Natriuretic Peptides : The Hormones of the Heart

The rapid knowledge in the field of neuro-humoral regulation of cardiovascular pathophysiology is changing the picture of current diagnosis and treatment of cardiac patients. The emerging conceptual revolutionary idea is that heart acts not as a pump, merely, but as a "gland", that is as a regulator of circulatory homeostasis and salt-water balance. Cardiovascular pathophysiology has to be written, indeed, on this basis: this physiology textbook gives an up-to-date description of the complexity and novelty of actual knowledge, with all its potential clinical implications.

Nanostructures : Fabrication and Analysis

The main theme of this book is the exploration the underlying physical laws that permit the fabrication of nanometer-scale structures. As researchers attempt to fabricate nanometer-scale structures which do not exist per se, they must still employ the natural laws to fabricate them through processes such as self-assembly. So it turns out that our techniques for fabrication of nanometer-scale structures are not artificial but actually rely on the natural laws. We even find that nanometer-scale structures, e.g. fullerenes, are fabricated in nature beneath the surface of the Earth. This fact may be called the ubiquity of the nanometer-scale structures. The topics presented in the book include: scanning probe-related and near-field techniques, nanolithography, self assembling and design of novel nanostructures, as well as new nanodevices and their application.

Nanostructured Materials by High-Pressure Severe Plastic Deformation

Recently, it was reported that nanostructured materials processed under high pressure by HPT and ECAP have an extraordinary combination of both high strength and high ductility, which are two desirable, but rarely co-existing properties. These findings indicate that high-pressure is a critical factor that can be employed to process nanostructured materials with superior mechanical, and possibly also physical, properties. It is the objective of this workshop to review our current knowledge, identify issues for future research, and discuss future directions on the processing and properties of nanostructured materials via SPD techniques, with a special emphasis on high-pressure effects.

Nanoscaled Semiconductor-on-Insulator Structures and Devices

This proceedings volume constitutes an archive of the contributions of the key-speakers who attended the NATO Advanced Research Workshop on “Nanoscaled Semiconductor-On-Insulator Structures and devices” held in the Tourist and Recreation Centre “Sudak” (Crimea, Ukraine) from 15 to 19 October 2006. The semiconductor industry has sustained a very rapid growth during the last three decades through impressive technological developments which have resulted in products with higher performance and lower cost per function. After many years of development it is now confidently predicted that semiconductor-on-insulator materials will enter and increasingly be used by manufacturing industry. The wider use of semiconductor (es- cially silicon) on insulator materials will not only enable the benefits of these materials to be demonstrated but, also, will drive down the cost of substrates which, in turn, will stimulate the development of other novel devices and applications.

Nanoscale Assembly : Chemical Techniques

Recent advances have pushed the limits of lithography firmly into the sub-100 nm domain, with smallest feature sizes around 10 nm. However, compared to living organisms, devices fabricated using nanolithography are not nearly as complex, as they are essentially 2D and contain only a limited number of chemical elements. For centuries, Nature has been a major inspiration for science. First of all to learn how Life functions at cellular level, but increasingly, as a blueprint for designing non-natural devices where the building blocks and their assembly are inspired by biological examples. The key tool in translating these examples into the domain of engineering, has been self-assembly or self-organization. This book gathers a spectrum researchers who have not only furthered our knowledge of self-assembly using small molecules, polymers and colloidal particles as building blocks, but who have also shown it to be a practical tool in the assembly of an astonishing variety of devices, ranging from molecular electronics to biosensors.
