Capillary Skimming of Floating Microplastics via a Water-Bridged Ratchet.
Adv Sci (Weinh)
November 2024
Floating microplastics (MPs) have recently become a major concern in marine pollution; however, current filter-based technology is hardly effective for directly removing such MPs from the water surface because of specific mesh size and clogging issues. This paper introduces a new skimming concept for removing floating MPs utilizing capillary force mediated by the elevation of a hydrophilic ratchet at the air-water interface. MPs floating near the ratchet surface are spontaneously forced toward the ratchet with a concave water meniscus, driven by the Cheerios effect.

- A deep learning model was developed to detect and classify cervical cord signal abnormalities, spinal canal, and neural foraminal stenosis on MRI, aimed at improving reporting efficiency and consistency for cervical spondylosis.
- The study analyzed 504 cervical spine MRIs from a patient sample with a mean age of 58, using 90% for training and 10% for internal testing, with additional external testing on another 100 MRIs.
- Results showed the DL model achieved substantial agreement with human readers, outperforming them in classifying spinal canal and foraminal stenosis, and exhibited a high recall of 92.3% for cord signal abnormalities, demonstrating its potential effectiveness in clinical practice.
