In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...
Kinesin motor proteins execute a variety of intracellular microtubule-based transport functions [1]. Kinesin motor domains contain a catalytic core, which is conserved throughout the kinesin superfamily, followed by a neck region, which is conserved within subfamilies and has been implicated in controlling the direction of motion along a microtubule [2] [3]. Here, we have used mutational analys...
A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...
امروزه آلاینده های موجود در جو زمین به یکی از بزرگترین معظلات بشری تبدیل شده است. یکی از مهمترین منابع آلاینده های محیط زیست خودروها می باشند. به همین دلیل روشهای مختلفی برای کاهش آلاینده ها در خودروها پیشنهاد شده است از جمله این روشها استفاده از کاتالیست کانوتر می باشد. کاتالیست کانورتر در مسیر گازهای خروجی خودرو نصب شده و گازهای آلاینده خروجی از خودرو را به گازهای احتراق کامل تبدیل می کند. در...
Combustion catalysts have been extensively explored to reduce the emission of hydrocarbons that are capable of triggering photochemical smog and greenhouse effect. Palladium as the most active material is widely applied in exhaust catalytic converter and combustion units, but its high capital cost stimulates the tremendous research on non-noble metal candidates. Here we fabricate highly defecti...
This review presents a comprehensive overview of the hierarchical nanostructured materials with either geometry or composition complexity in environmental applications. The hierarchical nanostructures offer advantages of high surface area, synergistic interactions, and multiple functionalities toward water remediation, biosensing, environmental gas sensing and monitoring as well as catalytic ga...
