Summary: Inflammatory diseases account for 3 out of 5 deaths in the world. Current screening and diagnostic methods are not sufficient in accurately identifying high-risk or low-risk stages of these diseases. In this study, we modified interpolymer complexed superparamagnetic iron oxide nanoparticles (IPC-SPIOs) by incorporating mannose as a targeting biomolecule to improve nanoparticle delivery to M2 macrophages at inflammatory sites. The modified nanoparticles showed increased uptake by M2 macrophages without compromising cellular viability.

Summary: We investigated the effect of different organic coatings on the H-1-NMR relaxation properties of ultra-small iron-oxide-based magnetic nanoparticles. Magnetization measurements revealed similar behavior as a function of temperature and field for nanoparticles with different coatings but the same core diameter. However, the H-1-NMR longitudinal relaxivity showed different intensity and frequency behavior for the smallest particles depending on the kind of coating, indicating different electronic spin dynamics. On the other hand, no differences were found in the relaxivity of the biggest particles when the coating was changed.

Summary: In this perspective article, we review the most significant case studies on magnetic nanoparticles for potential applications in nanomedicine, especially in magnetic resonance imaging. The dependence of the relaxation behavior of magnetic nanoparticles on their chemico-physical properties is discussed in detail. The correlations between the efficiency of magnetic nanoparticles as contrast agents in magnetic resonance imaging and their magnetic core (mainly iron oxides), size and shape, and the coating and solvent used for biocompatibility and dispersibility in physiological media are critically reviewed. Finally, the heuristic model proposed by Roch and coworkers is presented, and its advantages and limitations are highlighted through the analysis of a large amount of experimental data.

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.
