Piezoelectricity in Two‐Dimensional Materials
Angewandte Chemie International Edition, 2015 Powering up 2D materials: Recent experimental studies confirmed the existence of piezoelectricity—the conversion of mechanical stress into electricity—in two-dimensional single-layer MoS2 nanosheets. The results represent a milestone towards embedding low-dimensional materials into future disruptive technologies.

Advanced Functional Materials, EarlyView.Two isomorphic COFs were synthesized and compared, including an amphoteric COF (SQ‐TAPT) and a neutral COF (PDA‐TAPT). The ionic bonds in SQ‐TAPT introduce more Born effective charges, thereby enhancing its ionic displacement polarization. Experimental and theoretical calculations demonstrated that SQ‐TAPT exhibited higher polarity and stronger ...

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors
Advanced Functional Materials, EarlyView.We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...
