Webinar title: Particle Engineering in Pharmaceutical Solids Processing: Surface Energy Considerations
Topic: This webinar presented by Dr Daryl Williams from Imperial College London reviews the surface energy and surface energy heterogeneity of crystalline solids, methods for the measurement of surface energy, effects of milling on powder surface energy, adhesion and cohesion on powder mixtures, crystal habits and surface energy, surface energy and powder granulation processes.

View allThis session will explores well-established vapor sorption techniques of Dynamic Vapor Sorption (DVS) and Inverse Gas Chromatography (IGC). With a focus on applications, the webinar delves into the physicochemical characterization capabilities offered by the DVS and IGC, specific to polymers and films.
In particular to IGC, practical examples and case studies are given that cover a wide range of relevant problems, including surface energetics, wetting behavior, composite adhesion/cohesion phenomena, solubility parameters, and glass transitions.
Related to DVS, examples and case studies are reviewed that provide insight into moisture sorption properties, drying kinetics, vapor-induced phase changes, and vapor diffusion/permeability studies. Also, the hypenization of the DVS with video microscopy and Raman spectroscopy is discussed including examples on relevant materials.
