This thesis investigates the effect of the magnetic field on propagating surface plasmon polaritons (SPPs), or surface plasmons for short. Above all, it focuses on using the magnetic field as an external agent to modify the properties of the SPPs, and therefore achieving active devices. Surface plasmons are evanescent waves that arise at metal-dielectric interfaces. They can be strongly confined (beyond the light diffraction limit), and provide a strong enhancement of the electromagnetic field at the interface. These waves have led to the development of plasmonic circuitry, which is a key candidate as an alternative to electronic circuitry and traditional optical telecommunication devices, since it is faster than the former and less bulky than the latter. Adopting both a theoretical and an experimental point of view, the book analyzes the magnetic modulation in SPPs by means of an interferometer engraved in a multilayer combining Au and Co. In this interferometer, which acts like a modulator, the SPP magnetic modulation is studied in detail, as are the parameters that have a relevant impact on it, simple ways to enhance it, its spectral dependence, and the highly promising possibility of using this system for biosensing. The thesis ultimately arrives at the conclusion that this method can provide values of modulations similar to other active methods used in plasmonics.

Calixarenes have been widely exploited in all areas of supramolecular chemistry over the past three decades and many recent developments have concerned their applications in the production of chemical entities with the dimensions of nanometres, as in nanochemistry. This book will provide a timely review of both what is known and the exciting prospects provided by calixarenes in this field. The book will comprise several review articles defining the importance of calixarenes as reagents in nanochemistry. It is expected that Calixarenes in the Nanoworld will be well-received by: universities, research institutions, industries engaged in the production of high-tech materials.
The book includes the research papers presented in the final conference of the EU funded SARISTU (Smart Intelligent Aircraft Structures) project, held at Moscow, Russia between 19-21 of May 2015. The SARISTU project, which was launched in September 2011, developed and tested a variety of individual applications as well as their combinations. With a strong focus on actual physical integration and subsequent material and structural testing, SARISTU has been responsible for important progress on the route to industrialization of structure integrated functionalities such as Conformal Morphing, Structural Health Monitoring and Nanocomposites. The gap- and edge-free deformation of aerodynamic surfaces known as conformal morphing has gained previously unrealized capabilities such as inherent de-icing, erosion protection and lightning strike protection, while at the same time the technological risk has been greatly reduced. Individual structural health monitoring techniques can now be applied at the part-manufacturing level rather than via extending an aircraft's time in the final assembly line. And nanocomposites no longer lose their improved properties when trying to upscale from neat resin testing to full laminate testing at element level. As such, this book familiarizes the reader with the most significant develo pments, achievements and key technological steps which have been made possible through the four-year long cooperation of 64 leading entities from 16 different countries with the financial support of the European Commission.
Catalysts, heterogeneous, homogeneous and enzyme, are usually nanoparticles. These are of vital for the functioning of the human body, for photosynthesis, and for producing fuels and chemicals in the petroleum and chemical industries. Interest in nanoscience and in nanotechnology in recent years focused attention on the opportunity to develop catalysts that exhibit 100% selectivity for a desired product, thus removing byproducts and eliminating waste. This type of selective process is often called green chemistry or green technology. This book is mainly based on the first and second symposia on Nanotechnology 51 in Catalysis which were held in spring 2001 at the ACS 221 National Meeting in San Diego, CA, and in fall 2002 at the ACS 2241h National Meeting in Boston, MA, respectively. We also extended our invitation to those who did not attend the meetings to contribute chapters where we saw a need to round out the scope of the topic. All chapters were peer-reviewed prior to final acceptance. We believe that the additional chapters and the peer-review significantly improved the quality of the book. In the summer of 2000 when we first proposed to organize a symposium on Nanotechnology in Catalysis to the ACS Secretariat of Catalysis and Surface Science (CATL), we received strong support from Dr. Nancy B. Jackson, then General Secretary of CATL. The symposium was enthusiastically received by the catalysis community. On the first day of the symposium, the conference room could not hold all the attendees.
Representing the first text to cover this exciting new area of research, this book will describe synthesis techniques of CNWs, their characterization and various expected applications using CNWs. Carbon-nanowalls (CNWs) can be described as two-dimensional graphite nanostructures with edges comprised of stacks of plane graphene sheets standing almost vertically on the substrate. These sheets form a wall structure with a high aspect ratio. The thickness of CNWs ranges from a few nm to a few tens of nm. The large surface area and sharp edges of CNWs may prove useful for a number of applications such as electrochemical devices, field electron emitters, storage materials for hydrogen gas, catalyst support. In particular, vertically standing CNWs with a high surface-to-volume ratio, serve as an ideal material for catalyst support for fuel cells and in gas storage materials.

The three major technology areas electronics, photonics, and solar energy are linked on the basis of similar applications of nanostructured materials in research and development. By bridging the materials physics and chemistry at the atomic scale with device and system design, integration, and performance requirements, tutorial chapters from worldwide leaders in the field provide a coherent picture of theoretical and experimental research efforts and technology development in these highly interdisciplinary areas."
Despite advances in the long-range electrostatic double-layer force, which depends strongly on ionic strength in water by using theoretical models such as DLVO (Derjaguin, Landau, Verwey, and Overbeek), the structure of confined water in air still remains widely unknown and has led to a variety of unexplained phenomena. This book bridges that gap by introducing a newly developed scanning probe miscroscopy (SPM) approach, which enables one to probe confined water at the molecular and atomic scale. Written by the developer of SPM, this book covers this new approach, as well as original approaches to addressing general interfacial water issues. It also introduces the cantilever-based optical interfacial force microscope (COIFM), which was invented by the author along with the methodology. The improved understanding will contribute to liquid-based nano- and bio-technologies such as lab-on-a-chip technologies, nanofluidic devices, dip-pen nanolithography, nano-oxidation, water-based granular interactions, liquid-based nanolubricants, hydration layers in biopolymers, manipulation of biomolecules, protein folding, stability of colloid suspensions, enzyme activity, swelling in clays, development of bioactive surfaces, water columns and ion channeling in membranes and scanning probe microscopy (SPM). It will also contribute to the improved performance of moving components in silicon-based micro-electro-mechanical system (MEMS) devices, where water plays a key role in interfacial interactions.

