CNN News: 無(wú)限的可能性

Imagine a world where your smartphone touchscreen never breaks, instead it bends, and the antenna inside, so fast it can transfer a terabit of data in a second, and the battery so powerful, it can fly an airplane.

想象這樣一個(gè)世界，智能手機(jī)的觸摸屏從來(lái)不會(huì)破碎，相反它可以彎曲，同時(shí)，內(nèi)置天線，傳輸速度之快，秒鐘之間就可以傳輸一比特信息，電力強(qiáng)勁，可以用于駕駛飛機(jī)。

What if I told you there was one substance that can make all of this possible?

如果我告訴你，有一種物質(zhì)能讓所有的一切變成現(xiàn)實(shí)?

This is graphene, the miracle material of the future. Scientists say it`s the thinnest, lightest and strongest stable material known on earth.

這種物質(zhì)就是石墨烯，這種未來(lái)神奇的物質(zhì)?？茖W(xué)家稱該物質(zhì)是目前為止人類知道的地球上最薄、最輕、最堅(jiān)韌穩(wěn)定的物質(zhì)。

It`s so strong it`s up to 200 times stronger than steel and harder than diamond. It`s so light that if you had a sheet of graphene the size of a football field, you could hold it between your thumb and finger and it wouldn`t bend or break. And it`s so thin it`s just one atom thick.

該種物質(zhì)非常的強(qiáng)韌，其堅(jiān)韌度比鋼鐵強(qiáng)200倍，硬度比金剛石硬200倍。石墨烯的延展性非常的好，一塊石墨烯可以延展出足球場(chǎng)的大小，同時(shí)你可以將其夾在拇指間，而不會(huì)彎曲和破碎。同時(shí)石墨烯的薄度僅有一個(gè)原子的厚度。

That`s right. Graphene is the world`s first two-dimensional material. How was it even possible? For decades, scientists weren`t even sure that it was until 2004 when physicists examined a piece of scotch tape used to peel off thin layers of carbon from a slab of graphite. What they discovered was graphene, a single layer of carbon atoms arranged in a honeycomb pattern which gave the material extraordinary properties.

對(duì)的，石墨烯是世界上首個(gè)二位材料。怎么會(huì)這樣呢?幾十年以來(lái)，科學(xué)家們并不確定直到2004年，物理學(xué)家研究了一塊透明膠帶用于剝離薄層的碳石墨板?？茖W(xué)家們發(fā)現(xiàn)的就是石墨烯，一種單層碳原子以蜂窩的模式排列，該種結(jié)構(gòu)讓石墨烯具有了特殊的性質(zhì)。

It`s transparent but it can absorb light. It`s elastic, and pliable but also impermeable to all gases and liquids except for water. And it`s the world`s best conductor of heat and electricity.

石墨烯是透明的，但是卻能吸收光線。其柔軟具有彈性，但卻不能滲透除了水以外其他液體和氣體。石墨烯是世界上最好的熱電導(dǎo)體。

This could lead to faster computer chips, longer lasting batteries, wearable solar panels. Imagine, battery powered electric airplanes, cancer detecting nano-sensors, unlimited supplies of cheap desalinated ocean water. The possibilities are limitless.

該種物質(zhì)能讓電腦芯片運(yùn)轉(zhuǎn)速度更快，電池蓄電時(shí)間更長(zhǎng)，太陽(yáng)能極板更耐用。想象一下，用電池為電動(dòng)飛機(jī)、癌癥檢測(cè)納米傳感器、海水淡化設(shè)備提供電能?？赡苄允菬o(wú)限的。

So, what`s stopping us? A flake of graphene just a micrometer thick can cost over $1,000 to make using the scotch tape method, making it possibly the most expensive manmade material on earth.

但是什么在阻止我們呢?片狀的石墨烯僅僅有一微米厚，卻要耗資1000度美元通過(guò)制作透明膠帶的方法獲得。是世界上價(jià)錢最昂貴的人工制作材料。

Another problem? Regular graphene lacks what`s called a "band gap", the property that allows it to function as a switch. You want your devices to turn on and off. It will likely take a large company with deep pockets to solve these problems.

另外一個(gè)問(wèn)題?常規(guī)的石墨烯缺乏所謂的“帶隙”，該性質(zhì)可以讓其功能類似于開(kāi)關(guān)。你想要自己的設(shè)備開(kāi)關(guān)。這可能需要資金雄厚的公司才能解決這些問(wèn)題。

Until then, graphene`s applications are limited to things like tennis racquets, skis and light bulbs, not exactly game-changing. But it`s only been about a decade since graphene was discovered. Since then, labs and companies have put billions into research in a race to unlock graphene`s limitless potential.

直到現(xiàn)在，在不完全改變石墨烯的性質(zhì)下，其應(yīng)用僅限于網(wǎng)球拍，滑雪板和燈泡，但是這距離發(fā)現(xiàn)石墨烯僅有十年。之后，實(shí)驗(yàn)室和公司們已經(jīng)投入數(shù)十億競(jìng)相研究石墨烯無(wú)限潛力。

Only time will tell if the miracle material of the future ever arrives.

只有時(shí)間能告訴我們這個(gè)神奇材料的未來(lái)是否會(huì)來(lái)臨。
