Download or read book Catalysis By Gold written by Geoffrey C Bond and published by World Scientific. This book was released on 2006-08-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered./a

Available in PDF, EPUB and Kindle. Book excerpt: The Report on Carcinogens (RoC) is a congressionally mandated, science-based, public health document that identifies and discusses agents, substances, mixtures, or exposure circumstances (hereinafter referred to as "substances") that may pose a hazard to human health by virtue of their carcinogenicity. For each listed substance, the report contains a substance profile which provides information on (1) the listing status, (2) cancer studies in humans and animals, (3) studies of genotoxicity (ability to damage genes) and biologic mechanisms, (4) the potential for human exposure to these substances, and (5) Federalregulations to limit exposures. Eight substances have been added to this 12th ed. of the report, which now includes 240 listings. The industrial chemical formaldehyde and a botanical known as aristolochic acids are listed as known human carcinogens. Six other substances captafol, cobalt-tungsten carbide (in powder or hard metal form), certain inhalable glass wool fibers, o-nitrotoluene, riddelliine, and styrene are added as substances that are reasonably anticipated to be human carcinogens. Figures. This is a print on demand report.

Download or read book Development of a Zero headspace Aerobic Suspended Growth Bioreactor written by and published by . This book was released on 1994 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense has over 12,000 sites that are contaminated from past military activities. Many site contain volatile organic contaminants that may be treated using aboveground or in situ aerobic biotreatment systems. Three oxygen sources for activated sludge were evaluated using 3-L chemostats treating amended groundwater containing over 200 mg/l benzene. The oxygen sources were compared based on percent contaminant removal, reduction of benzene off-gassing, and biomass stability. The fate of hydrogen peroxide in an activated sludge system was evaluated and described using an equation that determines steady-state hydrogen peroxide concentration. The equation is essentially a simple fate model that includes input, output, and both biotic and abiotic terms. The results indicated that peroxide could be used as an alternative oxygen source with no release of benzene into the ambient air; however, this approach was found to be expensive because of the high cost of hydrogen peroxide. Benzene was removed from the groundwater to below detection levels. Pure oxygen sparging was a particularly attractive means of introducing oxygen with minimal stripping of benzene. Biotic reactions dominated hydrogen peroxide fate within an activated sludge system. The reaction between hydrogen peroxide and biomass was second order overall and first order with respect to both reactants.

Download or read book Van Nostrand s Scientific Encyclopedia written by Douglas M. Considine and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 3529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advancements in science and engineering have occurred at a surprisingly rapid pace since the release of the seventh edition of this encyclopedia. Large portions of the reference have required comprehensive rewriting and new illustrations. Scores of new topics have been included to create this thoroughly updated eighth edition. The appearance of this new edition in 1994 marks the continuation of a tradition commenced well over a half-century ago in 1938 Van Nostrand's Scientific Encyclopedia, First Edition, was published and welcomed by educators worldwide at a time when what we know today as modern science was just getting underway. The early encyclopedia was well received by students and educators alike during a critical time span when science became established as a major factor in shaping the progress and economy of individual nations and at the global level. A vital need existed for a permanent science reference that could be updated periodically and made conveniently available to audiences that numbered in the millions. The pioneering VNSE met these criteria and continues today as a reliable technical information source for making private and public decisions that present a backdrop of technical alternatives.
