Summary: This paper presents a study on developing an optimal system for generating a fast-changing rotating magnetic field that leads to the hyperthermic effect in magnetic liquids. The authors used the three-dimensional Finite Element Method (FEM) with a unique dl-T0 formulation to calculate and design the system. The results of the proposed FEM model and developed software were compared to measurements on a specialized test stand, and a prototype of the system was built. The paper also discusses the application of the prototype in investigating the hyperthermic effect in a specific type of magnetic fluid.

Summary: The main idea of magnetic hyperthermia is to locally increase body temperature by means of injected superparamagnetic nanoparticles, absorbing energy from an external magnetic field. The study demonstrates the influence of thermal effects on superlocalization and heating efficiency, showing similarities between deterministic and stochastic results in the presence of time-dependent steady state motions of the magnetization vector. It also highlights the importance of oscillating applied field in low frequency range for hyperthermia.

Summary: In this study, we investigated the synchrotron radiation emitted by a charged fermion in a constant magnetic field parallel to the axis of rotation. The rotation is classical and independent of the magnetic field. We derived the intensity, spectrum, and chirality of the electromagnetic radiation using the exact solution of the Dirac equation. Our numerical calculations demonstrate that the effect of rotation on the radiation intensity increases with the particle energy and can either strongly enhance or suppress the radiation, depending on the relative orientation of the vectors omega and B and the sign of the electric charge.

Summary: This paper presents a new method of generating a high-frequency rotating magnetic field and investigates its influence on energy losses in a magnetic fluid. The results show that the intensity and frequency of the rotating magnetic field have different effects on the temperature rate of change, with the intensity being proportional to the square of the magnetic field strength and the frequency being proportional to its square as well. In the low-intensity region, energy losses are primarily due to magnetic relaxation, which decrease with the increase of magnetic field strength, while losses due to magnetic hysteresis increase. A comparison between rotating and alternating magnetic fields reveals that the rotating field releases 75% more heat energy than the alternating field.

Summary: This study presents theoretical results on the effect of magnetic interparticle interaction on the kinetics of remagnetization in magnetic gels with immobilized single-domain particles. The magnetic anisotropy of the particles is assumed to be very strong, and the particle axis of easy magnetization is randomly oriented. The results demonstrate that the interparticle interaction affects the kinetics of particle remagnetization, with the strength of the applied magnetic field playing a deciding role. Specifically, this interaction slows down the composite remagnetization when the applied magnetic field is weak, but speeds it up when the field is high.

Summary: The article compares two versions of a 3-phase system for generating a rotating high-frequency magnetic field at 100 kHz using rectangular signals with shifted phases. Sinusoidal signals were obtained from square waveforms using passive filters with capacitors and inductors. The delta-system delivered a 72% higher magnetic field strength and more than 3.5 times the temperature increase rate compared to the (Y)-system. The high efficiency of the delta-system makes it suitable for magnetic hyperthermia as a treatment supporting radio- or chemo-therapy.

Summary: The article introduces a new method for generating a high-frequency rotating magnetic field with a measuring system that can be powered by both sinusoidal and square signals, significantly reducing the device cost. The author investigates the conditions for thermal energy release in a magnetic fluid placed in a high-frequency rotating magnetic field, and presents preliminary results on the calorimetric effect of the fluid in both rotating and alternating magnetic fields. The experiments show that the thermal effect in a rotating magnetic field is more than two times greater than in an alternating magnetic field, allowing for a significant reduction in the mass of magnetic material needed for medical applications.

Summary: The behavior of magnetic rod-like particles in alternating and rotating magnetic fields and their relationship with the heat generation effect were investigated through Brownian dynamics simulations. Densely-packed clusters were formed in significantly strong particle-particle interactions, which did not contribute to heat generation. Linear thick chain-like clusters were formed in alternating magnetic fields in the intermediate frequency range, with the constituent rod-like particles rotating to follow the field change. In contrast, linear clusters in rotating fields rotated as a whole body in response to the magnetic field rotation. The magnetic interactions between constituent particles suppressed the relaxational motion of rod-like particles, leading to an increase in the heat generation effect in certain situations. The rotating applied magnetic field had a larger heat generation effect in a relatively large frequency region, while the alternating magnetic field yielded a larger heating effect in the lower frequency region.

Summary: This study presents physico-mathematical models for the cavitation of microbubble clouds during histotripsy, considering bubble-bubble interaction and variable surface tension. The Keller-Miksis equations based on the Neo-Hookean and Quadratic Law Kelvin-Voigt models are transformed into ordinary differential equations using non-dimensional variables and solved analytically. The effects of viscoelastic medium on single microbubble dynamics and interbubble interactions are investigated. The study shows that the growth of a single bubble is more pronounced than the interaction of multiple bubbles, and the number and distance between bubbles play significant roles in the cavitation process during histotripsy of cancerous tissues.

Summary: The paper presents a theoretical study on the circulating flow in a channel filled with a non-magnetic liquid and an injected drop of a soluble ferrofluid under the influence of a uniform rotating magnetic field. The aim of this study is to develop a scientific understanding of drag transport intensification in thrombosed blood vessels. The results demonstrate that under realistic parameters, circulating flow with a velocity of approximately one hundred millimeters per second can be generated in a channel with a thickness of several millimeters. This can significantly enhance molecular transport (thrombolytics) in the channel.

Summary: This study proposes a theoretical model for the dynamic susceptibility and magnetoviscous effect in non-dilute polydisperse ferrofluids with magnetically interacting particles. The system is considered as a homogeneous magnetic colloid without any heterogeneous aggregates. The analysis is based on a mathematically regular approximation of the pair interparticle interaction combined with the effective field method, which agrees well with laboratory and computer experiments in dilute ferrofluids with non-interacting particles and computer simulations of monodisperse ensembles of magnetically interacting ferromagnetic particles.

The models include both single encapsulated microbubbles and interacting microbubbles in lipid shells. The modified Church equations for microbubbles with different shell thickness are analytically solved, and it is found that the radii of outer microbubble dynamics are larger than those of inner radii of encapsulated microbubble dynamics under the effect of layer thickness.

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.
