Tomography-based radiative characterisation of decomposing carbonaceous heat shield materials

Sophia Haussener, Pénélope Leyland, Nikhil Banerji

This work evaluates the changes in radiative properties of two decomposing carbonaceous porous materials, each composed of two semitransparent, homogeneous and isotropic phases. The understanding of the complex dependence of macroscopic optical behaviour o ...

Ruthenium Dispersion: A Key Parameter for the Stability of Supported Ruthenium Catalysts during Catalytic Supercritical Water Gasification

Christian Ludwig, Frédéric Vogel, Gaël Peng

The catalytic supercritical water gasification of isopropanol (450 degrees C, 30 MPa) over Ru catalysts supported on carbon and metal oxides was performed in a fixed-bed plug flow reactor. The Ru loading was between 1.2 and 2%. The catalyst stability over ...

Optimizing Fueling Decisions for Locomotives in Railroad Networks

Michel Bierlaire, Prem Kumar

Even though rail transportation is one of the most fuel efficient forms of surface transportation, the cost of fuel constitutes one of the major categories of very high operating costs for railroad companies. In the United States, unlike in Europe, fueling ...

Carbon-graphene nanocomposite cathodes for improved Co(II/III) mediated dye-sensitized solar cells

Michael Graetzel, Jun Ho Yum, Morgan Mertens Stefik, Yelin Hu

Cobalt-based electrolytes have significantly advanced the tunability and performance of dye-sensitized solar cells. The typically used platinum cathodes are expensive and non-optimal for cobalt complexes, motivating the search for replacements. Graphene na ...

Transparent, conducting Nb:SnO2 for host-guest photoelectrochemistry

Morgan Mertens Stefik, Nripan Mathews, Maurin Cornuz, Takashi Hisatomi

Many candidate materials for photoelectrochemical water splitting will be better employed by decoupling optical absorption from carrier transport. A promising strategy is to use multiple thin absorber layers supported on transparent, conducting materials; ...

Syngas generation from n-butane with an integrated MEMS assembly for gas processing in micro-solid oxide fuel cell systems

Paul Muralt, Thomas Maeder, Bo Jiang, Dimos Poulikakos

An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-e ...

Adsorption and strain: The CO2-induced swelling of coal

Brice Tanguy Alphonse Lecampion

Enhanced coal bed methane recovery (ECBM) consists in injecting carbon dioxide in coal bed methane reservoirs in order to facilitate the recovery of the methane. The injected carbon dioxide gets adsorbed at the surface of the coal pores, which causes the c ...

Decoupling Feature Size and Functionality in Solution-Processed, Porous Hematite Electrodes for Solar Water Splitting

Kevin Sivula, Jérémie Minh-Châu Brillet

We introduce a simple solution-based strategy to decouple morphological and functional effects of annealing nanostructured, porous electrodes by encapsulation with a SiO2 confinement scaffold before high temperature treatment We demonstrate the effectivene ...

Hydrodynamic characterisation of a groundwater - surface water system and evaluation of BTEX, PAHs decay and heavy metals fate

Jordi Batlle-Aguilar

Most contaminated sites related to past industrial activities in Europe are adjacent to rivers and urbanized areas. These sites pose a major problem for water authorities and policy makers in terms of contaminants mobility, natural attenuation (or degradat ...
