“…At LSV (linear sweep voltammetry) voltammograms recorded in pH = 0.5 and 3.5, the current density was observed to increase with the increase of magnetic field magnitude in the mass transport regime on the cathodic and anodic branch. Similar requests were obtained in 2007 by Marsushima and coworkers [20]. They investigated copper potentiostatic electrodeposition from 1.85 M H 2 SO 4 and 0.6 M CuSO 4 with a sheet of copper as an anode.…”

“…The second effect that was discovered in the described studies is the change in morphology of the electrodeposits. The deposits of copper are less dendritic under the magnetic field [20], which can be caused the nature of electrochemical process. Dendritic structure is connected with full diffusion-control processes, which means that the structure obtained under magnetic field is due to mixed-control process [25].…”

“…Equations with I L~B b dependence with different values of b were presented for example by Aogaki [28], and others with b values within the range of 0.25 to 1.6 [27]. Recent research on this subject, conducted by Sudibyo and Aziz in 2015 [29] for lead magneto electrodeposition, gave the following equation of limiting current density: Reprinted from [20], with permission from Elsevier where K′ is a constant (and the Faraday constant F is included in K′), C is the concentration of the electroactive species, A is the electrode area, D is the diffusion coefficient of the electroactive species, υ is the kinematic viscosity of the electrolyte, B is the magnetic field strength, and n is the number of electrons of the oxidation-reduction reactions.…”

“…In studies conducted by Matsushima and other scientists in 2007 [20], it was found that the size of copper grains decreases under magnetic field but the influence of intensity of the magnetic field depends on the cathode potential. The morphology of electrodeposits obtained at − 60 mV potential differs from deposits obtained at − 400 mV.…”

“…The effect of magnetic field on copper electrodeposition is noticeable in all papers described above [10,[18][19][20]. In order to investigate the effects of constant magnetic field on the surface morphology of the copper electrodeposited on glassy carbon electrode from CuSO 4 at pH = 0.5 Hinds et al [10] used SEM.…”

The paper presents and summarizes some research on constant magnetic field effects in chemistry. Metals and alloys electrodeposited under constant magnetic field have greater thickness and smoother surface with finest grains. Metallic materials deposited under the influence of uniform magnetic field may have stronger corrosion resistance, than those obtained without the presence of magnetic field. Constant magnetic field also causes an increase of the electropolymerization rate and yield of some organic reactions. Our research also shows that the presence of constant magnetic field affects the electrodeposition process of alloys and their morphology to a great extent. The effects of magnetic field on metals, alloys, composites, polymers and other materials are due to the Lorentz force and the magnetohydrodynamic effect. It is possible that the further development of magnetoelectrodeposition will allow for using the constant magnetic field to improve the properties of metal coatings, alloys, polymers, and other materials in the industry.

SUMMARY This experiment uses nickel electrodes and adds pulse potential and magnetic force when producing hydrogen via water electrolysis and explores how related parameters are affected by magnetohydrodynamics and pulse potential. Experiments showed that the Lorentz force of the magnetic field changes the direction of convective flow of the electrolyte, which affects the flow of bubbles during electrolysis. Adding a magnetic field increases the rate of current density by roughly 15% under a normal temperature, a distance of 2 mm between electrodes and a potential of 4 V. Pulse potential instantaneously increases current and accelerates both the movement of bubbles from the electrode surface and the mass transfer rate in the electrolyte, which lowers electrochemical polarization in the diffussion layer and further increases hydrogen production efficiency. When the duty cycle is 10% and the pulse on‐time is 10 ms, almost 88% of overall power is converted, and current density increases by 680 mA/cm2, which is an increase of roughly 38%. Generally, pulse potential and magnetic field effects enhance each other when added under suitable pulse potential and basic potential. Copyright © 2013 John Wiley & Sons, Ltd.

Low silver contents are desirable for electrically conductive adhesives (ECAs) due to the high cost of silver. In the present work, micron ower-like silver particles (MFSPs) with long and thin petals are prepared by a novel, green, and facile chemical reduction method in an aqueous solution. The effects of reactant mass ratio and reactant concentration are investigated to control the morphology and size of MFSPs. Three kinds of MFSPs with different sizes are lled into an epoxy resin to prepare novel ECAs. Due to the easily formed conductive paths by such morphological silver particles, the prepared MFSP/epoxy composite adhesive has a low percolation threshold, a high conductivity and high adhesion strength at a very low silver content. When considering the optimal combination of low electrical resistance and high adhesion strength, the MFSPs obtained at the 1.5:1 ratio of ascorbic acid to silver nitrate are promising for preparing ECAs with a low Ag content of 30 wt which is the lowest content for ECAs compared with the literature. The synthesis process of MFSPs has the advantages of mild condition, simple process, and environmental friendship. This study provides a new way to prepare highly conductive Ag/epoxy adhesives with low silver contents.
