Liquid metal brushes for homopolar devices
Design predictions for liquid metal current collectors require a thorough knowledge of liquid metal flows in a narrow gap between a fixed surface and a moving surface, with a strong applied magnetic field and with a free surface beyond each moving end of the gap. The radial and axial velocities in …

The Thermodynamics of Highly Solvated Liquid Metal Solutions
The activity coefficient of magnesium has been measured in the two ternary systems Mg-Sb-Bi and Mg-Pb-Bi with an electromotive force cell at 1073 K. The large negative deviations from ideal mixing behavior that are observed in the limiting binary magnesium systems were found to carry over into the …
