    Note: Focuses on the synthesis of porous solids and introduces nanocasting from fundamental principles to their use in the synthesis of various materials, Nanostructured materials with tailored properties are regarded as a fundamental element in the development of future science and technology. Research is still ongoing into the nanosized construction elements required to create functional solids. The recently developed technique, nanocasting, has great advantage over others in terms of the synthesis of special nanostructured materials by the careful choice of suitable elements and nanoengineering steps. This new book summarizes the recent developments in nanocasting, including the principles of nanocasting, syntheses of novel nanostructured materials, characterization methods, detailed synthetic recipes and further possible development in this area. The book focuses on the synthesis of porous solids from the viewpoint of methodology and introduces the science of nanocasting from fundamental principles to their use in synthesis of various materials. It starts by outlining the principles of nanocasting, requirements to the templates and precursors and the tools needed to probe matter at the nanoscale level. It describes how to synthesize nano structured porous solids with defined characteristics and finally discusses the functionalization and application of porous solids. Special attention is given to new developments in this field and future perspectives. A useful appendix covering the detailed synthetic recipes of various templates including porous silica, porous carbon and colloidal spheres is included which will be invaluable to researchers wanting to follow and reproduce nanocast materials.

    Note: This new publication brings together contemporary approaches for designing nanostructures that employ naturally derived self-assembling motifs as synthetic platforms, The progress of today's science and technology encounters an increasing demand for finer and more efficiently performing materials with properties superior over those of current and hence ageing devices. Whether this is concerned with electronics or drug delivery, cancer diagnostics or alternative energy sources, the search for means of miniaturizing the existing materials or devising fundamentally new components with higher capacities appears to be relentless. A saving solution to this is widely proposed as the design and fabrication of nanostructures, molecular architectures with dimensions featured below 100 nm. Replicating Nature's designs faithfully reproduced over millions of years provides perhaps the most straightforward route to success. Nature offers examples of nanodefined self-assemblies in virtually all levels of biological organization. However explicit guidance to the fabrication of functional or specialist nanostructures is of paramount importance. Nanotechnology is often referred to as building nanoscale structures from bottom up. However, while it is visually clear what is at "up" little is given and understood what is at the "bottom". This new book gives the notion of and provides rules for building nanostructures from basics - the very bottom. The main objective of this publication is to bring together contemporary approaches for designing nanostructures that employ naturally derived self-assembling motifs as synthetic platforms. The book has been written to satisfy the demands that motivate the search for and principles that prove to help the design of novel nanostructures. The overall goal is to compile the existing understanding of rules that govern biomolecular self-assembly ++ , into a practical guide to molecular nanotechnology. It is written in the shape of a review referenced as fully as permissible within the context of biomolecular design, which forms a general trend throughout. The volume is composed of three core chapters focusing on three prominent topics of applied nanotechnology where the role of nanodesign is predominant. The three key areas from which popular highlights can be drawn are: -employing the genetic repository, DNA, for creating various geometric nanoscale objects and patterns -the empirical pursuit of an artificial virus, a magic bullet in gene therapy -designing artificial extracellular matrices for regenerative medicine Specific applications that arise from designed nanoscale assemblies as well as fabrication and characterization techniques are of secondary importance and whenever they appear serve as progress and innovation highlights. The book takes an unconventional approach in delivering material of this kind. It does not lead straight to applications or methods as most nanotechnology works tend to do, but instead it focuses on the initial and primary aspect of "nano" rather than on "technology". Nanodesign is unique in its own field - illustrations are essential and the cohort of brilliant bioinspired designs reported to date form a major part of the publication. In addition, key bibliographic references are covered as fully as possible. A special appendix giving a short list of leading world laboratories engaged in bioinspired nanodesign is also included

    Note: The first book on bioactive nanoceramics to unite the many multidisciplinary concepts useful for those working in bioceramics today, Recent developments in nanostructured materials have led to a shift in focus away from the replacement of tissues and towards regeneration. Nanoceramics with biomimetic properties have great potential in bone regeneration and new synthesis strategies have been developed to obtain materials with improved biocompatibility and multifunctional performance. The aim is to develop fully biocompatible implants, which exhibit biological responses at the nanometric scale in the same way that biogenic materials do. Current man-made implants are not fully biocompatible and always result in a foreign body reaction involving inflammatory response and fibrous encapsulation. Great efforts have, therefore, been made to develop synthetic strategies that tailor implant surfaces at the nanometric scale. The intention is to optimize the interaction at the tissue/implant interface thus improving quality of life for patients with enhanced results and shorter rehabilitation periods. This book deals with 'new bioceramics' for 'new applications'. Current and future applications are considered in terms of chemical composition, structure and properties. It explains the processes that (from the point of view of solid state and sol-gel chemistry) lead to better bone implants and other medical devices. The book is structured to make it useful for students of biomaterials, but also as a reference for specialists interested in specific topics. Didactic figures and schemes make it easy for under-graduates to understand and the extended bibliography is indispensable for researchers. The introductions to each chapter deal with some common fundamental concepts thus allowing the comprehension of each one independently. The first chapter describes biological hard tissues ++ , in vertebrates, from the point of view of mineralization processes. Concepts of hard tissue mineralization are employed to explain how nature works and an overview of artificial alternatives is provided. Chapter 2 details several synthesis methodologies used to prepare nano-apatites. The aim is to obtain artificial carbonated calcium deficient nano-apatites that resemble, as closely as possible, natural biological apatites. A review on synthesis methods is collected in the bibliography. Chapter 3 describes, in-depth, the biomimetic processes used to prepare apatites similar to biological ones. It focuses on hard tissue-related biomimetism and deals with nanoceramics obtained as a consequence of biomimetic processes. Valuable information about the most widely used biomimetic solutions and evaluation methods are included. The final chapter provides an overview of the current and potential clinical applications of apatite-like biomimetic nanoceramics, intended as biomaterials for hard tissue repair, therapy and diagnosis

