Journal ArticleDOI
Use of roller compaction and fines recycling process in the preparation of erlotinib hydrochloride tablets.
TL;DR: The application of the fines recycling process at commercial scale resulted in reliable dissolution performance and batch‐to‐batch consistency, which were further confirmed by bioequivalence to the reference product.
Direct shear testing of food powders flowability - influence of deformation speed and apparatus stiffn ess
Mateusz Stasiak,Marek Molenda +1 more
TL;DR: In this article, the authors investigated the influence of speed and stiffness of food powders on their flowability and found that an increase in speed resulted in flow functions of valuations characteristic for cohesive materials.

Vibrational flow of cohesive powders
Th. Kollmann,Jürgen Tomas +1 more
TL;DR: In this article, the application of mechanical vibrations leads to a significant reduction of the shear strength and the unconfined yield strength of fine powders and the test results could be successfully described by the failure criterion according to Roberts.
Book ChapterDOI
Die Fill and Powder Transfer
TL;DR: In this paper, the density distribution of powder beds in filled dies has been investigated and it has been suggested that variations of the order of 10 % to 15 % in local powder density can be developed.
Journal ArticleDOI
In-situ gradient formation by direct solid addition of buffer components.
TL;DR: A device for an in-line gradient delivery of buffering agents directly from solids to be applied for chromatographic separation processes, generating the gradient by the direct addition of solids avoiding the necessity of additional pumps and hold tanks is developed.
