Minimum size for the top jet drop from a bursting bubble

Size limits the formation of liquid jets during bubble bursting

A bubble reaching an air-liquid interface usually bursts and forms a liquid jet. Jetting is relevant to climate and health as it is a source of aerosol droplets from breaking waves. Jetting has been observed for large bubbles with radii of R≫100 μm. However, few studies have been devoted to small bubbles (R<100 μm) despite the entrainment of a large number of such bubbles in sea water. Here we ...

The Bursting of the Pedigree Bubble

Centaurus A : multiple outbursts or bursting bubble ?

We present new radio observations of the brighter region of the northern lobe (the Northern Middle Lobe, NML) of Centaurus A obtained at 20 cm with the Australia Telescope Compact Array. The angular resolutions are ∼50 and ∼130 arcsec, therefore much higher than for the previously available radio images of this region. The most interesting feature detected in our images is a large-scale jet tha...

Bursting the bubble on bacterial biofilms: a flow cell methodology

The flow cell biofilm system is an important and widely used tool for the in vitro cultivation and evaluation of bacterial biofilms under hydrodynamic conditions of flow. This paper provides an introduction to the background and use of such systems, accompanied by a detailed guide to the assembly of the apparatus including the description of new modifications which enhance its performance. As s...
