In this work, we successfully synthesized novel polymer gel beads based on functionalized iron oxide (Fe3O4), activated charcoal (AC) particles with β-cyclodextrin (CD) and sodium alginate (SA) polymer (Fe3O4/CD/AC/SA), by a simple, reproducible and inexpensive method. These beads proved to be versa...

New magnetic iron oxide (Fe3O4)/activated charcoal (AC)/β-cyclodextrin (CD)/sodium alginate (Alg) polymer nanocomposite materials were prepared by direct mixing of the polymer matrix with the nanofillers. The obtained materials were utilized as nano-adsorbents for the elimination of methylene blue (...

Flat crystal ZnO thin films were prepared by chemical bath deposition technique onto glass substrates. XRD patterns of the films deposited at about 80 °C and annealed at 200 °C for 1 h in oxygen environment revealed the existence of polycrystalline hexagonal wurtzite phase with c-axis orientation of...

Polyaniline-manganese dioxide (PAni-MnO2) composites of varying compositions were prepared by in situ chemical oxidative polymerization of aniline monomer in aqueous acidic medium in the presence of different amounts of MnO2 formed in situ by the reaction of MnSO4 with KMnO4. PAni was also synthesiz...

Ceria nanoparticles (NPs) are promising materials for their superior anticancer and antifungal activities. In this work, we synthesized Fe-doped ceria NPs by co-precipitation method using xanthan gum (XG) as a green capping agent. The NPs were calcined at different temperatures ranging from 200 to 8...

Hypothesis Water in oil microemulsion (w/o) is a simple preparative route for nanoparticles where water droplets (dispersed in continuous oil medium and stabilized by surfactants and cosurfactants) act as nanoreactors to carry out chemical reactions. If polymeric matrix is incorporated inside the co...
