DFT investigation of H2S adsorption on graphenenanosheets and nanoribbons: Comparative study
(
Elsevier
, 2020 , Article)
Graphenenanosheet (GNS), armchair graphenenanoribbon (AGNR), and zigzag graphenenanoribbon (ZGNR) systems were investigated by first principle calculations using the density functional theory (DFT). The DFT calculations ...
Antibiotic resistance profile of commensal Escherichia coli isolated from healthy sheep in Qatar
(2020 , Article)
Introduction: The uncontrolled antibiotics use in livestock is a leading factor for the emergence and spread of resistant bacteria from food animals to humans through the food chain. This study aims at evaluating the ...
