Photocatalytic Silver/Silver Halide Polymer Nanocomposites

Tate E., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Recently it has been shown that hybrid silver/silver halide nanoparticles exhibit interesting photocatalytic properties, and are known plasmonic photocatalysts. Enhanced photostability and photocatalysis are observed in the nanoparticles due to the surface plasmon resonance of [...]

Water-dispersible graphene stabilized by PVA grafted graphene and its poly (vinyl alcohol) nanocomposites

Shang S.M., Gan L., Yuen M.C.W., The Hong Kong Polytechnic University, HK

In this study, we synthesized poly (vinyl alcohol) (PVA) functionalized graphene oxide (f-G) by esterification reaction and used this f-G to stabilize the dispersion of graphene in water. Finally, we used the f-G stabilized graphene [...]

Interlaminar resistive heating behavior of woven carbon fiber composite laminates modified with ZnO nanorods

Kong K., Deka B.K., Park H-W., Ulsan National Institute of Science and Technology (, KR

In this study, the electrical resistive heating of the ZnO/woven carbon fiber composite on the interlaminar region was evaluated. In ZnO/woven carbon fiber composite laminates, the interlaminar region, composed of ZnO nanostructured arrays embedded on [...]

Laser-induced synthesis of hybrid C-Au-Ag nanostructures: nanoparticles, nanoflakes, nanoflowers

Manshina A., Povolotskiy A., Povolotskaya A., Koshevoy I., Tunik S., St. Petersburg State University, RU

Metallic silver-gold nanoparticles (1–5 nm) encapsulated into carbon nanospheres (20–30 nm), or carbon flakes and flowers were synthesized via laser-induced chemical liquid phase deposition. The obtained carbon-silver-gold nanostructures are characterized by high specific surface area [...]

Composite of silver nanoparticles in glass nanofibers produced by Laser Spinning

Cabal B., Quintero F., Díaz L.A., Rojo F., Dieste O., Pou J., Torrecillas R., Moya J.S., University of Vigo, ES

In this work we present a new approach to produce a nanocomposite made of non-woven silicate glass fibers containing silver nanoparticles. The process first involves the synthesis of pellets of a soda-lime silicate glass containing [...]

Novel Aluminum-CNT composites for structural applications

Esawi A.M.K., Salama E., The American University in Cairo, EG

The latest enhancements in the mechanical behaviour of Al-CNT composites achieved by the research group are presented : an increase in tensile strength, indentation hardness and Young’s modulus of 69%, 72% and 23%, respectively. The [...]

Flame retardant Polypropylene nanocomposites: Catalytic and synergistic effects between maleic anhydride grafted Polypropylene and cobalt nanoparticles

He Q., Lamar University, US

A novel function of polypropylene grafted with maleic anhydride (PP-g-MA) as synergistic additive to eﬀectively reduce the flammability of polypropylene (PP) nanocomposites (PNCs)reinforced with in situ synthesized cobalt (Co)–cobalt oxide core–shell nanoparticles (NPs) was reported.

Using Magnetic Impact Coating Technique to Prepare Carbon Nanotube-Reinforced Polymer Nanocomposites

Narh K.A., New Jersey Institute of Technology, US

The combination of high aspect ratio, small size, very low density, and more importantly, excellent physical properties, such as extremely high mechanical strength and stiffness, high electrical and thermal conductivity, make carbon nanotubes (CNTs) perfect [...]

Scale-up of Novel Gold Nanoparticle-Wool Fiber Composites: A Commercialisation Success Story
