Schwer wiegt die Krone: Kronenethermodulation von Kobaltporphyrinen in der CO2 Elektroreduktion in Zero‐Gap Electrolyseuren

open access: yesAngewandte Chemie, EarlyView.
Die Implementierung von Kronenethern in den Liganden von Kobaltporphyrinen wirkt sich in mehrfacher Hinsicht positiv auf die elektrochemische CO2‐Reduktion aus: 1. Das Reduktionspotenzial wird in Gegenwart von K+ gesenkt; 2. die CO‐Erzeugung in Zero‐Gap‐Elektrolyseuren wird gesteigert und 3.

Selbstassemblierte (Aza‐)BODIPY Farbstoffe für Biomedizinische In Vivo Bildgebung

open access: yesAngewandte Chemie, EarlyView.
Dieses Minireview klassifiziert (Aza‐)BODIPY‐Farbstoffe anhand ihrer molekularen Stapelungsmodi und Aggregattypen (H‐, oblique‐ oder J‐Typ) in wässrigen Medien und setzt diese Merkmale in Beziehung zu ihrer multimodalen Bildgebungsleistung. Durch die Verknüpfung von molekularem Design, Exzitonenkopplung und pfadabhängiger Assemblierung stellen wir ...

Water destruction by X-rays in young stellar objects

open access: yes, 2006
We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemistry is modeled as a function of time, hydrogen density and X-ray flux. To

Schnelle RASER‐MRT

open access: yesAngewandte Chemie, EarlyView.
Schnelle RASER‐MRT ermöglicht Bildgebung ohne RF‐Anregung. Stattdessen wird eine Populationsinversion der Kernspins durch SABRE‐Hyperpolarisation erzeugt, die eine Selbstanregung durch RASER ermöglicht. Wenn die gewünschte transversale Magnetisierung aufgebaut ist, wird herkömmliche EPI‐Kodierung ausgelöst, um das Bild aufzuzeichnen.
