Porous filter with spatially graded response

Krause K.M., Hawkeye M., Brett M., University of Alberta, CA

Glancing Angle Deposition (GLAD) has become a common technique for producing thin porous films with various structural features. In the current work, we have further modified GLAD in order to create porous structures that have [...]

Self-assembly of Carbon Nanotubes on Large Structures and on Ceramics

Karwa M., Brukh R., Saridara C., Wang Y., Iqbal Z., Mitra S., New Jersey Inst. of Technology, US

Self-assembly techniques as related to carbon nanotubes (CNTs) is explored. The first is the self-assembly on the inside wall of stainless steel tubings using C2H4 as the carbon source and the iron nanostructures in the [...]

Current-induced Breakdown of Carbon Nanofibers Under Vacuum and Atmospheric Conditions

Kitsuki H., Ngo Q., Suzuki M., Gleason K., Wilhite P., Cassell A.M., Moylan C.R., Li J., Yang C.Y., Santa Clara University, US

Current-induced breakdown phenomena of carbon nanofibers (CNFs) for the development of carbon-based interconnects are investigated to reveal current-carrying capacity and reliability of CNF devices. Scanning transmission electron microscopy (STEM) techniques are developed to study the [...]

Development of a novel material for reversible hydrogen storage

Titus E., Coelho M.C., Cabral G., Madaleno J.C., Shokuhfar T., Gracio J., University of Aveiro, PT

An efficient hydrogen storage material is a hot topic of discussion among modern scientific community worldwide. The efficiency of the hydrogen storage material is measured on the basis of their adsorption enthalpy. Low adsorption enthalpy [...]

Structural and magnetic characterization of 3d metal clusters embedded in fullerite matrices

Teodorescu C.-M., Macovei D., National Institute of Materials Physics, RO

Metal clusters embedded in fullerite matrices are produced by high vacuum co-evaporation. XPS and X-ray absorption revealed that the metal clusters are protected against contamination. XRD analysis is used to determine the average custer size, [...]

A novel technique for purification and segregation of CNTs for nano-thin film studies

Chaves J., Mangir T., CSULB, US

An Investigation Of Carbon Nano-tubes For Bio And Nano-material Applications Invited Paper Juan Chaves, Tulin Mangir EE Department, College of Engineering, CSULB, LB, CA, USA. Contact: Dr. Tulin Mangir (temangir@csulb.edu) We describe an approach to [...]

Zinc Gallate [ZnGa2O4] thin film phosphors for Field Emission Display application

Yun Y.H., Jung J.H., Choi J-S, Dongshin University, KR

Field emission display (FED) is being expected as one of the most promising FPD technologies. The practical FED technologies are requiring the improvements in durability, quality and reduction in manufacturing cost for the low voltage [...]

Nanostructured photocatalytic TiO2-xNx thin films prepared by reactive magnetron sputtering

Teodorescu C.-M., Luca D., National Institute of Materials Physics, RO

Nitrogen-doped titania films were grown by magnetron sputtering. XPS analysis was used to identify the nitrogen content and the oxygen stoichiometry of the samples. XANES evidenced an increase of the Ti 3d charge density. XRD [...]

Atmospheric Pressure Ion Deposition – Selected applications

Nußbaumer L., Saf R., Piber M., Institute for Chemistry and Technology of Organic Materials, AT

Atmospheric Pressure Ion Deposition: a novel experimental setup allows the processing of various materials (e.g. polymers, small molecules, nanoparticles and biomolecules) into thin structured films.This method generates by means of electrostatic forces a fine dispersed [...]

Photoactive titania and nanoparticulate silver-titania composite thin films as potent antimicrobial coatings

Page K., Parkin I.P., Wilson M., University College London, UK

Nanocrystalline titania (anatase) and Ag-doped titania (anatase) coatings were prepared on glass microscope slides by a sol-gel dip-coating method. The resultant coatings were characterised by X-ray diffraction, XANES, Raman, SEM/WDX, XPS and UV visible techniques [...]
