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 [...]

Mechanisms of Photonic Curing™: Processing High Temperature Films on Low Temperature Substrates

Schroder K.A., NCC Nano, LLC, US

Photonic Curing uses flashlamps to thermally process a thin film at high temperature on a low temperature substrate without damaging it. This has utility in printed electronics, where high temperature curing is generally equated to [...]

A Study of Inorganic-Polymer Hybrid Films for Various Surface Functionalization

Park B-S., Lui Z., Jin H.S., Yang S.-Y., Chungnam National University, KR

The PEM coatings were applied on magnetic particles and the deposited films were examined by zeta-potential analysis and fluorescence microscope. Additionally, we utilized layer-by-layer deposition method to modify the surface of the micro-channel of the [...]

Ink-jet printed ZnO Nanoparticle Thin Films for Sensing Applications

Hartner S., Khalil A.S.G., Ali M., Winterer M., Wiggers H., University Duisburg-Essen, DE

Stable aqueous dispersions of ZnO NPs are successfully prepared with a new polymeric stabilizer. The dispersions are stable for at least 2 months without any observable sedimentation. The zeta potential and the size of the [...]

Experiments to Investigate Electromagnetic Shielding Performance of Polyaniline-Coated Thin Films

Kim B.R., Lee H.K., Korea Advanced Institute of Science and Technology (KAIST), KR

Many studies on electromagnetic wave shielding/ absorbing materials have been performed. In particular, studies of novel materials have been carried out as an alternative to conventional shielding materials such as metallic materials. Recently, the investigation [...]

Soft plasma polymer coatings based on atomic polymerization

Cech V., Trivedi R., Lichovnikova S., Hoferek L., Brno University of Technology, CZ

Plasma polymerization is a thin film-forming process based on atomic polymerization. Plasma polymer films deposited from organosilicon monomers constitute a special class of dielectric coatings with controllable organic/inorganic character and cross-linking that enable optimization of [...]

Wide Area Deposition of Transparent Flexible Nanocomposites

Druffel T., Optical Dynamics, US

Our group has been involved in the deposition of thin film nanocomposites via spin coating in which the optical and mechanical properties of the composites is controlled by the volume packing of the inorganic nanoparticles. [...]

Thin-Film Deposition on Nanoparticles in Low-Pressure Plasma

Shahravan A., Matsoukas T., The Pennsylvania State University, US

To achieve the desirable optical, mechanical, thermal, and electrical properties that are unattainable in the nanoparticles alone, Matsoukas group uses plasma enhanced chemical vapor deposition technique, PECVD. Particles are introduced into two different reactors that [...]

Self Assembly of Colloidal Gold Nanoparticles on Diblock Copolymer Thin Film Templates

Adams S.M., Ragan R., University of California Irvine, US

Self-assembly of metallic nanoparticles were investigated for the development of field-enhanced chemical and biological detection devices with the capacity to achieve single-molecule level detection resulting from surface enhanced Raman scattering, associated with closely spaced noble [...]

Large area, directionally aligned single-walled carbon nanotube thin film by self-assembly and compressed sliding methods

Najeeb C.K., Lee J-H., Chang J., Kim J.H., Ajou University, KR

To fabricate large area directional arrangement of SWNTs, we employed two different methods such as self assembly of surface modified SWNTs by drop casting or spin coating and by compressed sliding of SWNT dispersion between [...]
