世界上最小元素周期表 印在头发上

　　According to newscientist.com on December 27, professor Martyn Poliakoff at Nottingham University, UK, printed a periodic table on his single hair, making out world's smallest periodic table. To achieve this nanoscale feat, Poliakoff and his colleagues magnified the hair in an electron microscope, then used an ion beam writer to bombard the hair.

　　来自英国诺丁汉大学的马丁 伯利克夫在自己的一根头发上“印”上了化学元素符号，使其成为世界上最小的元素周期表。据了解，伯利克夫和同事们用电子显微镜将发丝放大，随后用离子光束笔对发丝进行“轰炸”，才得以完成这个纳米级别的作品。
