Graphene Oxide/Polyvinyl Alcohol/FeO Nanocomposite: An Efficient Adsorbent for Co(II) Ion Removal.

In this work, an effective nanocomposite-based adsorbent directed to adsorb cobalt (Co) ion was successfully synthesized from graphene oxide (GO), polyvinyl alcohol (PVA), and magnetite (FeO) nanoparticles via a coprecipitation technique. The synthesized GO/PVA/FeO nanocomposite was applied for Co ion removal with the optimized working conditions including 100 min of contact time, 0.01 g of adsorbent dosage, pH of 5.

Molecular surveillance and temporal monitoring of malaria parasites in focal Vietnamese provinces.

Background: While the World Health Organization (WHO) Southeast Asia region has the second highest incidence of malaria worldwide, malaria in Vietnam is focal to few provinces, where delayed parasite clearance to anti-malarial drugs is documented. This study aims to understand Plasmodium species distribution and the genetic diversity of msp1 and msp2 of parasite populations using molecular tools.

Methods: A total of 222 clinical isolates from individuals with uncomplicated malaria were subjected to Plasmodium species identification by nested real-time PCR.
