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.
据英国《每日邮报》11月11日报道，一位美国德克萨斯大学的物理学家成功研制出了《哈利波特》故事里面的“隐形斗篷”。
这项壮举背后的研究员阿里-阿利耶夫称他能利用碳纳米管制出这种斗篷。这种隐形斗篷看上去就像薄线衣。
阿利耶夫先生告诉微软全国广播公司的记者：“我们真的可以隐藏物体……我们能用很短的时间切换空间并使之消失。”
发布在You Tube上的一个视频展示了阿利耶夫在实验室里让这些细线出现以及消失的景象。
他告诉网友们说：“这个实验对普通人来说是很有趣的，因为科学家们通常只在显微镜下展示一些极其微小的东西。但是这在里，真实的物体立即就消失了。”
在瑞典，科学家们正致力于研制一种可以保护坦克避开热导飞弹的隐形斗篷。
这项新技术已经用于扫描读取附近的建筑物和地形，以及重现车辆外壳的冷热面板格局。
