Summary: Exchange coupling in a model core-shell system is demonstrated as a step towards 3D exchange spring magnets. High-quality core-shell nanoparticles of Ni@CoFe2O4 were fabricated using a simple two-step method. The microstructural quality was validated using TEM, confirming a well-defined interface between the core and the shell. Results showed a strongly temperature-dependent two-phase magnetic hysteresis loop, indicating a coupling of approximately 50% between the core and the shell. Element-specific XMCD hysteresis confirmed the presence of exchange coupling, suppressing the superparamagnetism of the Ni core at room temperature, and achieving a coercivity of >6 kOe at 80 K. These findings provide a pathway for the development of heterostructured metal-oxide exchange-coupled nanoparticles with improved maximum energy product.

Summary: An ultrathin linear-to-linear polarization converter with a high PCR in an ultrawide bandwidth was fabricated. It is based on a bilayer slot structure connected by via holes. The front- and back-sided slot structures, functioning as receivers and radiators respectively, are arranged orthogonally. The via holes transfer electromagnetic energy received by the front-sided slot structures to the back-sided slot structures, resulting in an electromagnetic wave with orthogonal polarization to that of the input wave.

The immobilization of anti-inflammatory cytokine IL-4 on the electrodes successfully induced anti-inflammatory polarization of macrophages, both in vitro and in vivo. These IL-4-immobilized bioelectrodes not only mitigated scarring around the implanted electrodes but also maintained high sensitivity electrocardiogram signals for up to 15 days post-implantation.

Summary: Cellular membrane-derived vesicles (CMVs) have unique advantages as a drug delivery system, but face challenges in yield, stability, and functionalization. This paper introduces three strategies to overcome these limitations: hybrid vesicles of CMVs and synthetic liposomes, core/shell nanostructures with synthetic nanoparticles and cell membrane structures, and CMV/scaffold complexes for sustained release. The authors propose that a combination of hybrid vesicle-coated nanoparticles or hybrid vesicle/scaffold complexes could be a promising drug delivery system.
