Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Computational Study of Small Gold Clusters H2S Thiols H2O and Alcohols written by Silvija C. Smith and published by . This book was released on 2014 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulk gold is known to be one of the least reactive metals. In contrast, gold colloids and gold nanoclusters exhibit unique chemical and physical properties, due to their stability, uniformity, and size related characteristics. These interesting attributes cause gold nanoclusters to have promising applications in catalysis, biosensors, and optoelectronics. In particular, many of the applications for gold nanoclusters are in the fields of biomedicine and biotechnology. These potential applications require aggregation resistant, water-soluble nanoparticles capable of withstanding an environment within living organisms. Additionally, previous studies have shown that supported gold nanoclusters can be used as catalysts for many hydrogenation and oxidation reactions at low temperatures. These reactions include the oxidation of carbon monoxide (CO) and nitric oxide (NO), partial oxidation of propylene, and partial and complete hydrogenation of acetylene and ethylene, respectively. In this thesis, density functional theory (DFT) calculations are used to obtain energies of equilibrium structures from geometry optimizations and vibrational frequencies of small gold clusters, with one to four gold atoms bonded to a water molecule, small alcohols, or short-chain thiols, SHR, wth R=H, CH 3, CH3 CH2 . Additionally, density functional theory, Moller-Plesset Perturbation theory, and coupled cluster theory calculations were used to obtain energies, optimal geometries, vibrational frequencies, activation energies, and the rate of reaction for the hydrogen atom transfer from sulphur to gold of the RSH-Au n and RSAun H complexes. These complexes consist of small gold clusters, with n=1-4 and short-chain thiols wth R=H, CH3, and CH3 CH2. The Gibbs free energies were calculated to determine whether the hydrogen atom transfer occurs as a thermodynamically spontaneous reaction. Additionally, common trends of the cluster complexes including bond lengths and characteristic gold-sulphur and gold-oxygen vibrational stretching were examined. Depending on the ligand attached to the gold cluster and the overall charge of the complex, bridge-bonding to different pairs of gold atoms in the cluster can occur with the hydrogen atom that has been transferred and the sulphur atom or oxygen atom. These theoretical studies are used to expand on the limited understanding of gold clusters and their interesting characteristics. Additionally, these studies determine the versatility of various basis functionals and basis sets when used on many electron atoms, such as gold. The results from this study are compared to similar studies involving gold clusters.

Download or read book Gold Nanoparticles in Biomedical Applications written by Lev Dykman and published by CRC Press. This book was released on 2017-12-12 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses fabrication of functionalized gold nanoparticles (GNPs) and multifunctional nanocomposites, their optical properties, and applications in biological studies. This is the very first book of its kind to comprehensively discuss published data on in vitro and in vivo biodistribution, toxicity, and uptake of GNP by mammalian cells providing a systematization of data over the GNP types and parameters, their surface functionalization, animal and cell models. As distinct from other related books, Gold Nanoparticles in Biomedical Applications discusses the immunological properties of GNPs and summarizes their applications as an antigen carrier and adjuvant in immunization for the preparation of antibodies in vivo. Although the potential of GNPs in nanobiotechnology has been recognized for the past decade, new insights into the unique properties of multifunctional nanostructures have recently emerged. With these developments in mind, this book unites ground breaking experimental data with a discussion of hybrid nanoparticle systems that combine different nanomaterials to create multifunctional structures. These novel hybrids constitute the material basis of theranostics, bringing together the advanced properties of functionalized GNPs and composites into a single multifunctional nanostructure with simultaneous diagnostic and therapeutic functions. Such nanohybrids can be physically and chemically tailored for a particular organ, disease, and patient thus making personalized medicine available.

