Book Description
Noble Metals and Biological Systems examines the relationship between noble metals (gold, silver, and platinum group metals) and biological systems. The book is divided into three parts. Part 1 is concerned with the analytical chemistry of noble metals and includes a description of the latest methods of analysis. Part 2 describes such topics as ecology and environmental science of noble metals as they pertain to biogeochemical exploration, noble metals in hair, the environmental geochemistry of palladium, microorganisms and noble metals, animals and noble metals, and a general survey of noble metals in the environment. Coverage is comprehensive and includes information regarding the use of dogs and termites as field assistants in mineral prospecting, as well as the fascinating story of the "gold bug", a microorganism that plates itself with gold. Part 3 is devoted entirely to noble metals in the treatment of disease and includes chapters describing the use of osmium and gold for arthritis treatment, silver as a bactericide, and platinum and ruthenium as anticancer agents. Noble Metals and Biological Systems will provide fascinating reading for applied geochemists, environmentalists, public health specialists, ecologists, microbiologists, clinical biochemists, oncologists, and specialists in rheumatic diseases.

Book Description
Significant refinements of biogeochemical methods applied to mineral exploration have been made during more than twenty years since the last major publication on this technique. This innovative, practical and comprehensive text is designed as a field handbook and an office reference volume. It outlines the historical development of biogeochemical methods applied to mineral exploration, and provides details of what, how, why and when to collect samples from all major climatic environments with examples from around the world. Recent commercialization of sophisticated analytical technology permits immensely more insight into the multi-element composition of plants. In particular, precise determination of ultra-trace levels of 'pathfinder' elements in dry tissues and recognition of element distribution patterns with respect to concealed mineralization. Data handling and interpretation are discussed in context of a wealth of previously unpublished information, including a section on plant mineralogy, much of which has been classified as confidential until recently. Data are provided on the biogeochemistry of more than 60 elements and, by case history examples, their roles discussed in assisting in the discovery of concealed mineral deposits. A look to the future includes the potential role of bacteria to provide new focus for mineral exploration. - Describes the practical aspects of plant selection and collection in different environments around the world, and how to process and analyze them - Discusses more than 60 elements in plants, with data interpretation and case history results that include exploration for Au, PGEs, U, base metals and kimberlites

Book Description
The use of copper, silver, gold and platinum in jewelry as a measure of wealth is well known. This book contains 19 chapters written by international authors on other uses and applications of noble and precious metals (copper, silver, gold, platinum, palladium, iridium, osmium, rhodium, ruthenium, and rhenium). The topics covered include surface-enhanced Raman scattering, quantum dots, synthesis and properties of nanostructures, and its applications in the diverse fields such as high-tech engineering, nanotechnology, catalysis, and biomedical applications. The basis for these applications is their high-free electron concentrations combined with high-temperature stability and corrosion resistance and methods developed for synthesizing nanostructures. Recent developments in all these areas with up-to-date references are emphasized.

Book Description
In nature, biological organisms produce mineralized tissues such as bone, teeth, diatoms, and shells. Biomineralization is the sophisticated process of production of these inorganic minerals by living organisms. Construction of organic-inorganic hybrid materials with controlled mineralization analogous to those produced by nature has recently received much attention because it can aid in understanding the mechanisms of the biomineralization process and development of biomimetic materials processing. The biomineralization ? processes use aqueous solutions at temperatures below 100 C and no toxic intermediates are produced in these systems. From a serious global en- ronmental problem point of view, the development of processes inspired by biomineralization would offer valuable insights into material science and en- neering to reduce energy consumption and environmental impact. One of the most challenging scienti'c problems is to gain greater insight into the mol- ular interactions occurring at the interface between the inorganic mineral and the macromolecular organic matrix. Model systems are often regarded as a straight-forward experimental approach toward biomimetic crystallization. Hierarchical architectures consisting of small building blocks of inorganic cr- tals are often found in biominerals. Studies of nanocrystal self-organization in solution systems would also be helpful for understanding biomineralization. In these volumes, we focus on construction of organic-inorganic hybrid - terials with controlled mineralization inspired by natural biomineralization. In the'rst volume, thereader will ?nd contributionsproviding abasic scopeof the mineralization process in aqueous solution.

Book Description
The yield of major agricultural crops can be severely decreased due to the inappropriate application of commonly used harmful chemicals. Excessive agrochemicals in field application can negatively affect microbial populations and their diversity, which in turn ultimately affects plant growth. Thus, it is necessary to turn toward more eco-friendly approaches which equally protect crops as well as the desirable microbial populations of complex soil systems. Nanoparticles are considered as potential agents for the production and development of sustainable agriculture. Green synthesis of nanoparticles has gained attention as a useful measure to diminish the harmful effects associated with the old methods of nanoparticle synthesis. Advances in Nanotechnology for Smart Agriculture: Techniques and Applications illustrates the science and practical applications of nanoparticles for sustainable agriculture. Features: Examines the role of nanotechnology in agricultural best practices, including sustainable development, precision farming, and long-term soil health
