The pulsed current has been proposed as a promising battery charging technique to improve the performance and maximize lifetime for lithium-ion (Li-ion) batteries. However, effect of is inconclusive due changeable mode conditions. This article systematically investigates various modes, i.e., positive mode, current-constant negative alternating sinusoidal-ripple on performance. Moreover, compreh...

The paper presents the results of studying phase composition iron-nickel alloys obtained by unsteady electrolysis. It was found that use a unipolar pulse current leads to significant increase in crystallization overvoltage at front moment action, which affects component coatings. formed cathode differs from shown equilibrium diagram.

Multilayer nanowires tailored with alternating AuFe porous layers and Au nonporous segments were fabricated by galvanic square-wave pulsed electrodeposition from a AuFe cyanide-free electrolyte. Control of porosity and composition was achieved via modulation in pulsed time and applied current density. Nanowires with decreased porosity were observed upon increasing time of the AuFe alloy layer o...

Electric discharge machining (EDM) is a ‘newer technology utilized to machine hard metals, alloys, composites and ceramics. This paper reports the experimental investigation carried out on EDM to study the effects of machining parameters such as pulsed current on material removal rate, depth of cut, overcut, tool wear (net weight lost) and hardness on En-31 tool steel The work material was elec...

Electric current-induced phase alternations have been imaged by fast magnetic resonance image (MRI) technology. We measured the magnetic resonance phase images induced by pulsed current stimulation from a phantom and detected its sensitivity. The pulsed current-induced phase image demonstrated the feasibility to detect phase changes of the proton magnetic resonance signal that could mimic neuro...
