Determining the Quality of Asphalt Emulsions by Size and Zeta Potential

Ragheb R., Park K., Nobbmann U., Casola J., Malvern Panalytical, US

Asphalt binder emulsions have proven to be an environmentally friendly, energy efficient, and cost-effective alternative to hot asphalt binder mixtures [1]. They are typically used for roadway resurfacing where they are employed as an adhesive [...]

Thorough Characterization of Liposomes by Complementary Light and X-Ray Scattering Techniques

Ragheb R., Bolze J., Taylor G., Tamaddoni N., Griffiths D., Nobbmann U., Malvern Panalytical, US

Liposomes are spherical vesicles with an aqueous core enclosed by one or more phospholipid bilayers or lamellae and are frequently classified based on their size and number of bilayers [1]. They are often used in [...]

Morphology and Size Control of Mesoporous ORMOSIL Particles

Jung G.I., Kim J-S, Koo S.M., Hanyang University, KR

Mesoporous ORMOSIL particles with tailored morphology and/or controlled size were prepared by a simple two-step process. The first step, synthesis of monodisperse ORMOSIL particles with multi-layered structure, involved a one-pot process in an aqueous solution [...]

Nanomaterial Characterisation Challenges

Kippax P.G., Clarke P.G., Murphy C.C., Kaszuba M., Malvern Instruments Ltd, UK

There has been a large amount of research and investment into the toxicological effects of nanomaterials on the environment and there is – as yet – no definitive findings on the relative weighting and importance [...]

Comparing Nanorulers for Nanoparticles

Bodycomb J., Bath F., Treviranus I., Park K., Hou A., Horiba Scientific, US

Nanoparticle development and manufacturing require particle characterization to determine if design or quality goals are being met. Scattering techniques are the method of choice for analyzing average size and size distribution. There are two light [...]

Size and Count of Nanoparticles by Scattering and Fluorescence Nanoparticle Tracking Analysis (NTA)

Griffiths D., Hole P., Smith J., Malloy A., Carr B., NanoSight, US

A novel addition to a technique for the analysis of nanoparticles in a suspension is described. The Nanoparticle Tracking Analysis (NTA) technique sizes individual nanoparticles, based on their Brownian motion. Unlike classical light scattering techniques, [...]

Size Effect on Nano-Droplet Spreading on Solid Surface

Sedighi N., Murad S., Aggarwal S., University of Illinois at Chicago, US

In this paper MD simulation has been performed to study the behavior of nano-sized non-polar argon droplets spreading on a solid surface. Three different sizes of the nano-droplet have been examined with the diameters of [...]

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 [...]

Effect of particle size on the mechanical properties of polymer matrix nanocomposite

Zhou Y.X., White E.T, Jeelani S., Tuskegee University, US

In the present investigation, we have studied effect of inclusions size on mechanical properties of nanocomposite materials containing SC-15 epoxy resin and TiO2 particles. Micro sized particles have little effect on modulus and strength of [...]
