A Generalized Methodology of Designing 3D SERS Probes with Superior Detection Limit and Uniformity by Maximizing Multiple Coupling Effects

Advanced Science, 2019
Accurate design of high‐performance 3D surface‐enhanced Raman scattering (SERS) probes is the desired target, which is possibly implemented with a prerequisite of quantifying formidable multiple coupling effects involved.

Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet

Advanced Science, EarlyView.
Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...

Unlocking the Full Potential of Jumping Condensation on Microstructured Surfaces

Advanced Science, EarlyView.
Microcone arrays exhibit a spacing‐dependent transition between jumping and non‐jumping condensation. Dense microstructures favor full Cassie droplets, which depart cleanly, while wider spacing favors partial Cassie droplets that retain a localized wet region initiating new nucleation. These findings establish a link between microdroplet morphology and
