Radio-wave shielding behavior of steel structures
(Taylor and Francis, 2021)
The shielding of radio wave by steel-containing structures is desirable for electronics protection but undesirable for telecommunication signal reception. This work investigates the shielding behavior of steel structures ...
Utilization of a triple hexagonal split ring resonator (SRR) based metamaterial sensor for the improved detection of fuel adulteration
(Springer, 2021)
In this work, a triple hexagonal split ring resonator incorporated metamaterial sensor is proposed for the improved detection of fuel adulteration. The proposed metamaterial structure is made of three resonators, acting ...
Synthesis and characterization of nanoparticles reinforced epoxy based advanced radar absorbing composites
(Springer, 2021)
In this study, the structural and magnetic properties of NixCo1-xFe2O4 (0.0 <= x <= 1.0) and ZnO nanoparticles synthesized by the sol-gel method were investigated. The microwave property of the composite structures produced ...
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 ...
Time-thermo-dynamics of anti-Stokes and Stokes scattering and luminescence in 1-nm silicon nanoparticles: Toward an optical nanorefrigerator
(American Institute of Physics Inc., 2022)
The thermodynamics of nanosystems is interesting, as they constitute the transition between the atomistic and solid states. This is empowered by the development of tools to manipulate individual atoms and perform atomistic ...
Study on the Field-Dependent Activation Energy, U(H,T), Upper Critical Field, Hc2(0), and Irreversibility Field, µ0Hirr, Properties of Superconducting Single-Crystal Ag-Added Fe(Se, Te) Alloys
(Springer, 2022)
Superconducting FeTe0.5Se0.5 + Ag single-crystal samples with 0, 1, 2, 3, 4, and 5% Ag concentrations were prepared successfully by the self-flux synthesis method. Structural, electrical transport, and magnetic characterizations, ...
Structural and optical characteristics of antimony selenosulfide thin films prepared by two-step method
(Korean Physical Society, 2022)
Antimony triselenide (Sb2Se3) is one of the most promising absorber material choices among the inorganic semiconductors that has attracted much attention today. However, highest recorded efficiencies for Sb2Se3 solar cells ...
Detailed low temperature studies on thermoelectric performance of K-doped Bi2Ca2Co2Oy ceramics fibers
(Institute of Physics, 2022)
The effect of K substitution for Ca in Bi2Ca2-xKxCo2Oy (x = 0.0, 0.05, 0.075, 0.10, and 0.125) thermoelectric ceramics, produced via laser floating zone (LFZ) method, have been systematically investigated. XRD patterns are ...
