Neodymium is next to Promethium, then 62's.

钕的下一个是钷，是62号。

Could demand for dysprosium and neodymium then be met?

到那时，镝与钕的需求也会得到满足吗？

Often, the metal responsible is iron, but rare earth elements like neodymium can do it too.

通常，造成这种情况的金属元素是铁，但是地球上的稀有元素如钕同样有此效果。

Recycling is worth it when it comes to all metals, though we're better at recycling aluminum than say neodymium.

所有的金属回收都是值得的，尽管相比钕在回收铝方面我们更为拿手。

Researchers are hoping to replace neodymium in future versions of these robots.

研究人员希望在这些机器人的未来版本中取代钕。

To create a millimeter-scale robot capable of feats of flexibility, the researchers embedded magnetic particles of the element neodymium in pliable material.

为制造出具有灵活性的毫米级机器人，研究人员将钕元素的磁性颗粒嵌入柔韧材料中。

The researchers then used a pair of powerful magnets to flip the polarity of the neodymium particles in different sections of the robot and UV light to lock them into place.

然后，研究人员使用一对强大的磁铁来翻转机器人不同部分中钕粒子的极性，并用紫外线将它们锁定到位。

Like lead or mercury, neodymium is a toxic heavy metal that would need to be removed from inside the body if the bots were being used to assist a surgery or deliver drugs.

与铅或汞一样，钕是一种有毒的重金属，如果机器人用于辅助手术或输送药物，则需要将其从体内清除。
