typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...

Energy harvesting from surrounding environment has been attractive for many researchers in recent years. Therefore, developing appropriate test apparatus to study energy harvesting mechanisms and their performance is of paramount importance. Due to their electromechanical characteristics, piezoelectric materials are used for harvesting energy from environmental vibrations. For optimum utili...

The search for environmentally clean energy sources has spawned a wave of research into the use of carbon nanomaterials for photovoltaic applications. In particular, research using semiconducting single-walled carbon nanotubes has undergone dramatic transformations due to the availability of high quality samples through colloidal separation techniques. This has led to breakthrough discoveries o...

Energy harvesting is the process of foraging electrical energy from energy sources available in the environment. This paper reviews energy harvesting technology using PZT as the specific piezoceramic material with its modules to determine the capacitance for optimal energy-storage in piezoelectric vibration energy harvesting (VEH) systems . It reviews various applications of piezoelectric energ...

Energy is everywhere in the environment surrounding us i.e. it is available in the form of thermal energy, light (solar) energy, wind energy, and mechanical energy etc. However, the energy from these sources is often found in such minute quantities that it cannot supply adequate power for any viable purpose. In fact, it has not been possible to capture such energy sufficiently to perform any us...

Electrostatic couplings between chromophores in photosynthetic pigment-protein complexes, and interactions of pigments with the surrounding protein environment, produce a complicated energy landscape of delocalized excited states. The resultant electronic structure absorbs light and gives rise to energy transfer steps that direct the excitation toward a site of charge separation with near unity...
