Omni‐Directional Assembly of 2D Single‐Crystalline Metal Nanosheets
Advanced Materials, EarlyView.A versatile assembly method is developed to uniformly assemble 2D single‐crystal copper nanosheets (Cu NS) onto substrates with complex shapes via ultrasonication process. This technique leverages cavitation effects to deposit monolayer Cu NS films with minimal overlap.

Advanced Materials, Volume 37, Issue 13, April 2, 2025.Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Photon Management on a Photonic Crystal Platform
, 2015 A multilayered dielectric structure, namely a one dimensional photonic crystal (1DPC), is proposed as a suitable platform for photon management, due to the low absorption of the dielectric materials. When properly designed, a 1DPC can sustain surface electromagnetic modes called Bloch Surface Waves (BSWs).

Advanced Materials, EarlyView.A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture
Advanced Materials, EarlyView.Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.
