Laboratory Study Of Frequency Dependent Streaming Potentials [PDF]
, 1998 Frequency dependent streaming potentials were measured on a glass capillary, porous filter, and a sample of Boise sandstone. The pore diameters for these three samples range from 1 millimeter to 34 micrometers. The frequencies used in these experiments

Preparation of a Rare Earth Ion Selective Electrode [PDF]
Bulletin of the Chemical Society of Japan, 1979 Abstract A new rare earth-ion selective electrode with a cerium(IV) oxide membrane has been prepared. The electrode was selective for the trivalent rare earths with a slope as great as 58 mV. The electrode was less selective for bi- and quadrivalent cations.

Research on the Interaction Between Multi-Circuit Shared HVDC Grounding Electrodes
南方能源建设, 2023 [Introduction] Unlike the independent grounding electrode, shared earth electrode is connected to multiple DC (Direct Current) systems, and its parameters and operation mode need to be determined by each system connected to it.

Earth-Potential Electrodes in Permafrost and Tundra
ARCTIC, 1958 Describes installation at Point Barrow of two sets of electrodes to obtain earthpotential data for use in ionospheric studies. The first set, installed in a 6 x 6 ft excavation down to permafrost (12 in. in Aug. 1955) was five untreated electrodes, which became useless during the winter with resistances increasing by several orders of magnitude as ...
