Multifunctional Electrodes Based on MWNTs Sheets and Yarns
Carretero-González J., dela Cruz M.E., Fang S., Ferraris J.P., Baughman R.H., The University of Texas at Dallas, US
Solid-state fabricated carbon MWNTs sheets and yarns exhibit very high electrochemically accessible surface area, which combine with their high electronic conductivity and useful mechanical properties to make these materials attractive candidates for supercapacitor and artificial [...]
Multi-Scale Modeling of Polymer Nanocomposites
Due to the small size of nano-inclusions, their surface becomes an important factor determining the composite properties. For “microcomposites” (with inclusions larger than one micron) it is often sufficient to consider the phases’ bulk properties, [...]
Obtaining Fracture Properties by Virtual Testing and Molecular Dynamics Techniques
Fracture critical parts of aerospace structures must have adequate life to withstand the cyclic load environment throughout their service usage. The life analysis of these parts requires having fracture mechanics allowables that are obtainable through [...]
Extraction of Bulk Material Properties from Phonon Dispersion Spectra
Experimental characterization of mechanical behavior of nanostructures can be cumbersome and expensive. Design of nano-structured materials with properties tailored to meet macro-scale requirements invariably requires model-based understanding of the structure-to -property relationships. In this effort, [...]
Determination of Elastic and Thermal Properties of Nanocomposites by Fiber Embedment in Finite Elements
In this paper the impact of entangled and non-straight fibers in the determination of the effective elastic and thermal properties of polymer nanocomposite (PNC) is addressed. Most of the models in recent studies assume nanotubes [...]

Longo P., Costabile C., Grisi F., Siniscalchi G., Ciambelli P., Sarno M., Leone C., Sannino D., University of Salerno, IT
Recently, carbon nanotubes have attracted attention for their unique structural and electronic properties, which position them as one of the leading materials for a wide array of potential nanotechnological applications. The synthesis of homogeneuos polymeric [...]
Nano-Engineered Dielectrics for Energy Storage Solutions
We present a novel laser processing technique to produce nanodielectric films, which are based on polymer coated metal nanoparticles. The polymer-coated Au NP composite was spin-coated onto a nickel foil serving as the bottom electrode [...]
Using Nanoparticles and Carbon Nanotubes to Enhance the Properties of a Lead-free Solder
Nai S.M.L., Han Y.D., Jing H.Y., Tan C.M., Wei J., Gupta M., Singapore Institute of Manufacturing Technology, SG
Solders are used in various levels of electronic assembly sequence, whereby good electrical, thermal and mechanical performances of solder are necessary. With miniaturization of devices, diverse functional requirements and ever-stricter operating environments of devices, the [...]
Rheology, Microstructure, and Property of Polylactide/Clay Nanocomposites Prepared with SC-CO2 by Melt Compounding
The rheology, microstructure and mechanical properties of polylactide (PLA)/clay nanocomposites were investigated. The nanocomposites were prepared using a twin screw extruder with and without the aid of supercritical carbon dioxide. Results show that there exists [...]
Permittivity of BaTiO3 polymer composite with differing particle size distribution
In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]
