In this paper, the interdisciplinary energy harvesting issues on piezoelectric energy harvesting were investigated using a ‘33’ mode (mechanical stress and/or electric field are in parallel to the polarization direction) lead zirconate titanate multilayer piezoelectric stack (PZT-Stack). Key energy harvesting characteristics including the generated electrical energy/power in the PZT-Stack, the ...

Nowadays, energy plays an important role in the economic and community development of country. Consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. Among the different power generation technologies, steam power plants make a significant contribution to power generation in Iran, with a share of 47 % of electricity g...

Electrical consumption in a household is not stable but changeable in one day throughout a whole year. The consumption depends onweather, seasons and users. This characteristic of demand makes it difficult to design and build a distributed power generation system to meet the demand for a household. For this reason, a stand-alone distributed power generation system (DPGS) needs to be carefully d...

Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward hydroquinone (C6H4(OH)2) 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 hydroquinone on the pristine nanotube is  a bout -7.77kcal/mol. But when nanotubes have been doped with Si and Al atomes, the adsorption energy of hy...
