Corrosion of pipe steels under alternating currents

open access: yesInternational Journal of Electrochemical Science, 2021
The present paper aims to analyze and compare AC interference on pipeline steel grades in soil simulating solutions. DC current density (JDC) and protection potential (PP) are measured to determine AC interference.

Study on the Numerical Simulation of Coupling Interference Law of AC Transmission Lines to Buried Pipelines [PDF]

open access: yesCailiao Baohu
In energy public corridors, the similar routing of AC transmission lines and buried pipelines inevitably causes the pipeline to enter the AC interference zone, leading to pipeline AC corrosion, abnormal cathodic protection systems, and posing a threat to

Experimental demonstration of the time reversal Aharonov-Casher effect [PDF]

open access: yes, 2005
We demonstrate the time reversal Aharonov-Casher (AC) effect in small arrays of mesoscopic semiconductor rings. By using an electrostatic gate we can control the spin precession rate and follow the AC phase over several interference periods. We show that
