Abstract

original image

Keine Sterne in ALPO-5: Sternmuster in konfokalen Fluoreszenzmikroskopie(CFM)-Bildern von großen Kristallen mesoporöser AlPO-5-Materialien stammen von Barrieren der Moleküldiffusion im Inneren der Kristalle (siehe Bild) und nicht von sternförmigen Unterkristallen, wie aus Untersuchungen mit CFM, fokussierten Ionenstrahlen, Rückstreuelektronenbeugung und Rasterkraftmikrokopie geschlossen wurde.
