Enhanced rate performance of polypyrrole-coated sulfur/MWCNT cathode material: a kinetic study by electrochemical impedance spectroscopy
Lithium-sulfur batteries have a poor cyclability and inferior rate capability due to the shuttle effect of lithium polysulfides. To solve these problems, a sulfur-coated MWCNT composite (S/MWCNT) was coated wi...

The effect of microwave irradiation time on appearance properties of silver nanoparticles
In this paper, synthesis of silver nanostructures was carried out via microwave (MW) irradiation technique in alcoholic media (polyols vis). When silver nitrate is reduced by ethylene glycol, In the presence o...
