1) Elemental Rebalancing - Forget that nonsense you learned in chemistry, every object is made up of the four elements, and the balance between them is what gives things their unique properties. With your mastery of the elements, you are now able to tamper with that balance. Hope you know what you're doing.
2) Molecular Meddling - You can only take things apart and reassemble them in so many different ways in the macro scale. But with an electron microscope here and a nanobot there... well, you can make shiny new toys out of the stuff you've already got.
3) Canadium - cold
Cranium - phychic
Electrum - electric
Thompsium - acid (after Hunter S. Thompson)
Venerabum - sonic (If it's too loud, you're too old)
Terracottite - brittle (to be combined with other things as in modern body armor

Ireite - +melee (play on Pyrite)
