Metallic nanoparticles display fascinating properties that are quite different from those of individual atoms, surfaces or bulk rmaterials. They are a focus of interest for fundamental science and, because of their huge potential in nanotechnology, they are the subject of intense research effort in a range of disciplines. Applications, or potential applications, are diverse and interdisciplinary. They include, for example, use in biochemistry, in catalysis and as chemical and biological sensors, as systems for nanoelectronics and nanostructured magnetism (e.g. data storage devices), where the drive for further miniaturization provides tremendous technological challenges and, in medicine, there is interest in their potential as agents for drug delivery. The book describes the structure of metallic nanoparticles, the experimental and theoretical techniques by which this is determined, and the models employed to facilitate understanding. The various methods for the production of nanoparticles are outlined. It surveys the properties of clusters and the methods of characterisation, such as photoionization, optical spectroscopy, chemical reactivity and magnetic behaviour, and discusses element-specific information that can be extracted by synchrotron-based techniques such as EXAFS, XMCD and XMLD. The properties of clusters can vary depending on whether they are free, deposited on a surface or embedded in a matrix of another material; these issues are explored. Clusters on a surface can be formed by the diffusion and aggregation of atoms; ways of modelling these processes are described. Finally we look at nanotechnology and examine the science behind the potential of metallic nanoparticles in chemical synthesis, catalysis, the magnetic separation of biomolecules, the detection of DNA, the controlled release of molecules and their relevance to data storage. The book addresses a wide audience. There was a huge development of the subject beginning in the mid-1980s where researchers began to study the properties of free nanoparticle and models were developed to describe the observations. The newcomer is introduced to the established models and techniques of the field without the need to refer to other sources to make the material accessible. It then takes the reader through to the latest research and provides a comprehensive list of references for those who wish to pursue particular aspects in more detail. It will also be an invaluable handbook for the expert in a particular aspect of nanoscale research who wishes to acquire knowledge of other areas. The authors are specialists in different aspects of the subject with expertise in physics and chemistry, experimental techniques and computational modelling, and in interdisciplinary research. They have collaborated in research. They have also collaborated in writing this book, with the aim from the outset of making it is a coherent whole rather than a series of independent loosely connected articles. * Appeals to a wide audience * Provides an introduction to established models and techniques in the field * Comprehensive list of references

The field of nanoscience has undergone tremendous growth in the past decade as the number of applications of nanoparticles and nanostructured materials have proliferated. Metal nanoparticles have attracted particular interest due to their potential for applications in areas as diverse as catalysis, medicine and opto-electronics. The chemical and physical properties of metal nanoparticles can vary smoothly or discontinuously with nanoparticle size, depending on the size regime and the property. In the case of bi- or multimetallic nanoparticles ("nanoalloys"), these properties also depend on the elemental composition and the chemical ordering – how the metals are distributed in the nanoparticles.It is this tunability of behavior that makes metal nanoparticles and nanoalloys so versatile and appealing. This book begins with a tutorial introducing the theoretical ideas and models that have been developed to understand metal nanoparticles. It gives an overview of experimental methods for generating and characterizing metal nanoparticles and nanoalloys and of their properties and applications, providing an introduction to material covered in more depth in subsequent chapters. A major theme of all the chapters is the effect of nanoparticle size, shape and surface chemistry on their properties – especially optical and catalytic properties. A unified discussion of the inter-relations between modelling, synthesis and physical properties of nanoparticles and nanoalloys A discussion of the most promising new catalytic and photocatalytic applications of nanoparticles and the approaches used to achieve these goals A tutorial introduction which provides a basis for understanding the subsequent specialized chapters

This book introduces the fascinating world of plasmonics and physics at the nanoscale, with a focus on simulations and the theoretical aspects of optics and nanotechnology. A research field with numerous applications, plasmonics bridges the gap between the micrometer length scale of light and the secrets of the nanoworld. This is achieved by binding light to charge density oscillations of metallic nanostructures, so-called surface plasmons, which allow electromagnetic radiation to be focussed down to spots as small as a few nanometers. The book is a snapshot of recent and ongoing research and at the same time outlines our present understanding of the optical properties of metallic nanoparticles, ranging from the tunability of plasmonic resonances to the ultrafast dynamics of light-matter interaction. Beginning with a gentle introduction that highlights the basics of plasmonic interactions and plasmon imaging, the author then presents a suitable theoretical framework for the description of metallic nanostructures. This model based on this framework is first solved analytically for simple systems, and subsequently through numerical simulations for more general cases where, for example, surface roughness, nonlinear and nonlocal effects or metamaterials are investigated.

