(
Elsevier Ltd
, 2021 , Article Review)
Proton Exchange Membrane Fuel Cells (PEMFCs) have the perspective to intensely decrease global emission through environmentally-friendly potential. This review paper summarizes the degradation of platinum catalyst layer ...
A theoretical study of gas adsorption on α-quartz (0 0 1) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2020 , Article)
The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on the “dense” (0 0 1) surface of α-quartz has been investigated by means of Density Functional Theory (DFT) for the molecular characterization of Enhanced Gas ...
