Summary: This study presents a method to modify the giant magnetoimpedance (GMI) effect in amorphous glass-coated ferromagnetic Co based microwire reinforced polymer through laser irradiation. By in-situ laser annealing, a 25% improvement in the GMI response is achieved within only 4.9 minutes. This in-situ technique offers a faster and more convenient way to tailor tunable electromagnetic shielding, structurally integrated antennas, and magnetic sensors in multi-functional composites.

Summary: The paper presents experimental results on contactless strain measurement using bistable glass-coated microwires as substitutes for conventional electrical strain gauges. The results show that the microwires can be used as passive elements without physical connection to the sensing unit, and they can effectively measure strain in metallic materials with ferromagnetic nature or in changing magnetic environments. The influence of parasitic external magnetic fields can also be separated during the measurements.

Summary: In this study, the viscoelastic behavior of Teflon fabric-reinforced Nafion (TFRN) membrane was observed after coating with silver, silver with carbon nanotubes, and silver with graphene nanoparticles. The results showed that the coated membranes had enhanced strength and different levels of creep resistance. The addition of graphene nanoparticles resulted in higher strength and lower glass transition temperatures. Differential scanning calorimetry and thermogravimetric analysis were used to characterize the thermal properties of the samples, indicating that they were thermally stable up to 420 degrees C.

Summary: To support the development of smart technology, higher frequencies will be used in 5G and beyond mobile communication systems for the Internet of Things, smart devices, and smart manufacturing. This will lead to an increase in the number and types of network devices and the need to suppress electromagnetic interference in small wireless communication terminals. A noise suppression sheet is developed to minimize electromagnetic interference in the new frequency bands, and a method is created to evaluate its transmission attenuation characteristics up to 60 GHz. The practicality of the sheet is confirmed through measurements of commercially available noise suppression sheets.

Summary: Effective wound management is challenging due to complexity of wound microenvironment, bacterial infections, impaired angiogenesis, aggravated inflammation, and enduring pain. A multifunctional composite hydrogel was developed to address these challenges, comprised of gelatin, chitosan, polydopamine-coated bioactive glass (BG), and curcumin-capped silver nanoparticles (Cur-AgNPs). The PDA-coated BG provides adhesive, angiogenic, and pain-relieving properties, while Cur-AgNPs offer bactericidal and anti-inflammatory benefits. The composite hydrogel showed excellent wound healing potential by alleviating pain, eliminating microbes, reducing inflammation, promoting angiogenesis, and achieving effective skin regeneration.

Summary: This study investigates the effects of annealing conditions and postprocessing treatments on the longitudinal magnetostriction, acoustic noise, and core losses of Fe-based amorphous soft magnetic materials. The results show that higher longitudinal magnetostriction leads to increased acoustic noise emission, while reducing longitudinal magnetostriction can increase core losses. Additionally, bending stress and stress introduced after epoxy impregnation and curing also contribute to increased core losses. Low longitudinal magnetostriction is important for stress insensitivity and soft magnetic properties.

Summary: In the planar flow casting process, the cooling rate plays a significant role in determining the structure and properties of a cast ribbon. By simulating the influence of the thermal conductivity of the cooling wheel substrate, it was found that a higher thermal conductivity leads to a higher cooling rate. The effects of cooling rate on the soft magnetic properties of Fe-Si-B amorphous ribbons were investigated, and it was observed that increasing the thermal conductivity of the cooling wheel substrate resulted in a reduction in coercive force and core losses of the amorphous ribbon.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
