Magnetic noise controlled by electric current through core
Electronics Letters, 1980 Magnetic noise in tape cores can in general be suppressed considerably by passing suitable galvanic currents through them. The method is also applicable to samples subject to asymmetric shear twist forces. A linear decrease in peak-to-peak maximum magnetic noise is observed for increasing currents through the core for the amorphous ribbon Fe80B20.

Controlled motion of electrically neutral microparticles by pulsed direct current [PDF]
Scientific Reports, 2015 AbstractA controlled motion of electrically neutral microparticles in a conductive liquid at high temperatures has not yet been realized under the uniform direct electric current field. We propose a simple method, which employs pulsed direct current to a conductive liquid metal containing low-conductivity objects at high temperature.

Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Relations between ameboid movement and membrane-controlled electrical currents. [PDF]
The Journal of general physiology, 1977 We have studied the pattern of electrical currents through amebas (mainly Chaos chaos) with an ultrasensitive extracellular vibrating probe. Amebas drive both steady currents and current pulses through themselves. Relatively steady current with an average surface density of 0.1-0.2 muA/cm2 enters the rear quarter of an ameba and leaves its pseudopods ...

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
