Summary: This article describes a method for synthesizing monodisperse magnetite microparticles with controllable diameter by adjusting the base concentration of the reaction solution. These microparticles spontaneously form colloidal crystal structures and exhibit Bragg reflection colors under an external magnetic field. The fine control of microparticle diameter and investigation of magneto-optical properties would contribute to the technological developments in full-color reflective displays and sensors.

Summary: Systemic autoimmune and inflammatory diseases are complex and only partially understood, involving abnormalities in various components of the immune system. Antibodies, particularly autoantibodies, play a key role in autoimmunity. The interaction between antibody fragment crystallisable (Fc) and Fc receptors (FcRs) has attracted much attention recently, with potential therapeutic prospects in the future. This review comprehensively describes the roles of known FcRs in systemic autoimmune and inflammatory disorders, including rheumatoid arthritis, Sjögren's syndrome, systemic lupus erythematosus, and other related diseases.

Summary: Shape anisotropy in colloidal zincblende CdSe nanoplatelets directly affects their optical and electronic properties. The lateral aspect ratio of NPLs provides a way to control their optical characteristics, such as polarized emission, by varying the shape while keeping the thickness constant. Experimental and simulation studies have shown that the growth behavior of CdSe NPLs can be altered by adjusting the Cd(ac)(2)-to-Se precursor ratio, leading to different growth directions. The mechanism for the lateral growth of zincblende NPLs has been explained at the atomic level, shedding light on the transition processes of NPL morphology and growth direction.

Summary: The study found that rPoly p 5 does not affect NO production or the expression of co-stimulatory molecules in mouse peritoneal macrophages. However, rPoly p 5 increased IL-1 beta production in non-activated macrophages and decreased TNF-alpha and MCP-1 cytokines production in activated macrophages. The findings suggest an important role of this allergen in modulating M2 macrophage phenotypes, especially in previously activated macrophages.

Summary: The presence of polyphenols in the Passiflora alata Curtis plant gives it antioxidant, anti-inflammatory, and antiproliferative properties. However, depending on their concentration and interaction with other molecules, these polyphenols may also have a pro-oxidant effect. This study evaluated the effects of the aqueous leaf extract of P. alata and its polyphenols on lymphocyte proliferation, viability, cell cycle, and oxidative stress. The results showed that these substances inhibited lymphocyte proliferation, caused cell injury and death.

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.
