Flame Deposition of Superhydrophobic and Superhydrophilic Nanoparticle Coatings on Paperboard Materials

Aromaa M., Haapanen J., Teisala H., Tuominen M., Stepien M., Saarinen J.J., Toivakka M., Kuusipalo J., Mäkelä J.M., Tampere University of Technology, FI

Liquid Flame Spray is one of the flame aerosol methods for the nanoparticle synthesis. Here, it is used in depositing the particles directly on a moving roll-to-roll substrate. The deposition process is performed in a [...]

Continuous synthesis of highly-specific silicon nanopowder on the pilot-plant scale

Hülser T., Schnurre S.M., Schulz C., Wiggers H., Institute of Energy and Environmental Technology (IUTA), DE

In this work we present the formation process of crystalline and amorphous nanostructured silicon made from a continuously operating hot-wall reactor synthesis process. In this reactor, silicon particles are synthesized at variable operating conditions varying [...]

Pilot-scale Nanoparticle Manufacture

Wegner K., Grohn A., Multer S., ETH Zürich, CH

A fully automated pilot plant for nanoparticle manufacture by flame spray pyrolysis is presented that allows continuous production of nanopowders at rates up to 500 g/h. For the example of zirconia the scale-up from the [...]

Synthesis, Characterization and Toxic Metal-Binding Ability of Poly(γ-glutamic acid)-coated Superparamagnetic Nanoparticles

Chen B.H., Inbaraj B.S., Fu Jen University, TW

Superparamagnetic iron oxide nanoparticles (SPIONPs) coated with a non-toxic, edible biopolymer poly(-glutamic acid) (PGA-coated SPIONs) were synthesized by co-precipitation method, characterized and evaluated for their possible toxic metal-binding ability in the treatment of metal intoxication [...]

Stability of Functionalized Magnetic Particles in a Physiologic Fluid

Baca Ramos K., Martínez Pérez C.A., Camacho Montes H., Olivas Armendáriz I., Martel A., García-Casillas P.E., Universidad Autonoma de Ciudad Juarez, MX

Magnetic materials are widely used in biomedical applications such as magnetic separation, magnetic resonance imaging, drug delivery and hyperthermia. In these applications the nanoparticles are functionalized in a core/shell type with polymeric materials which contains [...]

Nanotechnology systems for drug delivery, multi-modal targeting and imaging of tumors

Singh M., Patel A.R., Lim E., Zhang N., Francis K., Safe S., Florida A & M Univeristy, US

Cancer is one of the leading causes of deaths (1.6 million deaths annually) in USA. Despite recent advances in chemotherapy, the survival rates in lung cancer patients are unsatisfactory due to limited efficiency of systemic [...]

Carbon Nanotube Thin Film based Fuel Cell to Reach DOE Targets

Palanisamy R., Itkis M.E., Bekyarova E., Haddon R.C., Carbon Solutions Inc, US

We demonstrate a prototype polymer electrolyte membrane fuel cell (PEMFC) that reaches the technical targets set by DOE for 2015. We show that the Pt required for automotive fuel cells can be reduced by an [...]

Dependence of electrical and thermal parameters of CNT bundles on their geometry

Jain N., Solid state physics lab, IN

Carbon nanotube bundles are being considered for VLSI interconnect applications due to their superior electrical and thermal properties. In this paper we report the variation in electrical and thermal conductance as well as inductance of [...]

Plasmon Generation by Excitons in Carbon Nanotubes

Bondarev I.V., Antonijevic T., North Carolina Central University, US

Optically excited excitons are theoretically demonstrated to generate and amplify plasmons in individual semiconducting carbon nanotubes. Plasmons are coherent charge density waves due to the periodic opposite-phase displacements of the electron shells with respect to [...]

Length amplification of single walled carbon nanotubes for the enrichment of chiral specific nanotubes

Orbaek A.W., Barron A.R., Rice University, US

At Rice University there is a large body of work relating to the development of an “Armchair Quantum Wire”. This would be composed of armchair SWNTs spun into a fiber, that could span global distances. [...]
