The real-time, simultaneous analysis of nanoparticle size, zeta potential, count, asymmetry and fluorescence

Carr R., Hole P., Malloy A., Smith J., Weld A., Warren J., NanoSight Ltd, UK

A new nanoparticle sizing and characterisation technique is described which allows nanoparticles in a suspension to be individually but simultaneously detected and analysed in real time using a low cost instrument. Nanoparticles of all types [...]

Nanoparticle characterization using light scattering technologies

Xu R., Beckman Coulter, Inc., US

To size smaller particles, dynamic light scattering (DLS) that utilizes time variation of scattered light from suspended particles to obtain their hydrodynamic size distribution is the most popular technology. For measuring turbid samples with particle [...]

Characterization of Different Surfaces Morphology in Heterogeneous Catalyst

Mukherjee R., Palazoglu A., Romagnolia J.A., Louisiana State University, US

Structures and property of surface are very important in different chemical, physical and biological process. The interaction between the reactant molecules (adsorbate) and the surface are important in the performance of the catalyst. Surface with [...]

Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D): Real-Time Characterization of Nano-Scale Interactions at the surfaces

Jaiswal A., Smoukov S., Poggi M., Grzybowski B., Q-Sense, Inc., US

There has been an increasing demand for analytical tools that can quantify the interaction and/or reaction of nano-scale particles, polymers as well as bio-molecules, with various surfaces. In-situ monitoring of structural and dynamic changes of [...]

Nanostructured LZO Films: Synthesis and Characterizations

Chen H-S, Kumar R.V., University of Cambridge, UK

Nanocrystalline lanthanum zirconium oxide (LZO) films have been successfully synthesized by a wet-chemical route, using dried lanthanum acetate, zirconium propoxide, propoionic acid, acetic acid glacial, and anhydrous methanol. X-ray 2 -scan diffraction patterns of the [...]

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 [...]
