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.

The study of Soviet youth has long lagged behind the comprehensive research conducted on Western European youth culture. In an era that saw the emergence of youth movements of all sorts across Europe, the Soviet Komsomol was the first state-sponsored youth organization, in the first communist country. Born out of an autonomous youth movement that emerged in 1917, the Komsomol eventually became the last link in a chain of Soviet socializing agencies which organized the young. Based on extensive archival research and building upon recent research on Soviet youth, this book broadens our understanding of the social and political dimension of Komsomol membership during the momentous period 1917–1932. It sheds light on the complicated interchange between ideology, policy and reality in the league's evolution, highlighting the important role ordinary members played. The transformation of the country shaped Komsomol members and their league's social identity, institutional structure and social psychology, and vice versa, the organization itself became a crucial force in the dramatic changes of that time. The book investigates the complex dialogue between the Communist Youth League and the regime, unravelling the intricate process that transformed the Komsomol into a mere institution for political socialization serving the regime's quest for social engineering and control.

Die Arbeit untersucht die Behandlung von Geruchten als unsicheren Informationen im Kapitalmarktrecht. Dazu werden zunachst psychologische und soziologische sowie oekonomische Erkenntnisse zu Geruchten allgemein und Kapitalmarktgeruchten im Besonderen betrachtet. Daran anknupfend werden ubergeordnete rechtspolitische UEberlegungen angestellt. Es folgt ein Blick darauf, wie Geruchte ausserhalb des Kapitalmarktrechts rechtlich eingeordnet werden. Kern der Arbeit ist die Behandlung von Geruchten im Insiderrecht, bei der Ad-hoc-Publizitat, im Rahmen des Marktmanipulationsverbots sowie bei den Tatbestanden der Handelsaussetzung de lege lata. Zudem werden UEberlegungen angestellt, wie die kapitalmarktrechtliche Behandlung von Geruchten de lege ferenda verbessert werden koennte.
