Inkjet Printing of High Index Zirconia Nanocomposite Materials

Healy M.D., Guschl P., Wang X., Weinstein M., Pixelligent Technologies LLC, US

Abstract High refractive index (RI) nanocomposites have properties which surpass traditional polymers while maintaining manufacturability. Nanocrystal-polymer nanocomposites, when inkjet-printed, are useful to many display components and aid the development of next generation displays. This paper [...]

Sunstone Nanocrystals from Intelligent Material Solutions® Inc. are a proprietary, novel series of rare earth-doped nanocrystals of small size, high quantum efficiency, and high photoluminescent intensity functionalized for use in industrial and life sciences applications. [...]

Gravimetric calibration for optical measurements of droplets-in-flight

Verkouteren J.R., Verkouteren R.M., Zeissler C.J., Verkouteren J.R., Verkouteren R.M., National Institute of Standards and Technology, US

We report gravimetric measurements of droplets, traceable to the SI, that enable the correction and calibration of optical measurements routinely used to monitor and control the dispensing of droplets from inkjet printers. This innovation results [...]

Effect of particle presence on gas phase temperature in the flame spray pyrolysis

Engel S.R., Gao Yi, Koegler A.F., Kilian D., Seeger T., Peukert W., Leipertz A., Department of Engineering Thermodynamics, DE

For the production of manufactured nanoparticles at a commercial scale flame processes are most frequently used. An important basis for understanding the complexity of this process is the characterization of the combustion process in dependence [...]

Early Stages of Particle Formation by in-situ UV-Vis and HRS

Schürer B., Segets D., Peukert W., University of Erlangen-Nuremberg, DE

We present a new approach for the study of early states of particle formation that can be applied also for precipitation processes that occur on a millisecond timescale. A T-shaped micro-mixer is used to precipitate [...]

In-situ Surface Characterization of Nano- and Microparticles by Optical Second Harmonic Generation

Schürer B., Wunderlich S., Peschel U., Peukert W., University of Erlangen-Nuremberg, DE

We use optical Second Harmonic Generation (SHG) to probe different kinds of surface properties of dispersed particle systems in in-situ and in real time. Examples for applications are the direct study of molecular adsorption at [...]

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 [...]

Fabrication and optical properties of nanoscale arrays of Au and Pd in polymers

Atre S.V., Bhowmik S., Valmikanathan O.P., Ostroverkhova O., Oregon Nanoscience & Microtechnologies Institute, US

We report the fabrication of regular repeat structures of Au and Pd square islands embedded in polymethyl methacrylate (PMMA) and polycarbonate (PC). Using focussed ion beam (FIB), square islands were machined over a 5 micron [...]

High speed Resonant Tunneling Diode based on GaN & GaAs: A modelling & simulation approach

Arjun V., Sikdar D., Chaubey V.K., Birla Institute of Technology & Science, IN

The investigation of tunneling of particles through potential barriers in semiconductor quantum wells has recently attracted much attention. Special focus is laid on resonant tunneling structures because of its importance in the field of nanoscience [...]

Nanotechnology Based Optical Power Control Devices

Donval A., Nemet B., Oron M., Oron R., Oron M., Oron R., Shvartzer R., KiloLambda Technologies Ltd., IL

We are taking advantage of the unique capabilities of nanoparticles guest embedded within dielectric host matrices for field enhancement effect in developing next generation of non-linear components and devices to passively control and regulate optical [...]
