The general and galvanic corrosion of high strength steel (980), high strength steel (907) and high strength steel (921A) in seawater at elevated temperatures has been analyzed using electrochemical measurements and a zero-resistance ammeter (ZRA). After the tests, the surface morphologies of the samples have been detected by SEM. Results show galvanic corrosion behavior of 980/907/921A fulfill...

Introduction Human multimodal vestibular cortical regions are bilaterally anterior insulae and posterior opercula, where characteristic vestibular-related cortical potentials were previously reported under acoustic otolith stimulation. Galvanic vestibular stimulation likely influences semicircular canals preferentially. Galvanic stimulation was compared to previously established data under acou...

The galvanic corrosion behavior of Alloy 690 coupled with magnetite has been investigated in an alkaline solution at 30 °C and 60 °C using a potentiodynamic polarization method and a zero resistance ammeter. The positive current values were recorded in the galvanic couple and the corrosion potential of Alloy 690 was relatively lower. These results indicate that Alloy 690 behaves as the anode of...

Cannulated screws, along with guide wires, are typically used for surgical fracture treatment in cancellous bone. Breakage or bending deformation of the guide wire is a clinical concern. Mechanically superior guide wires made of Co-Cr alloys such as MP35N and L605 may reduce the occurrence of mechanical failures when used in combination with conventional (316L stainless steel) cannulated screws...

Photoelectrochemical Water Splitting In article number 2201106, Athanasios Chatzitakis and co-workers combine in situ metal exsolution the galvanic replacement reaction for synthesis of advanced catalysts diverse energy conversion applications. Exsolved Ni nanoparticles are galvanically restructured a wealth bimetallic nanostructures facilely synthesized. Among them well adhered supported AuNi ...

To determine whether subjects with somatosensory loss show a compensatory increase in sensitivity to vestibular stimulation, we compared the amplitude of postural lean in response to four different intensities of bipolar galvanic stimulation in subjects with diabetic peripheral neuropathy (PNP) and age-matched control subjects. To determine whether healthy and neuropathic subjects show similar ...

Dendritic Ag/Au bimetallic nanostructures have been synthesized via a galvanic replacement reaction (GRR) of Ag dendrites in a chlorauric acid (HAuCl4) solution. After short periods of time, one obtains structures with protruding flakes; these will mature into very porous structures with little Ag left over. The morphological, compositional, and crystal structural changes involved with reaction...
