Melt-driven erosion in microparticle impact

Stability and erosion of melt layers

Melting of metallic plasma facing components such as tungsten (W) divertor, macroscopic melt motion, and melt splashing due to edge localized modes and plasma disruptions is a major concern in fusion devices such as ITER. The viscous stability analysis and computational modelling of coupled W-melt-plasma flows are performed using the developed volume-of-fluid magnetohydrodynamic code. The effec...

Compaction-driven melt segregation in migmatites

A common and puzzling feature of migmatite terranes is the presence of synkinematic leucosomes oriented perpendicular to the maximum principal compressive stress axis, s1, particularly leucosomes oriented parallel to the axial plane of folds. These are parallel to planes of compaction, but experiments predict that leucosomes should form in dilational bands oriented instead at small angles to s1...

Wireless on-chip microparticle manipulation using pulse-driven dielectrophoresis

A chip with which to manipulate microparticles using wireless power transfer and pulse-driven dielectrophoresis has been designed and fabricated using a 0.18-μm CMOS process. The chip enables microparticle manipulation under a 0.7-V power supply and a 13-MHz clock, which are generated on the chip by means of an on-chip coil, a rectifier, and a Schmitt trigger circuit.
