Flexible and High‐Performance Perovskite‐Polymer Composites for Dual X‐Ray and Proton Direct Detection

open access: yesAdvanced Optical Materials, EarlyView.
A polymer–perovskite composite obtained by mechanochemical synthesis enables thick, tunable active layers for efficient absorption of highly penetrating ionizing radiation. Vertical‐electrode detectors achieve low X‐ray detection limits and high sensitivity direct 5 MeV proton sensing.

Scalable Task Planning via Large Language Models and Structured World Representations

open access: yesAdvanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...
