Magnetic field enhancement of electrochemical hydrogen evolution reaction probed by magneto-optics

چکیده
External magnetic fields affect various electrochemical processes and can be used to enhance the efficiency of water splitting reaction. However, driving forces behind this effect are poorly understood due analytical challenges available interface-sensitive techniques. Here, we present a set-up based on magneto- electro-optical probing, which allows juxtapose properties electrode with current densities in situ at applied potentials fields. On example an archetypal hydrogen evolution catalyst, Pt (in form Co/Pt superlattice), provide evidence that field acts double layer affecting local concentration gradient hydroxide ions, simultaneously affects magneto-optical magnetocurrent response. • Magnetic effects probed by magneto-optics. Pt. The is linked changes layer.

Enhancement of Bone Healing by Static Magnetic Field in the Dog: Biomechanical Study
Objective- Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF)have been well demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study,effects of SMFs on clinical and biomechanical aspects of bone healing using a canine unstable osteotomygap model were investigated .Design- Prospective descriptive trial.Animals- Fifteen mongre...

Organic molecular FETs provide an experimental framework for studying the band-filling dependent properties of two-dimensional metals. Here, we propose experiments to investigate the band-filling dependent cyclotron resonance, and the effect of van Hove singularities.
متن کاملPurcell magneto-elastic swimmer controlled by an external magnetic field
This paper focuses on the mechanism of propulsion of a Purcell swimmer whose segments are magnetized and react to an external magnetic field applied into the fluid. By an asymptotic analysis, we prove that it is possible to steer the swimmer along a chosen direction when the control functions are prescribed as an oscillating field. Moreover, we discuss what are the main obstructions to overcome...
