Summary: A series of FeSe0.5Te0.5 bulk samples were prepared using the high gas pressure and high-temperature synthesis method and their superconducting properties were investigated. The results showed that the samples prepared in a Ta-tube had better quality than those without a Ta-tube. The optimized growth conditions resulted in a higher transition temperature (17.3 K) and a higher critical current density (>10(4) A/cm(2)) for the FeSe0.5Te0.5 phase.

Summary: Iron regulation in organisms is primarily controlled by the interaction of the iron-regulatory peptide hormone hepcidin and its receptor ferroportin, which plays a crucial role in maintaining iron homeostasis. Dysregulation of hepcidin can lead to iron overload disorders or iron deficiency, affecting iron delivery and compensatory erythropoiesis.

Summary: Solid polymer electrolytes based on dry poly(ethylene oxide) offer stability, mechanical properties, and flexibility for solid-state lithium batteries. Optimizing ionic conductivity involves understanding the relationship between the electrolyte's nature and architecture and the in-plane ionic transport properties. Different local mechanisms contribute to ionic transport, and distinguishing cationic and anionic mechanisms is necessary. This study determines the in-plane ionic conductivities, transference numbers, and diffusion coefficients of various SPEs and explores their hindered anionic transport.

Summary: The theoretical investigation on the newly synthesized biphenylene network (BPN) monolayer with alkaline metal adatoms reveals that the superconducting critical temperature (Tc) can be increased from 0.03 to 11.22 K by adsorbing Li atoms. This phenomenon is attributed to the enhanced density of states at the Fermi Level, softened vibrations, and electron pockets at the Fermi surface. The diffusion barrier of Li/Na adatoms is very low (<0.25 eV) and tends to decrease at higher coverage. Additionally, the adsorption of alkaline metal atoms significantly enhances the transport anisotropy and the direction with better conductance originates from the connected delocalized multi-center pi bonds. This study highlights the potential of metal atom adsorption for functionalizing BPN monolayers and suggests their future applications in superconducting and electronic devices. Moreover, it emphasizes the importance of carbon monolayer allotropes like BPN monolayer as versatile platforms for both fundamental research and device applications, stimulating explorations in various fields.

Summary: Layered transition metal dichalcogenides (TMDs), specifically MoS2, have been found to have remarkable spintronic properties and can be used as an efficient source of spin current. In this study, the spin-dynamic behavior of MoS2/CoFeB heterostructures was investigated. Raman spectroscopy revealed systematic changes in the characteristic Raman shifts of MoS2 based on the number of layers. Ferromagnetic resonance spectroscopy measurements showed enhanced spin pumping from CoFeB to the MoS2 layer, attributed to the high spin-orbit coupling of monolayer MoS2. The high thermal stability of the sputter grown MoS2/CoFeB heterostructures was demonstrated, making them suitable for spin-orbit torque based magnetic memory applications.

Summary: In this study, it was found that long-term exposure to cadmium leads to decreased iron accumulation in the liver, possibly due to the suppression of iron absorption. The expression of HCP1 and Cybrd1 genes in the proximal duodenum was significantly reduced by cadmium exposure, resulting in reduced iron absorption and accumulation.

Furthermore, a generalized relationship between density and superconducting transport J(c) was established, confirming the positive correlation between rho(core) and J(c).

Summary: The current-voltage (I-V) characteristics of a single-crystalline Bi2223 sub-microbridge with 2.5 unit cells thickness were investigated systematically. The experimental results were well described by the scaling theory for a quasi-2D vortex glass (VG) phase transition, and a phase diagram revealing the VG and vortex liquid phase was constructed. The findings suggest that a high pinning force density may enhance the VG phase transition temperature and suppress the dynamical critical exponent z.

Summary: We report the upper critical field of NbN films in both vertical and parallel orientations, finding that the critical field in the parallel direction exceeds the paramagnetic limiting field, while the perpendicular one approaches it. The temperature dependent perpendicular critical field can be described by the extended Werthamer-Helfand-Hohenberg model considering the Pauli spin paramagnetism. Meanwhile, the parallel data shows two-dimensional superconductivity in the temperature range near the critical temperature. Our results reveal the enhanced Pauli paramagnetic effect with decreasing temperature.

Summary: The density and spatial distribution of dopants play an important role in the properties of TMDCs materials. A phenomenon called concentration phase separation (CPS) is observed where an interface with a steep doping concentration change is formed at high doping concentrations. The difference in the spatial distribution of dopants on both sides of the interface can be identified using various characterization techniques. Understanding these abnormal phenomena is crucial for the design of TMDCs devices.

Summary: To understand the mechanism of high-Tc superconductivity, it is important to reveal the intrinsic properties of the basic superconducting units, such as the single layered FeSe/FeAs in iron-based superconductors or CuO2 planes in cuprate superconductors. In this study, a scanning tunneling microscopy/spectroscopy (STM/STS) was used to investigate the iron-based superconductor KCa2Fe4As4F2. The results showed that a single FeAs layer covered by a reconstructed K surface with an underlying CaF layer exhibited multi-band superconductivity with a lower Tc compared to its bulk counterpart. In regions with scattered K atoms, a pseudogap was observed, indicating an inhomogeneous superconductivity without long-range phase coherence in real space, which is similar to high-Tc cuprate superconductors. These findings provide a new perspective on the origin of superconductivity in iron-based superconductors.

Summary: In this study, the influences of quenching treatment and cobalt-doping on the magnetic vortex dynamics of KCa2(Fe1-xCox)(4)As4F2 (x = 0, 0.1) single crystals were systematically investigated through electrical transport measurements. It was found that cobalt-doping with x = 0.1 can double the slopes of the upper critical field near T-c along both directions. The activation energy and critical current density J(c) were enhanced by the quenching treatment and could be suppressed by the introduction of cobalt-doping. Possible mechanisms for the evolutions of these important parameters were discussed. The results emphasize the important role of quenching treatment in enhancing the activation energy and critical current density in the 12442 system.
