Nanowerk April 7, 2024 Magnetic field effects on electrocatalysis have recently gained attention due to the substantial enhancement of the oxygen evolution reaction (OER) on ferromagnetic catalysts. An international team of researchers (Switzerland, Argentina) used a specifically designed magneto-electrochemical system and non-magnetic electrodes to quantify magnetic field effects. They found marginal enhancement in reactions with high reactant availability, such as the OER, whereas substantial boosts exceeding 50% were observed in diffusion limited reactions, exemplified by the oxygen reduction reaction (ORR). According to the researchers their results advanced the fundamental understanding of magnetic fields in electrocatalysis and unveil new prospects for […]

Physicists circumvent centuries-old theory to cancel magnetic fields
Phys.org October 28, 2020 Controlling magnetism, essential for a wide range of technologies, is impaired by the impossibility of generating a maximum of magnetic field in free space. An international team of researchers (Spain, Italy, UK) circumvented the limits to shape magnetic fields by creating a device comprised of a careful arrangement of electrical wires. This creates additional fields that counter act the effects of the unwanted magnetic field. While a similar effect has been achieved at much higher frequencies, this team has achieved the same at low frequencies and static fields—such as biological frequencies—which will unlock a host of useful […]
