For decreasing the amount of air pollution and green gas emission and saving fossil fuels resource, one of the ways is extending renewable energy utilization. Hence, this yields to growth and development of Photovoltaic systems. Nowadays due to increasing electrical energy requirements and ability to privately providing required energy, the use of solar energy and its electrical power creativit...

Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...

Background and purpose: Microbial electro-Fenton system as a novel technology can be employed in removal of resistant organic pollutants along with generation of renewable electrical energy through the activity of anaerobic microorganisms. This study aimed at investigating the performance of this process in treatment of synthetic wastewater containing tetracycline and generation of electricity ...

abstract: electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward pyrrole (c5h6n) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of pyrrole on the pristine nanotubes is a bout -16.37kcal/mol. but when nanotube have been doped with si and al atomes, the adsorption energy of pyrro...

Issues related to environment are one of the most important issues that confront communities in recent decades.   Resource scarcity and the necessity of development for Iran and other similar countries requires us to deal with carbon dioxide emissions as a manifestation of environmental crisis. In this study, we assess the relationship between carbon dioxide emissions as a dependent variable wi...
