Systematic investigation of thermal process parameters on the morphology of spray-freeze-dried powders Annika Rautenberg, José Ignacio Vázquez-Olvera, Paul Bühlbecker, Alf Lamprecht Abstract Hypothesis: During spray freeze drying (SFD), vitrification, recrystallization, and polymorphic transitions govern particle morphology and mechanical integrity. We hypothesize that with control over freezing temperature, annealing relative to the glass transition of the maximally… Continue reading Systematic investigation of thermal process parameters on the morphology of spray-freeze-dried powders