Metal nanoparticles are certainly the building block of the next generation of electronic, optoelectronic and chemical sensing devices. The emerging themes in nanoparticle research are synthesis and assembly of nanoparticles, variations in the size and shape, and surface chemistry effects on particle properties. For synthesizing metallic nanoparticles, various synthesis methods have been used. Here we have reported three different methods for the synthesis of nanoparticles 1) by using dendrimers molecules, 2) using microemulsions and, 3) direct reduction of metallic salt. Iron, gold and copper nanoparticles were synthesized using above mentioned methods. Appropriate reactant concentrations and conditions were determined for the synthesis of iron nanoparticles. Detailed discussion of advantages and disadvantages for synthesizing metallic nanoparticles with these methods has been reported. Among known applications of metallic nanoparticles, production of hydrogen by reacting metal nanoparticles with water have been studied under optimal reaction conditions. These reactions are safe, low-cost, convenient, and environmental-benign along with enhanced reaction kinetics due to high reactivity of particles. Various metals are known for storing hydrogen using different phenomenas. Here we described a new system consisting of metallic nanoparticles submerged in oil. This system can be effectively used for storing hydrogen and possess many advantages over the traditional systems, though it needs to be verified experimentally.

In recent years, research has focused on reducing the cost of catalysts in a variety of ways including using less expensive materials, improving the synthetic method, and increasing the catalytic activity, recovery, and recyclability. Typically with nanoparticles, the size, shape, composition, and surface coating have an effect on catalytic activity. 1−2 In this work, we focused on reducing the cost of precious metal based catalysts by altering the synthetic methods. One way to lower the cost of synthesizing precious metal nanoparticles is by debasing the precious metal with a second cheaper more abundant metal. CuPd nanoparticles were synthesized in oleylamine and displayed catalytic activity in several cross-coupling reactions. Due to copper being present in the nanoparticle, a copper halide co-catalyst was not needed for Sonogashira cross coupling to be successful. 3 While this method produced reactive catalysts, low product yield hinders its application for industry. Solution based synthesis of metallic nanoparticles typically require long reaction times and high temperatures, which make large scale production of nanoparticles on an industrial scale difficult.4−5The use of continuous flow microreactors provides greater control of synthetic parameters, leading to lower batch-to-batch variability and increasing the efficient of heat and mass transfer and have been applied to the synthesis of metals, semiconductors, zeolites, organic compounds, and semiconductors.5−7 To compare continuous flow methods to benchtop reactions, a well-characterized benchtop reaction synthesizing Cu@Ni core/shell nanoparticles was successfully transferred to a flow reactor set-up. Cu@Ni nanoparticles were synthesized using a capillary microreactor in under 1 minute compared to the 1 hour reaction on benchtop with similar properties in a green solvent.2 The Cu@Ni nanocomposites were active towards the Fischer Tropsch reaction. 8 2 nm platinum nanoparticles and platinum bimetallic alloys were synthesized in water using a capillary microwave flow reactor. Investigations showed the nanoparticles were activity toward hydrogenation of octene. With further development, continuous flow synthesis of metallic nanoparticles can be applied to the synthesis of a wide variety of catalysts on an industrial scale. Continuous flow methods provide greater control of reaction parameters, increased safety by reacting smaller volumes of chemicals at a given time, and decreasing the batch-to-batch variability.

Metal nanoparticles that have already found numerous applications in science and technology may be obtained in different ways. In the opening study included in Metal Nanoparticles: Properties, Synthesis and Applications, several factors affecting metal nanoparticle morphology in island films are determined. The formation of islet metal films during their deposition in the process of thermal evaporation on a dielectric substrate and their spontaneous changes at room temperature are also described. Following this, the authors present their experimental results on synthesis, modification and destruction of silver nanoparticles in the bulk and surface of silicate glasses. Special attention is paid to the effects of laser and electron-beam irradiation on the above-mentioned processes. The authors go on to review the synthesis of embedded noble metal nanoparticles and their optical properties and potential applications in surface enhanced Raman scattering. The optical properties of NMNPs due to the localized surface plasmon resonance and the enhanced local electromagnetic field which govern their SERS activity will be discussed along with their fundamental mechanisms. The effects of zinc, titanium, copper and oxide thin films with nanostructured surfaces and iron oxide and silver nanoparticles on Enterococcus hirae and Escherichia coli growth and membrane activity are also presented and discussed. The authors suggest that different types of metal nanoparticles could be applied in medicine due to their antimicrobial activity, effeciency in anti-inflammatory effects and potential in anticancer therapy. Next, the development of platinum-metal nanoparticles and their core-shell structures is discussed. The authors analyze in detail the polymeric composite of the metal nanoparticles on the surface of different carbon support materials (e.g. carbon nanotubes, graphene, carbon-nanospheres, mesoporous carbon, and carbon nanofibers), showing the synergetic effects on the active surface area of platinum metal catalysts. In one review, the past decade's data regarding the effects of nanoparticles of noble metals on higher plants are considered, as well as possible nanoparticle phytotoxicity. The review discusses the various effects that gold and silver nanoparticles can have on the state, growth, and productivity of plants. Published evidence, although incomplete and contradictory, indicates that metal nanoparticles can have both positive and negative effects on plants. Lastly, glassy carbon electrodes modified with polyphenazine conducting polymers and metallic nanoparticles were used to study the interaction between H2O2 and ascorbic acid. The antioxidant capacity of ascorbic acid measured from this interaction agreed with that reported using non-electrochemical techniques.
