Quantum Correction for the Current-Based One-Particle Monte-Carlo Method

Brugger S.C., Wirthmueller A., Schenk A., ETH Zürich, CH

In a previous work we proposed a one-particle Monte-Carlo method based on equations for the currents. Our method has the advantage of being able to take into account arbitrary generation-recombination processes self-consistently. Recently, we extended [...]

Two-nozzle flame synthesis of tailored Pt/Ba/Al2O3 nanoparticles for NOx storage-reduction

Strobel R., Piacentini M., Maciejewski M., Baiker A., Pratsinis S.E., ETH Zürich, CH

NOx storage reduction (NSR) catalysts are applied for the abatement of NOx from engines operating under lean conditions, where conventional TWC catalysts are inefficient. Here, a novel two-nozzle flame spray pyrolysis (FSP) process was developed [...]

Electrophoretic RNA Transport Through Transmembrane Carbon Nanotubes

Zimmerli U., Koumoutsakos P., ETH Zürich, CH

We study electrophoretic transport of RNA through carbon nanotubes embedded in membranes using molecular dynamics simulations. % Doped and naked carbon nanotubes are inserted into a dodecane membrane and a dimyristoylphosphatidylcholine lipid bilayer and we [...]

Atomistic-Continuum Simulations of Carbon Nanotubes in LIquids

Koumoutsakos P., Kotsalis E., Walther J.H., Dupuis A., ETH Zürich, CH

We consider atomistic continuum simulations of carbon nanotube configurations embedded in flows of dense liquids. We consider Schwartz domain decompositions algorithms implying that non-periodic boundary conditions are imposed on the molecular system. In these algorithms, [...]

Sensing of Organic Vapors by Flame-Made TiO2 Nanoparticles

Teleki A., Pratsinis S.E., Kalyanasundaram K., Gouma P.I., ETH Zürich, CH

Nanostructured anatase TiO2 was produced by flame spray pyrolysis (FSP) and tested for sensing of volatile organic compounds and CO at 500 °C. The as-prepared powders were characterized by transmission/scanning electron microscopy, x-ray diffraction and [...]

From Helical Starch Inclusion Complexes to Supramolecular Starch Assemblies

Conde-Petit B., Nuessli J., Heinemann C., Escher F., ETH Zürich, CH

Starch, in particular the linear amylose fraction has the ability ot form helical inclusion complexes with suitable guest molecules like monoglycerides, linear alcohols, lactones or terpenes. The helical amylose segments have a strong tendency to [...]

Cubic or monoclinic Y2O3:Eu3+ nanoparticles by flame spray pyrolysis

Camenzind A., Strobel R., Pratsinis S.E., ETH Zürich, CH

Continuous, single-step synthesis of cubic monocrystalline Y2O3:Eu3+ nanophosphor particles (10 -20 nm in grain diameter) is achieved by flame spray pyrolysis (FSP). The effect of FSP process parameters on product particle characteristics was investigated by [...]
