Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Light‐Induced Entropy for Secure Vision
Advanced Materials, EarlyView.This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

Riemann tensor of motion vision revisited
Optics Express, 2001 This note shows that the Riemann-space interpretation of motion vision developed by Barth and Watson is neither necessary for their results, nor sufficient to handle an intrinsic coordinate problem. Recasting the Barth-Watson framework as a classical velocity-solver (as in computer vision) solves these problems.

High‐Gain Ag2Te/MoS2 Hybrid Photodetectors for Short‐Wave Infrared Imaging
Advanced Materials, EarlyView.A precision‐engineered short‐wave infrared image sensor based on a 0D/2D Ag2Te/MoS2 hybrid structure is demonstrated in this work. The device exploits photodoping at the nanoscale interface to achieve broadband detection from visible to infrared wavelengths with high responsivity and fast response.

Advanced Materials, EarlyView.This study utilizes the van der Waals stacking of ferroelectric α$\alpha$‐In2Se3 to fabricate in‐plane artificial charged domain walls. These charged domain walls are electrically accessible, gate‐tunable, and show 2–9 orders of magnitude higher conductance than charged domain walls from thin film ferroelectrics, allowing their integration in field ...

Advanced Materials Interfaces, EarlyView.This study reports the first implantable resin cement capable of orientation‐sensitive Magnetic Particle Imaging (MPI). By coating the cement with an ultrathin iron film, the authors achieve a strong, angle‐dependent MPI signal that enables non‐ionizing, real‐time tracking of both implant position and orientation, opening new possibilities for safe ...
