TL;DR: In this article, an investigation showed that in liquid metal batteries, electrovortex flows can become so intense they can compromise the layered structure of the battery and cause a short circuit.
Abstract: Electrovortex flows occur whenever thin electrodes are put in contact with wider liquid metal regions. An investigation shows that in liquid metal batteries, electrovortex flows can become so intense they can compromise the layered structure of the battery and cause a short circuit.

TL;DR: In this paper, a fully solution-based process was proposed to generate patterned features of the liquid metal conductor. But the entire process is carried out under ambient conditions and is generally compatible with various elastomeric substrates, which may find a broad range of applications in emerging fields of epidermal sensors, wearable heaters, advanced prosthetics and soft robotics.
Abstract: Liquid metal represents a highly conductive and inherently deformable conductor for the development of stretchable electronics. The widespread implementations of liquid metal towards functional sensors and circuits are currently hindered by the lack of a facile and scalable patterning approach. In this study, we report a fully solution-based process to generate patterned features of the liquid metal conductor. The entire process is carried out under ambient conditions and is generally compatible with various elastomeric substrates. The as-prepared liquid metal feature exhibits high resolution (100 μm), excellent electrical conductivity (4.15 × 104S cm−1), ultrahigh stretchability (1000% tensile strain), and mechanical durability. The practical suitability is demonstrated by the heterogeneous integration of light-emitting diode (LED) chips with liquid metal interconnects for a stretchable and wearable LED array. The solution-based technique reported here is the enabler for the facile patterning of liquid metal features at low cost, which may find a broad range of applications in emerging fields of epidermal sensors, wearable heaters, advanced prosthetics, and soft robotics.

TL;DR: In this paper, the marker and cell (MAC) technique was used to predict the flow of molten metal into casting moulds. And the authors used this technique to model the filling of castings.
Abstract: A computational fluid dynamics technique, termed the marker and cell (MAC) technique, and its derivatives, developed at the Los Alamos Scientific Laboratory, NM, USA, initially for nuclear engineering applications, was found to be very useful in predicting the flow of molten metal into casting moulds. The technique allows the evolution of the molten metal domain, as well as the velocity profile and pressure distribution within the molten metal, to be computed. Coupled with the energy equation, the complete thermal history of the molten metal can then be predicted. The present study was conducted to adapt and modify the MAC technique to model the filling of castings. The modifications include those boundary conditions which match the actual casting operation more closely and those numerical procedures which alleviate the problem of numerical stability and reduce the load of computation. The suitability and accuracy of the model was validated by comparisons with high speed motion pictures of water e...
