Ionic liquids (ILs) offer a wide range of promising applications because of their much
enhanced properties. However, further development of such materials depends on the …

Iron oxide nanoparticle (ION)-based ferro-nanofluids (FNs) have been used for different
technological applications owing to their excellent magneto-rheological properties. A …

Hydrological droughts are characterized based on their duration, severity, and magnitude.
Among the most critical factors, precipitation, evapotranspiration, and runoff are essential in …

We present a comprehensive literature review on the two-phase bubble column; in this
review we deeply analyze the flow regimes, the flow regime transitions, the local and global …

Photosynthetic biogas upgrading using microalgae provides a promising alternative to
commercial upgrading processes as it allows for carbon capture and re-use, improving the …

Some authors, in the last decades, have observed the dual effect of viscosity on gas holdup
and flow regime transition in small-diameter and small-scale bubble columns. This work …

An understanding of the bubble properties, size distributions and shapes is of fundamental
importance for comprehending flow dynamics and mass transfer phenomena in bubble …

In this paper, we apply a variety of experimental techniques to investigate the influence of
the counter-current mode on bubble column hydrodynamics. We study an air–water bubble …

The correct design, operation and scale-up of bubble columns rely on the knowledge of the
fluid dynamics at the “bubble-scale” and at the “reactor-scale”. This paper contributes to the …

Membrane processes (ultrafiltration, membrane bioreactor, reverse osmosis) are relevant for
the remediation of wastewater as they generate large volumes of high-quality permeate …
