MODIFICATION OF POLYOLEFINS WITH METAL OXIDE OLIGOMERIC MODIFIERS

Modification of Polyaniline/Polystyrene and Polyaniline/Metal Oxide Structure by Surfactant

Polyaniline/polystyrene (PAni/PS) composites were prepared in aqueous solution by polymerization of styrene and aniline in two-stages. Firstly styrene polymerize by using Ammonium persulfate (APS) as an oxidant in the presence of various surfactants such as poly(vinyl pyrrolidone) (PVP), hydroxypropylcellulose (HPC), poly(vinyl alcohol) (PVA) and surfactive dopant sodium dodecylbenzenesulfonate...

Self-assembled hybrid metal oxide base catalysts prepared by simply mixing with organic modifiers

Multidentate materials formed by simply mixing heterogeneous and homogeneous components are promising for construction of versatile active sites on the surface of heterogeneous compounds, however, to the best of our knowledge, there are no reports on such materials. Self-assembly of hetero-hybrid catalytic materials occurs when heterogeneous catalysts having adjacent Lewis acid-Lewis base sites...

Triazavirine supramolecular complexes as modifiers of the peptide oligomeric structure.

In this study, we present molecular dynamics simulations of the antiviral drug triazavirine, that affects formation of amyloid-like fibrils of the model peptide (SI). According to our simulations, triazavirine is able to form linear supramolecular structures which can act as shields and prevent interactions between SI monomers. This model, as validated by simulations, provides an adequate expla...

Surface modification of TiO2 with metal oxide nanoclusters: a route to composite photocatalytic materials.

Density functional theory simulations show that modifying rutile TiO(2) with metal oxide nanoclusters produces composite materials with potential visible light photocatalytic activity.
