Fabrication and Thermomechanical Characterization of CNF-Filled Polyester and E-Glass/Polyester Nanophased Composites

Hossain M.E., Hossain M.K., Hossain M.E., Hossain M.K., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

A high intensity ultrasonic liquid processor was used to infuse CNFs into the polyester matrix which was then mixed with catalyst using a high speed mechanical agitator. Results showed the significant improvement of mechanical properties [...]

Fabrication of bulk Al-TiB2 nanocomposite by spark plasma sintering of mechanically alloyed powder

Sadeghian Z., Enayati M.H., Beiss P., Shahid Chamran University, IR

In situ Al-TiB2 nanocomposite was synthesized by mechanical alloying (MA) of pure Ti, B and Al powder mixture and consolidated by spark plasma sintering (SPS).The structural characteristics of powder particles and sintered samples were studied [...]

Synthesis and Characterizations of nano sized Barium hexa-ferrites using sol gel method

Iqbal M.A., Mir A., Punjab University, PK

Nanosized Barium Hexaferrites were synthesized by sol gel auto combustion method. Samples of different composition with varying molar ratio of metal nitrates and citric acid i.e. (MN_A= 0.5, 1, 1.5, 2, 3) were prepared. Pellets [...]

In-situ techniques in optical spectroscopy for the analysis of carbon nanotubes

Freihofer G., Mohan B., Raghavan S., University of Central Florida, US

Optical Spectroscopy has shown promise as a fundamental characterization tool for carbon nanotubes (CNTs). With the potential of CNTs being utilized for aerospace applications, in-situ techniques including temperature and strain measurements with spectroscopy, are gaining [...]

High Strain Rate Compression Behavior of Conventional and CNF-Filled-Nanophased Glass/Polyester Composites

Hossain M.E., Hossain M.K., Hossain M.E., Hossain M.K., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

A high intensity ultrasonic liquid processor was used to infuse carbon nanofibers (CNFs) into polyester matrix that was then mixed with hardener using a high speed mechanical agitator. The trapped air and reaction volatiles were [...]

Effect of compounding method on the thermal, mechanical, and molphological properties of Polypropylene-Nanoclay nanocomposites

Nader J., Dagher H., Gardner D., Duguay A., Parent J., Kiziltas A., The University of Maine, US

This study investigates the effects of direct melt compounding, masterbatch dilution and compatibilzer addition on the mechanical and morphological properties of organoclay nanocomposites. Nanoclay reinforced Polypropylene composites were manufactured using melt mixing with and without [...]

Synthesis of Magnetically Separable Photocatalyst-TiO2/SiO2 coated Mn-Zn Ferrite-and its Photocatalytic study

Laohhasurayotin K., Pookboonmee S., Viboonratanasri D., National Science and Technology Development Agency, TH

A manganese-zinc ferrite as a magnetically separable photocatalyst was synthesized by simple co-precipitation and the following silica as well as titanium dioxide coating through sol-gel techniques. The nanoparticle was found to be well induced by [...]

Method of enhancing polyaniline conductivity using different oxidizing agents as dopant

Iqbal M.A., Manzoor S., Punjab University, PK

The synthesis and characterization of Polyaniline pellets has been analyzed by using three different oxidizing agents like Ammonium per oxy disulphate (APS), Hydrogen per oxide and Potassium dichromate. Samples of different molar ratios of Aniline [...]

Acyl ascorbate in enzymatic synthesis: Industrial use as a food nano additive

Sharma R., Pathak Y., Florida State University, US

Nanoadditive Acyl ascorbates were synthesized through the condensation of various fatty acids with L-ascorbic acid using immobilized lipase in a water-soluble organic solvent, and their properties as food additive were examined. The optimal conditions, which [...]

Effects of Non-radiative energy transfer processes on the visible upconversion in ZrO2:Yb3+/Er3+ nanocrystals

Meza O., Diaz-Torres L.A., Salas P., De la Rosa E., Solis C.D., Centro de Investigaciones en Optica A C, MX

The luminescence dynamics of both near infrared (NIR) and visible (VIS) emission of Yb3+,Er3+ in nanocrystalline ZrO2 is studied. It is found that upconversion emission is dominated by back transfer processes over direct Yb to [...]
