Summary: This study investigated the glass-forming range, microstructural features, and soft magnetic properties of (Fe(1-x-)yCo(x)Ni(y))(86)B-14 alloys. It was found that Fe-rich compositions have the largest glass-forming range and exhibit nano-scale grains with bcc and fcc structures after ultra-rapid annealing. The coercivity and saturation magnetic polarization of the nanocrystalline alloys are affected by Co and Ni content, with Co addition generally increasing coercivity and saturation magnetic polarization, while Ni addition has the opposite effect.

However, in this study, we found the opposite phenomenon in Fe81.3Si4B13Cu1.7 nanocrystalline alloy with pre-existing alpha-Fe nanocrystals. We investigated the structure evolution of melt-spun (Fe, Co, Ni)(81.3)Si4B13Cu1.7 alloys and clarified the related mechanism.

Summary: A new method was proposed to predict the compositions of EHEAs in the Al-Co-Cr-Fe-Ni system, by designing new eutectic or near-eutectic alloys through mixing alloys located on the same eutectic line. Compositional maps were created to show the relations between constituent elements in eutectic alloys, suggesting that EHEAs are derived from binary and ternary eutectic alloys. The proposed diagrams can be considered as convenient methods for evaluating the composition of EHEAs in the Al-Co-Cr-Fe-Ni system.

Summary: The effects of Fe content and annealing temperature on the microstructure, thermal stability, and soft magnetic properties of Fe-rich alloys were investigated. Increasing Fe content up to 85% allowed the formation of a single amorphous phase, but beyond that, crystalline phase appeared. Higher Fe content resulted in a larger crystallization temperature interval, contributing to the process of heat treatment and preparation of amorphous/nanocrystalline soft magnetic materials. The optimum annealing treatment at 430℃ for 10 minutes yielded a high saturation magnetization of 208 emu/g.

Summary: In this study, zinc tungsten oxide nanoparticles (W-ZnO NPs) were synthesized by mixing Na2WO4 and zinc acetate in water, followed by dropwise addition of NaOH. The synthesized composite was characterized using XRD, DLS, SEM, and UV-Vis, and compared with pure synthesized ZnO and WO3 NPs. The non-linear optical properties of the composite were measured using the Z-scan technique with a continuous wave Nd-Yag laser. The results showed a negative non-linear absorption coefficient, indicating saturation absorption in the composite. The decrease in non-linear absorption compared to pure ZnO NPs was attributed to the negligible optical response of WO3 structures, and the negative value of the Z-scan curve suggested thermal lensing effect as the main reason for third-order non-linear refraction.

Summary: In this work, a new dendrimer modified magnetic graphene oxide (GO) was used as a substrate for electrodeposition of Au nanoparticles. The modified magnetic electrode was employed for sensitive measuring of As(III) ion as a well-established human carcinogen. The prepared electrochemical device exhibits excellent activity towards As(III) detection using the square wave anodic stripping voltammetry (SWASV) protocol. At optimum conditions (deposition potential at -0.5 V for 100 s in 0.1 M acetate buffer with pH 5.0), a linear range from 1.0 to 125.0 μgL-1 with a low detection limit (calculated by S/N = 3) of 0.47 μg L-1 was obtained. In addition to the simplicity and sensitivity of the proposed sensor, its high selectivity against some major interfering agents, such as Cu(II) and Hg(II) makes it an appreciable sensing tool for the screening of As(III). In addition, the sensor revealed satisfactory results for detection of As(III) in different water samples, and the accuracy of obtained data were confirmed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) setup. Accounting for the high sensitivity, remarkable selectivity and good reproducibility, the established electrochemical strategy has great potential for analysis of As(III) in environmental matrices.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
