Scientists have found that polar bears have a natural ice system in their fur and can match the best synthetic anti -dyeing materials, which may provide sustainable solutions to prevent the dangerous ice accumulation on the aircraft wings and wind turbines. These discoveries were published in scientific development, revealing how these Arctic mammals evolved and produced a special oil coating, which was almost free at temperatures as low as -40 ° C.
The research team found that the fur of the bear is similar to the advanced industrial ice -resistant surface, and its effectiveness originated from the unique mixture of natural oil called Sebum. When this protective coating is removed, the ice adhesion intensity of the fur increases by four times, highlighting the key role of these natural compounds.
Use quantum chemical simulation, researchers have determined specific lipids in sebums, and the keys of these lipids and ice are abnormal. What is also interesting is the lack of things-compounds called SPOREENE commonly found in other marine mammals, which are obviously not existing in the fur of the polar bear. This lack seems to be a vital adaptation.
“We find specific lipids in sebum, such as cholesterol and dilate glycerin, showing a very low adsorption energy on ice. This weak interaction is the reason why Ice stuck to the fur.
This discovery has special significance because the industry seeks to replace harmful fluoride -chromatin materials. Studies have shown that unprecedented polar bears are equivalent to these industrial coatings, which shows the way to more environmentally friendly solutions.
SACCHI pointed out: “It is really fascinating to see how to optimize the composition of sebum to avoid ice adhesion.” “We find that in a common lipid in other marine mammals, the fur of the polar bear is almost completely existing at all. . Our calculation simulation shows that the scale rock is strongly adhered to the ice, which significantly enhances the icing of the fur.
The study also verified traditional indigenous knowledge. For a long time, the Polaris people have recognized the unique features of polar bears and incorporated them into tools and clothing designed by hunting. It is worth noting that their traditional preparation methods retain the natural oil of fur, which indicates that it has an intuitive understanding of its acid resistance characteristics.
This research cooperation involves institutions from Norway, Ireland, Britain, and Denmark. It uses advanced analysis technologies, including mass spectrometry and nuclear magnetic resonance to reveal the molecules of bear coatings. These findings can change multiple industries from aviation to renewable energy infrastructure to prevent ice.
