Time: 14:00 – 16:00 BST
The workshop covers in-depth Dynamic Vapor Sorption (DVS) and Inverse Gas Chromatography (iGC) techniques and its applications on studies of materials such as powders, films, nanomaterials, composites, polymers among others.
DVS system allows for real-time monitoring and controlling of vapor and gas concentration for sorption measurements in solid state materials. The sorption mechanism may be investigated from sorption/desorption isotherms, hysteresis effects, and sorption kinetics. The combination of a video microscope and vibrational spectroscopic techniques with DVS would allow for increased understanding of vapor-induced structural changes of solid materials.
Inverse Gas Chromatography on the other hand, is specially designed to determine the surface energy heterogeneity but nevertheless suitable for measuring different surface and bulk properties of solid materials including acid-base properties, heat of sorption, glass transition temperature, solubility parameters.
