Molecular Beam Epitaxy (MBE), one of the most established fabrication process for nanostructures with precise control at atomic level of morphology, thickness and chemical composition, has demonstrated recently extended capabilities for the selfassembly and self organization of low dimensional structures such as Quantum Dots (QD) and Quantum Wires (QW). Its main advantage is the compatibility o...

The lithium-sulfur (Li-S) battery is currently of great interest for the research community. This battery promises with its high theoretical capacity (1675 mA h) and energy density (2600 Wh kg) to be one of the energy storage systems of the future. Impressive advances in capacity improvement and capacity stability have been reported recently, e.g. in [1,2]. Nevertheless, the electrochemical pro...

This study carried out to determine of chemical compositions and nutritive value of five species of range plants in Sistan including Oshnan (Seidlitzia rosmarinus), Rendouk (Salsola yazdiana Assadi), Siyah Shor (Suaeda fruticosa), Shoran (Salsola vermiculata) and Anabasis (Anabasis setifera) by in vitro and in situ techniques. Samples were collected by systematic and random sampling procedure i...

Solid-state lithium batteries (SSLBs) have made significant progress in recent decades response to increasing demands for improved safety and higher energy density. Nonetheless, the current state SSLBs are not suitable wide commercial applications. The low ionic conductivity, dendrites growth, unstable interfaces between solid electrodes electrolytes some of challenges that need be overcome. Th...
