Beta Irradiation Effects on Electrical Characteristics of Graphene-Doped PVA/n-type Si Nanostructures.

This study investigates the beta irradiation's impact on the electrical features of interfacial nanostructures composed of poly(vinyl alcohol) (PVA) doped with graphene. The integration of graphene, a 2D carbon allotrope renowned for its exceptional electrical conductivity, into PVA nanostructures holds significant promise for advanced electronic applications. Beta irradiation, as a controlled method of introducing radiation, offers a unique avenue to modulate the properties of these nanostructures.

Structural and Optical Properties of Interfacial InSe Thin Film.

This study presents a comprehensive investigation of the optical and structural characteristics of the indium selenide (InSe) film prepared on a glass substrate. The structural characteristics of the InSe film were analyzed using characterization techniques including X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy while the UV-vis spectrophotometry method was used in the spectral range between 500 and 1000 nm to examine the optical characteristics. Thus, the UV-vis spectroscopic data were used to extract several optical parameters including extinction coefficient (), optical band gap (), refractive index (), absorption coefficient (α), and optical conductivity (σ).

Natural Radioactivity Levels of the Beach Sands of Cleopatra Beach and Damlatas Beach (Türkiye) and Their Impact on Human Health.

HPGe γ spectrometry method was used to measure the natural radioactivity levels (K, Th, and Ra) of the beach sand samples from Cleopatra Beach and Damlatas Beach in Antalya (Türkiye). The mean K, Th, and Ra radioactivity levels of the studied samples were calculated as 276.88 ± 17.

Microstructural and Radioactive Shielding Analyses of Alumix-231 and Alumix-231 Reinforced with BC/SiC/AlO Particles Produced through Hot Pressing.

AlO, SiC, and BC (10%) particle-reinforced Alumix-231 matrix composites and nonreinforced Alumix-231 blocks were produced by pressing under uniaxial pressure using the powder metallurgy method. The Archimedes density of the produced samples was analyzed using microstructures (SEM and EDS), powder size analysis, and theoretical (PSD software) and experimental methods (Co-60 and Cs-137 radiation sources). As a result of the theoretical and experimental calculations, the Alumix-231 + 10% BC composite material showed the lowest shielding feature against γ radiation, while the Alumix-231 + 10% AlO composite material showed the highest shielding feature.

Electroanalytical Determination of Ziram by Differential Pulse Voltammetry with Reduced Graphene Oxide/Gold Nanoparticles Modified Glassy Carbon Electrode.

The preparation of gold nanoparticles-reduced graphene oxide-based sensor materials for the determination of zinc(II)dimethyldithiocarbamate (ziram) is described in this paper. The graphene oxide (GO) was synthesized using a modified Hummer's method. A composite sensor consisting of gold nanoparticles (AuNPs) and reduced graphene oxide (RGO) was electrochemically fabricated on a glassy carbon electrode.
