The influence of pulse magnetic field intensity on the morphology and electrochemical properties of NiCoS alloys

Recent developments, challenges and future prospects of magnetic field effects in supercapacitors

“…Recently Wang et al reported the magnetic field induced hydrothermal synthesis of a NiCoS ternary metal alloy based supercapacitor electrode. 99 The group has used a periodically varying pulsed magnetic field as the magnetic environment during the synthesis. Because a higher magnetic field may boost the nucleation rate, pulsed magnetic fields could provide a very strong instantaneous magnetic strength during the magnetic field “on” time, causing grain refining.…”

“…7h and i). 99 In an interesting study, Wang et al prepared a 2D/2D 1T-MoS 2 /Ti 3 C 2 MXene heterostructure using a magnetic field assisted hydrothermal synthesis route. The study showed that a magnetic field strength of 9 T can transform 2H-MoS 2 into 1T-MoS 2 under similar reaction conditions (Fig.…”

Effect of Wide-Spectrum Pulsed Magnetic Field on Solidification Structure of Pure Al at Constant Flow Velocity

“…Application of a pulsed electromagnetic field can refine the metal solidification structure and is an effective means to improve composition heterogeneity due to forced cooling during the casting process. Pulsed magnetic field fine-grain technology [1][2][3][4][5][6] has gradually attracted people's attention due to its low energy consumption, remarkable effect, convenient application, strong universality and, at the same time, its ability to ensure the cleanliness of metals. Zi Bingtao et al [7] studied the effect of both pulsed current and pulsed magnetic fields on the solidification structure of LY12 aluminium alloy and found that the treatment effect of a pulsed magnetic field on LY12 aluminium alloy was significantly better than that of pulsed current under the same control conditions.…”
