Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

open access: yesAdvanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Quantifying the Contamination of TESS Ecliptic-plane Light Curves by Minor Planets

open access: yesThe Astronomical Journal
Though missions devoted to time series photometry focus primarily on targets far beyond the solar system, their observations can be contaminated by foreground minor planets, especially near the ecliptic plane, where solar system objects are most ...

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

open access: yesAdvanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...

Integrated photogrammetry and photoclinometry for enhanced 3D surface reconstruction of asteroids

open access: yesAstronomy & Astrophysics
Stereo photogrammetry (SPG) and stereo photoclinometry (SPC) are the main techniques used in the 3D surface reconstruction of asteroids. The SPG approach retrieves accurate 3D geometry with limited spatial resolution, while SPC extracts fine-scale ...
