Shaken flasks by resonant acoustic mixing versus orbital mixing: Mass transfer coefficient kLa characterization and Escherichia coli cultures comparison
Abstract Shaken flasks are widely applied in bioprocesses due to their flexibility and ease of operation. Resonant acoustic mixing (RAM) enables non-contact mixing by the application of low frequency acoustic energy, and is proposed as an...

Micro-scale CFD study about the influence of operative parameters on physical mass transfer within structured packing elements
Abstract In this work a VOF-based 3D numerical model is developed to study the influence of several operative parameters on the gas absorption into falling liquid films. The parameters studied are liquid phase viscosity, gas phase pressure and inlet ...

Yellow–colored mesoporous pure titania and its high stability in visible light photocatalysis
Abstract Yellow–colored pure titania with a mesoporous structure was prepared by the aggregate of titania nanocrystals, which were stabilized by exfoliated titanate nanosheets via an electrostatic interaction. X–ray diffraction patterns and images...

Drop impact behaviour on alternately hydrophobic and hydrophilic layered bead packs
Abstract A high level of water repellency in soils has an impact on soil hydrology, plant growth and soil erosion. Studies have been performed previously on model soils; consisting of close packed layers of glass spheres (140–400μm in diameter), to...

The 3D pore structure and fluid dynamics simulation of macroporous monoliths: High permeability due to alternating channel width
Abstract Polymethacrylate-based monoliths have excellent flow properties. Flow in the wide channel interconnected with narrow channels is theoretically assumed to account for favorable permeability. Monoliths were cut into 898 slices in 50nm...

Enhancing properties of iron and manganese ores as oxygen carriers for chemical looping processes by dry impregnation
Abstract The use of naturally occurring ores as oxygen carriers in CLC processes is attractive because of their relative abundance and low cost. Unfortunately, they typically exhibit lower reactivity and lack the mechanical robustness required, when ...
