In this work, CNTs/MnO2 hybrid supercapacitors were prepared using RF magnetron sputtering as deposition technique. The as-prepared composite materials were characterized by different morphology and spectroscopy techniques, ...

Nowadays, one of the most critical issues in photovoltaic (PV) industry is the fabrication of an efficient and low cost solar cells. The solar energy have to be more efficient and cost effective than other electricity ...

Thermoelectric technology converts thermal energy to electricity. Many studies were conducted on thermoelectric materials such as Bismuth Telluride and Lead Telluride. And the goal was to achieve an average ZT >2 which is ...

The daily increase in the world needs for new sources of energy, the population and economy growth, and the industrial expansions made the demand for new sources of energy a critical request within different societies. ...

A novel catalyst consists of a group of metals (Ni, Co and Cu) deposited on carbon fiber support and was prepared for oxidation using methanol and ethanol in alkaline medium. The carbon fiber support was fabricated by ...
