Micro/nano-mechanical systems are a crucial part of the modern world providing a plethora of sensing and actuation functionalities used in everything from the largest cargo ships to the smallest hand-held electronics; from the most advanced scientific and medical equipment to the simplest household items. Over the past few decades, the processes used to produce these devices have improved, supporting dramatic reductions in size, but there are fundamental limits to this trend that require a new production paradigm. The 2004 discovery of graphene ushered in a new era of condensed matter physics research, that of two-dimensional materials. Being only a few atomic layers thick, this new class of materials exhibit unprecedented mechanical strength and flexibility and can couple to electric, magnetic and optical signals. Additionally, they can be combined to form van der Waals heterostructures in an almost limitless number of ways. They are thus ideal candidates to reduce the size and extend the capabilities of traditional micro/nano-mechanical systems and are poised to redefine the technological sphere. This thesis attempts to develop the framework and protocols required to produce and characterise micro/nano-mechanical devices made from two-dimensional materials. Graphene and its insulating analogue, hexagonal boron nitride, are the most widely studied materials and their heterostructures are used as the test-bed for potential device architectures and capabilities. Interlayer friction, electro-mechanical actuation and surface reconstruction are some of the key phenomena investigated in this work.
This volume is the latest of the "Kirchberg-Proceedings". The previous 11 International Winterschools on Electronic Properties of Novel Materials, all held in Kirchberg, Austria, were devoted to conducting polymers, high temperature superconductors, fullerenes, and carbon nanotubes. Fullerenes and nanotubes are still in the center of interest, but the topic of the school and the proceedings is molecular nanostructures in general. The organizers have attempted to treat carbon nanostructures as a special case of molecular nanostructures, which also include silicon clusters, gold clusters, vanadium oxide tubes, and many others. The Winterschool provides a platform for reviewing and discussing new developments in the field of molecular nanostructures and their applications. Materials discussed include fullerenes, fullerene-derived structures, carbonaceous nanotubes, non-carbonaceous nanotubes, layer by layer systems, molecular clusters, new phases of carbon, endohedral compounds and related materials. The book aims to give an overview of the current status of fullerenes, carbon-nanotubes and related molecular nanostructures. The majority of the contributions present the latest results of experiments and calculations conducted in the field. However, about a dozen contain some degree of instructional material which even newcomers will benefit from.
Bringing together nanoscience with stem cell and bacterial cell biology, this thesis is truly interdisciplinary in scope. It shows that the creation of superparamagnetic nanoparticles inside a protein coat, followed by chemical functionalisation of the protein surface, provides a novel methodology for cell magnetisation using incubation times as short as one minute. Crucially, stem cell proliferation and multi-lineage differentiation capacity is not impaired after labelling. Due to the unspecific labelling mechanism, this thesis also shows that the same magnetic protein nanoparticles can be used for rapid bacterial magnetisation. Thus, it is possible to magnetically capture and concentrate pathogens from clinical samples quickly and highly efficiently.
Building on the success of its predecessor, Carbon Nanotubes: Synthesis, Structure, Properties and Applications, this second volume focuses on those areas that have grown rapidly in the past few years. Contributing authors reflect the multidisciplinary nature of the book and are all leaders in their particular areas of research. Among the many topics they cover are graphene and other carbon-like and tube-like materials, which are likely to affect and influence developments in nanotubes within the next five years. Extensive use of illustrations enables you to better understand and visualize key concepts and processes.

Heat transfer laws for conduction, radiation and convection change when the dimensions of the systems in question shrink. The altered behaviours can be used efficiently in energy conversion, respectively bio- and high-performance materials to control microelectronic devices. To understand and model those thermal mechanisms, specific metrologies have to be established. This book provides an overview of actual devices and materials involving micro-nanoscale heat transfer mechanisms. These are clearly explained and exemplified by a large spectrum of relevant physical models, while the most advanced nanoscale thermal metrologies are presented.
This is the first book about functional nanostructures. Nanocrystalline materials exhibit outstanding properties and represent a new class of structural materials having a wide range of applications. In particular, there is considerable interest in developing nanocrystalline materials to be used as functional materials in aerospace applications, automotive industry, wear applications, etc. Future progress in these high technological applications of nanocrystalline materials depends on development of new methods of their fabrication and understanding of the underlying nano-scale and interface effects causing their unique mechanical properties.
The application of nanotechnology in different consumer products has delivered new products with highly desirable properties, but at same time has opened a new window for a wide group of emerging contaminants and a new type of human exposure which needs to be assessed. Most of the current human toxicological information on
nanomaterials comes from nano-sized particles in air, and their
effects via inhalation. Other routes of human exposure, such as
water and food, and the effects on human health and the environment
have been less studied. It is the recent research in these areas
that is highlighted here in one of the first books covering the
analysis and ecotoxicological evaluation of nanomaterials in food
and the environment, with both matrices being of considerable
interest. In addition to providing a global summary of recent
research, this book shows how widely used chromatographic and
spectroscopic methods can be added to the analytical arsenal of
microscopic techniques that have commonly been used to characterize
nanomaterials.

