Polyurethane Nanocomposites Containing NCO-Functionalized Carbon Nanotubes and NCO-Functionalized Nanoclays

Nguyen T., Granier A., Pellegrin B., Celina M., NIST, US

Mechanical property, UV resistance, and oxygen permeation performance of automobile polyurethane (PU) coating containing NCO-functionalized (MWCNTs and nanoclays) have been measured. A novel method was used to functionalize CNTs and nanoclays using a diisocyanate in [...]

Epidermal Growth Factor Receptor-Targeted Engineered Gelatin Nanovectors for Gene Delivery and Transfection

Magadala P., Amiji M., Northeastern University, US

Purpose: Over 80% of human pancreatic cancer expresses epidermal growth factor family of receptors on the cell surface. In this study, we have examined the potential of EGFR-targeted gelatin-based engineered nanovectors (GENS) for plasmid DNA [...]

Nano cellulose crystallites: optical, photonic and electro-magnetic properties

Simon D., Kadiri Y., Picard G., Ahuntsic College, CA

(NCC) are tubes, about 200 nm long and 20 nm in diameter. This is a natural product, found in wood. It is separated by paper mills from long fibers, and rejected in mass volumes. In [...]

Real time Crystallization of Nanoparticles Filled Natural Rubber Under Stretching

Carretero-González J., Verdejo R., Toki S., Hsiao B.S., Giannelis E.P., Lopez-Manchado M.A., Polymer Science and Technology Institute, ES

Polymer nanocomposites (PNCs) represent an alternative new class of materials compared to conventional filled polymers or polymer blends, as they can possess enhanced properties through nanoscale reinforcement.[1] A great deal of efforts have been devoted [...]

Nanoparticle Measurement by Spectroscopic Mie Scattering

Trutna R., Liu M., Chamberlin D., Hadley J., Agilent Technologies, US

We present a spectroscopic technique for measuring particle size. The technique utilizes a UV-Visible spectrophotometer to measure the attenuation spectrum of a particle dispersion due to scattering. Using the Mie scattering theory, we compute the [...]

Ultrasonic Pulsed Doppler (USPD): A Novel Ultrasonic Method for Characterizing Suspensions of Nanoparticles

Africk S.A., Colton C.K., Prodyne Corp., US

This paper describes a novel means for particle characterization, the Ultrasonic Pulsed Doppler (USPD) system. This system uses a single transducer to measure ultrasonic backscatter from moving particles to perform measurements of particle concentration, size [...]

An Embedded Atom Method for Alloy Nanoparticles

Shan B., Hyun J., Wang L., Yang S., Kapur N., Nicholas J.B., Nanostellar Inc., US

We present the development and application of a high-accuracy embedded atom method (EAM) potential for the simulation of metal alloy nanoparticles. The potential was parametrized by a large set of density functional theory (DFT) calculations [...]

Non-destructive 3D Imaging of Nano-structures with Multi-scale X-ray Microscopy

Wang S., Lau S.H., Tkachuk A., Druewer F., Chang H., Feser M., Yun W., Xradia, Inc., US

X-ray microscopy offers a unique combination of large penetration depth, high resolution, and high sensitivity to elemental composition. When combined with computed tomography (CT) techniques, the full three-dimensional structure of a sample can be obtained [...]

NanoZeolites – porous nanomaterials for cleantech, encapsulation and triggered release applications

Daniell W., Sauer J., Kohl A., NanoScape AG, DE

Recent advances in hydrothermal synthesis techniques and procedures to modify the surfaces of the particles have led to the development of a new class of material – the NanoZeolites. The availability of porous, nanocrystalline materials [...]

Nanoscaled Mg(OH)2 Used as Flame Retardant Additive

Zhou B., Zhou Z., Wu Z., Fransson M., Zhou B., Zhou Z., Headwaters Technology Innovation LLC, US

Headwaters Technology Innovation (HTI) has applied aqueous colloidal chemistry with great success in the development of “bottom-up” nanomaterials and nanotechnologies. One such material is a nano-scaled magnesium hydroxide, NxCat® Mg(OH)2, which is primarily used as [...]
