Photoacoustic Study of CdS quantum Dots for Photovoltaic Applications

Abdallah S., Al-Hosiny N., Badawi A., Taif University, SA

Recently, CdS quantum dots (QDs) have become one of the promising materials for high efficiency photovoltiac solar cell.. In this work we investigate the optical properties and photovoltaic characterization of CdS QDs -sensitized solar cells [...]

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 [...]

Raman Spectroscopy hyperspectral imager based on Bragg Tunable Filters

Marcet S., Verhaegen M., Blais-Ouellette S., Martel R., Photon etc., CA

A new type of Raman spectroscopy hyperspectral imager based on Bragg tunable filter has been developed by University of Montreal and Photon etc. The technology of Bragg tunable filter significantly reduces the acquisition time by [...]

Calculation of Nanoparticle Filler Content in Solid or Liquid Dispersions

Khalfin R.L., Cohen Y., Technion – Israel Institute of Technology, IL

Nano composites have unique properties which depend to a large extent on the quality of the nanoparticle dispersion. An outstanding issue is the quantitative measure of fillers that are actually dispersed to dimensions below a [...]

Multi-Parametric Surface Plasmon Resonance – A new technique to determine thickness and refractive index of thin and thick layers

Robinson M., Kuncova-Kallio J., Granqvist N., Sadowski J.W., BioNavis, LTD, US

Multi-Parametric(MP)-SPR empowers multidisciplinary research between life sciences and material sciences. Biochemists are moving from molecular-molecular interactions to molecule-material interactions, as seen in drug encapsulation or development of diagnostic kits. On the other hand, material science [...]

Spectroscopic study on the charge redistribution between Au and Ag in Au@Ag core-shell nanoparticles

Nishimura S., Anh D.T.N., Mott D., Ebitani K., Maenosono S., Japan Advanced Institute of Science and Technology, JP

Charge transfer in heteromeric structures such as Au@Ag core-shell nanoparticles (NPs) and Au@Ag@Au double-shell NPs was demonstrated using X-ray absorption near-edge structure (XANES) and X-ray photoelectron spectroscopy (XPS) techniques. XANES analyses confirmed that the d-orbital [...]

Design of a Small, Battery-Operated Nanoparticle Sizer

Erickson K., Johnson J., Grose M., Kolb J., Morell S., Caldow R., TSI Incorporated, US

A small, portable nanoparticle sizer has been developed to provide an affordable method to measure nanoparticle size distributions. The new nanoparticle sizer incorporates a SMPS Spectrometer into a chassis that is <1 cu.ft. The instrument [...]

Multi-Parameter Characterization of Nanoparticle Dispersions by Size, Count and Scattering Intensity

Griffiths D., Bernt W., Hole P., NanoSight USA, US

Nanoparticle Tracking Analysis (NTA) is a method that has gained increasing popularity for the study of nanoparticle dispersions, providing high-resolution particle size analysis as well as a direct measure of particle count or concentration. By [...]

Seeing the invisible – ultrasonic force microscopy for true subsurface elastic imaging of semiconductor nanostructures with nanoscale resolution

Kolosov O.V., Dinelli F., Krier A., Henini M., Hayne M., Pinque P., Lancaster University, UK

Scanning probe microscopes (SPM’s) are indispensable in modern nanoscale science but ability of SPM’s to look below the surface is unavoidably limited. In spite of developments based on Ultrasonic Force Microscopy (UFM) a true subsurface [...]
