Water-Tree Resistant Characteristics of Crosslinker-Modified-SiO2/XLPE Nanocomposites

EPDM/modified halloysite nanocomposites

Processing and analysis of chitosan nanocomposites reinforced with chitin whiskers and tannic acid as a crosslinker.

Chitosan film reinforced with nano-sized chitin whiskers and crosslinked using tannic acid was synthesized by the casting-vaporation method. The mechanical and physicochemical properties of several film samples (consisting of different ratio of chitin and tannic acid) were compared with neat chitosan. Tensile tests show that the addition of chitin improves the nanocomposite films mechanical pro...

Enzymatic activation of oleuropein: a protein crosslinker used as a chemical defense in the privet tree.

Leaves of the privet tree, Ligustrum obtusifolium, contain a large amount of oleuropein, a phenolic secoiridoid glycoside, which is stably kept in a compartment separate from activating enzymes. When the leaf tissue is destroyed by herbivores, enzymes localized in organelles start to activate oleuropein into a very strong protein denaturant that has protein-crosslinking and lysine-decreasing ac...

Thermal Stability and Crystallization Behaviour of Modified ABS/PP Nanocomposites

In this research work, poly (acrylonitrile-butadienestyrene)/polypropylene (ABS/PP) blends were processed by melt compounding in a twin-screw extruder. Upgrading of the thermal characteristics of the obtained materials was attempted by the incorporation of organically modified montmorillonite (OMMT), as well as, by the addition of two types of compatibilizers; polypropylene grafted with maleic ...

Continuous-Flow Photocatalytic Degradation of Organics Using Modified TiO2 Nanocomposites

In this study, TiO2 nanotubes (TNTs) were fabricated on a Ti sheet following the anodic oxidation method and were decorated with reduced graphene oxide (RGO), graphene oxide (GO), and bismuth (Bi) via electrodeposition. The surface morphologies, crystal structures, and compositions of the catalyst were characterized by field emission scanning electron microscopy, Auger electron spectroscopy, X-...
