Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film
Advanced Functional Materials, EarlyView.This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

Wind energy generation by forced vortex shedding
Applied Energy, 2023 Alternating slot-blowing (ASB) on a circular cylinder is used to generate energy from the wind by directly exciting or forcing the vortex shedding instability. Low amplitude excitation produces energetic peaks near the natural vortex shedding frequency, while high amplitude forcing relies on circulation control associated the unsteady Coandă effect to ...

Advanced Functional Materials, EarlyView.There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction
Advanced Functional Materials, EarlyView.X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.
