Photonic Metrology with Hierarchic Quantum Frequentist Bounds
Advanced Photonics Research, Volume 6, Issue 12, December 2025.This paper proposes photonic metrology with hierarchical quantum frequentist bounds. The present model tightens the Quantum Cramér‐Rao Bound using a hybrid classical‐quantum framework. The experiment validates the hierarchical frequentist bounds for single‐qubit phase estimation.

Advanced Science, Volume 12, Issue 47, December 18, 2025.This review highlights how carbon nanotube (CNT)–based catalyst designs enhance proton exchange membrane fuel cell (PEMFC) performance by improving interlayer interactions. Vertically aligned CNTs facilitate water management, mass transfer, and electron conduction while promoting effective active sites and reducing interfacial resistance.

Autonomous Sorting of Beads in a 3D Environment Using Levitating Magnetic Microrobots
Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.An untethered, magnetically actuated microrobot autonomously collects, weighs, classifies, and sorts passive particles in 3D environments. The system integrates motion control, trajectory planning, and action scheduling to perform fully automated operations.
