High-energy incoming photons can be absorbed and concluded to generate Hot Carriers. In normal solar cells, these carriers are scattered by electron–electron electron-lattice mechanisms rapidly lose extra energy approach conduction band edge. This event plus other loss cause that the efficiency of cells limited 33% theoretically. If one makes possibility for extracted rapidly, before scattering...

Wireless power transfer technology via magnetic resonance coupling now has significant interest in industry and research with many applications. This paper proposes a linear multiple transmitter coil array (5 coils) for wireless added gain hence higher efficiency comparison to single coil. The frequency splitting effect as result of the between resonant coils due their close proximity is shown ...

In the present work, radiation properties of a graphene plasmonic patch antenna are investigated and enhanced in terms efficiency, utilizing circuit-matching techniques. Initially, reflection coefficient surface waves due to discontinuities is studied, while power flow towards free-space numerically extracted. This analysis indicates that radiated increased for higher values chemical potential,...

The earliest intense red hue compound of SiO2@LaOF:Eu3+ core-shell nanostructures (NS) was created utilizing a basic solvothermal technique and heat processing. produced particles are spherical, non-agglomerated, have restricted size dispersion. Photoluminescence (PL) radiation spectra exhibit sharp maximums in 593, 611, 650 nm, corresponding with 5D0 -- 7FJ (J=0, 1, 2) Eu3+ conversions. Judd-O...
