Before Darwin . . . before Lewis and Clark . . . there was Alexander von Humboldt. Explorer. Naturalist. All-around genius. Lost hero of science. In his time, Alexander von Humboldt (1769–1859) was world-famous. Why? He led one of the first major scientific expeditions into the South American rain forest and another into the wilds of Siberia. Carrying fragile instruments, he navigated perilous rapids and climbed the volcano of Tenerife. He observed animals, plants, and cultures that no one in Europe had ever dreamed of, and his books about them inspired a whole generation of scientists—including Charles Darwin. But before he did any of that, he was a little boy who was curious about everything (especially bugs)! The Incredible yet True Adventures of Alexander von Humboldt will whisk you away to another time and place. Meet the young man who, defying his mother’s wishes, became a daring explorer-scientist—and follow along as he makes his amazing discoveries. Lavish illustrations bring Humboldt’s untamed world to life. See nature through the eyes of a great early scientist. Wonder awaits!

While America's relationship with Britain has often been deemed unique, especially during the two world wars when Germany was a common enemy, the American business sector actually had a greater affinity with Germany for most of the twentieth century. American Big Business in Britain and Germany examines the triangular relationship between the American, British, and German business communities and how the special relationship that Britain believed it had with the United States was supplanted by one between America and Germany. Volker Berghahn begins with the pre-1914 period and moves through the 1920s, when American investments supported German reconstruction rather than British industry. The Nazi seizure of power in 1933 led to a reversal in German-American relations, forcing American corporations to consider cutting their losses or collaborating with a regime that was inexorably moving toward war. Although Britain hoped that the wartime economic alliance with the United States would continue after World War II, the American business community reconnected with West Germany to rebuild Europe’s economy. And while Britain thought they had established their special relationship with America once again in the 1980s and 90s, in actuality it was the Germans who, with American help, had acquired an informal economic empire on the European continent. American Big Business in Britain and Germany uncovers the surprising and differing relationships of the American business community with two major European trading partners from 1900 through the twentieth century.
This open access book presents a thorough look at tortuosity and microstructure effects in porous materials. The book delivers a comprehensive review of the subject, summarizing all key results in the field with respect to the underlying theories, empirical data available in the literature, modern methodologies and calculation approaches, and quantitative relationships between microscopic and macroscopic properties. It thoroughly discusses up to 20 different types of tortuosity and introduces a new classification scheme and nomenclature based on direct geometric tortuosities, indirect physics-based tortuosities, and mixed tortuosities (geometric and physics-based). The book also covers recent progress in 3D imaging and image modeling for studying novel aspects of tortuosity and associated transport properties in materials, while providing a comprehensive list of available software packages for practitioners in the community. This book is a must-read for researchers and students in materials science and engineering interested in a deeper understanding of microstructure–property relationships in porous materials. For energy materials in particular, such as lithium-ion batteries, tortuosity is a key microstructural parameter that can greatly impact long-term material performance. Thus, the information laid out in this book will also greatly benefit researchers interested in computational modeling and design of next-generation materials, especially those for sustainability and energy applications.
