Nuclear fusion-fission hybrid — Hybrid nuclear fusion fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s … Wikipedia
Synthesis of noble metals — refers to the realization of the age old dream of alchemists to artificially produce noble metals. The goal of this could be to achieve greater economic gain when compared to traditional methods of obtaining noble metals. Synthesis of noble… … Wikipedia
