Comparative HRTEM Examination of Carbon Black and Soot Structures

Spry J.M., Compton S.P., MVA Scientific Consultants, US

Soot is a major source of airborne particulate and typically contains primary particles which are less than one micrometer in diameter. Soot particles form as an undesired combustion by-product originating from a variety of different [...]

Effect of Graphitic Filler Characteristics on the Percolation Behavior and Electrical Conductivity of Segregated Network Polymer Composites

Prystaj L., Lucas E.A., Alston K., Gerhardt R.A., Georgia Institute of Technology, US

Polymer composites can be used for applications such as electromagnetic shielding devices, self-regulating heaters, over temperature protection structures, temperature sensors, devices that can control and regulate the flow of electrical current as well as antistatic [...]

Effect of furnace temperature on the nucleation behavior and configurations of carbon nanoparticles

Ono K., Watanabe A., Matsukawa Y., Saito Y., Aoki H., Aoki T., Fukuda O., Aoki H., Aoki T., Yamaguchi T., Tohoku University, JP

The objective of the present study is to examine the impact of nucleation behavior and particle size distribution on morphology of carbon black. We used a fixed sectional approach applying the detailed chemical kinetic reaction [...]

Effect of Carbon Black and Silver Nanoparticle Loading on the Structural and Thermo-Mechanical Properties of Chitosan-Based Films

Blagg A., Perales-Perez O., Valentin R., University of Puerto Rico-Mayagüez, PR

This work addresses the synthesis and structural and thermo-mechanical characterization of bare and chitosan-based nanocomposite films synthesized via spin coating and sol casting techniques. The dependence of these properties as a function of the nature [...]

Thermal and Thermomechanical Properties of Epoxy Resin / Carbon Black Nanocomposites

Kanapitsas A., Zois H., Stimoniaris A.Z., Delides C.G., Technological Educational Institute Of Lamia, GR

The main aim of the present work is to study the mechanical and thermal properties of nanocomposite materials based on epoxy resin (ER) matrix reinforced with carbon black (CB) nanoparticles. The filler concentration was systematically [...]

One-Step Flame-Synthesis of Carbon-Embedded and -Supported Platinum Clusters

Ernst F.O., Büchel R., Strobel R., Pratsinis S.E., ETH Zürich, CH

Carbon-embedded or -supported Pt-clusters were made by a scalable, single-step flame spray pyrolysis (FSP) process. Pt-containing precursors was dissolved in xylene and sprayed and combusted in a controlled oxidation atmosphere resulting in nanostructured, carbon-embedded Pt-clusters. [...]

Heating efficiency of debundled carbon nanotubes compared to carbon black

Levi N.H., Carroll D.L., Wake Forest University, US

This work examines the amount of heat generated by single-wall and multi-wall carbon nanotubes to show how bundling and adequate dispersion of the tubes effects heat generation. Due to their high aspect ratio, nanotubes behave [...]
