Investigation of Thermocapillary Flows Around Hemispherical Bubbles
Transient thermocapillary induced flows around a hemispherical bubble on a heated wall have been studied using numerical solutions for a wide range of Marangoni numbers (up to 10('6)). Natural convection effects and mass transfer at the bubble interface were included. Two distinct boundary …

Advanced purification of aligned arrays of single-walled carbon nanotubes
… strategies to address this issue. Nanoscale thermocapillary flows and subsequent etching serve as an effective way to remove the metallic impurities in perfectly aligned arrays of SWNTs grown on quartz substrates. We develop a nanoscale thermometry-scanning Joule expansion microscopy (SJEM) …

Multi-Scale Model of the Stability of a Laterally Heated Liquid Bridge Under the Influence of an Axial Magnetic Field
Thermocapillary flows, occurring in floating-zone semiconductor crystal growth, are studied using numerical and analytical linear stability analyses. In this process, a polycrystalline feed rod is passed through an optical heating source, where it melts and then re-solidifies into a single crystal. …

Thermocapillary convection in laser melted pools during materials processing
… is induced by buoyancy and surface tension (thermocapillary) forces. This motion of the liquid metal causes heat to be redistributed (convective heat transfer) which in turn effects the melt pool shape (solid/liquid interace), local temperature gradients, and ultimately, the microstructure of …

Sonoptics : applications of light and sound in the context of biomedicine
… this field is presented here where laser induced thermocapillary flows are shown to cause mixing of the content of a drop in a microfluidic channel in a bid to understand the mixing process at a level that may assist future microbubble engineering strategy. To summarise then, the work presented in …
