Publikováno v: Journal of Membrane Science. 466:361-369

This work systematically investigates and models the retention behavior in organic solvent nanofiltration in solvent mixtures using a dense PDMS-based composite membrane. Experiments with n-alkanes as solutes with different chain lengths (142–339 k

Publikováno v: Bioresource Technology. 291:121821

The aim of this work was to study ammonium-limited fed-batch conditions in heterotrophic C. vulgaris shake flask cultivations. Therefore, an innovative polymer-based ammonium release technique (polymer beads) was developed. Using these beads in shake
