Hydrogen sulfide (H2S) is a colourless, highly toxic, corrosive and flammable gas which adversely affects human health as it can cause neurological and respiratory diseases at low concentrations (ppm), even deaths if H2S concentration exceeds 250 ppm [[1], [2], [3], [4]]. Therefore, the...
Recently, it is shown that by intercalating the so-called neutral layers, like molecules Lix(NH2)y(NH3)1–y, between the FeSe layers one can produce the 122 structure with much higher Fe concentration without inducing large electrostatic force and thus lead to the superconducting samples with ...
