Summary: In this study, a convenient strategy for fabricating controllable draw ratio of spinel ferrite nanofibres was investigated. The surface topography and draw ratio of the nanofibres can be tuned by adjusting the molarity and polymer concentration of the precursors, calcination temperature and spinning voltage. The magnetic performances of the nanofibres were found to be influenced by the cationic redistribution, which led to an increase in saturation magnetization with increasing calcination temperature. The controllable synthesis strategy and the interpretation of the magnetic properties hold great significance for the application of one-dimensional nanofibres in spintronic and nanomagnetoelectric devices.

Summary: This study successfully fabricated high quality monocrystallite magnetite (Fe3O4) nanorings through a wet and mild-temperature-mediated chemical route, as an alternative to traditional solid-solid annealing methods. It also attempted to fabricate ferrite-based nanorings with different stoichiometry through metal-ion doping and solid-solid reaction by annealing hematite nanorings. The nanoring morphology was confirmed by electron microscopy, and magnetic vortex signature was observed in magnetic hysteresis cycle measurements.

Summary: In this study, a novel core-shell antibacterial agent for water disinfection is presented. The nanocomposite, synthesized by combining quince seed mucilage as the shell material and Fe3O4 as the core material, exhibits enhanced antibacterial activity due to the effective prevention of agglomeration of silver nanoparticles on the shell. The incorporation of magnetic Fe3O4 allows for easy retrieval of the nanocomposites from the medium, enabling their reusability.

Summary: This research analyzes the mechanical properties of electrospun membranes of Polycaprolactone (PCL) loaded with Functionalized Magnetite Nanoparticles (FMNs) at nanoscale spatial domains. The study finds that FMNs have an impact on the crystallinity and melting temperature of PCL. HarmoniX-Atomic Force Microscopy (H-AFM) is used to map the elastic modulus on nanometric domains of the membrane surface, showing that the presence of FMNs affects the local mechanical properties. The distribution of mechanical values is influenced by the filler amount and crystallinity of the fibers hosting the filler, as confirmed by H-AFM analysis.

Summary: Flexible and free-standing electrospun nanofibres are crucial for constructing flexible electrodes and enhancing electrochemical properties in energy storage systems. The demand for flexible batteries has increased with the growth of wearable and flexible devices. Carbon and carbon-derived composites are necessary for the development of flexible and wearable batteries with superior mechanical flexibility, higher energy, and substantial power density. Understanding recent advances in flexible electrospun nanofibres and their synthesis and assembly is essential. This review focuses on the design and merits of various carbon-based nanofibres, including hierarchical, porous, and metal/metal oxide carbon composites, for flexible electrodes.

Summary: Iron oxide nanoparticles with a mean size of approximately 5 nm were synthesized using energetic electrons to irradiate micro-emulsions containing iron salts. The properties of the nanoparticles were investigated using various techniques, revealing that the formation of superparamagnetic nanoparticles starts at a dose of 50 kGy. The particles tend to form clusters and show increasing crystallinity and yield with increasing doses.

Summary: This paper describes a design for a low-cost membraneless water electrolyser using naturally abundant montmorillonite-rich marine mud as a viscous electrolyte to produce green hydrogen. The electrolyte was prepared by resuspending the mud in tap-water and adding NaOH 1 M to enhance the ionic conductivity. Successful separation and collection of hydrogen and oxygen gas was achieved, with the 24% dry mass mud showing stable flow and reliable gas separation. The overall energy efficiency of the electrolysis process was found to be 13% for a current density of 45 mA/cm2. This mud electrolyser shows potential for off-grid, low budget applications with a renewable energy source.

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: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

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.
