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 ...
An Innovative Experimental Study on Improving the Rheological Properties of Na-Bentonite Water Based Drilling Muds using Graphene, Graphene Oxide and Graphene Oxide Functionalized with Gold Nanoparticles
(Institute of Physics, 2022)
In this study; it is aimed to improve the rheological properties of Na-Bentonite water based drilling muds (WBDM) by graphene, graphene oxide (GO) and graphene oxide functionalized with gold nanoparticles (AuNPs/GO) at ...
Novel Research on the Use of Multi-Wall Carbon Nanotubes Functionalized with Copper Oxide Nanoparticles in the Adsorptive Desulphurization of Crude Oil: Laboratory Research
(Institute of Physics, 2022)
Crude oil is known as liquid hydrocarbon, which is formed as a result of the metamorphosis of organic matter on earth. Crude oil is a complex mixture containing paraffin, naphthenes, olefins, aromatic compounds and a small ...
A vanadium dioxide-based metamaterial with quatrefoil and circle loaded structure on flexible polyamide substrate for terahertz applications
(Frontiers Media S.A., 2022)
In this study, a novel broadband metamaterial (MTM) absorber is proposed, which is based on vanadium dioxide (VO2) resonators coated onto a flexible polyamide substrate. The VO2 resonator is in the form of a quatrefoil and ...
Boron nitride nanosheet-reinforced WNiCoFeCr high-entropy alloys: the role of B4C on the structural, physical, mechanical, and radiological shielding properties
(Springer, 2022)
The synthesis and extensive characterization of newly developed boron nitride nanosheet (BNNSs)-reinforced WNiCoFeCr high-entropy alloys (HEAs) are presented. The influence of B4C on the structural, physical, mechanical, ...
Investigation of structural, magnetic and microwave absorption properties of NixCo1-xFe2O4/Ni:ZnO (x:0.0, 0.5, and 1.0) embedded epoxy composites
(Springer, 2022)
In this study, NixCo1−xFe2O4/Ni:ZnO (x:0.0, 0.5, and 1.0) epoxy-based composite structures were manufactured by sol–gel method. The structural, morphological and magnetic characteristics were investigated using X-ray ...
Effect of the boriding environment on the wear response of laser-clad AlCoCrFeNi high entropy alloy coatings
(Elsevier, 2022)
Laser-clad AlCrFeCoNi high entropy alloy (HEA) coatings, produced on the surface of AISI 316 L stainless steel, were pack-borided at 1000 °C for 4 h in open air, high-purity Ar and vacuum environments. The HEA, which had ...
