The Effect of Micro Turbulence on Quartz Flotation Rate [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2015 In this research, the effect of micro turbulence on the flotation rate of quartz particles was investigated. The maximum particle Reynolds number (Rep) was obtained at 60.25 with a particle size of -500+420 µm, impeller speed of 900 rpm, bubble surface ...

Bubble properties of heterogeneous bubbly flows in a square bubble column [PDF]
AIP Conference Proceedings, 2010 The present work focuses on the measurements of bubble properties in heterogeneous bubbly flows in a square bubble column. A four-point optical fibre probe was used for this purpose. The accuracy and intrusive effect of the optical probe was investigated first.

Experimental study of bubble-drag interaction in a Taylor-Couette flow [PDF]
, 2013 This study is an experimental investigation of the interactions between the bubbles, the coherent motion and the viscous drag in a Taylor Couette flow, for the outer cylinder at rest. The cylinder radius ratio is 0.9.

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]
, 2004 The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
