Although the bulk is levitated up to high position, the lower electromagnet is continued to operate in continuous levitation using multiple electromagnets.
Continuous levitation was successfully achieved under the desired operating condition.
We are concerned by the continuous reduction in headcount guidance.

The growth velocity is measured for samples processed by the electromagnetic levitation technique using a high-speed video camera.

The levitation force of EDS system is forms by the interaction between the moving magnetic field produced by the onboard levitation magnet and the induced magnetic field produced by eddy current in the ground conductor.
Furthermore, Pt/microporous La2O3 could be one-step prepared by the acoustic levitation method without any pretreatment/modification of raw oxide.
From the HRTEM images, we found that the Pt/porous La2O3 can be still one-step prepared by the simple acoustic levitation method.

They were synthesized by the cold crucible levitation melting technique, and compositions were selected to keep the molybdenum equivalency close to 12 wt% Moeq.
