The team at the Max-Planck Institute for Chemistry (Mainz, Germany), the University of Chicago (USA), and the Soreq Nuclear Research Center (Yavne, Israel) used a variety of analytical methods to refine the phase diagrams for hydrogen sulfide in the H(3)S form and D(3)S, its deuterium analogue, in relation to pressure and temperature, and to shed […]

Hydrogen sulfide, the gas with a telltale rotten-egg smell often called and found in sewer gas could greatly enhance plant growth in low doses.  Hydrogen sulfide remains in higher concentrations a deadly substance implicated in several mass extinctions.  At high concentrations – levels of only 30 to 100 parts per million in water – hydrogen […]
