Abstract: Present disclosure discloses a system for separating hydrogen from feed gas. The system includes at least one compressor adapted to pressurize the feed gas to predefined pressure. One or more adsorber columns are fluidly coupled to the compressor and are adapted to receive the pressurized feed gas, where the adsorber columns include a body and an adsorber bed, which is disposed within the body. The adsorber bed is configured to separate hydrogen from the feed gas. Further, the one or more adsorber columns includes a plurality of channels defined in at least one of the adsorber bed and adjacently along a length of the adsorber bed, where the channels are configured to channelize the hydrogen and regulate temperature of the adsorber bed. The configuration of the system aids in extracting pure hydrogen at low feed gas pressure.

Abstract: The present disclosure is directed to double perovskite oxide semiconductors. In particular, the present disclosure is directed to lead-free double perovskite oxides that provide excellent stability and are used, for example, as photovoltaic materials.
