly from the use of combinatorial technologies. Unprecedented applications will surely appear due to the increasing popularity of materials science applications in the combinatorial chemistry scientific arena. 

The combination of metal ions and appropriate ligands to form macrocyclic, cage-like, and extended network structures has become a powerful tool for the construction of systems having cavities, pores, or channels, and is currently one of the most important topics in chemical and material sciences. Applications are visualized for a wide range of fields, such as ion and molecular recognition, sorption, filtration,... 

In this chapter, we will review near-field optical methods and their applications to problems in biology and materials science. Near-field techniques provide nanometer spatial resolution by overcoming the Abbe diffraction Hmit, and can be used to investigate many types of sample in situ. Here, emphasis is placed on near-field methods that provide vibrational information (i.e., molecular fingerprints ) of the analytes. Finally, the current challenges faced by these methods and their potential in nanoscale chemical analysis in the near future are discussed. 

In this chapter we have shown how force fields can be utilized in materials science applications. There are similarities between force fields used in life science and in materials science. Owing to the variety of molecules studied in materials science, however, there are several complementary approaches to modeling such systems. Molecular mechanics force fields as used in life science (i.e., in biomolecules) can also be applied to organic materials such as polymers or liquid crystals. Ionic materials such as oxides are better described by means of ion pair or shell model potentials. For some systems with ionic as well as covalent character in their bonds (e.g, zeolites), both approaches are feasible. 

Tetrazoles with a similar structure to triazoles tolerate various chemical environments. They are stable under oxidizing and reducing conditions as well as strongly acidic and basic media. Thus, this class of heterocycles presently plays a crucial role in the field of coordination chemistry, material science application and medicinal chenustry. The pharmacokinetic potential of tetrazoles, frequently used as metabolically stable surrogates of carboxylic acids, makes the synthesis of this nitrogen-rich heterocycle particularly fascinating. 

Auger electron spectroscopy has become one of the most important tools for the investigation of interfaces in the field of materials science. In fact, it is probably safe to say that it has found its most widespread application in this field. Because it does not give detailed chemical bonding information about the species on a surface, other techniques such as XPS and UV photoemission are more commonly used for detailed chemical investigations. However, in materials science applications the need is more often to detect the presence of elements on the surface of the solid, and for this application Auger electron spectroscopy is the preferred technique. 

Volume 79 of Advances in Heterocyclic Chemistry commences with an overview of Tellurium-Nitrogen-Containing Heterocycles by I. D. Sadekov and V. I. Minkin of Rostov State University, Russia, andrepresents an update of the review published by the same authors in Volume 58 of Advances, eight years ago. The field has expanded markedly in the recent past, and the compounds show promise in an increasing number of applications, particularly in the material science field. 

The recent development of structurally controlled dendrimers has led to the development of a wide range of new functional macromolecules. These dendrimers were first applied in the fields of chemistry, including catalysis, pharmacology, and materials science [23-26]. More recently there have been several reports of dendrimers having electro active, photoactive, and recognition elements [27-34]. Important applications in photonics have recently been exploited, though the number of reports is still limited.

Another noted and prolific Japanese author in the field of functional dyes, Masaru Matsuoka of the Laboratory of Materials Science, Kyoto Women s University, has written the second chapter, dealing with leuco-quinone dyes. These are the traditional redox leuco systems employed for so many years in the vat dyeing industry, and this chapter is an invaluable review of the chemistry of these systems, drawing on recent mechanistic and structural investigations. Applications considered include not only textile dyeing, but also other more specialized areas, such as hair dyeing, color formers, and photoimaging materials.
