Phys.org  February 22, 2023 Dust accumulation is detrimental to optical elements, electronic devices, and mechanical systems and is a significant problem in space missions and renewable energy deployment. A team of researchers in the US (UT Austin, industry) fabricated and demonstrated antidust nanostructured surfaces that can remove close to 98% of lunar particles solely via gravity. The structures are fabricated using a highly scalable nanocoining and nanoimprint process, where nanostructures with precise geometry and surface properties are patterned on polycarbonate substrates. The dust mitigation properties of the nanostructures were characterized using optical metrology, electron microscopy, and image processing algorithms to […]
