Summary: The rheological properties of PFPE oil-based ferrofluids were studied in this research, revealing changes in activity from Newtonian to non-Newtonian to solid-like with increasing w from 10 wt% to 45.5 wt%. The viscosity of the ferrofluids was found to increase with increasing M-w, attributed to entanglements between PFPE oil molecules. The viscosity temperature change in ferrofluids was influenced by both the magnetization temperature variation of Zn-ferrite nanoparticles and viscosity temperature variation of PFPE oil.

Summary: This study investigates the motion of a hydro-ferro-liquid in a rotating and stretching deformed cone. The governing equations of ferrohydrodynamic flow are simplified and dimensionalized using similarity variables for velocity and temperature distribution. The numerical solution of the reduced similarity equations for velocity and temperature is obtained using the finite element technique in COMSOL Multiphysics. The results show that magnetic viscosity is generated in the flow due to the rotation of the cone under the influence of the magnetic field. The study examines the velocity and temperature fields for different parameters and analyzes their effects on local heat transfer and stress on the cone's surface. The findings have practical implications for enhancing the sealing performance of spinning shafts and controlling heat in electronic devices.

Summary: This paper examines the unsteady separated stagnation point flow and thermal progress of Fe3O4-CoFe2O4/H2O on a moving plate, and finds that the magnetic and acceleration parameters enhance skin friction and heat transfer coefficients. However, increasing the heat generation parameter leads to a reduction in the thermal rate distribution, indicating the greater effectiveness of heat absorption compared to heat generation in the thermal flow process.

Summary: The study investigates the effect of magnetic field on laminar forced convection of ferrofluids through numerical simulations. The presence of magnetic field accelerates upstream flow and decelerates downstream flow, disrupting the boundary layers and enhancing heat transfer. The influence of magnetic field depends on Reynolds number and induced magnetic force, with magnetic force dominating at lower Reynolds numbers.

Summary: A numerical study investigated the performance of a triple tube heat exchanger exposed to a uniform magnetic field, finding that swirling flows formed in ferrofluid zones under the magnetic field increased the heat transfer coefficient and slightly increased pumping power. Overall performance was generally improved by the magnetic field, especially when it influenced all flow zones, despite a decrease in second-law efficiency due to increased entropy generation. Additionally, nanoparticle concentration was found to enhance performance index and pumping power.

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.
