When a nitrogen atom sits next to a vacant spot in the carbon crystal, the intruding element provides an extra electron that moves into the hole.
当氮原子与碳晶体中的空心点相邻时，氮元素会产生特定的电子，这些电子可以移动到那个空心点里。
African Anopheles mosquitoes find us by our carbon-dioxide-rich exhalation. But when they get close they turn away from our heads and dive for our feet-apparently their preferred snack spot.
非洲疟蚊通过我们富含二氧化碳的呼出物找到我们，它们不叮咬我们的头部，转而去叮咬我们的脚，显然那儿才是它们觅食的最佳场所。
Now with this particular piece of instrumentation, you can actually spot individual carbon atoms.
