while a secondary battery cell can provide electrical energy during discharge and then be restored to its original charged condition through an electric current flowing in the opposite direction of discharge (i.e., charge) [2]. Thus, secondary batteries ...
Kinetic energy: The capability of delivering kinetic energy of the crystals was estimated by moving a micron-sized glass bead. The mass of the crystal shown in Fig. 5 and in Supplementary Movie 3 was ~2.5 µg, which was calculated from the relative molecular mass and the size of the ...
