这张元素表中包含了118个化学元素符号

Scientists have written what they believe is the world's smallest periodic table - on a strand of human hair.
科学家在人的一根头发上刻出了他们相信是世界上最小的元素周期表。

Experts at Nottingham University created the table which is so small that one million of them could be replicated on a standard Post-It note, using a combination of an ion beam writer and electron microscope.
诺丁汉大学的研究人员制出的这个元素周期表非常小。在常用的约手掌大小的便签上，可以容纳数百万个这样大小的元素周期表。

马丁·波利亚科夫教授

The symbols of all 118 elements were etched into the strand of hair taken from Professor Martyn Poliakoff, an expert in green chemistry. It was then presented to him as a birthday present.
这根承载着118个化学元素符号的头发取自绿色化学领域的专家马丁·波利亚科夫教授。之后作为生日礼物送给了他。

教授认为更重要是展示纳米刻录技术

Prof Poliakoff said: 'Although the application was lighthearted I felt that it enabled us to show people how such nano-writing is done.'
波利亚科夫教授说：“虽然在头发上刻元素周期表的方式比较有趣，但是我觉得它更向人们展示了纳米刻录技术是如何应用的。”
