Near-wall particle depletion in a flowing colloidal suspension
In this paper a method based on attenuated total reflection–Fourier-transform infrared spectroscopy is described to measure the concentration of colloidal particles dispersed in a liquid near a solidExpand
Gas Permeation Related to the Moisture Sorption in Films of Glassy Hydrophilic Polymers
The purpose of this article is to elucidate the effect of integral sorption of moisture on gas permeation in glassy hydrophilic polymers. The oxygen and the simultane- ous moisture sorption intoExpand
Development of particulate pulse-release formulations and their mathematical description
Abstract In this contribution both the development of a multi-particulate delayed release system and a mathematical model to describe its release properties are presented. The formulation consists ofExpand
Using the Internal Stress Concept to Assess the Importance of Moisture Sorption-induced Swelling on the Moisture Transport through the Glassy HPMC Films
Investigations revealed that the loss of stress is especially due to the swelling of the polymer rather than the changes in the inherent strain of the HPMC films, which implies that the impact of the moisture sorption on the diffusivity is predominantly via volume addition rather than via altering the mechanical properties.

Mapping the droplet drying phenomena within a fluidized bed coater as a prediction tool for coating qualities
For a high coating quality, agglomeration and exces siv evaporation of the coating droplets during fluidized bed coating process should be avoi ded (1-3). This means that the coating process canExpand