    Note: Accessible in style, Nanofluidics fills a gap in the literature for a book focusing on bioanalytical applications within this growing field, In his now celebrated lecture at the 1959 meeting of the American Physical Society, Richard Feynman pondered the potential of miniaturization in the physical sciences. His vision, based on known technology, examined the limits set by physical principles and proposed a variety of new nano-tools including the concept of "atom-by-atom" fabrication. In the intervening decades, many of these predictions have become reality. In particular, the development and application of nanofluidics is becoming a competitive and exciting field of research. These nanoscale analytical instruments employ micromachined features and are able to manipulate fluid samples with high precision and efficiency. In a fundamental sense, chip-based analytical systems have been shown to have many advantages over their conventional (larger) analogues. Despite the growth of this field, there are surprisingly few books dedicated to nanofluidics. This book will fill the gap in the literature for a text focusing on bioanalytical applications. Written at a level accessible to experts and non-experts alike, it has the potential to become a mainstream text book for advanced nanobiotechnology courses within academic institutions

    Note: This book offers a unique perspective of the impact of scanning probe microscopies on our understanding of the surface chemistry at the nanoscale, This book offers a unique perspective of the impact of scanning probe microscopes on our understanding of the chemistry of the surface at the nanoscale. Research oriented, with the concepts gleaned from Scanning Tunnelling Microscopy being related to the more established and accepted views in surface chemistry and catalysis, the authors have addressed the question "How do the models based on classical spectroscopic and kinetic studies stand up to scrutiny at the atom-resolved level?". In taking this approach the reader, new to the field of surface chemistry, should be able to obtain a perspective on how the evidence from STM confirms or questions long standing tenets. An emphasis is given to "how did we get to where we are now" and a large number of figures from the literature are included along with suggestions for further reading. Topics discussed include: - the dynamics of oxygen chemisorption at metal surfaces - control of oxygen states and surface reconstruction - dissociative chemisorption of diatomic and hydrocarbon molecules - nanoparticles and chemical reactivity - STM at high pressures - structural studies of sulfur containing molecules and molecular templating This book will appeal to all those who wish to become familiar with the contribution Scanning Tunnelling Microscopy has made to the understanding of the field of surface chemistry and heterogeneous catalysis and also to those who are new to catalysis, a fascinating and important area of chemistry

    Content: OECD indicators of structural policy show that policy changes in Italy since 1998 should have improved the environment for entrepreneurship significantly, but in the same period its economic performance has deteriorated noticeably. This may be partly because there is a difference between policy measures intended by the government or parliament and their impact on the business environment perceived by entrepreneurs. There is no certainty as to what are the main culprits, but a number of policy steps would help to improve the situation. These include better thought out and better written legislation and implementing regulations, more use of performance-oriented management in public administration, and further streamlining and reduction of incentives to procrastination in the judicial system. Legislative simplification and transparency will increase economic efficiency in themselves, while also making a contribution to reducing the incentives and opportunities for corruption and organised crime to flourish. Clear operational independence with accountability is essential for bodies monitoring and assessing the extent of corruption. This Working Paper relates to the 2013 OECD Economic Survey of Italy (www.oecd.org/eco/surveys/Italy).

    Content: In Norway house prices have risen to high levels, associated with very strong credit growth, in a context of low interest rates. Such a combination was in many countries a contributory factor to the 2008- 09 crisis. The Norwegian authorities have been well aware of the problem. Below-target inflation and low interest rates abroad have kept policy interest rates low. “Macro-prudential” tools have been developed as additional policy instruments with a view to strengthen the banking system’s resilience to possible shocks and dampen systemic risk. This chapter notes that although authorities seem to have succeeded in containing over-heating pressures in the housing market, high levels of household indebtedness persist, a phenomenon which was an important factor in the last major Norwegian recession. The chapter also provides some longer run considerations on resource allocation in the housing market. This Working Paper relates to the 2014 OECD Economic Survey of Norway (www.oecd.org/eco/surveys/economic-survey-norway.htm).
