Summary: This research explores the effects of adding bismuth to Ge20Se80-xBix (0 < x < 12) chalcogenide glasses on their structural and optical properties. The study finds that increasing bismuth content leads to changes in various parameters such as density, molar volume, excess volume, optical bandgap, free volume percentage, and compactness. Monte Carlo technique is employed to evaluate gamma-ray attenuation ability, with the results showing varying trends based on energy levels and optimal shielding properties in samples with x = 10 and x = 12.

Summary: The impact of different amounts of M-type hexaferrite (MH) on the radiation shielding properties of barium titanium (BT) ceramics was investigated. It was found that higher MH content in the ceramics resulted in higher mass attenuation coefficient values, indicating better shielding capabilities against low energy photons. The addition of more MH also led to a thinner shield being needed to attenuate half of the incoming photons. The highest radiation shielding efficiency achieved was 99.836% for BT-MH2 at an energy of 0.05954 MeV.

Summary: The study focuses on the radiation shielding properties of telluro-borate glasses in the (70-x)B2O3-5TeO2-20SrO-5ZnO-xBi2O3 system. The glassy surfaces were confirmed to be amorphous through scanning electron microscope (SEM) analysis, showing no agglomeration. Thermal differential analysis (DTA) revealed a decrease in the glass transition temperature (Tg) from 589.90°C to 529.51°C with the substitution of B2O3 mol% by Bi2O3 mol%. The mechanical properties were evaluated, and the radiation shielding properties were assessed, with the glass containing x 1/4 15% showing the highest effective atomic number (Zeff).

Summary: Microspheres of Ni0.5Co0.5GaxFe2-xO4 (x≤1.0) spinel ferrites (NiCoGaFe-MSFs) and carbon spheres were synthesized via a hydrothermal technique. The microstructure of the microspheres was characterized using SEM, TEM, and XRD. The electrical and dielectric properties of NiCoGaFe-MSF were systematically studied at temperatures ranging from 20 to 120 degrees C (293.1 x 103 to 393.1 x 103) and frequencies up to 3.0 MHz. The results showed that the conductivity, dielectric properties, and impedance spectra of NiCoGaFe-MSFs were influenced by the Ga ion substitution ratios. The formation of semicircles in the impedance spectra was temperature-dependent, indicating a relaxation mechanism. The findings provide valuable insights for the design and application of spinel ferrite-based materials.

Summary: Developing cost-effective and high-performance non-precious electrocatalysts for ORR is crucial for clean energy generation. Single-atom catalysts have shown significantly improved performance, but protecting their structure from deterioration is still a challenge. In this study, a simple strategy for protecting the structure of single-atom catalysts by implanting/decorating FeN4 on Fe-ZIF-derived carbon nanotubes is reported. The developed catalyst exhibits outstanding ORR activity in both acidic and alkaline media compared to commercial Pt/C.

Summary: The addition of BaTiO3 and WO3 nanoparticles has been found to affect the pseudogap and excess conductivity of YBCO polycrystal. The excess conductivity analysis revealed that the experimental data could be described by the 2D Maki-Thompson (MT) and 3D Aslamazov-Larkin (AL) models for samples with low amount of nanoparticles, but the presence of AL contribution and Lawrence-Doniach (LD) models were observed for samples with high amount of nanoparticles. The pseudogap analysis showed an increase in Tpair and a decrease in Delta*(TG) with the addition of nanoparticles.

Summary: This study investigated the electrical and dielectric features for NiCo(NSFs), Pr-NiCo(NSFs), PrY-NiCo(NSFs), and PrYDy-NiCo(NSFs) synthesized hydrothermally. The characterization of the microstructure showed the formation of cubic structure and absence of impurities. The electrical and dielectric measurements revealed the influence of substituted ions on the conductivity and dielectric properties of the samples. Impedance analysis indicated that the conduction mechanism was mainly due to grain-to-grain boundaries. Frequency-dependent dispersion factors were attributed to the conduction mechanism in ferrites.

Summary: The applications of silver nanowires (AgNWs) depend on their purity and morphology. In this study, the morphological changes of AgNWs during growth were tracked to determine the optimal reaction time and temperature. UV-Vis absorption spectra were used to investigate the relationship between reaction time and temperature. An equation was developed to calculate reaction time at any given reaction temperature. The average diameter of the AgNWs was found to be temperature-dependent, with the minimum value observed at a reaction temperature of 150°C. A purification technique was conducted to remove by-products, and an AgNWs-based porous Si device was fabricated and showed high sensitivity and detectivity.

Summary: In this work, a new type of oxygen vacancies and Ti3+ defective perovskite nanostructures (DPNSs) of D-CoTiO3-x were prepared using an eco-friendly sonochemical assisted laser irradiation technique. These DPNSs exhibited excellent electrochemical performance with low over-potential, reduced Tafel slope, high double layer capacitance, large electrochemically active surface area, and exceptional long-term stability. The improved hydrogen evolution efficiency was attributed to the induced synergistic strong metal-support interaction effect of the surface oxygen vacancies and Ti3+ defects in DPNSs, which enhanced conductivity, exposed abundant active sites, increased active surface area, improved kinetics, and facilitated fast charge transport. Furthermore, the DPNSs-based electrode operated through the Volmer-Heyrovsky reaction mechanism and outperformed in terms of electrocatalytic hydrogen activity and stability in natural seawater.

Summary: Understanding the interaction between drugs and nanocarriers is crucial for targeted drug delivery. This study evaluated the release and cytotoxic effects of cisplatin using manganese ferrite impregnated graphene oxide (MnFe2O4/GO) and spherical silica (MnFe2O4/silica). The results showed that both nanocomposites significantly reduced cell viability, with the Pt4+ species of cisplatin on the spinel ferrite/silica nanocomposite having a better cytotoxic effect compared to GO. The mechanism of cell death was found to be apoptosis.
