The controllable manipulation of gallium-based liquid metal (LM) droplet presents a promising option toward the goal making fully soft machines, which features an autonomy via external administration apparatus. While most current endeavors mainly concentrate on LM-assisted actuations for robots, it is noteworthy that peculiar behavior and LM circuits thus enabled can be adopted as intelligent e...

Hydrogen gas is generated by the electrolysis of liquid ammonia which has high hydrogen capacity of 17.8 mass%. The metal amides are used as supporting electrolytes to dissolve the amide ion in liquid ammonia. The results presented here indicate that liquid ammonia is promising as an energy medium for hydrogen storage and generation.

Hydrometallurgical facilities processing sulfide based ores produce waste residues in the form of sludges that contain concentrations of metals, as well as metal sulfides. As a part of the waste characterization and risk assessment process, a statistical design of experiment was used to assess the significant factors and interactions in the residue leaching process. Two shake flask experiments,...

We present a novel pneumatic actuation system for generation of liquid metal droplets according to the so-called StarJet method. In contrast to our previous work, the performance of the device has been significantly improved: the maximum droplet generation frequency in continuous mode has been increased to fmax = 11 kHz (formerly fmax = 4 kHz). In addition, the droplet diameter has been reduced...

We present a novel pneumatic actuation system for generation of liquid metal droplets according to the so-called StarJet method. In contrast to our previous work [1, 2], the performance of the device has been significantly improved: The maximum droplet generation frequency in continuous-mode has been increased to fmax_=_11 kHz (formerly fmax_=_4 kHz). In addition, the droplet diameter has been ...
