The focusing of electric current by a single p-n junction in graphene is theoretically predicted. Precise focusing may be achieved by fine-tuning the densities of carriers on the n- and p-sides of the junction to equal values. This finding may be useful for the engineering of electronic lenses and focused beam splitters using gate-controlled n-p-n junctions in graphene-based transistors.

Abstract- In a typical competitive electricity market, a large number of short-term and long-term contracts are set on basis of energy price by an Independent System Operator (ISO). Under such circumstances, accurate electricity price forecasting can play a significant role in improving the more reasonable bidding strategies adopted by the electricity market participants. So, they cannot only r...

under the smart grid environments, demand response resources (drrs) as power system resources can effectively participate in and improve performance of electric systems. congestion management is one of the technical challenges in which drrs can play a significant role. previously, congestion management is applied without considering the power system uncertainties. therefore, a stochastic conges...

the effect of cocl2 as an ethylene synthesis inhibitor on changes of protein pattern was investigated in potato (solanum tuberosum l.) plants cultivar white desiree. in vitro grown plants were subjected to ms medium containing 0, 5, 10, 15, 20, 30, 40 and 60 mg/l cocl2 for 4 weeks. different concentrations of cocl2 showed significant effect on the total soluble proteins. among different concent...