Also of practical use for readers are chapters that describe the basics of porous silicon fabrication and its use in optical sensing and drug delivery applications; how thermal transport is affected in porous materials; how to model diffusion in porous materials; and a unique chapter on an innovative spectroscopic technique used to characterize materials' porosity. This is an ideal book for graduate students, researchers, and professionals who work with porous materials.
Less than twenty years ago photolithography and medicine were total strangers to one another. They had not yet met, and not even looking each other up in the classi?eds. And then, nucleic acid chips, micro?uidics and microarrays entered the scene, and rapidly these strangers became indispensable partners in biomedicine. Asrecentlyastenyearsagothenotionofapplyingnanotechnologytothe?ghtagainstd- ease was dominantly the province of the ?ction writers. Thoughts of nanoparticle-vehicled deliveryoftherapeuticalstodiseasedsiteswereanexerciseinscienti?csolitude,andgrounds for questioning one's ability to think "like an established scientist". And today we have nanoparticulate paclitaxel as the prime option against metastatic breast cancer, proteomic pro?lingdiagnostictoolsbasedontargetsurfacenanotexturing,nanoparticlecontrastagents for all radiological modalities, nanotechnologies embedded in high-distribution laboratory equipment, and no less than 152 novel nanomedical entities in the regulatory pipeline in the US alone. Thisisatransformingimpact,byanymeasure,withclearevidenceoffurtheracceleration, supported by very vigorous investments by the public and private sectors throughout the world. Even joining the dots in a most conservative, linear fashion, it is easy to envision scenarios of personalized medicine such as the following: patient-speci?c prevention supplanting gross, faceless intervention strategies; early detection protocols identifying signs of developing disease at the time when the disease is most easily subdued; personally tailored intervention strategies that are so routinely and inexpensively realized, that access to them can be secured by everyone; technologies allowing for long lives in the company of disease, as good neighbors, without impairment of the quality of life itself.
This book provides a comprehensive description of microsensors for mechanical quantities (flow, pressure, force, inertia) fabricated by silicon micromachining. Since the design of such sensors requires interdisciplinary teamwork, the presentation is made accessible to engineers trained in electrical and mechanical engineering, physics and chemistry. The reader is guided through the micromachining fabrication process. A chapter on microsensor packaging completes the discussion of technological problems. The description of the basic physics required for sensor design includes the mechanics of deformation and the piezoresistive transduction to electrical signals. There is also a comprehensive discussion of resonant sensors, the hydrodynamics and heat transfer relevant for flow sensors, and, finally, electronic interfacing and readout circuitry. Numerous up-to-date case studies are presented, together with the working, fabrication and design of the sensors.

This open access book offers a host of theoretical knowledge at the basis of new EM&Ts (namely, Interactive Connected Smart Materials, Wearables (ICS), Nanomaterials, Advanced Growing Materials, and Experimental Wood-Based Materials), as communicated through the unique design teaching method developed within the context of the European Project DATEMATS, a result of the creative workshops held by the four higher education institutions that were partners in the project, stressing the pros and cons of the method and offering ideas for further development and improvement. The modern age requires its own innovations in regards to both social and industrial progress, innovations made possible by Emerging Materials and Technologies (EM&Ts). Frameworks for designing both with and for the new materials are presented, educating designers about the opportunities offered by EM&Ts and how to take advantage of them. At the same time, the book explains how the method developed through the knowledge generated at research centers and universities can be communicated to companies across various industries that stand to gain from it, linking the assorted stakeholders, and includes a final chapter based on feedback from both students and business professionals as to the benefits of academic/industrial cooperation. This is an open access book.
Up to 40 volumes are planned for this concise monograph series, which focuses on the implementation of various engineering principles in the conception, design, development, analysis and operation of biomedical, biotechnological and nanotechnology systems and applications. The smartness of nano-materials is attributed to their nanoscale and subsequently unique physicochemical properties and their use in glucose sensing has been aimed at improving performance, reducing cost and miniaturizing the sensor and its associated instrumentation. So far, portable (handheld) glucose analysers were introduced for hospital wards, emergency rooms and physicians' offices; single-use strip systems achieved nanolitre sampling for painless and accurate home glucose monitoring; advanced continuous monitoring devices having 2 to 7 days operating life are in clinical and home use; and continued research efforts are being made to develop and introduce increasingly advanced glucose monitoring systems for health as well as food, biotechnology, cell and tissue culture industries. Nanomaterials have touched every aspect of biosensor design and this chapter reviews their role in the development of advanced technologies for glucose sensing, and especially for diabetes. Research shows that overall, nanomaterials help address the problems with conventional optical and electrochemical biosensors, by enhancing the preferential detection of glucose or its oxidation products through better electron transfer kinetics, sensitivity and response time, while lowering the operating over-voltages for energy efficiency and avoid interference. The reproducible production of nano-materials and nano-structures at low cost is vital for the successful development of nano-technologies for glucose sensing. Several products, especially, home glucose monitoring devices, use nano-materials, but the need for reliable long-term CGM is still unmet. Nano-materials and nano-technologies have an important role in achieving the long-awaited CGM technology.

Even as we enter the nanotechnology era, we are now encountering the 50th anniversary of the invention of the IC. Will silicon continue to be the pre-eminent material and will MooreTM s Law continue unabated, albeit in a broader economic venue, in the nanotechnology era? This monograph addresses these issues by a re-examination of the scientific and technological foundations of the micro-electronics era. By better assessing and understanding the past five decades of this era, it is proposed that a firmer foundation can be laid for the research that will ensue and possibly provide a glimpse of what is next to come in the nanotechnology era."
This tenth volume of papers emanating from the annual International
High Technology Small Firms Conference represents a full decade of
research and policy relevant papers on innovation and growth
problems of New Technology-based Firms (NTBf).
