Flame-assisted synthesis of nanoscale, amorphous and crystalline, spherical BiVO4 with visible-light photocatalytic activity
César Pulgarin, Nikola Castillo, Andre Heel
The synthesis of bismuth vanadate (BiVO4) nanoparticles has drawn considerable attention to their application as a visible-light-driven photocatalyst. Several techniques are addressing the enlargement of surface area, but some of them can cause impurities ...
Elsevier2010Applying combined field integral equation technique to analyze quasi-waveguide structures
Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad
In this paper a detailed mathematical procedure is described to evaluate modal scattering parameters conventionally defined in planar multilayered structures excited by wave ports. Combined Field Integral Equation technique is implemented and solved using ...
2009Experimental and Theoretical Investigation of Degradation Mechanisms in SOFC Electrodes
Christos Comninellis, Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Pietro Tanasini
Performance degradation data obtained on single solid oxide fuel cells tested at 850°C with air and humidified H2 and using Ni-YSZ anode supported cells are presented. Microscopic investigation is carried out on both anode and cathode to quantify variation ...
2009Characterization of surface functional groups present on laboratory-generated and ambient aerosol particles by means of heterogeneous titration reactions
Michel Rossi, Michel Guillemin
A Knudsen flow reactor has been used to quantify surface functional groups on aerosols collected in the field. This technique is based on a heterogeneous titration reaction between a probe gas and a specific functional group on the particle surface. In the ...
2009Multi-scale characterization of particle clustering in discontinuously reinforced composites
The applicability of a quantitative characterization scheme for cluster detection in particle reinforced composites is discussed. The method considers the pattern from the perspective of individual particles, so that even in a pattern that globally conform ...
2009Effect of natural organic matter and green microalga on carboxyl-polyethylene glycol coated CdSe/ZnS quantum dots stability and transformations under freshwater conditions
The influence of pH, ionic strength, presence of humic or alginic acids, extracellular polymeric substances (EPS), or freshwater microalga Chlorella kesslerii on the stability and transformation of carboxyl-PEG-CdSe/ZnS core/shell quantum dots (QDs) in ter ...
2009Surface enhanced Raman scattering of carbon nanotubes decorated by individual fluorescent gold particles
Klaus Kern, Marko Burghard, Kannan Balasubramanian, Tilman Assmus
Confocal optical microscopy was employed to study the effect of surface-enhanced Raman scattering on individual single-walled carbon nanotubes covered with isolated gold particles. The gold particles with diameters between 10 and 120 nm were deposited in l ...
2008Single-particle oxidation state and morphology of atmospheric iron aerosolsle
Sixty-three iron-containing particles from five field campaigns (PELTI, ACE-Asia, MILAGRO (urban location and aloft on NCAR C-130), INTEX-B) were characterized with scanning transmission X-ray microscopy and near-edge X-Ray absorption fine structure L-edge ...
2008Microparticle photometry in a CMOS microsystem combining magnetic actuation and in-situ optical detection
Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Cristiano Niclass, Emile Dupont, Stefano Pietrocola
We present a hybrid CMOS-based microfluidic system that combines magnetic actuation of microparticles with in situ optical detection using single photon avalanche diodes (SPADs). The decoupling of the principles used for actuation and sensing permits a hig ...
2008Internal spin-wave confinement in magnetic nanowires due to zig-zag shaped magnetization
We perform broadband spin-wave spectroscopy on thin submicrometer-wide Ni80Fe20 magnetic wires. Intentionally, we apply the in-plane magnetic field under an angle that is a few degrees off with respect to the in-plane hard-axis direction. In an intermediat ...
