Wetting and self-cleaning properties of artificial superhydrophobic surfaces
TL;DR: The wetting and the self-cleaning properties (the latter is often called the "Lotus-Effect") of three types of superhydrophobic surfaces have been investigated: silicon wafer specimens with different regular arrays of spikes hydrophobized by chemical treatment, replicates of water-repellent leaves of plants, and commercially available metal foils which were additionally hydrophobic by means of a fluorinated agent.
Journal ArticleDOI
The impact of spray drying outlet temperature on the particle morphology of mannitol
Stephan Maas,Gerhard Schaldach,Eva Maria Littringer,Axel Mescher,Ulrich J. Griesser,Doris E. Braun,Peter Walzel,Nora Anne Urbanetz +7 more
TL;DR: In this paper, it was shown that mannitol particles of different surface roughness can be prepared by spray drying at different outlet temperatures, providing the opportunity of tailoring the contact area respectively the interparticle interactions between the drug and the carrier.

Spray Drying of Mannitol as a Drug Carrier—The Impact of Process Parameters on Product Properties
Eva Maria Littringer,Axel Mescher,Susanna Eckhard,Hartmuth Schröttner,Christoph Langes,Manfred Fries,Ulrich J. Griesser,Peter Walzel,Nora Anne Urbanetz +8 more
TL;DR: In this article, the influence of spray-drying process parameters on relevant product properties, namely, surface topography, size, breaking strength, and polymorphism of mannitol carrier particles intended for the use in dry powder inhalers, was investigated.
