The concept of the dual-frequency electromagnetic (EM) shaping of liquid metal is first presented.
For zooming, changes in the shape of liquid lens elements replace the mechanical parts that shift the relative positions of glass or plastic lenses.
Furthermore, a more practical cylindrical shape of liquid metal bulk driven by a permanent helical magnetic field has been achieved.
Visual representations of abiotic, mechanical analogues provided the plausibility, such as the shape of liquid splashes or hanging drops for the cup and bell configurations of the free-swimming sexual stage of jellyfish.
The equilibrium shape of liquid metal inclusions in oxides is used to study anisotropy and oxygen partial pressure dependency of the metal oxide specific interfacial free energy.
The shape of liquid Pb inclusions embedded in a solid Al matrix was investigated at temperatures between 300 and 500°C using in-situ electron microscopy.
It is revealed that the addition of hydrophilic pores has a negligible impact on liquid saturation profile when the hydrophilic fraction is low (⩽0.2), whereas in the case of higher hydrophilic fraction (⩾0.4), a flat shape of liquid saturation profile is observed along the GDL thickness.
Our results are consistent with experimental observations [Acta Mater 2001 49 4259], based on the equilibrium shape of liquid Pb inclusions in solid Al just above the melting temperature of Pb, that the (1 1 1) interface is faceted, while the (1 0 0) and (1 1 0) interfaces are rough.
Surface tension is responsible for the shape of liquid droplets.
Interfacial tension is a physical rating of the difference between the intermolecular force of the two liquids and it is responsible for the shape of liquid bubbles.
