English | Nov 1995 | ISBN: 3527292071 | 480 Pages | PDF | 35 MB
Reactions with metals are ubiquitous in organic synthesis and, particularly in the last few years, a large repertoire of methods for the activation of metals and for their use in organic synthesis has been developed.

Active Metals: Preparation*Characterization*Applications by Alois Frstner
In Active Metals, topics ranging from morphology of metal clusters and nanometallurgy to organometallic chemistry, catalysis and the use of activated metals in natural product synthesis are authoritatively discussed by leading experts in the field.

Ecotoxicology of Amphibians and Reptiles, Second Edition by Greg Linder

Ecotoxicology of Amphibians and Reptiles, Second Edition by Greg Linder
Building on the success of its popular predecessor, the second edition of Ecotoxicology of Amphibians and Reptiles presents newly available findings on the species that are important environmental indicators. This new edition covers nearly twice as many topics as the first, including recent developments in the ecotoxicology of amphibians and reptiles, the current status of these animals, and intrinsic factors that affect their susceptibility to contaminants. The book also provides the latest information on specific groups of contaminants and their effects and body burdens in herpetafauna. After a review of how contaminants interact with other ecological factors, the text explores concerns for the future.

New in the second edition:

– New research on the effects of pesticides, heavy metals, endocrine disrupting chemicals, and UVB
– Increased focus on the effects of contaminants rather than merely reporting residue information
– A synthesis of information on atrazine and its effects on gonads at low concentrations
– Coverage of the potentially alarming new cadre of chemicals that have recently or are about to come on the market for which there is very little or no information
– Important advances in surveying and monitoring

One of the major factors behind the writing of the first edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. With chapter contributors carefully selected by the team of editors as leaders in their fields, this book provides an authoritative compendium of the most recent information on effects and residues coupled with a syntheses of what these numbers mean to science and policy.

Non-Renewable Resource Issues: Geoscientific and Societal Challenges

Non-Renewable Resource Issues: Geoscientific and Societal Challenges (International Year of Planet Earth) by Richard Sinding-Larsen and Friedrich-W. Wellmer
English | ISBN: 9048186781 | 2012 | 270 pages | PDF | 6,9 MB

Non-Renewable Resource Issues: Geoscientific and Societal Challenges
All the solid fuels fossil energy and mineral commodities we use come out of the Earth. Modern society is increasingly dependent on mineral and fossil energy sources. They differ in availability, cost of production, and geographical distribution. Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secondary resources and their use increases, the world still needs and will continue to need primary mineral resources for the foreseeable future. Growing demands have begun to restrict availability of these resources. The Earth is not running out of critical mineral resources – at least for the near future – but the ability to explore and extract these resources is being restricted in many regions by competing land use, as well as political and environmental issues. Extraction of natural resources requires a clear focus on sustainable development, involving economic, environmental and socio-cultural aspects. Although we do not know what the most important resources will be in 100 years from now, we can be quite certain that society will still need energy and a wide range of raw materials. These resources will include oil and gas, coal, uranium, thorium, geothermal, metallic minerals, industrial and specialty minerals, including cement, raw materials, rare-earth elements. A global approach for assessing the magnitude and future availability of these resources is called for – an approach that, with appropriate international collaboration, was started within the triennium of the International Year of Planet Earth. Some global mineral resource assessments, involving inter-governmental collaboration, have already been initiated. The International Year of Planet Earth helped to focus attention on how the geosciences can generate prosperity locally and globally, as well as sustainability issues in both developed and developing countries.

Hydrogen Safety (Green Chemistry and Chemical Engineering)

Hydrogen Safety (Green Chemistry and Chemical Engineering) by Fotis Rigas and Paul Amyotte
English | 2012 | ISBN: 1439862311 | 304 pages | PDF | 19 MB
Hydrogen Safety highlights physiological, physical, and chemical hazards associated with hydrogen production, storage, distribution, and use systems. It also examines potential accident scenarios that could occur with hydrogen use under certain conditions.

Hydrogen Safety (Green Chemistry and Chemical Engineering)
The number of potential applications for hydrogen continues to grow-from cooling power station generators to widespread commercial use in hydrogen fuel-cell vehicles and other fuel-cell applications. However, this volatile substance poses unique challenges, including easy leakage, low ignition energy, a wide range of combustible fuel-air mixtures, buoyancy, and its ability to embrittle metals that are required to ensure safe operation.
Focused on providing a balanced view of hydrogen safety-one that integrates principles from physical sciences, engineering, management, and social sciences-this book is organized to address questions associated with the hazards of hydrogen and the ensuing risk associated with its industrial and public use.
* What are the properties of hydrogen that can render it a hazardous substance?
* How have these hazards historically resulted in undesired incidents?
* How might these hazards arise in the storage of hydrogen and with its use in vehicular transportation?
The authors address issues of inherently safer design, safety management systems, and safety culture. They highlight hydrogen storage facilities -which pose greater hazards because of the increased quantities stored and handled-and the dangers of using hydrogen as a fuel for transport. Presented experiments are included to verify computer simulations with the aid of computational fluid dynamics (CFD) of both gaseous and liquefied hydrogen. The book also provides an overview of the European Commission (EC) Network of Excellence for Hydrogen Safety (HySafe) and presents various case studies associated with hydrogen and constructional materials. It concludes with a brief look at future research requirements and current legal requirements for hydrogen safety.
