Die Wassermetaphorik als Grenzraumgestaltung in Uwe Tellkamps „Der Turm“ (2008)

Español El objetivo de este capítulo es analizar las metáforas del agua como elementos clave para la representación literaria de los espacios de frontera relacionados con la última fase de la República Democrática Alemana en la novela Der Turm de Uwe Tellkamp. El análisis se centra en los siguientes motivos y temas topográficos: Atlantis como negación de la utopía de la RDA; Archipiélago e isla como contraposición a la imagen continente de la utopía de la RDA; Aguas residuales y agua estancada como oposición al agua fluída en el barrio heterotópico de la torre; Fuentes y arroyos como símbolos del inconsciente (colectivo); y, por último, fluidez y porosidad como imágenes que visualizan la historia. El uso de estas metáforas no sólo cuestiona la topografía oficial del aparato estatal y del partido en la RDA y los diversos espacios fronterizos, sino que las imágenes de fluidez y porosidad también representan la discursividad de la memoria y la memoria colectiva en relación con el pasado de la RDA. La Dresde atlante de Der Turm de Tellkamp se representada mediante metáforas acuáticas como un universo topográfico, social e ideológico ambivalente y complejo con numerosos espacios fronterizos interiores y exteriores. English The aim of this chapter is to analyze the water metaphors as key elements for the literary representation of borderland spaces in the late German Democratic Republic in the novel The Tower by Uwe Tellkamp. The analysis focuses on the following topographic motives and topics: Atlantis as a denial of the GDR utopia; Archipelago and island as a contrast of the image continent of the GDR utopia; Wastewater and dammed up water as opposed to running water in the heterotopic tower district; fountains and streams as symbols of (collective) unconscious; and finally, fluidity and porosity as images of history. Not only does the use of these metaphors question the official topography of the state and party apparatus and the various borderland spaces, but images of fluidity and porosity also represent the discursiveness of memory and collective memory in relation to GDR’s past. The Atlantean Dresden in Tellkamp’s The Tower is portrayed by means of water metaphors as an ambivalent and complex topographical, social and ideological universe with many inner and outer borderland spaces.MINECO, proyecto de investigación FFI2017-84342-

Long-Distance Rate Acceleration by Bulk Gold

Schlimm A, Loew R, Rusch T, et al. Long-Distance Rate Acceleration by Bulk Gold. ANGEWANDTE CHEMIE-INTERNATIONAL EDITION. 2019;58(20):6574-6578.We report on a very unusual case of surface catalysis involving azobenzenes in contact with a Au(111) surface. A rate acceleration of the cis-trans isomerization on gold up to a factor of 1300 compared to solution is observed. By using carefully designed molecular frameworks, the electronic coupling to the surface can be systematically tuned. The isomerization kinetics of molecules with very weak coupling to the metal is similar to that found in solution. For their counterparts with strong coupling, the relaxation rate is shown to depend on the spin-density distribution in the triplet states of the molecules. This suggests that an intersystem crossing is involved in the relaxation process. Aside from their impact on catalytic processes, these effects could be used to trigger reactions over long distances
