We study one-, two-, three-, four-, and five-photon absorption of three centrosymmetric molecules using density functional theory. These calculations are the first ab initio calculations of five-photon absorption. Even- and odd-order absorption processes show different trends in the absorption cross sections. The behavior of all even- and odd-photon absorption properties shows a semiquantitativ...
electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...
load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...
In this work we demonstrate optical trapping and manipulation of microparticles suspended in water due to laser-induced convection currents. Convection currents are generated due to laser light absorption in an hydrogenated amorphous silicon (a:Si-H) thin film. The particles are dragged towards the beam's center by the convection currents (Stokes drag force) allowing trapping with powers as low...
The carrier distribution in the interior of power devices can be determined from free carrier absorption measurements. In this work, a physically rigorous simulation of the entire measurement process is performed to investigate the effects which arise from the wave propagation of the probing beam and the sample preparation. Quantitative results for the optimization of the optical setup and the ...
This research analyzes an integrated refrigeration system including a microturbine, a compression chiller and an absorption chiller. The power from the microturbine utilized in the compression chiller compressor, air fans and absorption chiller pump and the waste heat from the exhaust operates the absorption chiller. Four various integrated configuration of the compression and absorption cycles...
Using the S1/2Fg = 2 −→ P3/2Fe = 3 transition in Rb, we analyzed the interaction between the arbitrarily polarized laser light and Zeeman sublevels in the Hanle configuration. We studied theoretically and confirmed experimentally that the effect of the laser light polarization on the electromagnetically induced absorption strongly depends on the laser light power. For the same atomic transition...
in this study, for increasing absorption of the active layer in bulk hetero junction (bhj) organic solar cells (oscs) we used surface plasmon effects of metal nano particles (mnps). we embedded the mnps inside the active layer and studied the device structure. for shown the results we investigated the model of our structure with finite difference time domain (fdtd) numerical method and achieved...
