Inhibition effects of ionic and non-ionic derivatives of imidazole compounds on hydrogen permeation during carbon steel pickling
(2022-01-01)
Hydrogen embrittlement can occur when atomic hydrogen is absorbed by steel during the acid cleaning process. In the literature, studies of corrosion inhibition by organic compounds in acid solutions have not given attention ...
Hydrogen permeation and surface properties of PdAu and PdAgAu membranes in the presence of CO, CO2 and H2S
(Elsevier Science, 2018-10-01)
Using the electroless deposition technique with different deposition sequences, it was possible to obtain a single phase PdAgAu ternary alloy after treatment at 773 K during 7 days. Despite the order of deposition, the ...
Modulatory mechanisms of neuronal gap junctions: the role of intracellular hydrogen and magnesium ions in voltagesensitive gating
(2014)
Electrical synapses formed by connexin-based gap junction (GJ) channels are widely
expressed in the mammalian CNS and are essential for the formation of dynamic cellular
networks that allow activity coordination for ...
