Photochemistry is an important part of both chemistry and biology and is of great practical significance for the development of sustainable sources of energy. The mechanisms of photochemistry are far from trivial and far from understood. There are limits to how well theory can describe the processes and how well experiments can resolve them. This book aims to provide an overview of state-of-the-art methods for both theoretical development and experimental techniques, with a focus on ultrafast molecular processes and electronic excitation of organic molecules. These fields are active and progress is being made, carried by the increasing speed of computation and the development of new light so...
This thesis investigates the transitions from one electronically excited state to another. Such processes - the fastest of events in chemistry - can be studied with femtosecond resolution, and Thomas S. Kuhlman approaches the question both with experimental and theoretical methods. His approach contributes to explain processes of high importance to all scientific fields concerned with the interaction between light and matter: the deactivation of the electronically excited states after excitation. Thomas S. Kuhlman concludes in this thesis that the electronic transition proceeds before the entire set of available degrees of freedom are active - 'It is as simple as that' !
In 2012, Jennifer Schell brought together 160 of the Okanagan Valley's best chefs, wine makers, and food producers to create The Butcher, the Baker, the Wine and Cheese Maker: An Okanagan Cookbook. It was an instant success, selling more than 7000 copies and winning national and global awards. Updated to reflect the constant evolution of food production and culture in the famed valley, this second edition includes profiles of the newest players in the area's culinary scene, new recipes and food and wine pairings, and updated profiles of the region's renowned and respected farmers, producers, artisans and agricultural innovators. In addition to delicious recipes for every meal, such as Quinoa Crusted Falafel Mignon, Sezmu Beef Tartare, Okanagan Lavender Mascarpone Souffle, and Saskatoon Berry Pie, this collection features the stories of the area's experts, and a listing of the area's foodie festivals and events.
Rasmus Brogaard's thesis digs into the fundamental issue of how the shape of a molecule relates to its photochemical reactivity. This relation is drastically different from that of ground-state chemistry, since lifetimes of excited states are often comparable to or even shorter than the time scales of conformational changes. Combining theoretical and experimental efforts in femto-second time-resolved photoionization Rasmus Brogaard finds that a requirement for an efficient photochemical reaction is the prearrangement of the constituents in a reactive conformation. Furthermore, he is able to show that by exploiting a strong ionic interaction between two chromophores, a coherent molecular motion can be induced and probed in real-time. This way of using bichromophoric interactions provides a promising strategy for future research on conformational dynamics.
Das Buch zu Jahreslosung 2022: Abgewiesen. Ausgestoßen. Links liegen gelassen. Gemobbt. Wer solche Erfahrungen schon einmal gemacht hat, wird sich bei der Jahreslosung 2022 wiederfinden. Über 40 bekannte Persönlichkeiten aus Kirche und Gesellschaft erzählen von ihren Erfahrungen mit dem Text der Jahreslosung 2022, "Jesus Christus spricht: Wer zu mir kommt, den werde ich nicht abweisen" (Joh 6,37). Sie berichten von eigenen Erfahrungen, (nicht) abgewiesen worden zu sein, aber auch davon, wie schwer es ist, manche Menschen nicht selbst nicht irgendwann wegzuschicken, weil "es einfach nicht mehr geht" oder weil alle Mühe aussichtslos erscheint. Bei Gott, bei Jesus ist das nie der Fall. Auch nicht, wenn Menschen zum ersten Mal zu ihm kommen und "anklopfen". Das haben auch viele der über 40 bekannten Persönlichkeiten erlebt, die bei diesem Band mitgeschrieben haben. Sie haben erlebt, bei Gott wird niemand abgewiesen und jeder ist willkommen. . Die persönlichen Zeugnisse und biblischen Besinnungen lassen die Jahreslosung zum Begleiter durch das Jahr werden – nicht nur für das eigene Leben, sondern auch als Fundgrube für die Gemeindearbeit.
