We present here the first room-temperature 2D electronic spectroscopy study of energy transfer in the plant light-harvesting complex II, LHCII. Two-dimensional electronic spectroscopy has been used to study energy transfer dynamics in LHCII trimers from the chlorophyll b Qy band to the chlorophyll a Qy band. Observing cross-peak regions corresponding to couplings between different excitonic sta...

This paper presents an overview of the Ocean wave kinetic energy harvesting system. Energy harvesting is a concept by which energy is captured, stored, and utilized using various sources by employing interfaces, storage devices, and other units. Ocean wave energy harvesting in which the kinetic and potential energy contained in the natural oscillations of Ocean waves are converted into electric...

Abstract We study the performance of vibrational energy harvesting systems with piezoelectric and magnetic inductive transducers, assuming power external disturbance concentrated around a specific frequency. Both linear nonlinear harvester models are considered. use circuit theory equivalent circuits to show that large improvement in both harvested efficiency is obtained, for systems, through p...

Wireless Sensor node is one of the important technologies for the recent world applications like military, agriculture, health etc. But the major problem associated with these nodes is their battery dependence. The Battery Dependence for such nodes responds to the life time of the complete node.Failure of network due to node failure occurs when the battery completely depleted. To beware from su...
