All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

Advanced Materials, EarlyView.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

Advanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

White‐Light Emission in Zeolitic Imidazolate Framework Glasses

Advanced Materials, EarlyView.
Broadband blue emission is discovered in ZIF‐62 through vitrification and hot‐pressing. This emission is significantly enhanced and redshifted when the ZIF‐62 glass is annealed above the critical temperature (1.07Tg), being attributed to an enhancement of ligand‐to‐ligand charge transfer.

Point Cloud Upsampling for Accurate Surface Reconstruction via Attention-Guided Generation

IEEE Access
Reconstructing accurate surfaces from sparse point clouds remains a fundamental challenge in 3D vision. In this paper, we propose a novel upsampling framework, called Surf-PU, that focuses on surface-aware point generation.
