Structural and rheological investigation of Fd3m inverse micellar cubic phases

Pouzot M., Mezzenga R., Leser M., Sagalowicz L., Nestlé Research Center, CH

Liquid crystalline phases (bicontinuous cubic, reversed hexagonal, lamellar) can be made easily from food emulsifiers such as monoglycerides. Recently we explored in detail the formation of an inverse discrete micellar Fd3m cubic phase, which usually [...]

Synthesis and Magnetic Properties of Polyaniline-Based Magnetic Nanocomposites for EMI Applications

Renteria B., Singhal R., Calderon E., Tomar M.S., Banerjee J., University of Puerto Rico, PR

we have synthesized composite of polyaniline (PANI) with manganese-zinc-ferrite (MnXZn1-XFe2O4) nanoparticles. PANI was synthesized by polymerization of aniline in the presence of ammonium peroxydisulfate and HCl. Electrical conductivity of bare PANI pellets averaged 0.8044 (Ω·m)-1. [...]

Coupling of CdSe/ZnS quantum dots: among themselves and with matrices

Liu K., Tsu R., University of North Carolina at Charlotte, US

We investigate the photoluminescence (PL) properties of CdSe/ZnS QDs deposited on Si, fused silica, Au film, and silica nanospheres. The red shifts of the PL peak were observed with increasing density of QDs on various [...]

Processing and Characterization of Epon 862 reinforced with functionalized MWCNT’s

Theodore M., Hosur M.V., Thomas J., Jeelani S., Tusekgee University, US

In the current research work, functionalization of pristine MWCNTs was performed by oxidation in acid solution (MWCNT-COOH), direct-fluorination (MWCNT-F), and amino-functionalization (MWCNT-NH2). An epoxy-nanocomposite material was developed through the use of functionalized Multi-wall Carbon Nanotubes [...]

The development of nanotechnology is closely related to the new economy full with high tech products towards 21st century. As a new material, the nanoparticle has certainly caught the imaginations of researchers around the world. [...]

Polyvinyl Alcohol (PVA)/Layered Silicate Nanocomposite Approaches for Organic Passivation Layers in Organic Thin Film Transistors

Ahn T., Suk H.J., Yi M-Y, Korea Reserch Institute of Chemical Technology, KR

Organic thin-film transistors (OTFTs) have been demonstrated as promising candidates for flexible displays, smart cards (badges), and gas sensors. These applications with organic electronics offer many advantages, such as light weight, low cost processing, and [...]

Closed form Exact Analytical Solutions for Effective Mechanical Properties and Responses for Nanotube Reinforced Nanocomposites

Askari D., Ghasemi-Nejhad M., University of Hawaii at Manoa, US

In this paper, analytical and numerical approaches are employed to investigate the effective axial mechanical properties and mechanical behavior of a three-phase composite cylindrical model, representing a unit cell for a polymer nanocomposite reinforced by [...]

The Effect of Starch Structure on Starch-based Nanocomposite

Zhou J.H., Hanna M.A., South China Agricultural University, CN

The effect of starch structure on starch based nanocomposite Starches, including high amylose cornstarch, normal cornstarch, and waxy cornstarch, were gelatinized and mixed with nanoclay aqueous dispersion and different amount plasticizer. The mixtures were then [...]

Polypyrrole-Organoclay Nanocomposites for Gas Sensors

Magaraphan R., Thuimthad A., Chulalongkorn University, TH

Polypyrrole (PPy) was synthesized in the presence of octadecylammonium-montmorillonite (OC-MMT) 1-9 wt% using ferric chloride as an initiator to result the intercalated nanocomposites. The synthesized PPy and its nanocomposites were tested for volatile organic gases; [...]
