MIT News December 4, 2024 Anthropogenic methane emissions, particularly from diffuse and dilute sources, pose a significant challenge for oxidation and valorization as existing methane oxidation routes rely on high temperatures or pressures. Researchers at MIT found that the catalytic coupling of alcohol oxidase with the iron-modified ZSM-5 (Fe-ZSM-5) zeolite catalyst, created a tandem methanotrophic system that partially oxidized methane at ambient temperatures and pressures. They showed that methane-to-formaldehyde selectivity could exceed 90% at room temperature. The generated formaldehyde was rapidly incorporated into a growing urea polymer. According to the researchers their work presents a sustainable route for methane oxidation… […]

Anti-dust tech paves way for self-cleaning surfaces
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 […]