Download or read book Update on Gold Nanoparticles written by Valerio Voliani and published by Smithers Rapra. This book was released on 2013-01-29 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, gold nanoparticles have provided a suitable platform for the development of novel and efficient diagnostic and therapeutic tools, which avoid the typical drawbacks of the old systems. They are biocompatible and they can be easily synthesised, encapsulated and functionalised with (bio)molecules. Nanoparticles produced by a wet chemistry synthesis have the geometry, which enables the complete control of their optical and physical properties. It is also possible to influence the targeting and stability/release behaviour by coating the nanoparticle surface. In this Update the reader can find in a single volume the methods used most often for the synthesis and coating of gold nanoparticles (spheres, cages, cubes, rods), the links between optical features and geometries of gold nanoparticles, and the novel applications in nanomedicine of gold nanoparticles determined by their geometry. One of the main objectives of this Update is to provide, a readily comprehensible connection in all the chapters between the geometry of gold nanoparticles and their final applications. Another target of this book is to provide information about efficient processes for the synthesis and the coating of gold nanoparticles, all of which have been directly tested by the author. This Update offers comprehensive information on the whole topic from the synthesis of the gold nanoparticles to their medical applications; this is accompanied by a complete and recent bibliography, in order to give to the readers the opportunity to research further the topics addressed in the book. In this way, students and researchers from academia and industry can have a complete picture of gold nanostructures, physicians and biologists can develop ideas and applications for the new nano-tools, and chemists can have a general guide to the synthesis of gold nanoparticles. This is a state-of-the-art guide for the synthesis and uses of gold nanoparticles.

Download or read book Brownian Dynamics Study of the Self assembly of Ligated Gold Nanoparticles and Other Colloidal Systems written by Siddique J. Khan and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We carry out Brownian Dynamics Simulations to study the self-assembly of ligated gold nanoparticles for various ligand chain lengths. First, we develop a phenomenological model for an effective nanoparticle-nanoparticle pair potential by treating the ligands as flexible polymer chains. Besides van der Waals interactions, we incorporate both the free energy of mixing and elastic contributions from compression of the ligands in our effective pair potentials. The separation of the nanoparticles at the potential minimum compares well with experimental results of gold nanoparticle superlattice constants for various ligand lengths. Next, we use the calculated pair potentials as input to Brownian dynamics simulations for studying the formation of nanoparticle assembly in three dimensions. For dodecanethiol ligated nanoparticles in toluene, our model gives a relatively shallower well depth and the clusters formed after a temperature quench are compact in morphology. Simulation results for the kinetics of cluster growth in this case are compared with phase separations in binary mixtures. For decanethiol ligated nanoparticles, the model well depth is found to be deeper, and simulations show hybrid, fractal-like morphology for the clusters. Cluster morphology in this case shows a compact structure at short length scales and a fractal structure at large length scales. Growth kinetics for this deeper potential depth is compared with the diffusion-limited cluster-cluster aggregation (DLCA) model. We also did simulation studies of nanoparticle supercluster (NPSC) nucleation from a temperature quenched system. Induction periods are observed with times that yield a reasonable supercluster interfacial tension via classical nucleation theory (CNT). However, only the largest pre-nucleating clusters are dense and the cluster size can occasionally range greater than the critical size in the pre-nucleation regime until a cluster with low enough energy occurs, then nucleation ensues. Late in the nucleation process the clusters display a crystalline structure that is a random mix of fcc and hcp lattices and indistinguishable from a randomized icosahedra structure. Next, we present results from detailed three-dimensional Brownian dynamics simulations of the self-assembly process in quenched short-range attractive colloids. Clusters obtained in the simulations range from dense faceted crystals to fractal aggregates which show ramified morphology on large length scales but close-packed crystalline morphology on short length scales. For low volume fractions of the colloids, the morphology and crystal structure of a nucleating cluster are studied at various times after the quench. As the volume fraction of the colloids is increased, growth of clusters is controlled by cluster diffusion and cluster-cluster interactions. For shallower quenches and low volume fractions, clusters are compact and the growth-law exponent agrees well with BinderStauffer predictions and with recent experimental results. As the volume fraction is increased, clusters do not completely coalesce when they meet each other and the kinetics crosses over to diffusion-limited cluster-cluster aggregation (DLCA) limit. For deeper quenches, clusters are fractals even at low volume fractions and the growth kinetics asymptotically reaches the irreversible DLCA case.
