Summary: Combining tumor immunotherapy with nanoparticle-based hyperthermia has been found to enhance cancer treatment effectiveness. Tumor immunotherapy activates the immune system to attack cancer cells, while nanoparticle-based hyperthermia selectively kills cells by raising the temperature of tumor cells. The combination of both approaches can amplify anti-tumor responses, improve outcomes, and reduce side effects.

Summary: Graphene has been widely used as an electrode material for supercapacitors, but the parallel-stacked layers often result in inefficient ion diffusion and electron transfers. By aligning reduced graphene oxide (rGO) using a magnetic field, the electrode showed improved specific capacitance and performance, breaking through the limitations of traditional supercapacitors. This study highlights the potential of aligned rGO to increase the charge/discharge rate and power density of supercapacitors significantly.

Summary: The effects of Sc substitution on metamagnetic transitions for erbium were investigated in order to find optimal magnetocaloric materials for high-efficient magnetic refrigeration. It was observed that the Neel temperature decreased with increasing Sc substitution. The metamagnetic transitions from antiferromagnetic-like to ferromagnetic-like configurations were accompanied by relatively large magnetic entropy changes for all samples. These findings are important for further studies on magnetic refrigeration utilizing the features of metamagnetic transitions.

Summary: We report the thermomagnetic properties of magnetically frustrated A-site spinel magnets, such as CoAl2O4, CoRh2O4, and CoGa2O4, to demonstrate the proximity effects of the Neel-to-spin-spiral (NSS) transition. The magnetic state of CoAl2O4 remains controversial due to its proximity to the NSS transition and sensitivity to crystallographic disorder. The relaxation rate and temperature derivative of thermoremanent magnetization (TRM) were enhanced at the Neel point (T-N) and spin-glass transition temperature (T-SG), and they decayed rapidly above and below the transitions. The relaxation time tau and other characteristic parameters were successfully extracted from the isothermal relaxation of TRM, which was well fitted with a non-exponential relaxation form. The temperature variations of these parameters distinguished the magnetic states for CoRh2O4 and CoGa2O4, while an enhancement of the relaxation rate of TRM was indicated for CoAl2O4 at low temperatures, possibly due to the suppression of long-range antiferromagnetic order.

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.

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.
