Book Description
Englisch: The present study displays new methods for the synthesis of structured inorganic materials with novel architecture in micrometer and nanometer range. The main role of the special design is based on template induced precipitation of inorganic materials on self - assembled monolayers. Suitable substrates are gold - coated glass slides and gold colloids, which show behavior like molecules, and at the same time they still display many properties of extended solids. On these substrates thiols can be adsorbed to form a monomolecular layer, which interferes with the physical properties of the obtained surface. The synthesis of special thiols, tuned for the special need in current applications, represents a main focus in the present study. Gold coated glass as templates were used in the first part of this work. The precipitation of calcium carbonate was examined due to the film thickness of the adsorbed monolayer. Aragonite, one of the three important calcium carbonate phases, is formed on self assembled monolayers under ambient conditions using a polyaromatic amide surface with film thickness in ranges of 5 - 400 nm as nucleation template. The parameters that could be controlled were the polaramide chain length, the?-substituent at the polymer, the connection to the gold surface using different amino thiols and the crystallization temperature. Here, the control of thickness of a polyaramide monolayer during its preparation using a step polymerization technique is presented the first time. By using self - assembled monolayers (SAM) of alkane thiols gold-coated glass slides have been patterned. Through the use of a special thiol terminated with a styrene monomer, microstructures of 5 to 10 æm width and 70 Å height have been formed on the surface by graft polymerization of styrene. These patterned gold slides have then been used to template the precipitation of thin titania films from ethanolic solutions of titanium isopropoxide to create microstructured architectu.

Book Description
The “bioelectronic nose”, the device which has a similar function to the human smell sensing system, can be realized by combining the olfactory cells or receptors with nanotechnology. In the last two decades, much has been learned about the smell sensing mechanism in biological systems. With knowledge about the biological olfactory system and the techniques for the expression of biological receptor proteins, we are able to utilize biological materials and systems to mimic the biological olfactory system. In addition to the advances in biological and biotechnological area, nanotechnology has progressed to a great degree. The bioelectronic nose is a good example of the integration of biotechnology and nanotechnology. This book describes basic biological sciences of the olfactory system, biotechnology for the production of olfactory biological elements, and nanotechnology for the development of various sensing devices. The purpose of this book is to provide the reader with a concept, basic sciences, fundamental technologies, applications, and perspectives of the bioelectronic nose.

Book Description
Today's shortages of resources make the search for wear and corrosion resistant materials one of the most important tasks of the next century. Since the surface of a material is the location where any interaction occurs, it is that there the hardest requirements on the material are imposed: to be wear resistant for tools and bearings; to be corrosion resistant for turbine blades and tubes in the petrochemical industry; to be antireflecting for solar cells; to be decorative for architectural panels and to combine several of these properties in other applications. Surface engineering is the general term that incorporates all the techniques by which a surface modification can be accomplished. These techniques include both coating and modification of the surface by ion implantation and laser beam melting. In recent years a continuously growing number of these techniques were developed to the extent that it became more and more difficult to maintain an overlook and to understand which of these highly differentiated techniques might be applied to resolve a given surface engineering problem. A similar development is also occuring for surface characterization techniques. This volume contains contributions from renowned scientists and engineers to the Eurocourse the aim of which was to inform about the various techniques and to give a comprehensive survey of the latest development on this subject.

Book Description
With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.
