Charge transport in 20–30-Å-thick Bi films is studied by scanning tunneling potentiometry at room temperature. Deposition at T5140 K onto InP-based multilayer substrates leads to flat and continuous films that are subjected to a lateral current density of up to 8310 A/cm. We find that scattering at surface defects and grain boundaries gives rise to discontinuities in the local electrochemical p...
The modulation of the ion-fluxes across a polymeric membrane is important for designing attractive methodologies. As an alternative to commonly used dynamic electrochemistry approaches, light can be as external stimulus and provides very convenient way manipulate ions release and/or extraction into membrane. Herein, we designed solid-contact ion-selective sensor that exhibits response by irradi...
this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
