“…The magneto‐hydrodynamic effect on the electrochemical reduction of FMN solution was attenuated in the recessed electrode‐based system, consistent with previous reports [26–32] . When a magnetic field of 1 T was applied parallel to the charge transport direction, the extent of the current change at the recessed Pt foil at −0.75 V versus Ag/AgCl was only 4.4±0.4 %, which was significantly smaller than the current change observed in the non‐recessed Pt wire (34.5±3.8 %) setup at identical experimental conditions (Figure 3 b–d, Figure S3).…”

“…To minimize the Lorentz-force-induced convection inside the cell and decouple the magneto-hydrodynamice ffect and apossible radical-pair effect in the electrochemical reduction of FMN solutions,anew electrochemical system was built inspired by previous studies. [26][27][28][29][30][31][32][33] It has been shown that the macroscopic magneto-hydrodynamic effect is minimized in systems with recessed electrodes when the charge transport direction is parallel to the magnetic field direction. [26][27][28][29][30][31][32] Therefore,t he newly designed cell features ar ecessed cathode and anode to ensure that the charge transport direction is homogeneous and perpendicular to the electrode surface.I no ur system, Pt foils (25 mmt hick) on aluminum current collectors were utilized as ar ecessed cathode and anode,fully covering two circular holes at the sides of the cell.…”

Redox cofactors mediate many enzymatic processes and are increasingly employed in biomedical and energy applications. Exploring the influence of external magnetic fields on redox cofactor chemistry can enhance our understanding of magnetic‐field‐sensitive biological processes and allow the application of magnetic fields to modulate redox reactions involving cofactors. Through a combination of experiments and modeling, we investigate the influence of magnetic fields on electrochemical reactions in redox cofactor solutions. By employing flavin mononucleotide (FMN) cofactor as a model system, we characterize magnetically induced changes in Faradaic currents. We find that radical pair intermediates have negligible influence on current increases in FMN solution upon application of a magnetic field. The dominant mechanism underlying the observed current increases is the magneto‐hydrodynamic effect. We extend our analyses to other diffusion‐limited electrochemical reactions of redox cofactor solutions and arrive at similar conclusions, highlighting the opportunity to use this framework in redox cofactor chemistry.

“…Magnetic fields have been superimposed during electrodeposition process to control the surface morphology and the crystal orientation of deposits [5,15,16]. However, the main disadvantage of metal electrodeposition in the magnetic fields is that the surface morphology and the crystal orientation of deposits could not be easily affected unless both the current density and the magnetic flux density could reach a higher level.…”

“…In other works [37][38][39][40][41], the magnetic field effects on nucleation, growth, texture, phase composition, and morphology of the Co layers have been noticed. It has been shown that a magnetic field applied during the deposition process is responsible for two different effects: first, field gradients attract ferromagnetic and paramagnetic materials and repel diamagnetic ones; second, even in uniform fields, magnetic dipoles and therefore the deposits align to the magnetic field direction [42,43].…”

Superimposed external magnetic fields during electrodeposition process offers the possibility to tailor microstructure and properties of the obtained films in a very efficient, contactless, and easily controllable way, what is caused by so-called magnetohydrodynamic MHD effect. On the other hand, the nonequilibrium state of aselectrodeposited nanocrystalline films provides a strong thermodynamic potential for microstructural transformation. This means that the benefit effect of magneto-electrodeposition on a nanocrystalline film can be completely consumed by a thermal exposure at relatively low temperature. Magnetic field annealing has been confirmed to be useful for tailoring the microstructure of as-deposited nanocrystalline films for their widespread uses.The particular interest of this book Chapter Growth of Co-based magnetic thin films by magnetic fields MF assisted electrodeposition and heat treatment is the finding that the microstructure and magnetic properties of nanocrystalline Co-based alloys and oxides like CoX X= Cu, Ni, NiP, FeO are improved by imposition of MF during elaboration process or post-annealing process. "ccording to the previous study, the targeted scientific activities pay more attention to develop alloys and oxides in nanoscale using pulsed electrodeposition assisted by high magnetic field HMF . Note Since the instantaneous current density during pulse electrodeposition is higher than that during direct current plating, the microstructure of the nano-scale electrodeposits can be more easily controlled by perturbing the desorption/adsorption processes occurring in the pulse electrodeposition process .During the experiment, high magnetic field is an in-situ method for the control of electrodeposition process. The obtained material is then annealed or oxidized after
