Niobium is fairly inert, high melting point and has a low neutron cross section.

A long while ago, I got a patent on the use of a niobium compound that was a catalyst, along with a sister tantalum compound. These were superacids, such as [H2F][NbF6].

Tantalum and niobium are also relatively non-toxic -can be used like titanium inside the human body - and it turns out that your cellphone needs a capacitor made of tantalum and tantalum oxide to work, and that is why tantalum is in such hot demand, and also exploited by some very evil scumbags in central Africa. But, good news, because a company called Vishay in Niagara Falls has just come up with a way to use niobium and it's oxide for the same use. And niobium is much more common than tantalum.

And so, I adopted it for a e-name. And every once in a while, you find people who are "elementarily" aware...
