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

Angewandte 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

Angewandte 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 ...

Survival outcomes and prognostic factors of gastric carcinoma with neuroendocrine differentiation

International Journal of Cancer, EarlyView.
What's New? Although gastric carcinoma with neuroendocrine differentiation (GCNED) is associated with more aggressive features than conventional GC, its prognosis and survival remain poorly defined. To better understand survival patterns, the authors of the present study examined clinicopathological and prognostic features of GCNED patients following ...

Molecular–clinical characteristics and treatment outcomes in 163 metastatic colorectal neuroendocrine carcinomas with a comparison to colorectal adenocarcinomas

International Journal of Cancer, EarlyView.
What's New? Colorectal neuroendocrine carcinoma (CR‐NEC) is a rare digestive neuroendocrine neoplasm that frequently exhibits an adenocarcinoma component. Nonetheless, the underlying biology of CR‐NEC remains poorly understood. This study examined molecular and clinical features and palliative chemotherapy outcomes of metastatic CR‐NEC, with comparison

Fallschirmspringen, Paragliding und Wingsuit‐Fliegen: Im freien Fall

Physik in unserer Zeit, EarlyView.
Mit nichts als Schwerkraftantrieb vom Himmel zu fallen, führt zu den schnellsten Sportarten, aber auch zu den gefährlichsten. Zusammenfassung Fallschirmspringen wird erst seit 1951 als offizielle Sportart betrieben. Moderne Fallschirme sind sehr gut steuerbar, weshalb zum Beispiel das Zielspringen immer anspruchsvoller wird.
