DBG-Symposium: Recent topics in the characterization and application of minerals in soil systems, am 19. un 20. Juli 2022 im iFZ des JLU Giessen

Trotz Rekordtemperaturen fand ein anregender Austausch zu Stukturcharakterisierung, Anwendung und Reaktivität von Bodenmineralen in entspannter Atmosphäre statt. Für Abkühlung sorgte zwischenzeitlich ein Eis und der gesellige Abend am Lahnufer. Für eine Übersicht der Vorträge und Poster siehe Auflistung unten.
