Nitrogen Capture: The Growth Of An International Industry (1900-1940)

by Anthony S. Travis

This monograph provides an account of how the synthetic nitrogen industry became the forerunner of the 20th-century chemical industry in Europe, the United States and Asia. Based on an earlier SpringerBrief by the same author, which focused on the period of World War I, it expands considerably on the international aspects of the development of the synthetic nitrogen industry in the decade and a half following the war, including the new technologies that rivalled the Haber-Bosch ammonia process. Travis describes the tremendous global impact of fixed nitrogen (as calcium cyanamide and ammonia), including the perceived strategic need for nitrogen (mainly for munitions), and, increasingly, its role in increasing crop yields, including in Italy under Mussolini, and in the Soviet Union under Stalin. The author also reviews the situation in Imperial Japan, including the earliest adoption of the Italian Casale ammonia process, from 1923, and the role of fixed nitrogen in the industrialization of colonial Korea from the late 1920s. Chemists, historians of science and technology, and those interested in world fertilizer production and the development of chemical industry during the first four decades of the twentieth century will find this book of considerable value.

Nitrogen Deposition, Critical Loads and Biodiversity

by Mark A. Sutton Kate E. Mason Lucy J. Sheppard Harald Sverdrup Richard Haeuber W. Kevin Hicks

This volume brings together extended reviews and papers of new scientific research on atmospheric nitrogen deposition impacts globally. While there is a wealth of evidence on the magnitude, components and effects of nitrogen disposition on floral biodiversity in Europe and North America, there is an obvious lack of information on impacts on above- and below-ground fauna, and all impacts in other parts of the world, with no clear overview of how the different strands of evidence fit together. This overall synthesis is targeted at the international conventions, but is equally readable for scientists, environmental managers, conservation agencies and policy makers. 'This timely book highlights the global nitrogen deposition problem. Major regions of the world are exceeding sustainability thresholds for adverse effects on ecosystem function and biodiversity. This highlights the importance of ongoing work, including under the Convention on Biological Diversity, in developing indicators and monitoring nitrogen deposition effects to enable appropriate measures. This book presents a milestone towards this global goal as the international community works toward meeting the Aichi Biodiversity Targets, especially Target 8: "By 2020, pollution, including from excess nutrients, has been brought to levels that are not detrimental to ecosystem function and biodiversity". Braulio Ferreira de Souza Dias, Executive Secretary, Convention on Biological Diversity "This key volume highlights the global challenge to reduce atmospheric nitrogen pollution resulting from energy production, transport and agricultural activities. It takes forward the agenda recently launched in the UNEP commissioned report 'Our Nutrient World". Dr. Anjan Datta, UNEP.

Nitrogen Fixing Bacteria: Sustainable Growth of Non-legumes (Microorganisms for Sustainability #36)

by Dinesh Kumar Maheshwari Shrivardhan Dheeman Rajendra Dobhal

This book covers aspects of biological nitrogen fixation along with the unique signaling and interaction between the diazotrophic bacteria and plants, especially the non-legumes. Nitrogen is the most important growth-limiting nutrient in the ecosystems and biological nitrogen fixation involving microbial symbionts, mainly rhizobia and legumes holds enormous interest across the globe. However, free-living rhizobacteria of non-legumes especially cereals, also establish themselves within the root system, fixing nitrogen and contributing to plant productivity, soil fertility, and agricultural sustainability. These non-symbiotic nitrogen fixers additionally exhibit various plant growth-promoting traits elevating productivity, fortifying nutrient content, and managing water stress in plants. The recent perspectives highlighting the mechanisms and background of non-symbiotic nitrogen fixation provide answers to unravel the potential of nitrogenase and various spectra of habitats of rhizobia and other diazotrophic bacteria. Further, the application of genetic engineering and the development of nitrogen-fixing cereals can provide a possible solution to the problem of food shortage. The book includes various scientific inputs providing comprehensive knowledge about the emergence of agricultural sustainability through nitrogen-fixing bacteria. The book illustrates the systematic mechanisms involved in biological nitrogen fixation through various illustrations, schematic drawings, and flow charts aiding in better understanding. The chapters elaborate on the physiology and metabolism of plant-bacteria interaction in different crops under diverse environmental conditions. Thus, the volume will provide a holistic scenario helping in advancing the novel plant-microbe interactions, cell-signaling, and plant-molecular interactions. The book will assist the agronomists, microbiologists, ecologists, plant pathologists, molecular biologists, environmentalists, policymakers, conservationists, and NGOs to develop biofertilizers and bioinoculants using various genera of microbes and contribute to the targets of sustainable goals in an eco-friendly manner.

Nitrogen Removal Characteristics of Aerobic Denitrifying Bacteria and Their Applications in Nitrogen Oxides Emission Mitigation (Springer Theses)

by Maosheng Zheng

This book systematically investigates the nitrogen removal characteristics of two screened aerobic denitrifying bacteria and their applications in nitrogen oxides emissions reduction. It reveals that Pseudomonas stutzeri PCN-1 possesses excellent capacity for aerobic nitrogen removal, regardless of whether nitrate, nitrite or N2O were taken as denitrification substrates. It also demonstrates that the rapid N2O reduction is due to the coordinate expression of denitrification genes. Further, the book discusses the bioaugmentation experiments conducted in denitrifying SBR and a pilot-scale Carrousel oxidation ditch, which confirmed that the strain could significantly enhance denitrification performance, reduce N2O emission and improve system stability. The second strain, P.aeruginosa PCN-2 accumulated negligible NO during aerobic nitrate and nitrite removal and efficiently removed NO from flue gas. This study is of great significance for potential applications of aerobic denitrification in mitigating nitrogen oxides emissions from biological nitrogen removal systems.

Nitrogen and Climate Change

by Dave Reay

It is the perfect storm. Limited food, water and energy unequally spread between an expanding population, and a warming climate as the bitter icing on the cake. In all these global challenges nitrogen has a leading role to play. In Nitrogen and Climate Change, Dave Reay looks at just how hard-wired into all of human civilisation nitrogen is, and whether the future will see it as our quiet savior or the toxic villain of the piece. Its story is of the peculiar and the mundane, of water turning red and people turning blue. It is one of climate friend and pollution foe, of meaty feasts and looming famine. If your main thought of nitrogen is as a boring corner of the periodic table, then it is time to look again.

Nitrosyl Complexes in Inorganic Chemistry, Biochemistry and Medicine I

by D. Michael P. Mingos

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. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

No Better Time: The Brief, Remarkable Life of Danny Lewin, the Genius Who Transformed the Internet

by Molly Knight Raskin

No Better Time tells of a young, driven mathematical genius who wrote a set of algorithms that would create a faster, better Internet. It's the story of a beautiful friendship between a loud, irreverent student and his soft-spoken MIT professor, of a husband and father who spent years struggling to make ends meet only to become a billionaire almost overnight with the success of Akamai Technologies, the Internet content delivery network he cofounded with his mentor.Danny Lewin's brilliant but brief life is largely unknown because, until now, those closest to him have guarded their memories and quietly mourned their loss. For Lewin was almost certainly the first victim of 9/11, stabbed to death at age 31 while trying to overpower the terrorists who would eventually fly American Flight 11 into the World Trade Center. But ironically it was 9/11 that proved the ultimate test for Lewin's vision--while phone communication failed and web traffic surged as never before, the critical news and government sites that relied on Akamai--and the technology pioneered by Danny Lewin--remained up and running.
