Updated database, new empirical and theoretical values of average L shell fluorescence yields of elements with 23 <= Z <= 96
(Pergamon-Elsevier Science Ltd, 2020)
In this paper, a summary of existing experimental data published in the period of time between 1954 and 2015 is reviewed and presented in a tabular form for average L shell fluorescence yields taken from different sources. ...
Bandwidth Improvement in Bow-Tie Microstrip Antennas: The Effect of Substrate Type and Design Dimensions
(Mdpi, 2020)
In this work, the impact of substrate type and design dimensions on bow-tie microstrip antenna performance and bandwidth improvement is presented both numerically and experimentally at 4-8 GHz. The finite integration ...
Enhancement of image quality by using metamaterial inspired energy harvester
(Elsevier, 2020)
Metamaterial energy harvester based subwavelength imaging structure is presented. Besides, 2x2 array patch antenna is designed to create incident radiated signal towards the proposed harvester structure. Harvested energy ...
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
(Mdpi, 2020)
In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ...
Iron oxide-Si nanoparticle magnetic core-shell induced by the interaction of d-orbitals of Fe2+ with reconstructed Si dimer-like defects
(American Institute of Physics Inc., 2020)
Redox-type charge exchange between Si nanoparticles and aqueous metal ions m(x+) was recently used to synthesize core-shell nanocomposites in which their functionalities have been integrated. The process requires the ...
Experimental and Numerical Investigation of 3D Dam-Break Wave Propagation in an Enclosed Domain with Dry and Wet Bottom
(MDPI, 2021)
Dam-break flood waves represent a severe threat to people and properties located in downstream regions. Although dam failure has been among the main subjects investigated in academia, little effort has been made toward ...
Dynamic transition of nanosilicon from indirect to direct-like nature by strain-induced structural relaxation
(AIP Advances, 2021)
Silicon nanoclusters exhibit light emission with direct-like ns-mu s time dynamics; however, they show variable synthesis and structure, optical, and electronic characteristics. The widely adopted model is a core-shell in ...
An ultrathin and dual band metamaterial perfect absorber based on ZnSe for the polarization-independent in terahertz range
(Elsevier, 2021)
In this work, a new metamaterial design is proposed to yield an ultra-thin and dual band metamaterials perfect absorber (MPA) to be operated in the frequency range from 15 to 35 THz. The proposed structure is consisted of ...
Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
(American Institute of Physics Inc., 2021)
Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ...
Tuning thermoelectric properties of Bi2Ca2Co2Oy through K doping and laser floating zone processing
(Elsevier, 2021)
In the present study, thermoelectric Bi2Ca2-xKxCo2Oy ceramic materials (x = 0.0, 0.05, 0.075, 0.10, and 0.125) in different forms (called bulk, as-grown and annealed fibers) have been manufactured via a classical solid-state ...
