Summary: Drug-eluting stents (DESs) are commonly used for the treatment of coronary artery disease. The evolution of the drug-eluting layer on the stent's surface is crucial for its functionality. Using biodegradable polymers is an attractive approach as it reduces the risk of late thrombosis after stent implantation. Understanding drug-release behavior from these polymers is important for improving the safety and efficacy of stent treatments.

Summary: The enhanced awareness of environmental conservation has led researchers to search for alternatives to volatile organic compounds in polymer processing. Ionic liquids have emerged as non-volatile, recyclable, and non-flammable solvents for biodegradable polymers, as well as for the preparation of electrospun fibers. This concise review provides examples of natural and synthetic biodegradable polymers commonly used in electrospinning, and showcases the utilization of ionic liquids in the process. It also demonstrates the preparation of electrospinning solutions using ionic liquids, and presents a concise review of the properties of electrospun biodegradable polymer fibers assisted by different ionic liquids.

Summary: A novel three-dimensional theoretical model of magnetic flux leakage (MFL) is proposed in this paper based on the magnetic dipole model. The model assumes that a uniform magnetization is caused by a uniform external magnetic field around the defect surface of a ferromagnetic specimen. The proposed model provides a better approximation of complex defect shapes than previous models for simple crack defects.

Summary: This study presents a scalable processing technique that integrates multi-walled carbon nanotubes (CNTs) into acrylonitrile butadiene styrene (ABS) polymer using cellulose nanocrystals (CNCs), without the need for functionalization, solvents, or surfactants. The orientation of the nanomaterials and printed road angle was found to greatly influence the mechanical and thermal properties of the composite. Tensile strength and elastic modulus improved by up to 81% and 95% respectively, and interlaminar strength increased by 102%. The thermal conductivity showed an anisotropy between radial and axial directions, with a maximum increase of 807% in the transverse sample. By optimizing print orientation and nanoparticle content, tailored material properties can be achieved.

Summary: The development of biodegradable implants using magnesium alloys faces challenges such as fast degradation, hydrogen gas generation, and pH value elevation in body solution. Surface modification is a practical approach to improve corrosion resistance and enhance bone regeneration and cell attachment. Metal coatings, ceramic coatings, and permanent polymers have been shown to minimize degradation rates, but bioabsorbable polymers are generally preferred for their desired biocompatibility.

Summary: This study investigates how a magnetic field can support local cone growth on a planar electrode during electrodeposition, simplifying fabrication. Magnetic gradient force significantly supports cone growth in addition to the Lorentz force. Nearby cones tend to mitigate the flow driven by the magnetic forces, but the magnetic field still has a beneficial effect on the growth of ferromagnetic conical structures.

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.
