The pathway of formic acid electrooxidation strongly depends on the amount of three neighbouring Pt or Pd atoms in the surface of Pd- or Pt-based catalysts. Here, Pt decorated Pd/C nanoparticles (the optimal atomic ratio, Pd : Pt = 20 : 1) were designed and then synthesized through a facile galvanic replacement reaction where the amount of three neighbouring Pt or Pd atoms markedly decreased. A...

A novel branch-trunk Ag hierarchical nanostructure was synthesized via a galvanic replacement reaction combined with microwave-assisted synthesis using Te nanowire as a sacrificial template. The Te nanowire was synthesized via a hydrothermal process. We further investigated the potential application of the obtained hierarchical nanostructures in electrochemical sensor analysis. The results show...

Pulse rate (PR), blood pressure (BP), auditory reaction time (ART), galvanic skin resistance (GSR), and eosinophil count (EC) were determined in 30 male and 25 female medical students appearing for the I MBBS viva-voce examination. Two readings were taken viz 2 months (control) and 20 min prior to the examination. A statistically significant increase was seen in the PR and BP while a significan...

One of the main sources non-ferrous and precious metals is sulfide ores. This paper presents a review existing literature on electrochemical properties some most common industrial sulfides, such as pentlandite, chalcopyrite, sphalerite, galena, pyrrhotite, pyrite, etc. The study results surface redox transformations minerals, galvanic effect, cathodic oxygen reduction reaction sulfides are pres...

[Purpose] The purpose of this study was to examine the effects of galvanic vestibular stimulation on event-related potentials. [Subjects and Methods] Forty normal female adult subjects were randomly distributed to a galvanic vestibular stimulation application group (20 subjects) and sham group (20 subjects). For galvanic vestibular stimulation application, a positive electrode was applied to th...

[Purpose] This study examined the effects of galvanic vestibular stimulation on motion-related cortical potential. [Subjects and Methods] Fourty healthy female adult subjects each received galvanic vestibular stimulation or sham treatment. For galvanic vestibular stimulation, the anode and cathode were applied to the right and left mastoid processes, respectively, for 10 minutes. Motion-related...

G replacement reactions between solid metal nanoparticles with oxidizing metal precursors represent a versatile strategy for synthesizing hollow metal nanostructures with tailored properties that are difficult (or even impossible) to achieve from their solid counterparts. For example, reactions of silver nanocubes with aqueous solutions of HAuCl4 enable the synthesis of hollow nanoboxes with se...
