a pvc ion-selective membrane electrode based on cd-tetraphenyl porphyrine as a carrier was prepared fordetermination of mno4- ion. this electrode revealed good selectivity toward permanganate ion over a widevariety of anions. effects of some experimental parameters such as nature of the plasticizer, the amounts ofcarrier and additive, and concentration of the internal solution on the potential ...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

A vast selection of different ozone generator designs is commercially available on today’s market. In large-scale applications, the ground electrode is designed as gas/water tube heat exchanger, which is filled with tubular high-voltage electrodes on the gas processing side. Available constructions differ in diameter, length and arrangement of the tubular electrodes, type and support of the die...

Figure 1. Induction of mirror-touch synaesthesia by transcranial electrical stimulation. (A) An incongruent visuo-tactile (VT) trial of the Hand task. The task (~6 min) was to report the site of the actual touch on the hand, while ignoring the viewed touch at the same (Congruent VT) or opposite location (Incongruent VT). In counterbalanced sessions, anodal or sham tDCS (1.5 mA, ~16 min) to S1 o...

• Harvesting energy from light and water drops simultaneously using hidden or transparent front-electrode. Highest photovoltaic performance with surface charge transfer, lowest electrostatic induction electrode. Curved electrodes allow easy removal of drops. Energy harvesting sunlight is often done cells covered by a protective layer polymer glass. Currently, this does not have any other functi...

The paper presented the electrodeposition, morphology and properties of iron deposits were obtained using a low-induction magnetic field 0.001 T in electrocrystallization process. vector induction was directed perpendicular to electrode surface. Iron an electrolyte FeSO4·7H2O – 1.5 mol/l Al2(SO4)3·18H2O 0.15 mol/l. current density 7 A/dm2. Deposits on copper base. influence process electrodepos...

BACKGROUND Dynamic action of anesthetic agents was compared at cortical and subcortical levels during induction of anesthesia. Unconsciousness involved the cortical brain but suppression of movement in response to noxious stimuli was mediated through subcortical structures. METHODS Twenty-five patients with Parkinson disease, previously implanted with a deep-brain stimulation electrode, were ...

BACKGROUND Transcutaneous electrical nerve stimulation (TENS) is a treatment commonly used for managing pain; however, the ideal placement of the electrodes is not fully understood. OBJECTIVE To investigate the best way to apply TENS electrodes in an experimental inflammatory pain model. METHOD Knee joint inflammation was induced in rats, followed by administration of low-frequency TENS (4H...

A novel chemically modified electrode containing Prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. The electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. The film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. Results showed at bare GC electrode, a...
