Power-to-Gas technologies are considered essential for a green transition of the global
energy system by producing fossil-free fuel from renewable electricity and CO 2. Biological …

Air-water micronanobubbles MNBs can be produced by four different methods and be used
to improve (1) oxygen transfer in microbiological processes with high consumption rate,(2) …

Bubbles transport methane (CH4) released from the sea bed to the surface while
exchanging gas with the surrounding aqueous environment. The fraction of CH4 released at …

Synthesis‐gas fermentations have typically been gas‐to‐liquid mass‐transfer‐limited due to
low solubilities of the gaseous substrates. A potential method to enhance mass‐transfer …

A steady bubble plume model is developed to describe a weak air (or oxygen) bubble
injection system used for the restoration of deep stratified lakes. Since the model is designed …

Microbubble-based methods, in recent times, have been widely used for purification of water
and wastewater. Microbubbles have several physicochemical properties, which make them …

Microalgae fix CO2 as energy source and afford biomass and high valued products such as
carotenoids, pigments, proteins, and vitamins that can be used for the production of …

In the present paper, the effect of liquid properties (surfactants) on bubble generation
phenomenon, interfacial area and liquid-side mass transfer coefficient was investigated. The …

Rühren gehört zu den Vereinigungsprozessen, die einen Teil der mechanischen
Grundoperationen der Verfahrenstechnik ausmachen. Es handelt sich um eine bedeutende …

Bubbly flow is a prototypical two-phase flow problem. The dynamic behavior of bubbles
within a reactor is intrinsically linked to their transport, distribution, and mass transfer, all of …
