When I say something new I do not refer to something already made like H,O etc and when I mean something new I do not refer to a transformation like tritium to helium and gold. If so how ?(I mean is there a specific way to do that ?)
Yes, so far, 20 synthetic elements have been created, with atomic numbers 99 (Einsteinium) to 118 (Ununoctium). All these elements are unstable, with half-lives ranging from a year to a few milliseconds.
You can find a list on wikipedia. These elements are produced in specialized nuclear reactors, by bombarding heavy elements like Uranium and Plutonium with neutrons or other elements.

some teams of physicists around the world are working on achieving that. And from time to time they do. The smash large nucleus onto each other and sometimes they fuse and result in an atomic nucleus belonging to a new element. Unfortunately, these nuclei are very short lived so you cannot create a stable bulk material with them. However, it is predicted that there is some "island of stability" in which a particular set of these new elements will become more or less stable. How stable, is anybody's guess. But scientists are close to having the tech to create these kind of elements, probably in the next few years.
