Freeze drying microscopy as a tool to study sublimation kinetics
Published 2015“…Cooling rates were mainly found to affect the surface resistance rather than bulk resistance and this may be due to different levels of surface drying when the samples are being cooled for different lengths of time. Annealing substantially changed the ice crystal sizes, and had a beneficial effect on freeze drying rates and had a similar effect to adding AgI. …”
