The team sought to replicate the key aspects of hot springs prior to life, and see if iron sulfides could stand in for catalyzing enzymes. They experimented with pure FeS, but also tried iron ...

Iron sulfide, a new substance ... A few of these elements can be found pure in a natural state. For example, graphite and diamond can be found in rocks in the Earth’s crust, and they are ...

Pure sulfide chalcopyrite, Cu(In,Ga)S 2, is a promising semiconductor material with a bandgap between 1.5 and 2.4 eV, which has already been used to build single-junction and tandem solar cells.
