Magnetic Anisotropy Dominates over Physical and Magnetic Structure in Performance of Magnetic Nanoflowers. [PDF]

Small Struct
Idealized schematics showing example magnetic nanoflower colloidal structures, consistent with the small angle neutron scattering data. The chains increase the overall magnetic anisotropy which controls the MNFs’ effectiveness for magnetic particle imaging and magnetic nanofluid hyperthermia.

Simultaneous Delivery of Doxorubicin and EZH2‐Targeting siRNA by Vortex Magnetic Nanorods Synergistically Improved Anti‐Tumor Efficacy in Triple‐Negative Breast Cancer

Small, Volume 19, Issue 43, October 25, 2023., 2023
A novel nanomedicine is synthesized based on Fe3O4 vortex nanorods loaded with doxorubicin (DOX) and EZH2 siRNAs and coated with a macrophage membrane. It shows a preferential tumor enrichment profile, thus leading to highly efficient drug delivery at the tumor site.

Current‐Induced Reversible Split of Elliptically Distorted Skyrmions in Geometrically Confined Fe3Sn2 Nanotrack

Advanced Science, Volume 10, Issue 9, March 24, 2023., 2023
Current‐driven split and integration of the elliptically distorted skyrmions are realized. At a current density of 3.8 × 1010 A m−2, the elliptical skyrmions split into two circular skyrmions. More importantly, such a transition is reversible, which is beneficial for memory applications. The results establish a viable approach to manipulating skyrmions,

A Dual‐Kinetic Control Strategy for Designing Nano‐Metamaterials: Novel Class of Metamaterials with Both Characteristic and Whole Sizes of Nanoscale

Advanced Science, Volume 10, Issue 4, February 3, 2023., 2023
“Nano‐metamaterials,” a novel class of metamaterials, are introduced, which are rationally designed materials with multilevel microarchitectures and both characteristic sizes and whole sizes at the nanoscale, investing in themselves remarkably unique material properties as compared with conventional nanomaterials.

Spontaneous Topological States and Their Mutual Transformations in a Rare‐Earth Ferrimagnet

Advanced Science, Volume 10, Issue 3, January 25, 2023., 2023
Spontaneous magnetic biskyrmions and successive topological transformation into traditional magnetic bubbles via (bi‐)target bubbles are directly observed in a tetragonal ferrimagnetic crystal DyFe11Ti by changing the temperature using in situ Lorentz transmission electron microscopy.

Active Ferromagnetic Metasurface with Topologically Protected Spin Texture for Spectral Filters

Advanced Functional Materials, Volume 32, Issue 34, August 19, 2022., 2022
Metasurfaces provide control over electromagnetic waves, which goes beyond natural materials. They consist of precisely engineered hybrid materials. By the combination of ferromagnetic nanodisks hosting topologically protected vortex states with a ferrimagnetic thin film, a metasurface is created which shows magnetically switchable microwave filtering ...
