美科學家研製出《哈利波特》“隱形斗篷”
A physicist at the University of Texas Dallas has successfully created the elusive invisibility cloak immortalized in the pages of Harry Potter.
Ali Aliev, the researcher behind the feat, said he was able to make the cloak using carbon nanotubes, which look like thin strands of thread.
Mr Aliev told MSNBC: "We really can hide objects. ... We can switch for a short moment and make it disappear.”
In a video posted to YouTube, the strands are seen appearing and disappearing during a demonstration in Mr Aliev’s lab.
He told the network: “It's interesting for ordinary people, because usually [scientists] show something micro sized under some microscope. But here, in real time, real objects [were] disappearing.”
In Sweden, scientists are working on an invisibility cloak which could protect tanks from heat seeking missiles.
The new technology has scanners to read nearby buildings and terrain and can reproduce their pattern of hot and cold on panels on the hull of the vehicle.據英國《每日郵報》11月11日報道，一位美國德克薩斯大學的物理學家成功研製出了《哈利波特》(微博)故事裏面的“隱形斗篷”。
這項壯舉背後的研究員阿里-阿利耶夫稱他能利用碳納米管制出這種斗篷。這種隱形斗篷看上去就像薄線衣。
阿利耶夫先生告訴微軟全國廣播公司的記者：“我們真的可以隱藏物體……我們能用很短的時間切換空間並使之消失。”
發佈在You Tube上的一個視頻展示了阿利耶夫在實驗室裏讓這些細線出現以及消失的景象。
他告訴網友們說：“這個實驗對普通人來說是很有趣的，因爲科學家們通常只在顯微鏡下展示一些極其微小的東西。但是這在裏，真實的物體立即就消失了。”
在瑞典，科學家們正致力於研製一種可以保護坦克避開熱導飛彈的隱形斗篷。
這項新技術已經用於掃描讀取附近的建築物和地形，以及重現車輛外殼的冷熱面板格局。
