불개미에 영감 받은 가라앉지 않는 선박을 만들 수 있는 새로운 금속 VIDEO: New metal inspired by fire ants could lead to UNSINKABLE ships and flotation aids that still work after being punctured
New metal inspired by fire ants could lead to UNSINKABLE ships and flotation aids that still work after being punctured
The surfaces become superhydrophobic (extremely water resistant) and can keep water from entering the central compartment even when the structure is forced to submerge under water
Fire ants create floating rafts by trapping air within their water resistant limbs
The new metal is created by etching tiny lines that are able to trap air in bubbles
Even if it is forced underwater the metal can still float after the pressure is lifted
불개미에 영감 받은 가라앉지 않는 선박을 만들 수 있는 새로운 금속 로체스터 대학 연구원 불개미에 의해 영감을 받은 새로운 금속은 가라앉지 않는 선박과 구멍 난 후에도 여전히 작동되는 부양 보조 장치로 이어질 수 있을 것이다.. 불개미들과 다이빙벨거미는 물속에 잘 견디는 새로운 금속을 만들어내는데 영감을 주어 언젠가는 가라앉지 않는 배들이 생겨날 수도 있다. 이 금속은 매우 짧은 레이저 버스트를 사용하여 공기를 가두어 놓는 표면에 작은 무늬를 '가져오'면서 생성된다. 로체스터 대학의 연구원들에 따르면, 이 금속이 강제로 가라앉을지라도, 그것은 표면으로 돌아와 압력이 제거되는 즉시 계속 떠 있을 것이라고 한다. 이 연구를 이끈 천레이 구오 교수는 '이것은 가라앉지 않는 배, 구멍을 뚫은 후에도 여전히 떠다니는 마모성 부양 장치, 그리고 심지어 바다에서 장기간 생존할 수 있는 전자 감시 장치까지 만들어낼 수 있다'고 말했다. 불개미는 몸으로 뗏목을 만들면서 물 속이나 수면 위에서 오랜 시간 생존할 수 있다. 그런 다음 매우 물에 잘 견디는 몸 사이에 공기를 가두어 놓아 그들을 떠 있게 한다. 황기철 콘페이퍼 에디터 큐레이터 Ki Chul Hwang, conpaper editor, curator edited by kcontents |

Fire ants and a diving bell spider have inspired the creation of a new metal that is so water resistant that it could one day lead to the creation of unsinkable ships.
The metal is created using very short bursts of lasers to 'etch' tiny patterns on its surface that trap air.
Even if the metal is forced to sink, it will return to the surface and continue to float as soon as the pressure is removed, according to researchers from the University of Rochester.
The team took inspiration from fire ants that lock their limbs together on water to trap pockets of air between their extremely water resistant limbs which keep them afloat as a group
'This could lead to an unsinkable ship, a wearable flotation device that will still float after being punctured and even electronic monitoring devices that can survive in long term in the ocean,' said Professor Chunlei Guo, who led the study
Fire ants are able to survive long periods of time under or on the surface of water by joining their limbs together to form a raft.
They then trap air among their very water-resistant bodies, which keeps them afloat.
The process involves placing two treated metal surfaces facing inwards with just enough space between them to create a bubble of air
The team at the University of Rochester tried piercing the surface and found it was still able to float as part of the bubble of air would remain intact
