Counting and measuring micro and nano particles by using Fourier Interferometric Imaging

Saengkaew S., Garo A., Meunier-Guttin-Cluzel S., Grehan G., UMR CNRS 6614/CORIA, FR

The characterization of micro and nano particles suspensions is still a challenge, especially if very low concentration of particles mixtures are concerned. To reach this aim, optical techniques are attractive because they provide a fast [...]

Monitoring Strategy for Characterization of Airborne Nanoparticles

Niu J., Rasmussen P., Magee R., Nilsson G., Health Canada, CA

A major challenge in monitoring indoor exposures to nanoparticles is the selection and effective use of suitable instrumentation. Comparability, portability, response time, and reliability are important selection criteria in addition to reasonable cost. Amongst these [...]

Magneto-optic Response of Iron Oxide Nanoparticles under Pulsed and AC Fields

Syed M., Foulkes T., Rose-Hulman Institute of Technology, US

Reliable methods for studying the magnetization dynamics of metal ferrite nanoparticles (NP) are needed, as these particles are attractive candidates for biomedical applications such as in targeted drug delivery, imaging, and magnetic hyperthermia. We investigate [...]

Amplification of Surface Acoustic Waves in Graphene Film under DC Voltage

Roshchupkin D.V., Kononenko O.V., Tynyshtykbayev K., Insepov Z., Purdue University, US

An acoustoelectric effect has been experimentally studied in a graphene film fabricated on the top of a piezoelectric crystal of the lanthanum–gallium silicate family Ca3TaGa3Si2O14 (CTGS) grown by the Czochralski method. The unit-cell parameters were [...]

Carriers Transport in Quantum Dot Quantum Well Microstructures of Self-assembled CdTe/CdS/ligand Core-shell System

Li K., Yanshan University, CN

The photo-generation carriers’ transport characteristics in CdTe quantum dots (QDs) capped by ligand were probed using a combination of surface photovoltaic (Figure 1) and photoacoustic techniques. The results confirmed that the QDs were composed of [...]

A New Separation Metric for the Optimization of AF4 Separations of Polydispersed Nanomaterials

Galyean A.A., Vreeland W.N., Filliben J.J., Holbrook R.D., Weinberg H.S., University of North Carolina at Chapel Hill, US

The development of standardized and optimized methods to monitor the behavior of engineered nanomaterials (ENMs) in complex environments is considered a critical component in ENM risk assessment. Robust, rigorously optimized methods are currently lacking, in [...]
