Summary: Magnetorelaxometry imaging (MRXI) is an effective non-invasive imaging technique for magnetic nanoparticles. The choice of sample plays a crucial role in determining image resolution. This study investigated the relaxation signals of different MNP systems in fluid and immobilized states at room temperature and elevated temperatures, and found that Synomag is the most suitable sample for MRXI due to its consistently high relaxation amplitude.

Summary: We studied the harmonic signals caused by the nonlinear AC magnetization curve of suspended magnetic nanoparticles (MNPs) in solution. Numerical simulations were performed to investigate the dominant relaxation in the AC M-H curve affected by Brownian and Ne'el relaxations. The changes in MNP's behavior from Brownian-dominant to Ne'el-dominant relaxation with increased excitation field amplitude were highlighted. Analytical expressions for the third harmonic signal in both dominant cases were obtained.

Summary: This study aims to understand the heat generation mechanism of Multiwall Carbon Nanotube (MWCNT) and MnFe2O4 nanocomposite in different viscous media under an alternating magnetic field. The results confirm the formation of MnFe2O4 phase and its attachment onto MWCNT. The specific absorption rate (SAR) is found to depend on the viscosity of the medium and the dispersion of the nanocomposite, and dipolar interactions play a role in the relaxation mechanism. In addition, in vitro cytocompatibility tests have been performed.

Summary: Recently, localized magnetic hyperthermia therapy has been extensively studied as an independent or adjunct therapy for treating cancer tumors. The generation of controlled heat by superparamagnetic nanoparticles (SPNPs) plays a key role in this therapy. Colloidal SPNPs produce heat under an alternating magnetic field through an electron magnetic spin relaxation mechanism. The type of dispersant used affects the hydrodynamic volume of SPNPs and their relaxation time, ultimately influencing the efficiency of hyperthermia treatment. This review provides valuable insights for designing and synthesizing new hyperthermia materials in the future.

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: It has been proven that introducing alternating magnetic field (AMF) can effectively enhance the catalytic performance of magnetic nanoparticles (NPs) electrocatalysts. This study proposes a feasible design to confine monodispersed ultra-small NiSe2_X NPs in an amorphous carbon matrix and demonstrates that under AMF, the confined NPs experience spin flips that generate magnetic heating, leading to a significant improvement in hydrogen evolution reaction performance. This work provides new ideas for the preparation of ultra-small monodispersed NPs electrocatalysts that can utilize AMF to enhance catalytic performance, which is crucial for accelerating clean energy production.

Summary: Single Pt atom catalysts with high exposure are key targets to enhance electrocatalytic activity, and PtRu alloy nanoparticles are the most active catalysts for the methanol oxidation reaction. This study demonstrates a process to create single-Pt-atom-on-Ru catalysts by growing and spreading Pt islands on Ru branched nanoparticles. The formation of a stable single atom structure is driven by the formation of strong Pt-Ru bonds and the lowering of the surface energy of the Pt islands, resulting in a high current density and mass activity for the methanol oxidation reaction over time.

Summary: Yttrium iron garnet (YIG) grown by liquid phase epitaxy exhibits unique low-temperature magnetization dynamics, with negligible increase in ferromagnetic resonance linewidth down to 10 K. This is attributed to the absence of rare-earth impurities and the suppression of Gd diffusion from the substrate. Compared to YIG films grown by other deposition methods, liquid phase epitaxy YIG films have a sharper YIG/GGG interface and significantly lower ferromagnetic resonance linewidths below 50 K. These films are ideal for low-temperature experiments/applications that require low magnetic losses.

Summary: This study presents a new synthetic approach to functionalize three-dimensional covalent organic frameworks. Through solid-state linkage transformations, the imine linkages of the framework were reduced to amine linkages, resulting in a more stable material ready for further functionalization. The functionalized COFs were tested for their ability to adsorb perfluoroalkyl substances (PFAS) from water, and it was found that the COF-300-dimethyl, functionalized with dimethylammonium groups, showed significantly improved adsorption performance.

Summary: In this study, the influence of manganese substitution on the saturation magnetization of manganese ferrite nanoparticles was investigated. Computational data showed a positive correlation between manganese content and saturation magnetization, while experimental data exhibited an inverse correlation. XRD and magnetometry results indicated that increasing manganese content led to a decrease in crystallite and magnetic diameter, explaining the loss of magnetization. HRTEM analysis confirmed the presence of manganese substitution induced crystal defects, highlighting the need to find methods to eliminate these defects for more reliable ferrite nanoparticles.

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.
