I heard about this, it's pretty cool! Apparently they're now continuing to look for more.
They will FOREVER look for more.
In particular, what physicists REALLY hope to achieve is what is known as the "island of stability". Like a lot of physics things that we're trying to find through experimentation, this is all theoretical. At the moment, the heaver the atom we make, the less stable it is, some of them only lasting for mere femtoseconds (10^(-15) seconds). However, physicists believe that after a certain point, the so called "island of stability", this trend will reverse, and the atoms will become MORE stable, allowing us what could be a never-ending supply of resources. (mainly in terms of stuff that is reallllllly not renewable and we're running out of)
Man that's cool and beneficial at the same time. Are these the kinds of pracs or research you do at uni?
This was research - if you want to know more about what I was looking out, check out
this post here. I didn't do research into acids/bases, mind, I just used them for my research.
In particular, hydrochloric acid acted as a solvent for one of my reactions - in the last step of the reaction, addition of acid caused what I was aiming to make to precipitate out, then I just had to vacuum it for the desired product. I don't think I used any more acid, but lots of others in the lab were using them as catalysts for their reactions. The only base that regularly got used was the base baths, though, and they were only used for cleaning glassware.
