Bioprocesses are scaled up for the production of large product quantities. With larger
fermenter volumes, mixing becomes increasingly inefficient and environmental gradients get …

Modern bioprocess monitoring demands sensors that provide on‐line information about the
process state. In particular, sensors for monitoring bioprocesses carried out in single‐use …

Production-scale fermentation processes in industrial biotechnology experience gradients in
process variables, such as dissolved gases, pH and substrate concentrations, which can …

This work presents a bio-processing online device (bPod) platform, capable of real-time in
situ monitoring of bioreactor cell culture parameters, such as dissolved oxygen (DO). The …

Due to high mixing times and base addition from top of the vessel, pH inhomogeneities are
most likely to occur during large‐scale mammalian processes. The goal of this study was to …

The scale‐up of bioprocesses remains one of the major obstacles in the biotechnology
industry. Scale‐down bioreactors have been identified as valuable tools to investigate the …

Studies on the dynamics of particles in turbulence have recently experienced advances in
experimental techniques, numerical simulations and theoretical understandings. This' focus …

We report experimental measurements of the translational and rotational dynamics of a
large buoyant sphere in isotropic turbulence. We introduce an efficient method to …

Understanding the penetration dynamics of intruders in granular beds is relevant not only for
fundamental physics, but also for geophysical processes and construction on sediments or …

The application of standard sensor electrodes is often limited to stirred tank reactors due to
their wired nature and their large space requirement. For other cultivation systems, sensors …
