Book excerpt: Clean coal technologies that involve limestone for sulfur capture generate lime/limestone products laden with sulfur at various oxidation states. If sulfur is completely stabilized as sulfate, the spend sorbent is ready for commercial utilization as gypsum. However, the presence of reduced sulfur species required additional processing. Thermal oxidation of reduced sulfur can result in undesirable release of SO2. Microbial oxidation might provide an inexpensive and effective alternative. Sorbents laden with reduced forms of sulfur such as sulfide, sulfite, or various polythionate species serve as growth substrates for sulfur-oxidizing bacteria, which have the potential to convert all sulfur to sulfate. This quarter, efforts focused on treating the aqueous phase of a waste sorbent obtained from an inhibited wet scrubbing process. Although two named strains, Thiobacillus neapolitanus ATCC 23639 and ATCC 23641, failed; the isolate TQ1 rapidly oxidized thiosalts, producing sulfate. The Virtis Fermentor arrived, so that experiments with TQ1 have been scaled up to 1.5 liters with temperature, aeration, and pH control.

Book excerpt: Clean coal technologies that involve limestone for in situ sulfur capture generate lime/limestone products laden with sulfur at various oxidation states. If sulfur is completely stabilized as sulfate, the spent sorbent is ready for commercial utilization as gypsum. However, the presence of reduced sulfur species requires additional processing. Thermal oxidation of reduced sulfur frequently results in undesirable release of SO2. Microbial oxidation may provide an inexpensive and effective alternative. Sorbents laden with reduced forms of sulfur such as sulfide or sulfite can serve as growth substrates for sulfur-oxidizing bacteria, which convert all sulfur to sulfate. The goals of this project are to optimize conditions for sulfate generation from sulfide and sulfite on prepared lime/limestone mixtures; to test and optimize the effectiveness of microbial processing on spent sorbents from coal gasification, in-duct sorbent injection, and fluidized bed combustion; and to search for hyperalkalinophilic thiobacilli, which would be effective up to pH 11. We report here progress toward controlling the pH of culture media, and determining the highest pH at which several environmental isolates and named strains could initiate sulfur oxidation.

This quarter work continued with the solid phase of a spent slurry from an inhibited scrubber. The material was primarily CaSO3·1/2H2O. The authors did not detect growth of any bacterial strain in salts medium with the solid phase as the source of sulfur. However, unlike strains of Thiobacillus neapolitanus, the isolate TQ, was not inhibited by the solid phase. Evidence suggests that this organism grows slowly on low concentrations of sulfite.

Book excerpt: Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

This book was released on 2020-04-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

This book was released on 2014-02-01 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mogao Grottoes, a World Heritage Site in northwestern China, are located along the ancient caravan routes—collectively known as the Silk Road—that once linked China with the West. Founded by a Buddhist monk in the late fourth century, Mogao flourished over the following millennium, as monks, local rulers, and travelers commissioned hundreds of cave temples cut into a mile-long rock cliff and adorned them with vibrant murals. More than 490 decorated grottoes remain, containing thousands of sculptures and some 45,000 square meters of wall paintings, making Mogao one of the world’s most significant sites of Buddhist art. In 1997 the Getty Conservation Institute, which had been working with the Dunhuang Academy since 1989, began a case study using the Late–Tang dynasty Cave 85 to develop a methodology that would stabilize the deteriorating wall paintings. This abundantly illustrated volume is the definitive report on the project, which was completed in 2010.
