Immobilization of AgZnO photocatalyst in Poly(acrylic acid) matrix and their photocatalytic activity evaluation

Jasso-Salcedo A.B., Meimaroglou D., Camargo M., Hoppe S., Pla F., Escobar-Barrios V.A., IPICYT, MX

The Ag modified Zinc oxide (AgZnO) is a catalyst with increased photocatalytic activity used for degradation of dyes and several organic molecules, in aqueous solution, in contrast to pure ZnO. Nevertheless, its application at pilot [...]

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 [...]

Effect of Dispersion Conditions on the Thermo-Mechanical Properties of Functionalized Carbon Nanotube-Reinforced Vinyl Ester

Sabet S.M., Mahfuz H., Hashemi J., Florida Atlantic University, US

To date, controlling the microstructure of carbon nanotube (CNT)-polymer composites remains a challenge due to high tendency of CNTs to aggregate. Proper dispersion of CNTs in the matrix has to be guaranteed to employ CNTs [...]

Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)

Milionis A., Yeong Y.H., Loth E., Bayer I.S., University of Virginia, US

We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]

Graphene/polyaniline nanocomposite modified electrode for biosensors

Chailapakul O., Yukirdb J., Rodthongkum N., Rangkupan R., Pisitkun T., Chulalongkorn University, TH

A novel system based on graphene/polyaniline nanocomposite modified electrode was successfully developed for sensitive and specific determination of NGAL protein biomarker. Then, the optimum conditions were applied for the detection of NGAL in real biological [...]

SWCNT/Inorganic polymer nanocomposite: a new class of Transparent Conductor and UV-Vis Photo – Generator

Bose S., Balaji S., Debnath R., Jadavpur University, IN

Synthesis of a light sensitive SWCNT/(Pb, Zn)-phosphate glass composite and it’s optical, light induced ESR, electronic and optoelectronic properties are reported. Absorption spectrum of SWCNTs of the composite differs from that of its film. Since [...]

Synthesis and Characterization of Nanocomposites Using the Nanoscale Laser Soldering in Liquid Technique

Phuoc T.X., Mcintyre D., Song X., Chyu M.K., National Energy Technology Lab, US

It has been known that catalytic and sensing properties of semiconductor and metal nanoparticles (NPs) can be greatly enhanced if they are made in the form of nanocomposites. For that reason, in this work, we [...]

The Coupled Electro-Mechanical Behaviour of Nanocomposites

Wernik J.M., Meguid S.A., University of Toronto, CA

In the past two decades, practical realisation of composites began to shift from microscale-reinforced composites to nano-reinforced composites using carbon nanotubes (CNTs). There are a number of advantages that result from dispersing CNTs into polymeric [...]

SWCNT/Inorganic polymer nanocomposite: a new class of Transparent Conductor and UV-Vis Photo – Generator

Bose S., Balaji S., Debnath R., Jadavpur University, IN

Synthesis of a light sensitive SWCNT/(Pb, Zn)-phosphate glass composite and it’s optical, light induced ESR, electronic and optoelectronic properties are reported. Absorption spectrum of SWCNTs of the composite differs from that of its film. Since [...]

Nanomaterials as Nanocomposite Fillers: Cytotoxicity at Different Stages of Their Life Cycle

Mas del Molino E., Vilar G., Janer G., Fernández-Rosas E., Vázquez-Campos S., LEITAT Technological Center, ES

Since the production and utilities of NM have been growing exponentially we have decided to perform cell viability tests and mechanistic assays using different cell lines to assess the potential cytotoxicity of raw MWCNT, hydrophilic [...]
