Advanced Functional Materials, EarlyView.Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Advanced Functional Materials, EarlyView.Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

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 ...
