Internal gelation at PSI. The past and the future

The Paul Scherrer Institute used to be very active in fuel fabrication R and D using the internal gelation process, which is a promising production method for spherical nuclear fuel. Such fuel kernels can be directly packed in a cylindrical cladding (a sph ...

Oxygenated organic functional groups and their sources in single and submicron organic particles in MILAGRO 2006 campaign

Satoshi Takahama, Shuai Liu

Fourier Transform Infrared ( FTIR) and X-ray Fluorescence (XRF) were used to measure organic functional groups and elements of submicron particles collected during MILAGRO in March 2006 on three platforms: the Mexico City urban area (SIMAT), the high altit ...

Development and benchmarking of a mechanical model for GFR plate-type fuel

Rakesh Chawla, Konstantin Mikityuk, Petr Petkevich

The reference fuel design currently being considered within the Generation-IV Gas-cooled Fast Reactor (GFR) project is a ceramic plate matrix with a honeycomb inner structure containing small fuel cylinders. The fuel is mixed plutonium-uranium carbide, whi ...

Multimodel ensemble simulations of tropospheric NO2 compared with GOME retrievals for the year 2000

Isabelle Bey, Jérôme Drevet

We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment (GOME) for the year 2000. The models used constant anthropogenic emissions ...

Compact 100 W stacks using thin components of anode supported cells and metal interconnects

Jan Van Herle, Raphaël Ihringer, Nicolas Badel, Nordahl Autissier, Diego Larrain, Joseph Sfeir

Progress on anode supported cell stacks (SOFCONNEX design, 50 m2 per cell) is presented. A 6-cell stack and a 8 cell-stack were mounted and tested with hydrogen fuel at 800 degre C, yielding 100 W el and 140 W el, corresponding to a power density of 1kW el ...

All-in-one bioprocess monitoring with a mid-IR spectroscopic sensor

Urs von Stockar, Ian William Marison, Christopher Cannizzaro, Martin Rhiel

Comprehensive and cGMP suitable bioprocess monitoring is still a challenge in microbial fermn. and cell culture process development. This paper discusses the exploitation of in-situ mid-IR spectroscopy in combination with partial least-squares anal. to mon ...

Changes in the atmospheric CH4 gradient between Greenland and Antarctica during the Holocene

Jérôme Chappellaz, Zheng Wang

We present a 650-year Antarctic ice core record of concentration and isotopic ratios (δ13C and δ18O) of atmospheric carbon monoxide. Concentrations decreased by ∼25% (14 parts per billion by volume) from the mid-1300s to the 1600s then recovered completely ...

Physiologic studies with the sulfate-reducing bacterium Desulfovibrio desulfuricans: evaluation for use in a biofuel cell

Christos Comninellis, Urs von Stockar, Ian William Marison

The growth kinetics of the sulfate-reducing bacteria Desulfovibrio desulfuricans Essex 6 was investigated under various conditions for potential use in a microbial fuel cell that recovers electrons generated from the redn. of sulfate to hydrogen sulfide. H ...

Dynamique des ressources et de l'utilisation des combustibles ligneux

In Senegal, as in most developing countries, domestic energy, much of which is used for preparing meals, is essentially drawn from fuelwood and charcoal. Extensive woodfelling for energy purposes causes severe damages to natural forests, already badly hit ...

Mitigation of Secondary Organic Aerosol Formation from Log Wood Burning Emissions by Catalytic Removal of Aromatic Hydrocarbons

Davide Ferri, Oliver Kröcher

Log wood burning is a significant source of volatile organic compounds including aromatic hydrocarbons (ArHC). ArHC are harmful, are reactive in the ambient atmosphere, and are important secondary organic aerosol (SOA) precursors. Consequently, SOA represe ...
