Customizing 3D Polarization Structures at Second Harmonic Frequency

open access: yesLaser &Photonics Reviews, EarlyView.
The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.

Ultralight, Washable, and Antibacterial Ultrafine Fiber Sponges by Direct Electrospinning for High‐Performance Warmth Retention

open access: yesMacromolecular Materials and Engineering, EarlyView.
In this study, a facile approach for fabricating washable and antibacterial PS/PU fibrous sponges by direct electrospinning is demonstrated. The obtained fiber sponge exhibits lightweight (3.89 mg cm−3), significant mechanical durability, warmth retention performance (23.77 mW m−¹ K−¹), and 98.9% antibacterial efficiency after 10 washing cycles, making

Deep learning accelerated the discovery of multi‐principal element alloys with various strength‐toughness trade‐offs

open access: yesMaterials Genome Engineering Advances, EarlyView.
Coupling deep generative models with Pareto optimization, we uncover eight multiprincipal element alloys that outperform existing strength–toughness records after only three design–test cycles, showcasing a rapid data‐efficient route to balanced‐property alloy discovery across high‐dimensional composition spaces.
