A well-defined test structure of organic static-induction transistor (SIT) having regularly sized nano-apertures in the gate electrode has been fabricated by colloidal lithography using 130-nm-diameter polystyrene spheres as shadow masks during vacuum deposition. Transistor characteristics of individual nano-apertures, namely ‘nano-SIT,’ have been measured using a conductive atomic-force-micros...
a carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . the surface ofthe proposed electrode was characterized by scanning electron microscopy. the presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...
A new method for artificially inducing the cough reflex in the unrestrained and unanesthetized dog has been devised. The present method can be utilized for testing the relative effectiveness of antitussive drugs. A monopolar electrode is in serted into the dog tracheal mucosa in such a way as to minimize surgical stress. The most successful electrical stimulation has been obtained from square-w...
Comprehensive understanding of the ventricular response to shocks is the approach most likely to succeed in reducing defibrillation threshold. We propose a new theory of shock-induced arrhythmogenesis that unifies all known aspects of the response of the heart to monophasic (MS) and biphasic (BS) shocks. The central hypothesis is that submerged "tunnel" propagation of postshock activations thro...
Long-term depression (LTD) is one of the most widely investigated models of the synaptic mechanisms underlying learning and memory. Previous research has shown that induction of LTD in the neocortex decreases measures of pyramidal cell dendritic morphology in both layers III and V. Here, we investigated the effects of LTD induction on 1) the time course of recovery of synaptic efficacy, 2) move...
A conductive metallic particle in a gas-insulated metal-enclosed system can charge through conduction or induction and move between electrodes on insulating surfaces, which may lead to breakdown flashover. The the charging time vary depending spatial electric field intensity, shape, electrode surface coating. charged under influence of field, it discharge become electrically when colliding with...
In this issue, Moliadze and colleagues investigate the role of electrode montage in the induction of acute lasting excitability changes by transcranial Direction Current Stimulation (tDCS) and transcranial Random Noise Stimulation (tRNS); specifically they demonstrate that during weak transcranial electrical stimulation, the position of the ‘‘return” electrode affects neuro-modulation under the...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
abstract wenner direct contact method is a method of estimating apparent electrical conductivity (eca) of agricultural soils in situ. this method can be affected by factors such as quality of electrodes in contact with soil, type of employed electric current, moisture content, clay content and compaction of soil. in this research, the effect of electrode type (rod and plate) and electric curren...
a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...
