NASAs Scientist-Astronauts
Mounting pressure in the early 1960s from the National Academy of Sciences (NAS) to study ways of expanding the role of astronauts to conduct science on future space missions led to NASA’s conclusion that flying scientifically trained crewmembers would generate greater returns from each mission. NASA and industry studies continued investigating possibilities that could lead to the eventual creation of the first space stations using surplus Apollo hardware, through the Apollo Applications Programme (AAP).

Nanotechnologies, Hazards and Resource Efficiency : A Three-Tiered Approach to Assessing the Implications of Nanotechnology and Influencing its Development
Nanotechnology is frequently described as an enabling technology and 1 fundamental innovation, i.e. it is expected to lead to numerous innovative developments in the most diverse fields of technology and areas of app- cation in society and the marketplace. The technology, it is believed, has the potential for far-reaching changes that will eventually affect all areas of life. Such changes will doubtlessly have strong repercussions for society and the environment and bring with them not only the desired and intended effects such as innovations in the form of improvements to products, pr- esses and materials; economic growth; new jobs for skilled workers; relief for the environment; and further steps toward sustainable business, but also unexpected and undesirable side effects and consequences.
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 and advanced materials for applications in sensor, optoelectronic and photovoltaic technology ; Proceedings of the NATO Advanced Study Institute on nanostructured and advanced materials for applications in sensors, optoelectronic and photovoltaic technology ; Sozopol, Bulgaria, 6-17 September 2004
Nanotechnology is an emerging scientific field receiving significant worldwide attention. On a nanometer scale, materials or structures may possess new and unique physical properties. Some of these are now known to the scientific community, but there may well be many properties not yet known to us, rendering it as a fascinating area of research and a suitable subject for a NATO ASI. Yet another aspect of the field is the possibility for creating meta-stable phases with unconventional properties and the ultra-miniaturization of current devices, sensors, and machines. Such nanotechnological and related advanced materials have an extremely wide range of potential applications, viz. nanoscale electronics, sensors, optoelectronics, photonics, nano-biological systems, na- medicine, energy storage systems, etc. This is a wide-ranging subject area and therefore requires the formation of multi-disciplinary teams of physicists, chemists, materials scientists, engineers, molecular biologists, pharmacologists, and others to work together on the synthesis and processing of materials and structures, the understanding of their physical properties, the design and fabrication of devices.

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 Transistors : Device Physics, Modeling and Simulation
The book is a useful reference for senior-level or graduate-level courses on nanoelectronics, modeling and simulation. Chapter 1 reviews some basic concepts, and Chapter 2 summarizes the essentials of traditional semiconductor devices, digital circuits, and systems. This material provides a baseline against which new devices can be assessed. Chapters 3 and 4 present a non-traditional view of the MOSFET using concepts that are valid at nanoscale. Chapter 5 applies the same concepts to nanotube FET as an example of how to extend the concepts to revolutionary nanotransistors. Chapter 6 explores the limits of devices by discussing conduction in single molecules.
Nanoscale Phenomena : Basic Science to Device Applications
Nanotechnology is the result of the continuing technological trend toward device miniaturization and the characterization, manipulation, and fine control of structure and function at diminishing length scales. A large class of nanoscale materials can be stable even though they are far from the lowest-energy thermodynamic state, and many possess novel properties unattainable in bulk. These trends are supported by the increasing sophistication of characterization and fabrication tools such as the scanning tunneling microscope and the transmission electron microscope, which allow the resolution and manipulation of single atoms and molecules.

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.
