Antibacterial properties of nanoporous graphene oxide/cobalt metal organic framework.

Numai utilizatorii înregistrați pot traduce articole

Metal-organic framework (MOF) based graphene oxide (GO) recently merits of attention because of the relative correspondence of GO with metal ions and organic binding linkers. Furthermore, introducing the GO to the Co-MOF to make a new nanoporous hybrid have are improved the selectivity and stability

Screening seeds of Scottish plants for antibacterial activity.

Numai utilizatorii înregistrați pot traduce articole

Based on ethnopharmacological and taxonomic information, seeds of 21 Scottish plant species from 14 different families were obtained from authentic seed suppliers. Their n-hexane, dichloromethane and methanol extracts were assessed for antibacterial activity against 11 pathogenic bacterial species.
