This book discusses the basic principles and processes of solar energy conversion in natural photosynthesis. It then directly compares them with recent developments and concepts currently being pursued in artificial photosynthetic systems that are capable of utilizing sunlight to convert carbon dioxide and water into a chemical fuel. In this regard, the main focus is on photoelectrochemical cells, in which semiconducting photoanodes and -cathodes modified with (electro-) catalysts are used to oxidize water, produce hydrogen and reduce carbon dioxide in a monolithic device. The fundamental photochemical and photophysical processes involved are presented and discussed, along with protection mechanisms and efficiency calculations for both natural and artificial photosynthesis. In turn, key parameters that are crucial for the efficient operation of natural photosynthesis are identified. Lastly, their validity and applicability in the design of artificial solar-driven water-splitting systems are examined.

Ein Leben ohne E-Mail-Account und soziale Netzwerke – für viele kaum noch vorstellbar. Doch was geschieht mit den Benutzerkonten und den gespeicherten Kommunikationsinhalten, wenn der Inhaber des Accounts verstirbt? Können die Erben den Provider auf Herausgabe der Zugangsdaten in Anspruch nehmen? Oder bleibt ihnen aus Gründen des postmortalen Persönlichkeitsschutzes der Zugang verwehrt? Die Dissertation befasst sich mit diesen höchst aktuellen Fragen und untersucht das postmortale Schicksal der elektronischen Kommunikation umfassend aus den Blickwinkeln des Erbrechts, des Persönlichkeitsrechts, des Vertragsrechts, des Datenschutzrechts sowie des Telekommunikationsrechts. Weiterhin wird auf Gestaltungsmöglichkeiten der Provider sowie auf denkbare Vorsorgemaßnahmen der Nutzer eingegangen.
Robert G. Moeller is the first historian of modern German women to use social policy as a lens to focus on society's conceptions of gender difference and "woman's place." He investigates the social, economic, and political status of women in West Germany after World War II to reveal how the West Germans, emerging from the rubble of the Third Reich, viewed a reconsideration of gender relations as an essential part of social reconstruction. The debate over "woman's place" in the fifties was part of West Germany's confrontation with the ideological legacy of National Socialism. At the same time, the presence of the Cold War influenced all debates about women and the family. In response to the "...
In diesem Buch stellt die Autorin Sabine Wegner-Kirchhoff anschaulich und anhand von Beispielen aus ihrer langjährigen Beratungspraxis unterschiedliche Prozesse der Konfliktbearbeitung dar. Ziel des Konfliktcoaching ist es, beteiligte Konfliktparteien an einen Tisch zu holen, ein Verständnis für die Sichtweisen der Gegenseite zu entwickeln und damit entstandene Blockadehaltungen aufzugeben.
