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

open access: yesSmall, 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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Spin Wave Electromagnetic Nano‐Antenna Enabled by Tripartite Phonon‐Magnon‐Photon Coupling

open access: yesAdvanced Science, Volume 9, Issue 8, March 15, 2022., 2022
Tripartite phonon‐magnon‐photon coupling in a 2D array of two‐phase multiferroic nanomagnets implements a novel ultra‐sub‐wavelength electromagnetic antenna whose gain and radiation efficiency exceed the theoretical limits for traditional antennas of the same dimensions by many orders of magnitude at some (≈GHz) frequencies.
