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 ...
Electrochemical α-fetoprotein immunosensor based on Fe3O4NPs@covalent organic framework decorated gold nanoparticles and magnetic nanoparticles including SiO2@TiO2
(Springer, 2022)
The early diagnosis of major diseases such as cancer is typically a major issue for humanity. Human alpha-fetoprotein (AFP) as a sialylated glycoprotein is of approximately 68 kD molecular weight and is considered to be a ...
Effect of Cr Addition on Properties and Tribological Behavior at Elevated Temperature of Boride Layers Grown on Borosintered Powder Metallurgy Alloys
(Korean Institute of Metals and Materials, 2022)
This study focused on chromium addition (0 wt%, 3 wt%, 6 wt%, 9 wt% and 12 wt%) on the boride layer formation, microhardness, fracture toughness and elevated temperature friction and wear behaviour of alloys formed by ...
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 ...
WEDM machining of MoNbTaTiZr refractory high entropy alloy
(Elsevier, 2022)
Refractory high entropy alloys (RHEAs) have shown great promise for a multitude of advanced engineering applications due to their high mechanical stability from cryogenic temperatures to 1600 °C. However, the low ductility ...
Effect of boronizing on microstructure, high-temperature wear and corrosion behavior of additive manufactured Inconel 718
(Elsevier, 2022)
In this study, Ni-based Inconel 718 coatings were additively manufactured on the surface of AISI H13 work tool steel by electro-spark deposition (ESD). Some of the electro-spark deposited samples were boronized at 1000 ? ...
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, ...
Effect of Chemical Composition of Boriding Agent on the Optimization of Surface Hardness and Layer Thickness on AISI 8620 Steel by Solid and Liquid Boriding Processes
(Sciendo, 2022)
Surfaces of cam shafts made of AISI 8620 steels were hardened by boriding processes in both solid and liquid mediums. Various chemical agents were used to achieve boride layers on the surfaces of the cam shafts in these ...
Surface integrity characteristics in wire-EDM of HfTaTiVZr refractory high entropy alloy
(Taylor and Francis Ltd., 2022)
Refractory high entropy alloys (RHEAs) with multiple principal elements constitute a new paradigm in alloy design and have gained recent interest for advanced technical applications due to their unique properties and ...
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 ...
