Wine can help keep conversation _____1_____ at a dinner party. And now it looks like that wine may aid in materials science as well. Japanese researchers discovered that hot alcoholic beverages induce superconductivity in iron-based compounds.
These compounds can become superconducting by _____2_____ oxygen, but it takes months. Scientists have been searching for a way to speed that up.
So researchers at Japan’s National Institute for Materials Science decided to test the reaction with alcohol.
They put samples of the compounds in red and white wines, beer, sake, shochu— another Japanese alcohol—and whiskey. There were ____3____ water-ethanol mixtures.
The samples were heated to 70 degrees Celcius for 24 hours.
The water ethanol mixtures didn’t have _____4_____, but the drinks did induce superconductivity—red wine best of all.
The scientists speculate there may be particular elements in red wine that are replacing elements in the iron-based compounds.
It may be that wine speeds up the supply of oxygen into the samples.
The researchers say the next step is to analyze the beverages to figure out just what’s inducing superconductivity.
And maybe _____5_____ in the process.

酒精飲料誘發(fā)超導(dǎo)性 在晚宴上，酒能使人侃侃而談。而現(xiàn)在來(lái)看，酒也可能在材料科學(xué)方面派上用場(chǎng)。日本研究者發(fā)現(xiàn)熱酒精飲料能誘發(fā)鐵基化合物中的超導(dǎo)性能。這些化合物通過(guò)接觸氧氣而帶有超導(dǎo)性，不過(guò)這需要幾個(gè)月才能實(shí)現(xiàn)?？茖W(xué)家一直在研究一種可以加速這個(gè)過(guò)程的方法。所以日本國(guó)立材料科學(xué)研究所的研究員決定測(cè)試酒精的反應(yīng)。 他們?cè)诩t酒、白酒、啤酒、米酒、燒酒（日本的另一種酒）和威士忌中分別加入化合物樣本。并且調(diào)配了水和乙醇的混合液作為對(duì)照，加入樣本中。加熱樣本24小時(shí)，溫度達(dá)到70攝氏度。水和乙醇混合液并沒有產(chǎn)生多大的效果，但這些酒精飲料卻的確能誘發(fā)超導(dǎo)性，紅酒的效果最好?？茖W(xué)家推測(cè)紅酒中可能含有特殊成分，能代替鐵基化合物中的元素。 酒精可能使氧氣更快地進(jìn)入樣本中。研究者稱，下一步要對(duì)飲料進(jìn)行分析，找出是什么物質(zhì)誘發(fā)了超導(dǎo)性。而且在研究的時(shí)候喝上一小口也說(shuō)不定。