This thesis presents original research on how to seamlessly integrate electronics with living biological systems. Jia Liu has used silicon nanowires as active sensors to investigate biological signals at the cellular level. He has also designed nanoelectronic networks into flexible, three-dimensional (3D) and macroporous architectures, which mimic the structure of tissue scaffolds for in vitro 3D integrations with synthetic tissues and in vivo implantation by means of syringe injection. Importantly, the results demonstrate 3D interpenetrations of nanoelectronic networks with neural networks, 3D mapping of tissue activity and long-term implantation with minimal immunoresponses. Further, the book discusses potential applications for pharmacological studies, brain activity mapping and nanoelectronics enabled therapies. The findings presented here have gained wide recognition, including a top research ranking by Chemical & Engineering News and being listed among Scientific American's 10 world changing ideas in 2015.
This book collects 42 peer-reviewed papers presented in the NATO Advanced Research Workshop on Nanostructured Materials by High-Pressure Severe Plastic Deformation, held in Donetsk, Ukraine, September 22-24, 2004. 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. During the 3-day workshop, about 60 scientists from 12 countries presented 60 papers. Over 20 keynote presentations were given by distinguished scientists in this field. Papers in this book cover areas of high pressure effect on the nanostructure and properties of SPD-processed materials, fundamentals of nanostructured materials, development of high-pressure SPD technologies for commercializations, recent advances of SPD technologies as well as applications and future markets of SPD-processed nanostructured materials

These tiny structures could offer architectural designs for the cities of the future. The authors explore the foam-like carbon structures, which relate to schwarzites and which are infinite periodic minimal surfaces of negative curvature. They show that the periodicity of close repeat units of such structures is evident not only in these formations but also in all of the carbon allotropes. The text provides literature and data on the field of nanostructure periodicity and the authors own results on nanostructure building and energy calculations.
This book presents a complete state of the art for different types of nanomaterial, their environmental fate, and their use in textile waste remediation. Nano-engineered materials including nanoparticles, nanofibers, nanotubes have been used extensively for a variety of applications. Environmental concerns have been noted mainly due to the discharge of textile waste. Nanotechnology is fast growing on research and bringing sustainable solution in minimizing the waste. This also minimizes the risk of exposure and health hazards. With the development of industry, environmental pollution and energy shortage have raised awareness of a potential global crisis. So, it is urgent to develop a simple and effective method to address these current issues. Nano-engineered materials can be better solution in finding solution of environmental sustainability more specific to the textile waste remediation. Nano-engineered materials have emerged as pioneering photocatalysts and account for most of the current research in this area. This can provide large surface areas, diverse morphologies, abundant surface states, and easy device modeling, all of which are properties beneficial to photodegradation. Furthermore, the stability and cost of nano-engineered materials are critical factors. Therefore, it is a challenge of great importance to identify and design nano-engineered materials that are efficient, stable, and abundant for the remediation of textile waste.
Particulate products make up around 80% of chemical products, from all industry sectors. Examples given in this book include the construction materials, fine ceramics and concrete; the delicacies, chocolate and ice cream; pharmaceutical, powders, medical inhalers and sun screen; liquid and powder paints. Size distribution and the shape of the particles provide for different functionalities in these products. Some functions are general, others specific. General functions are powder flow and require at the typical particulate concentrations of these products that the particles cause adequate rheological behavior during processing and/or for product performance. Therefore, this book addresses particle packing as well as its relation to powder flow and rheological behavior. Moreover, general relationships to particle size are discussed for e.g. color and sensorial aspects of particulate products. Product-specific functionalities are often relevant for comparable product groups. Particle size distribution and shape provide, for example, the following functionalities: - dense particle packing in relation to sufficient strength is required in concrete construction, ceramic objects and pharmaceutical tablets - good sensorial properties (mouthfeel) to chocolate and ice cream - effective dissolution, flow and compression properties for pharmaceutical powders - adequate hiding power and effective coloring of paints for protection and the desired esthetical appeal of the objects - adequate protection of our body against sun light by sunscreen - effective particle transport and deposition to desired locations for medical inhalers and powder paints. Adequate particle size distribution, shape and porosity of particulate products have to be achieved in order to reach optimum product performance. This requires adequate management of design and development as well as sufficient knowledge of the underlying principles of physics and chemistry. Moreover, flammability, explosivity and other health hazards from powders, during handling, are taken into account. This is necessary, since great risks may be involved. In all aspects, the most relevant parameters of the size distribution (and particle shape) have to be selected. In this book, experts in the different product fields have contributed to the product chapters. This provides optimum information on what particulate aspects are most relevant for behavior and performance within specified industrial products and how optimum results can be obtained. It differs from other books in the way that the critical aspects of different products are reported, so that similarities and differences can be identified. We trust that this approach will lead to improved optimization in design, development and quality of many particulate products."
