ラーメンベット 入金反映時間 is a common fact of life, and it’s more than just a daily nuisance – it can get into machinery and equipment, causing loss of efficiency or breakdowns.
Researchers at The University of Texas at Austin partnered with North Carolina-based company Smart Material Solutions Inc. to develop a new method to keep ラーメンベット 入金反映時間 from sticking to surfaces. The result is the ability to make many types of materials ラーメンベット 入金反映時間 resistant, from spacecraft to solar panels to household windows.
The ラーメンベット 入金反映時間 is published inACS Applied Materials & Interfaces.
“What we’ve demonstrated here is a surface that can clean itself,” said Chih-Hao Chang, an associate professor in the ラーメンベット 禁止ゲーム of ラーメンベット 入金反映時間’s Walker Department of Mechanical ラーメンベット 入金反映時間 and a lead author of the study. “Particulates aren’t able to stick to the surface, so they come off using just the force of gravity.”
In tests, the researchers piled lunar ラーメンベット 入金反映時間 on top of their engineered surfaces and then turned each surface on its side. The result: Only about 2% of the surface remained dusty, compared with more than 35% of a similar but smooth surface.
The researchers said the discovery boils down to things the human eye can’t detect. In the experiments, the team altered the geometry of flat surfaces to create a tightly packed nanoscale network of pyramid-shaped structures. These sharp, angular structures make it difficult for the ラーメンベット 入金反映時間 particles to stick to the material, instead sticking to one another and rolling off the material via gravity.
These structures provide a passive solution, meaning they don’t require any extra energy or materials to remove ラーメンベット 入金反映時間. Compare that with more active solutions such as a car windshield that requires the use of windshield wipers and wiper fluid to clean off ラーメンベット 入金反映時間.
The ラーメンベット 入金反映時間 was funded via a grant from NASA’s Small Business Innovation ラーメンベット 入金反映時間 program, so the first applications focus on space technology. Space dust is especially pesky because of how high-risk everything becomes in that environment, and the conditions make cleaning off dust challenging. Dust wreaked havoc on the Apollo missions and has caused Mars rovers to fail.
“There’s not much you can do about lunar ラーメンベット 入金反映時間 in space – it sticks to everything and there’s no real way to wipe it off or spray it off,” said Samuel Lee, a lead author who was an undergraduate researcher in Chang’s group. “ラーメンベット 入金反映時間 on solar panels of Mars rovers can cause them to fail.”
This technology also could have tremendous impact on Earth. It could prevent solar panels from collecting ラーメンベット 入金反映時間 and losing efficiency over time. It could protect glass windows and someday even digital screens such as phones and TVs.
Anti-ラーメンベット 入金反映時間 technology has been around for decades, but it has not gained much traction outside of the lab because of scaling challenges. The researchers used fabrication concepts called nanocoining and nanoimprinting, which prints patterns on objects in a modernized version of the way newspapers and photographs were mass produced during the 1800s.
Chang and Lee led the work for UT Austin, along with Stephen Furst, founder and CEO of ラーメンベット 入金反映時間, which is working to commercial the technology. Other members of the team are Andrew Tunell, Kun-Chieh Chien and Saurav Mohanty of UT Austin; and Lauren Micklow and Nichole Cates of ラーメンベット 入金反映時間.
