In this thesis, Andrew Logsdail demonstrates that computational chemistry is a powerful tool in contemporary nanoscience, complementing experimental observations and helping guide future experiments. The aim of this particular PhD is to further our understanding of structural and compositional preferences in gold nanoparticles, as well as the compositional and chemical ordering preferences in bimetallic nanoalloys formed with other noble metals, such as palladium and platinum. Highlights include: calculations of the structural preferences and optical-response of gold nanoparticles and gold-containing nanoalloys; the design and implementation of novel numerical algorithms for the structural characterisation of gold nanoparticles from electron microscopy images; and electronic structure calculations investigating the interaction of gold nanoparticles with graphene and graphite substrates.The results presented here have significant implications for future research on the chemical and physical properties of gold-based nanoparticles and are of interest to many researchers working on experimental and theoretical aspects of nanoscience.

Explore recent progress and developments in atomically precise nanochemistry Chemists have long been motivated to create atomically precise nanoclusters, not only for addressing some fundamental issues that were not possible to tackle with imprecise nanoparticles, but also to provide new opportunities for applications such as catalysis, optics, and biomedicine. In Atomically Precise Nanochemistry, a team of distinguished researchers delivers a state-of-the-art reference for researchers and industry professionals working in the fields of nanoscience and cluster science, in disciplines ranging from chemistry to physics, biology, materials science, and engineering. A variety of different nanoclusters are covered, including metal nanoclusters, semiconductor nanoclusters, metal-oxo systems, large-sized organometallic nano-architectures, carbon clusters, and supramolecular architectures. The book contains not only experimental contributions, but also theoretical insights into the atomic and electronic structures, as well as the catalytic mechanisms. The authors explore synthesis, structure, geometry, bonding, and applications of each type of nanocluster. Perfect for researchers working in nanoscience, nanotechnology, and materials chemistry, Atomically Precise Nanochemistry will also benefit industry professionals in these sectors seeking a practical and up-to-date resource.

Atomic clusters are aggregates of atoms containing a few to several thousand atoms. Due to the small size of these pieces of matter, the properties of atomic clusters in general are different from those of the corresponding material in the macroscopic bulk phase. This monograph presents the main developments of atomic clusters and the current status of the field. The book treats different types of clusters with very different properties: clusters in which the atoms or molecules are tied by weak van der Waals interactions, metallic clusters, clusters of ionic materials, and network clusters made of typical covalent elements. It includes methods of experimental cluster synthesis as well as the structural, electronic, thermodynamic and magnetic properties of clusters, covering both experiments and the theoretical work that has led to our present understanding of the different properties of clusters. The question of assembling nanoclusters to form solids with new properties is also considered. Having an adequate knowledge of the properties of clusters can be of great help to any scientist working with objects of nanometric size. On the other hand, nanoclusters are themselves potentially important in fields like catalysis and nanomedicine.

The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

As nanomaterials and their end products occupy the pinnacle position of consumer markets, it becomes vital to analyze their generation processes. One of the green chemistry principles underlines the need for unusual energy sources to generate them. Utilizing the extreme energy from the collapse of cavitation bubbles, generated by either ultrasound or hydrodynamic forces, for the generation of nanomaterials is a merit to consider in this "Green Chemical Processing Era." A wide range of nanomaterials have been developed in the past decade using cavitation or coupling cavitation with other techniques such as microwave, photochemistry, and electrochemistry, resulting in nanomaterials with unique morphologies, reduced size, narrow size distribution, and innumerous advantages. While a few currently available books deal with the fundamental aspects of cavitation and sonochemistry, this book is devoted specifically to the technologically important nanomaterials obtained by cavitation.

Analytical nanoscience and nanotechnology is a growing topic that is expected to have a great impact in the field of analytical chemistry. Many of the exceptional properties of gold nanoparticles make them suitable for different analytical applications and these applications allow extrapolations for their use in other fields as well. In analytical chemistry gold nanoparticles play two main roles, namely: i) As target analytes in the realm of the analysis of the nanoworld; and ii) As tools to improve analytical processes, such as the use of gold nanoparticles as components of electrodes, in spectroscopic techniques and (bio)chemical sensors and lateral flow sensors. This book is a comprehensive review of the role of gold nanoparticles in analytical nanoscience and nanotechnology, with chapters devoted to their synthesis, physico-chemical characteristics, derivatization and potential toxicity. The main microscopic, spectroscopic and separation techniques for the characterization are reviewed as well as the developments for their determination in environmental, biological and agrifood samples. - Provides an integral approach devoted to a specific nanoparticle - Considers gold nanoparticles as target analytes, as analytical tools and their relationships - Organizes the material in a novel way
