Laser-Engraved Micro-Patterned rGO/WPU Composite Structures for Aircraft Applications: Synchronizing Electrothermal De-Icing and Broadband Microwave Transparency. [PDF]
Adv Sci (Weinh)While conventional electrothermal materials tend to reflect electromagnetic waves during de‐icing. Inspired by the frequency‐selective surface theory, this paper designs NJPS for rGO/WPU electrothermal coatings based on the traditional Jerusalem structure.

Biomedicines, 2023 The lunar dust problem was first formulated in 1969 with NASA’s first successful mission to land a human being on the surface of the Moon. Subsequent Apollo missions failed to keep the dust at bay, so exposure to the dust was unavoidable. In 1972, Harrison Schmitt suffered a brief sneezing attack, red eyes, an itchy throat, and congested sinuses in ...

Multiscale Fusion Network Based on Global Weighting for Hyperspectral Feature Selection
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Feature selection (FS) is an important way to achieve high-precision and efficient classification of hyperspectral remote sensing images. However, most existing FS methods use a fixed scale to extract features and the relationship between spatial and ...
