in the present study, we investigate dc conduction mechanism of electron beam evaporated bromoaluminium phthalocyanine (bralpc) thin films using aluminum and gold electrodes. the current-voltage characteristics of sandwich type device are evaluated for the temperature range 298-413k under dark conditions. it is observed that the current passing through the device is increased by increasing te...
Microbial fuel cells (MFCs) are processes used for simultanuous bioenergy capturing and waste treatment. In this study, a model for MFCs based upon a conduction mechanism for electron transfer is proposed, which integrates substrate utilization, current production and conduction and microbial distribution and growth in batch flow mode. The outputs of the model and that of a mediator based mode...
Interest in the P3HT: ZnS nanocomposites are increased due to their applicability as an active layer for bulk heterojunction solar cells of high open circuit voltage and charge transport in this type of solar cells determines their performance. So the study of the conduction mechanism of the P3HT:ZnS nanocomposites is significant to improve the efficiency of such solar cells, and this paper dis...
Electrical conduction anomaly was observed in the mixed ion-polaron regime for xAg2O-40TeO2-(60-x)V2O5 glassy system with 0 ≤x≤ 50 mol%, which were prepared by common melt quenching method. For the understudied glasses, the temperature dependence of dc electrical conductivity was measured from a characteristic temperature to 380 K, which certified their semiconducting nature. The measured condu...
CFTR: Mechanism of Anion Conduction. Physiol. Rev. 79, Suppl.: S47-S75, 1999. - The purpose of this review is to collect together the results of recent investigations of anion conductance by the cystic fibrosis transmembrane conductance regulator along with some of the basic background that is a prerequisite for developing some physical picture of the conduction process. The review begins with ...
Potentials recorded at various sites in the atrioventricular (A-V) conduction system indicate that conduction is continuously electrical in nature and involves no synapse-like (i.e., chemical) conduction. The region between atrium and atrioventricular node has the slowest conduction velocity (.05 M./see.) and lowest safety factor. Conduction through the A-V node is at about .12 M./sec. Results ...
